Agreed. I'm hoping to hear back from Rafael soon about the dev_pm_qos thing. > > Additionally, it should not be on by default. I think I disagree with this. Since we don't have anything like laptop-mode AFAIK, I think we do want it on by default. For the server workloads that want to consume more idle power for faster response when idle, I think the servers should be willing to make this change, just like they need to disable overly deep C states, etc. (Admittedly, unifying the configuration would be nice.)

ShowMeMizzou.com has confirmed a new basketball commitment for the Missouri Tigers. On Friday afternoon, 2014 junior college SG prospect Kevin Punter 6'4" 170 Sedalia (MO) State Fair Community College contacted Missouri Head Coach Frank Haith to let him know that he was committing to Missouri.
"I committed to Missouri," said Punter. "I called Coach Haith today, and let him know I wanted to be a part of the Missouri Basketball program. He was excited! He said that I made his day. He said that he was excited to have me come in and be a part of the team."
Punter chose Missouri over offers from Baylor, Cincinnati, and Western Kentucky, among others.
As ShowMeMizzou.com reported earlier this week, Punter had taken an unofficial visit to Missouri on Tuesday. Punter said that after he visited Missouri on Tuesday, he talked with his family, and after thinking about it for a couple of days, he decided to go ahead and accept Missouri's offer.
Punter is planning to take an official visit to Missouri early in the Signing Period, and sign with Missouri at that time.
He will graduate from State Fait in May and begin classes at Missouri in June.

As with AI whining about their new 787s (big shock, I know, but still....), we are pretty used to hearing about the earliest models in a new type of airliner being overweight and a bit problematic. I am aware that pretty much every airliner type made slims down over time, but have there been any examples of a plane that didn't really change a great deal since the first plane rolled of the line? Also, how long are the early models generally expected to last compared to more mature designs? Are there many examples of very early examples of a type hanging around the longest, for instance? Is it always a given that the early planes will be cheaper too?
Grateful for your thoughs.

Venom 400 Performance Control Modules for Ford
The Venom 400 PCM is an add on comtrol unit that features it's own micro-controller. This module is connected to the throttle position sensor and the manifold absolute pressure sensor, and by monitoring the sensors output characteristics and modifying the input signal to the vehicles existing ECU. It improves horsepower by as much as 25% from 1,000-5,000 RPM. It is OBD II compatible. It also reduces flat spots, or delays timing, and automatic transmission downshift delay under sudden acceleration. The Venom 400 uses an 8-bit micro-controller that is capable of monitoring the various sensor inputs and modifying their outputs at more than 40 times per second. It even works with other performance chips that have been installed. It has an on/off switch so that smog certification is possible without detection of the unit. Installation requires basic hand tools and only four electrical connections.

Valentasia 2013 raises $230,000 for SMCHS
"The Best is Yet to Come" was the theme of Santa Margarita Catholic High School's annual benefit gala, Valentasia, held Saturday at the St. Regis Monarch Beach Resort in Dana Point. About 500 SMCHS families and friends attended the gala, which raised $230,000 for the school, with $99,000 of that specifically designated for tuition assistance. One of every five students depends on tuition assistance to attend the school.
Proceeds from the evening benefit the school's arts, academics and athletic programs. Specifically, a portion of funds raised will allow the school to build the infrastructure required to support a wireless learning environment. Santa Margarita is moving toward a tablet program putting a computer in the hands of every student and faculty member. Funds from the gala will be used to increase the school's wireless coverage making this program possible.
Entertainment for the evening included students from Encore, the school's traveling song and dance group, and a performance by SMCHS social studies teacher Mark Schumacher, who recently won Orange County's Funniest Person Contest. Live music by the 12-piece Rembrandt band had guests flooding the dance floor until just after midnight.
Auction items included golf packages, sports memorabilia, personal chef services, fine art and jewelry, shopping sprees, wine pairing dinners at Orange County restaurants, and getaways.
Amanda Coronado is the assistant director of advancement-communications at Santa Margarita Catholic High School.

HP Colour LaserJet CP2025dn
An HP colour laser printer suitable for in-house production of marketing materials.
- ImageREt 3600 half-toning technology, USB and Ethernet connectivity, small size, decent print speeds, USB-based administration interface
- Reds aren't accurate, banding issues, can't print reliably on glossy material, LCD panel won't display IP address
Bottom Line
There are a number of good and bad points about HP's Colour LaserJet CP2025dn. It isn't the best colour printer around but it can produce professional-looking documents.
Price$ 1,179.00 (AUD)
HP's Colour LaserJet CP2025dn is a mid-range printer with a small stature and fast print speeds. Photos won't dry properly when printed on glossy media, but for matte in-house marketing materials the printer is a viable choice.
It is roughly the same size as a low-end mono laser printer such as the Laser Shot LBP 3100B, but considering its relatively small stature the Colour LaserJet CP2025dn is surprisingly heavy and may require two people to move.
At $130 above the standard configuration, the dn model of the Colour LaserJet CP2020 series adds an automatic duplexer. Apart from this, the CP2025dn has the same features as the CP2020, including USB and Ethernet connectivity, ImageREt 3600 half-toning technology and a 540MHz processor. The printer also boasts 128MB of memory, which is user-upgradeable to 384MB through an easily accessible panel on the side of the unit.
The Colour LaserJet CP2025dn has a maximum paper input capacity of 300 sheets and an output capacity of 150 sheets. The maximum monthly duty cycle is quoted at 40,000 pages, though HP recommends printing 750-2000 pages; the printer is designed for low-volume use but can handle larger print jobs if necessary.
A control panel features a three-way navigation panel and a 2-line LCD that provides users with access to basic network settings and reports. Disappointingly, the printer refuses to show the IP address on the LCD itself: users have to waste paper by printing a network configuration report. Thankfully the report is only one page — reports from some high-end HP laser printers run to four pages or more.
Once connected to a network, users are able to access the printer's Web interface, which will be familiar to users of other HP laser printers released in recent years. The Colour LaserJet CP2025dn doesn't boast the most comprehensive options, lacking HTTPS and 802.1X security standards found in the higher end LaserJet P4515x. Still, it offers detailed statistics, reports, settings and e-mail alerts.
Like Dell's 2130cn, the Colour LaserJet CP2025dn also offers administration functions when connected to a PC using its USB interface. HP's Toolbox FX software mimics the Web interface, providing the same breadth of options without requiring the printer to be networked.
The Colour LaserJet CP2025dn can print at a respectable speed but it won't amaze you. It printed at a consistent speed of 20 pages per minute in our tests for both mono and colour documents, with the first page out in an average of 23.2sec. Printing A4 photos will slow down the first page out time to 53.5sec, after which pages will still churn out at 20ppm.
The quality of documents is quite good, largely due to the printer's use of the ImageREt 3600 technology, which allows the CP2025dn to print in halftones to produce a higher quality image. Mono text documents are very accurate, though characters are noticeably thinner and lighter than documents printed by HP's Colour LaserJet CM3530fs, despite both using ImageREt 3600. Colour graphical documents lack the gloss of higher-end colour laser printers, and colours are lighter than they should be. Nevertheless, these results actually proved to be more readable when combining text with graphics and coloured highlights.
HP offers a Photo Fix setting designed to enhance photo quality, but it still doesn't make it the CP2025dn an ideal choice as a photo printer. Though colour accuracy with yellows and blues is acceptable, reds aren't vibrant, resulting in inaccurate combination colours such as purple. Rampant banding is also apparent on darker images. Printing more than one photo at a time on glossy material and allowing them to rest upon each other leads to the toner material easily rubbing off, damaging the photos. The printer will be able to print professional-looking documents on higher density matte paper, but using glossy media with the CP2025dn will cause problems.
The Colour LaserJet CP2025dn is expensive to run, and this is its biggest drawback. The three colour laser toners produce an average page yield of 2800 pages each, while the black toner produces 3500 pages. This is a reasonable figure but once the price of consumables is factored in each page will cost the user an average of 31.5c — an extremely high figure for laser printers. Given that the printer and its consumables are relatively new, expect price cuts soon — but for now this printer is an expensive machine to run.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.
Anthony Grifoni
For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
Steph Mundell
The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.
Andrew Mitsi
The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.
Simon Harriott
My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.

VCY Responds to Porter's Attacks
To say that we do not have very much in common with VCY America or its flagship radio program "Crosstalk" would be something of an understatement:
Crosstalk covers the issues that affect our world, our nation, our families and the Christian church from a perspective centered in the Word of God. Whether we discuss the economy, the political scene, the continuing moral collapse of our nation, legislation that affects the family, or the state of evangelicalism, our authority is found in the unchanging standard of the Holy Scriptures.
But one thing that we do have in common is a concern about Dominon Theology and its increasing prevalence within the Religious Right movement, especially as it pertains to Janet Porter and her sphere of activists.
As we noted earlier, Porter used her WorldNetDaily column to lash out at Discernment Ministries and its blog, Herescope, which was instrumental in covering Porter's May Day rally and its ties to Dominion Theology. This coverage ultimately lead VCY America to sever its ties with Porter's radio program which, in turn, has rendered Porter's organization almost non-existent.
In the wake of this decision, Crosstalk hosted a special program last month with Herescope's Sarah Leslie to expose the dangers of Dominionism ... and today Crosstalk hosted another program with Leslie to respond to Porter's attacks during which both Leslie and host Ingrid Schlueter marveled at Porter's viciousness ... to which I say, "welcome to our world."
I will post a link to the entire program once VCY makes it available on their website (UPDATE: here is the link to the program) but for now I'm going to post two clips that I recorded myself.
In this first clip, Schlueter says that she does not have enough time to debunk all of the lies in Porter's column, but that she, like many others, is horrified by the cultural collapse in this country. But the collapse of our culture is not the result of Christians not caring, but rather Christians (like Porter) who are abandoning the Gospel in favor of false teachers (like Cindy Jacobs) who spread lies and theologies that are not supported by Biblical truth. Leslie then recounts her long history as a Religious Right activist, especially as the head of Iowa Right to Life in the 1980s when she knew Jack Kemp and Pat Robertson on a first name basis and regularly received death threats because of her activism:
In this second clip, Leslie delivers an concise and informative explanation of New Apostolic Reformation/Dominionism/7 Mountains Theology movements where she explains that this is not your typical "get out the vote" type of activism, but rather a concerted effort to literally take over all aspects of our culture so as to bring about the Kingdom of God here on Earth. At the end, Leslie finally says "I don't know how to say it any other way: they're wacky. If you go and look at YouTube, they are barking like dogs and laughing like hyenas":

Joan Rivers, the transgressive comedian, author, Fashion Police commissioner, filmmaker and QVC pitchwoman, died Thursday.
On Aug. 26, the seemingly unstoppable octogenarian was dishing on E!'s Fashion Police about the clothes worn on the red carpet at the Video Music Awards and the Emmy Awards. The next night, she performed her comedy act at a Times Square theater. On Aug. 28, she stopped breathing during outpatient surgery on her vocal cords. Doctors induced a medical coma and put her on life support.
Ms. Rivers died at Mount Sinai Hospital in New York, surrounded by family and close friends.
"My mother's greatest joy in life was to make people laugh," daughter Melissa Rivers said in a statement. "Although that is difficult to do right now, I know her final wish would be that return to laughing soon."

|Bruins confident David Pastrnak can hold up defensively
|01.14.15 at 6:11 pm ET
With David Pastrnak, the Bruins' first line will be able to score goals. The question is how many it will give up.
Given that Pastrnak, though clearly offensively gifted, is the youngest player in the NHL, it's only fair to question how Krejci and Milan Lucic's line will do in the plus-minus department when playing against other teams' top players. The line did not allow a goal in its first game together on Tuesday (really half a game, as they were united midway through the second), but it did score three. Claude Julien will take that any day of the week.
Yet the cautionary tale of the Tyler Seguin Experiment exists, as Pastrnak isn't the first highly talented youngster to see time in the spot that has typically reserved for veteran power forwards (Nathan Horton, Jarome Iginla) over the years.
When Horton was out for the season with a concussion in March of 2012, Julien went for broke offensively by sticking the then-20-year-old Seguin with Lucic and Krejci. They produced at over a goal-per-game clip, but gave up 10 goals before Julien separated them. When the B's were desperate for offense in Game 7 of the first round in 2013, Julien again put Seguin with Krejci and Lucic, only to see them allow goals on their first two shifts.
In case you haven't noticed by now, Julien isn't comfortable with lines that give up more goals than they score (insert then-why-does-he-ever-play-the-fourth-line quip here), so if he plays a trio together, he does so because he thinks it can do more good on the scoreboard than damage.
As such, it was interesting to see that, after the Lightning scored to make it a one-goal game Tuesday night, Julien kept Pastrnak with Krejci and Lucic for the top line's next shift.
Or, put it this way: With the Bruins defending a one-goal lead in a game they had to win against the division leaders, Julien put the youngest player in the league — one whose defense seemed to be one of the things he'd need to improve in order to make the NHL — on the ice against Steven Stamkos and the Bruins lived to tell about it.
"This is not a time to test guys," Julien said Wednesday of his decision to play Pastrnak in such an important spot. "If he was out there, it was because I felt comfortable with him."
Julien said that he considers such decisions with young players to be 'calculated chances.' He noted Pastrnak's improvement getting pucks out along the wall in his defensive zone (Julien makes a good point; Pastrnak had some struggles there in his first five game stint with the B's) and sound decision-making he'd seen from the rookie all night that made him confident that Pastrnak would not be defensive liability in the game's most crucial minutes.
"I think for a player to develop, when you see the right things on certain nights, you've got to allow that player to have an opportunity," he said. "That's how you gain that kind of experience in those situations. Throughout the game, if you've seen situations where he's kind of struggled and had some tough situations come up, you try to keep him away from that. It's up to me to stay on top of the player and the game itself and see whether he's earned it."
Both Krejci and Lucic have given their endorsements to Pastrnak; it would be rather difficult to do given that he's scored four goals over his last two games. Yet while Lucic acknowledged that the trio must stick to the team's system to avoid suffering the same score-a-goal, allow-two-goals fate that they did in the Seguin days, Krejci said that Pastrnak, who hopes to become a strong two-way player like Krejci, will become better and better at applying his defensive learnings as he gains experience.
"It's going to happen that we're going to get scored on, that's for sure, but we have to try to minimize the mistakes," Krejci said. "On the other hand, he knows what to do defensively, but he has just been here a small amount of games and sometimes in a situation, he has to think twice of what do, and in that split second, something can go wrong. It will come with games played and I'm sure he'll be fine."
WILMINGTON — David Pastrnak is just one of the reasons the Bruins are starting to win again. His center being healthy enough to stick in the lineup and perform is among the biggest.
After going in and out of the lineup with lower-body injuries and missing a total of 20 games, Krejci has been back in Boston's lineup for nearly a month. Though he has since hit his stride (nine points in his last eight games) and has established quick chemistry with Pastrnak, Krejci told WEEI.com Wednesday that his injury concerns aren't fully in the rear-view mirror.
"I feel better and better every day," he said. "It is what it is, but yesterday I felt pretty good. As long as there's no setbacks, that's great news."
Asked Wednesday if he's had to do anything to manage the injury since re-entering the lineup on Dec. 17, Krejci said that he's been cautious to make sure what's been his longest healthy stretch of the season doesn't get derailed.
"Yeah, just because this is the [fourth] time coming back," he said. "If it was only the only the first time and I would be fine, I would be like, 'Oh, whatever,' but now I know that I have to stay on top of it. Yeah, it's just because this is the [fourth] time and I don't want to be sidelined again with that. I'm trying to take care of it every day and it's been working."
|Offensively starved Bruins turn to David Pastrnak
|01.06.15 at 2:24 pm ET
The Bruins are ready to continue with the David Pastrnak experiment.
After being recalled from Providence Monday, the Czech 18-year-old rotated with Seth Griffith on the right wing of David Krejci's line and worked with Krejci, Zdeno Chara, Brad Marchand and Torey Krug on Boston's first power play unit. Though it's not known when he will get back into game action, it appears the Bruins are turning to Pastrnak as they desperately seek any sort of offensive presence.
Pastrnak had a goal and six assists for the Czech Republic during the World Juniors. He played Sunday in Providence, and now the Bruins will determine a game plan for when to get him back into Boston's lineup.
"I definitely have to talk to our group here and see how they want him to be utilized," Claude Julien said. "I don't make those decisions by myself. I work with my general manager and we look at the situation. He's come back from the World Juniors. Is he still tired? What's the situation? Do they just want to get him into a few practices before we put him in a game? I haven't had a chance to discuss that with Peter [Chiarelli]."
Pastrnak said he isn't tired from World Juniors, saying he feels ready to resume his NHL career. He was impressive in his five-game stint with the B's earlier this season, getting ample playing with Patrice Bergeron and landing seven shots on goal in Boston's Nov. 28 win over the Jets.
Yet it seems this recall isn't about Bergeron's line, but rather Krejci's. Pastrnak, a right shot right wing, grew up idolizing Krejci, while Krejci has has seen a cast of players — Griffith, Simon Gagne, Loui Eriksson, Craig Cunningham and Reilly Smith — used as his right wing this season.
Though he is young and still very light (he's listed at 165 pounds and probably weighs somewhere around 170), Pastrnak would give the Krejci line the most talented and dynamic right wing its had all season. The 2014 first-round pick leads Providence with 10 goals and 27 points on the season.
Pastrnak downplayed his excitement to potentially skate with Krejci.
"I don't know," Pastrnak said. "I had one practice with David and he's a great player, but everybody here is good and I'd be happy for any minute I'd be on the ice."
If Pastrnak plays five more NHL games this season, the first year of his three-year entry level contract will be burned.
|Team meeting spurs David Krejci, Bruins to pick up slack for Milan Lucic, Patrice Bergeron
|12.30.14 at 8:06 am ET
David Krejci could relate with Patrice Bergeron and Milan Lucic Monday night. He was on the ice while Bergeron and Lucic watched the game with undisclosed injuries from the ninth floor press box.
Earlier in the year, it was up to Bergeron and Lucic to pick up the slack for Krejci and Zdeno Chara when they were out with injuries. This time around it was Krejci and Brad Marchand who led an offensive attack that generated five goals on 45 shots against the Red Wings, and the result was a desperately needed 5-2 win at TD Garden Monday night.
From the first puck-drop, the Bruins were skating hard in all three zones, mucking up the area in front of Detroit goalie Jimmy Howard. Krejci's best move of the night came on the power play in the third period after the Wings had cut the lead to 3-2 after two.
The center skated into the left offensive corner with the puck and gave Seth Griffith enough time to find an open area in a triangle of three penalty-killing Wings. Krejci delivered a short, crisp pass onto Griffith's stick and Griffith snapped off a perfect shot that beat Howard for a 4-2 lead.
"We just shot everything on the net," Krejci said. "We tried to crash the net. That's what happened on the first goal. [Marchand] had a good screen. I thought we had more than 15 shots after the first period. We talk about it, just put the puck on net, create some traffic and don't pass on any shooting opportunities. We did a pretty good job at it."
The big question is why the Bruins, with or without their top players, haven't played like that more often.
"That's a good question, but obviously we are trying," Krejci said. "We kind of talked about a bunch of things [Sunday] and it seems like it worked but like I said before, we did it before and followed up with a bad game. We don't need to have talks like we did before this game and just go out there and realize what you're playing for and we got to get back in the hunt. It was a good game today, but we have to follow up with another one."
|David Krejci thinks Bruins should prioritize first line, too
|12.22.14 at 4:05 pm ET
David Krejci might want to know who his right wing is as much as anyone else.
Claude Julien's hands are tied. Partially because of Krejci's injuries, he waited too long to try Loui Eriksson with Krejci and Milan Lucic. Eriksson has undeniable chemistry with Carl Soderberg and Chris Kelly, but the Bruins haven't given him a chance to develop chemistry with Lucic and Krejci. Given where they currently fall in the standings, the B's might not think they can afford a games-long getting-to-know-you period if the B's don't win games in the process.
So that leaves Krejci, who thought he knew who he'd have for linemates after Jarome Iginla left, with four different right wings (Seth Griffith, Simon Gagne, Craig Cunningham and, ever so briefly, Eriksson) in 14 games this season.
"Everything was – it looked like we were going to play with Loui from the beginning. If not, then someone else, so it was kind of a tough situation," Krejci told WEEI.com Monday. "I was preparing myself the whole summer [as though] I would be playing with Loui. That was on my mind. Then some injuries and those guys play pretty well together right now with Carl and Kells as a line, so yeah."
Added Krejci: "I'm happy that we're winning, but I'd like to be putting some points up as well. That's why I'm here. That's why they re-signed me. It gets a little frustrating at times. You always play with somebody else, but I'm sure we're going to find the right guy. If not, who knows what happens? There's always trades, you know."
On Sunday, Julien finally started Eriksson on Krejci's right wing to open the game. The line had a so-so first period, but allowed a second-period goal and followed it up with a shift that saw Krejci give the puck away and Lucic mishandle the puck at the blue line. Krejci's misplay led to a Sabres scoring chance; Lucic's forced Dougie Hamilton to trip Tyler Ennis in the neutral zone and put the Bruins on the penalty kill.
Julien returned Eriksson to Soderberg's line, with Kelly scoring on the trio's first shift back together. Eriksson scored the game-winner in overtime on a feed from Lucic, but it was during a line change.
While Eriksson with Kelly and Soderberg has been Boston's most consistent line this season, it isn't like any of Boston's forwards are having particularly good seasons. The Bruins are the only team in the league without a nine-goal scorer. They're one of three teams (with the Sabres and Coyotes the other two) who haven't seen a player reach 10 goals.
Part of the Bruins' offensive problem has been that they've only had Krejci for 14 games, leading Julien to mix and match different lines and play Soderberg's line against other team's top forwards and defensemen. Krejci's return allows the Soderberg line to go back to playing against bottom-six players and third-pairing defensemen, which makes their job easier.
In a perfect world, the Bruins shouldn't need Eriksson to win those shifts, as Soderberg is probably a little better than a third-line player, while Kelly has been a solid third-liner for years.
The Bruins value secondary scoring, but having a good first line is more important. The Bruins are better off when Krejci is at his best, and Krejci's at his best when he's comfortable with his linemates rather than taking turns training potential candidates.
So maybe it's Eriksson and maybe it's somebody else, but teams don't miss the playoffs because they don't have great third lines; they do because they don't have first lines. Krejci is eager for Boston's to take shape.
|A closer look at whether Carl Soderberg's line scores too much to be broken up
|12.21.14 at 2:51 pm ET
Claude Julien does not want to separate Loui Eriksson and Carl Soderberg. That much we definitely, definitely know.
On Sunday, Julien reiterated that stance with a quote that got us thinking.
"Right now, the Soderberg line is the only one that's scoring for us," Julien said, "so do you guys want me to break that up and we get no more scoring? So you pick your poison."
Krejci has been in the lineup for 13 games and has had Seth Griffith as his right wing for 12 of them, with Simon Gagne also getting some shifts and Eriksson getting a small taste late in Friday's game. The Bruins might not be 100 percent on Griffith being their first-line right wing, but they won't try Eriksson to see if they have any other internal fits for the job before potentially trading for one.
So, given Julien's quote, we looked at every goal the Bruins have scored when Krejci has been in the lineup. In each game, Soderberg and Eriksson have been together, so it's actually rather easy to tell whether Julien has a point. Keeping in mind that different lines (Krejci's and Patrice Bergeron's) have tougher matchups, here were our findings:
Total goals (13 games): 35
Soderberg line: 9
Krejci line: 8
Bergeron line: 7
Campbell line: 1
Krejci during change with Kelly, Eriksson: 1
The findings aren't overwhelming, but they do illustrate that when the Bruins have their full offensive lineup, the Soderberg line does pretty much all of Boston's secondary scoring (nine of 10 goals). That might be reason enough for Julien to not want to tinker with Kelly – Soderberg – Eriksson.
That said, the Bruins are 22nd in the league with 2.42 goals per game (2.69 with Krejci in the lineup). They need goals, and Eriksson had a four-point game against the Flyers last season when skating with Krejci and Lucic.
Following is a goal-by-goal breakdown, which also takes into consideration that Julien changed half of his lines on Oct. 30 against the Sabres but kept Griffith with Krejci while also keeping Eriksson with Soderberg. Read the rest of this entry »
|5 things we learned as Bruins get David Krejci back and win
|12.17.14 at 10:47 pm ET
On Wednesday, the Bruins got three things Bruins fans thought they might never see again: three goals, a win and David Krejci.
After an up-and-down showing from the B's in Minnesota, Loui Eriksson took a feed from Carl Soderberg and tucked it behind Wild goaltender Niklas Backstrom to give the Bruins a 3-2 overtime win over the Wild (click here for the boxscore). The win was Boston's first in four games.
Krejci returned to the lineup after missing the last 11 games. He had one shot on goal and had a minus-13, even-strength Corsi, which was worst among Bruins forwards.
Krejci played a part in Minnesota's game-tying goal in the third period. A turnover from Krejci in the defensive zone led to a Ryan Suter point shot that Niklas Svedberg stopped with his blocker. Zach Trotman picked up the rebound, but Jason Pominville whacked it away from Trotman and into the net to tie the game at two goals apiece.
That said, Krejci's return is mammoth for the Bruins, who have had their first-line center for just 12 games this season and fell out of a playoff spot without him.
Here are four more things we learned Thursday:
With Krejci returning to the top line, so too did Seth Griffith. The Bruins have played Griffith as their first-line right wing in every game Krejci has played this season, but they have generally used Griffith as a bottom-six player without Krejci.
It's an odd choice on the Bruins' part to not try other players with Krejci and Milan Lucic to determine how many potential in-house candidates the B's have to fill their seemingly up-for-grabs first-line right wing job. The Bruins have still not tried Loui Eriksson with Krejci and Lucic this season.
The lines were as follows:
Lucic – Krejci – Griffith
Marchand – Bergeron – Smith
Kelly – Soderberg – Eriksson
Paille – Campbell – Cunningham

I wish I could give more than 5 stars - this one deserves 10. Lovely crunchy - tasty - easy to make - this was just phenominal - and will now be a staple on my asian cooking nights. Fantastic little morcels....
These were wonderful appetizers. I cut the recipe in half and it made 10 walnut sized balls. I put them in the refrigerator for two hours before frying them as dinner was extended to a later hour. I was worried they would fall apart, but they held together well and were really easy to make! I don't like water chestnuts, and they did not bother me at all in this recipe! I will make these again for sure! Thanks Kate!
Raves reviews from my family. I did have to add a bit more cornstarch. Great flavor.

The present disclosure relates generally to biasing devices used in connection with actuators, and relates more particularly to distributing stiffness within a biasing spring about a longitudinal center axis to reduce non-uniformity in a spring constant thereof.
A great many types of actuator systems are known from diverse technical fields. Actuator systems range from relatively large, slow and imprecise devices, to relatively small, rapidly actuating and highly precise systems such as the type known from fuel injectors and other fluid control systems. In many instances, it is desirable to bias an actuator toward a particular state, such as a predefined position. In the context of fuel injectors, biasing springs are commonly used to bias an actuator or related components toward one of multiple possible positions. For example, return springs are often used in connection with control valves and associated electrical actuators to bias the electrical actuator toward a position corresponding with a particular fluid state of a fuel injector such as a rest state when the fuel injector is not injecting fuel into an engine cylinder. With the ever increasing focus on precision, reliability and predictability in actuator systems, notably fuel injector actuator systems, the behavior of return springs and other biasing devices is increasingly important.
Another common application of biasing devices is providing a preload on certain types of actuators such as piezoelectric actuators. Like other common actuator systems used in fuel injectors, piezoelectric actuators may be activated or deactivated to control the position of a control valve or the like. To enable operation and to ensure accurate, reliable and predictable performance, many piezoelectric actuators are preloaded via a compressive force. Piezoelectric actuators tend to be somewhat sensitive to variations in preload. Moreover, as engine conditions such as temperature change, the dimensions and spacing of piezoelectric actuator components can change. The magnitude of preloading force on piezoelectric actuators used in fuel injectors may be tightly specified for these reasons. As alluded to above, the behavior of return springs and other biasing devices may be important in ensuring desired operation of an actuator. It has been observed that variability in spring construction and design can negatively impact the ability of a biasing spring to perform as desired in certain actuator systems. In the case of piezoelectric actuators, the biasing spring may be used not only as a preloading device, but also as a return spring to return the actuator to a state it normally occupies when de-energized, compounding these issues.
U.S. Pat. No. 7,025,292 to Mohr sets forth one example of a fuel injector having a valve biased via a biasing spring. The spring used in Mohr has the form of a cylindrical sleeve with cut-out regions to impart a spring action to the sleeve. Mohr may have certain applications, but would be considered inferior in others, particularly if applied in certain piezoelectric actuator systems.
A fuel injector includes a fuel injector body, defining a fuel inlet and at least one fuel outlet. A valve having a first valve state and a second valve state is configured to control a flow of a fluid within the fuel injector body via switching between the first valve state and the second valve state. An actuator for the valve is provided which is movable between a first actuator position corresponding to the first valve state and a second actuator position corresponding to the second valve state. The fuel injector further includes a biasing spring including a cylindrical rolled sheet having a first spring end and a second spring end defining a longitudinal center axis, the cylindrical rolled sheet being configured to change in length to bias the actuator toward the first actuator position. The biasing spring further has a helical seam located between the first spring end the second spring end which has a shape adapted to reduce non-uniformity in a spring constant of the cylindrical rolled sheet at least in part by distributing weld stiffness about the longitudinal center axis.
In another aspect, a method of operating an electrical actuator system includes a step of changing an electrical energy state of an electrical actuator of the electrical actuator system, and moving a control element coupled with the electrical actuator against a bias of a biasing spring in response to the step of changing an electrical energy state. The biasing spring includes a cylindrical rolled sheet defining a longitudinal center axis. The method further includes a step of reducing non-uniformity in a spring constant of the cylindrical rolled sheet during the step of moving at least in part by distributing stiffness within the cylindrical rolled sheet about the longitudinal center axis via a helical seam of the cylindrical rolled sheet.
In still another aspect a biasing device for an actuator includes a biasing spring including a cylindrical rolled sheet having a first spring end and a second spring end and defining a longitudinal center axis, the cylindrical rolled sheet being configured to change in length in a direction parallel to the longitudinal center axis to bias the actuator. The cylindrical rolled sheet further has a helical seam located between the first spring end and the second spring end and having a shape adapted to reduce non-uniformity in a spring constant of the biasing spring at least in part by distributing stiffness about the longitudinal center axis of the cylindrical rolled sheet.

Fuel injector 10 may further include a needle check 50 having a first needle check position at which needle check 50 blocks the at least one fuel outlet 16, and a second needle check position at which the needle check 50 does not block the at least one fuel outlet 16. Needle check 50 may include a needle valve member 54 biased towards a closed position via a biasing spring 58 at which it blocks outlet 16. Valve member 54 may further include a control surface 52, which is exposed to a fluid pressure of a control passage 48 defined by injector body 12 and fluidly connecting with passage 46. Fuel injector 10 may further include a control valve assembly 18 which is configured to control operation of needle check 50 by moving between a first control valve state and a second control valve state. Control valve assembly 18 further includes a control valve member 42 which switches between a first control valve position corresponding to the first valve state and a second control valve position corresponding to the second control valve state to control a flow of fluid within fuel injector body 12. A second control valve member 45 may be coupled with control valve member 42. When control valve member 42 is in the first control valve position, control surface 52 may be exposed via control passage 48 to a pressure of high pressure fuel supplied via inlet 14, and when control valve member 42 is in the second control valve position, control surface 52 may be exposed to a low pressure of a low pressure outlet 44 defined by fuel injector body 12.
Fuel injector body 12 may further include an actuator subassembly 21 such as an electrical actuator subassembly coupled with control valve assembly 18. Actuator subassembly 21 may be part of an actuator system 23 and includes a casing 30 having an electrical actuator 32 such as a piezoelectric element that includes a piezoelectric stack 33 positioned therein. Actuator subassembly 21 may further include a biasing spring 20 having a spring body 62, and electrical actuator 32 may be positioned at least partially within biasing spring 20. Actuator subassembly 21 may still further include a control element 24 configured to control the state of another element of fuel injector 10, such as control valve member 42. Control element 24 may include a contact element also identified via reference numeral 24 configured to control the state of a second element of fuel injector 10, such as control valve member 42, via contacting the second element. In other embodiments, control element 24 might control the state of another element of fuel injector 10 without contacting the same, such as by varying a fluid pressure. In one further embodiment, control element 24 might include and be integral with a valve member such as control valve member 42, which in turn controls the state of yet another element such as needle check 50. It is contemplated that contact with another element to control the state thereof, however, will be a practical implementation strategy, and the term "contact element 24" is used hereinafter, but is not intended to be limiting.
Actuator 32 will typically be held in compression via biasing spring 20 and configured to change in length in response to a change in an electrical energy state of actuator 32 to actuate control valve assembly 18. In one embodiment, actuator 32 may be energized from a de-energized state to responsively lengthen and move contact element 24 to contact control valve member 42. Switching actuator 32 between an energized state and a de-energized state can selectively connect control passage 48 with passage 46 or outlet 44 in a known manner via control valve member 42 and second valve member 45. In one embodiment, contact element 24 may be separated from control valve member 42 via a gap 43 defined by contact element 24 and control valve member 42 when actuator 32 is in a de-energized state. Contacting control valve member 42 via contact element 24 moves control valve member 42 between the first and second control valve positions mentioned above. In other embodiments, changing the electrical energy state of actuator 32 could include de-energizing actuator 32 to change a length of actuator 32, adjusting actuator 32 from a low electrical energy state to a higher electrical energy state, etc. In addition, in other embodiments actuator 32 might not be held in compression via biasing spring 20, or might be a different type of actuator. Biasing spring 20 could also act on a different component than on actuator 20, such as on control valve member 42 or on contact element 24. The present disclosure should thus be broadly construed to contemplate a variety of different systems having a variety of different components and component arrangements, where a first component moves to affect the position or state of another component.
Actuator subassembly 21 may further include a flexible diaphragm 28 coupled to move with contact element 24, and an O-ring 26 fluidly sealing between biasing spring 20 and casing 30. As mentioned above, actuator 32 may be a piezoelectric actuator and biasing spring 20 may compress actuator 32 to preload actuator 32. To this end, biasing spring 20 may be in a tensioned state, and energizing actuator 32 may lengthen actuator 32 against a compressive bias of biasing spring 20. Lengthening actuator 32 against a compressive bias of biasing spring 20 may in turn be understood as moving contact element 24 and therefore control valve member 42 against the compressive bias. It will further be appreciated that moving control valve member 42 via contact with contact element 24 can control a fuel injection timing via fuel injector 10. Fuel injector body 12 may further include a threaded preload control nut 36 having a set of external threads 39, for example, for varying the tension on biasing spring 20, and a threaded lock nut 40 to lock biasing spring 20 at a given tension state. Threading nut 36 relatively deeper into biasing spring 20, via engaging threads 39 with a set of internal threads 70 of biasing spring 20 can stretch biasing spring 20 to increase a preload, and vice versa. A preload control element 34, for example, including a thermally expansive or thermally contractive material may be positioned adjacent actuator 32 to expand or contract in response to changes in temperature and thereby maintain or control a preload on actuator 32. The general construction and operating principles of preloading and controlling a preload on an actuator via the use of nuts 36 and 40 and preload control element 34 are described in more detail in co-pending and commonly owned U.S. patent application Ser. No. 12/077,640, filed Mar. 20, 2008.
Turning now to
Segment 68 may be or include a piston configured to translate a motion of actuator 32, and includes contact element 24 located thereon. Segment 66 may include spring body 62 and is configured to generate all or at least a portion of a spring force of biasing spring 20. Spring body 62 may include a first spring end 72 and a second spring end 74. In one embodiment, each of segments 64 and 68 may be welded or joined via any other suitable technique to segment 66 at spring ends 72 and 74, respectively. It should be appreciated that a wide variety of spring configurations, such as multi-functional and uni-functional, are contemplated herein and the illustration in

In one embodiment, spring body 62 may have a right cylindrical shape defining a longitudinal center axis A, and a uniform width in a dimension orthogonal to longitudinal center axis A. Spring body 62 may also include an outer diameter 76 and an inner diameter 78 and a uniform thickness between outer diameter 76 and inner diameter 78. It should be appreciated that in certain embodiments, spring body 62 might be non-uniformly thick, a different shape from a right cylinder or have a non-uniform width. Generally uniform shape characteristics are considered to be a practical implementation strategy, however. Spring body 62 may further include a plurality of voids 88 communicating between inner diameter 78 and outer diameter 76. Voids 88 may be formed in spring body 62, for example via machining or laser cutting, prior to rolling sheet 65 into a cylindrical shape, but might be formed after rolling in other embodiments. If spring body 62 is found to have a higher stiffness than desired, or a non-uniform stiffness, after forming cylindrical rolled sheet 65 into spring body 62, voids 88 may be formed therein to result in the desired characteristics. Voids 88 may have a shape, arrangement, size and number defining in part a spring constant of spring body 62. In one embodiment, voids 88 may all have the same shape such as an ellipsoid shape, a circular shape or an elongate, straight-edged shape having rounded ends as shown, and may be uniformly distributed in spring body 62. In other embodiments, voids 88 might have different shapes from one another or might be non-uniformly distributed. In general, where the number of voids 88 of a given size is greater, spring body 62 may have a relatively lower spring constant and where the number of voids 88 of a given size is lesser, spring body 62 may have a relatively higher spring constant. In one further embodiment, voids 88 may be selectively formed in spring body 62 to tailor the stiffness of spring body 62, for example to increase uniformity of the stiffness longitudinally or radially. Further, voids 88 may also be used to tailor stiffness of spring body 62 to a desired stiffness. In either case, tailoring stiffness to achieve greater uniformity or tailoring stiffness to achieve a desired stiffness, the geometry, including shape or arrangement, of voids 88, their density in spring body 62 or their size or number, may be used to make certain areas of spring body 62 relatively stiffer or relatively less stiff. Voids 88 may be formed prior to rolling sheet 65, after rolling sheet 65, or both.
Peripheral edges 80 and 82 may be joined at a helical weld seam 60 which is located between first spring end 72 and second spring end 74. Although described throughout as weld seam 60, the seam 60 between peripheral edges 80 and 82 may also be formed via any other suitable connection. Weld seam 60 is located in middle segment 66 and is uniquely configured to affect the spring characteristics of spring body 62, as further described herein. In particular, weld seam 60 has a shape adapted to reduce non-uniformity in the spring constant of spring body 62 at least in part by distributing weld stiffness about longitudinal center axis A. Weld seam 60 may have a helical shape, meaning that at least a portion of weld seam 60 defines a helix. It should be appreciated that weld seam 60 need not have a uniform helical angle about longitudinal axis A. In other words, the relative inclination of weld seam 60 relative to a vertical axis corresponding to longitudinal axis A might vary along a length of weld seam 60. For example, weld seam 60 could have a zigzag configuration, or be only partially helical, and still define a helix. Weld seam 60 could also include vertical or horizontal components. In one practical implementation strategy, however, weld seam 60 may have a uniform helical angle from a first helix end 63 to a second helix end 61. Weld seam 60 may also be circumferential of spring body 62 and helix end 63 may be coterminous with spring end 74 whereas helix end 61 may be coterminous with spring end 72. In one practical implementation strategy, weld seam 60 may have a radial path about longitudinal center axis A which is an integer multiple of 360�, and may be substantially equal to 360�.
As mentioned above, weld seam 60 may be configured to reduce non-uniformity in the spring constant of spring body 62. In one embodiment, weld seam 60 may reduce radial non-uniformity in the spring constant at least in part by distributing stiffness radially about spring body 62. Spring body 62 may, within weld seam 60 and in regions adjacent weld seam 60, be relatively stiffer than in other regions such as regions adjacent voids 88. It has been discovered that where a spring such as spring body 62 includes relatively stiffer portions and relatively less stiff portions, the spring may behave unreliably, unpredictably and/or non-uniformly. As mentioned above, in the case of certain actuator systems such as piezoelectric actuator systems, non-uniformity in spring behavior can negatively impact performance of a system, for example by reducing the accuracy of fuel injection timing. Weld seam 60 tends to impart a relatively greater stiffness to portions of spring body 62 than a stiffness associated with other portions of spring body 62, such as those adjacent voids 88. Voids 88 may therefore define a first stiffness coefficient of spring body 62, whereas weld seam 60 may define a second, greater stiffness coefficient of spring body 62. By forming weld seam 60 as described herein, the relatively greater stiffness associated therewith can be distributed radially about spring body 62. In one practical implementation strategy, voids 88 are offset from weld seam 60 and do not intersect weld seam 60, although designs wherein one or more voids are intersected by weld seam 60 may still fall within the scope of the present disclosure. For instance, voids might be formed in spring body 62 which intersect weld seam 60 to decrease stiffness or to increase uniformity in the spring constant of spring body 62. In certain earlier springs formed from a rolled sheet, weld seams were formed longitudinally and therefore oriented generally parallel a longitudinal center axis of the associated spring. This approach tends to concentrate material having a relatively greater stiffness, i.e. the weld, in a limited radial area of the spring. When a load is applied to a spring of such a design, the spring tends to expand or contract more in less stiff radial segments than in relatively more stiff radial segments, due to radial non-uniformity in a spring constant of the spring.
The present disclosure utilizes a different approach where, rather than concentrating stiffness, the stiffness associated with weld seam 60 is distributed radially about spring body 62. In one practical implementation strategy, any given radial segment of spring body 62 will tend to have a spring constant substantially equal to any other radial segment. In addition to radial uniformity, linear uniformity in spring behavior may also be improved. Those skilled in the art will appreciate that as a conventional spring is compressed or expanded, the force required to impart additional compression or expansion tends to increase, according to the spring constant. For certain actuator systems, such as fuel injector systems, it may be desirable to utilize springs where the change in the force required to further compress or expand a spring is relatively linear in a service range for the particular spring. Earlier springs having relatively stiff sections in certain radial segments, such as a longitudinal weld seam, tended to throw off the linearity sought in the spring behavior, in addition to behaving radially non-uniformly.
Referring to the drawings generally, a fuel, such as diesel fuel, may be supplied at a relatively high pressure to inlet 14, and thenceforth to passage 46. High pressure fuel may flow from passage 46 into control passage 48 to apply a high pressure to closing hydraulic surface 52, holding needle valve member 54 in a closed position and blocking outlet 16. As discussed above, biasing spring 20 may be exerting a compressive bias on actuator 32. When initiation of a fuel injection event is desired, actuator 32 may be energized. As a result, actuator 32 will tend to lengthen, moving contact element 24 across gap 43 to contact valve member 42, and moving valve member 42 down in the
During changing length of spring body 62 via energizing and de-energizing actuator 32, spring body 62 will tend to behave more reliably and predictably than in earlier designs not having a weld seam 60 configured as described herein. This is contemplated to provide for improved performance in operation of the overall system of which actuator 32 is a part. It should further be appreciated that when actuator 32 is de-energized, the preloading force exerted via spring 20 on actuator 32 will tend to be more uniform and predictable than that possible or at least practicable with certain other spring designs. Greater uniformity in spring constant is thus contemplated to provide for improved performance during operation of an actuator system, and also greater ease in setting an accurate preload on a piezoelectric element prior to placing it in service. Those skilled in the art will further appreciate that many recent advances in engine operating strategies rely upon the injection of highly precise quantities of fuel, at a highly precise timing. While piezoelectric actuators have shown much promise of application to fuel systems to achieve these and other goals, the relative sensitivity of piezoelectric actuators to inaccurate preloading have in some cases prevented their use in engine systems where they might otherwise be advantageously used. The relatively greater uniformity in spring constant available via the present disclosure is contemplated to enable the use of piezoelectric actuators in some instances, and with certain desirable spring types such as those disclosed herein, where their use would otherwise not be available.
The present description is for illustrative purposes only, and should not be construed to narrow the breadth of the present disclosure in any way. Thus, those skilled in the art will appreciate that various modifications might be made to the presently disclosed embodiments without departing from the full and fair scope and spirit of the present disclosure. Other aspects, features and advantages will be apparent upon an examination of the attached drawings and appended claims.

Konrad Peterson/Konrāds Pētersons (1888-1981) was a Latvian-born revolutionary, socialist and civil engineer who lived for most of his life in his adopted home of Ireland.
At the age of only 17, he participated in the Russian Revolution of 1905. Forced to flee to Dublin in its aftermath, he was active in socialist and Irish Republican politics in Dublin during his time living in the city from 1906 to 1919. Returning home to a newly declared independent Latvia, he was witness to the Nazi and Russian invasions of his home city during the Second World War. He returned to Ireland in the mid-1940s to work with Bord na Móna and lived in Athy, County Kildare where he died in his 90s.
Peterson's story is a fascinating one that has largely been forgotten. Especially in labour history and republican circles in Dublin. Sandra Bondarevska within the Latvian community and local Athy historian Frank Taaffe has done much to help ensure his memory hasn't been totally neglected.
Note: his first name is sometimes spelt 'Conrad' and his surname 'Petersen'. For the purpose of continuity, I will spell it as Konrad Peterson which is the most commonly used form and the spelling which is on his grave.
Early life (1888-1905):
Peterson was born in Riga in the Russian Empire (now Latvia) on 15th October 1888. He studied at Tilo (Tilava) primary school and then at the Mangali Maritime school from which he was expelled for refusing to speak only Russian.
According to nekropole.info, his father ran a tavern in the suburb of Zasulauks outside Riga city.
Sandra Bondarevska in an unpublished history article states that Konrad had been been a member of Revolutionary movement in Latvia from a young age and had "had close ties with the famous social democrat and renowned poet Rainis, who had emigrated to Switzerland with his wife Aspazija after the events of 1905."
During the 1905 Russian Revolution, it is believed that Konrad participated in two major events in Riga. The first was the 10,000 strong workers demonstration on 13th January in protest at the Bloody Sunday massacre. Three days earlier in St Petersburg, Russia, over 1,000 unarmed demonstrators were shot dead by soldiers of the Imperial Guard as they marched towards the Winter Palace to present a petition to Tsar Nicholas II of Russia.
In September 1905, Peterson was involved in the daring raid of Riga Central prison which involved the rescue of two imprisoned comrades. His involvement is in the revolutionary movement is covered in Fēlikss Cielēns memoir 'Laikmetu main̦ā'.
John Langins (History of Science professor, University of Toronto) met Peterson in later life and retold in his memoirs how:
Conrad took part in the bloody demonstration in January. Jumping over the wall, one Kazaks tried to spear him (in the) the bottom but (the) spear (went through his) thick coat out the back.. (Konrad was) later was an active combatant in Riga and in the countryside. These revolutionary instincts remained with Conrad (his whole) lifetime.
In wake of the brutal repression following the revolution, Peterson was smuggled out of Riga in December in a cargo ship and traveled to Ireland via Scotland where he had family.
Langins memoirs elaborates how:
Konrad fled from the terror of the Tsar. (He) hid (in a) ship that traveled to Scotland with a few comrades. Some were concealed (amongst) potatoes and some Linos. Those (in) potatoes (were) found, and right there on the ship (were) shot, but those who had Linos, was moved to one (friendly) small cabin, where they spent several days and nights in meetings, motionless on one bed … When (they) jumped down from the board in Scotland, they almost could not walk and was accepted as heroes of the English trade unions.
Dublin (1906-1919):
Arriving in Dublin about 1906, he moved in with his uncle Charles Peterson, of the well-known pipe firm Kapp & Peterson, who lived on Leinster Road, Rathmines.
He was enrolled at Padraig Pearse's famous school St. Enda's in Rathfarnham. In the year 1908-1909, he is listed as being a pupil in Fourth Class, Division II.
Peterson would have been about 20 years of age in 1908 (!) but as he had only been in Ireland for two years, with presumably little or no English, it makes sense that he would be in a class for much younger children.
His english much have improved greatly as on 3rd May 1910, he is listed as taking part in a debate between the Irish Women's Franchise League and the Socialist Party of Ireland. The resolution was "That an adult Suffragist should support a Bill immediately enfranchising women on the same terms of men". Speaking in favour were Mrs. Cousins, Mrs. Bac, Miss B. Bannister and Mr. Pike of The Nation newspaper. Speaking against were Mr. Ryan Loughran and 'Konrad Petersen'. Presumably both were representing the Socialist Party of Ireland.
Whether Peterson actually believed in that viewpoint or was speaking against for argument's sake is unknown.
In the 1911 census, the Peterson family were living at 114 Leinster Road, Rathmines, Dublin 6. Konrad, aged 21, was listed as a scholar. He listed his religion as a "Free Thinker" as did his uncles Charles (60) and John (45), both pipe-makers. Charle's wife was a Dublin-born Catholic called Annie Peterson (nee Forde).
The Peterson family home was just a few minutes walk from 'Surrey House' at 49b Leinster Road, Rathmines. This was the home of Constance Markievicz and a hotbed of revolutionary activity. Markievicz became friendly with Konrad and his uncle Charles.
Around this time, he enrolled as a Engineering student at the Royal College of Science for Ireland (RCScI). This college later absorbed into University College Dublin (UCD) as the faculty of Science and Engineering.
Peterson continued his activity with the Socialist Party of Ireland and the milleu surround it. In 1911 he offered his advice and help to Irish Republicans organising protests against the visit of King George V and Queen Mary to Dublin. In her Witness Statement (No. 909) to the Bureau of Military History, Sidney Czira (aka 'John Brennan') recalled:
It was suggested to us by Conrad Peterson who was a student in the College of Science and who had some experience of shock tactics in Czarist Russia – he was from Riga – that we should adopt the methods used by demonstrators in Russia i.e. fold all the leaflets in two and catching them by the corner, fling them into air if we saw the police approaching. They would fan about the crowd and be picked up.
Sidney Czira (nee Gifford) was an officer of Cumann na mBan in Dublin and sister of Grace Gifford, the widow of Joseph M. Plunkett who was executed after the Rising.
He was certainly active in labour politics in Dublin in 1913 but it is not known to what extent he participated in the turbulent events of the Lockout.
In this wonderful picture from around 1913 published in Fearghal McGarry's book 'The Abbey Rebels of 1916: A Lost Revolution' you can see Konrad Peterson, Constance Markievicz, Helena Molony, Michael O'Gorman and George Doran dressed in costume for a performance or fancy dress party.
C.S. Andrews wrote that during this time Peterson:
formed close links with many of the literary and theatrical figures of Dublin … including, in particular, the famous Daisy Bannard and the man who she afterwards married, the Republican journalist Fred Cogley ('Man of No Property, p. 188).
Peterson graduated in 1913 with an Engineering degree from the College of Scienc . Afterwards, as retold in CS Andrew's book 'Man of No Property' (p. 188), he worked on a number of engineering projects. These included a survey, carried out by a group of private entrepreneurs before the First World War, into the possibility of harnessing the Shannon for Electricity Production. The project came to nothing and the idea remained dormant until revived by Dr. TA. McLaughlin in the 1920s.
On May 4th 1915, he was granted naturalisation by the British government. He was listed as 'Konrad Peterson, from Russia. Resident in Rathmines, Co. Dublin'.
Around this time he married Helen Yeates from Dublin. From the process of elimination, I believe this is our Helen Yeates, born 9th February 1893 to Joseph and Bridget Yeates living at 10 Beresford Place. By 1911, eighteen-year old Helen was living at 107.1 Amiens Street.
Peterson was living and working in Dublin during the 1916 Easter Rising and was friends with many of its leading personalities including Connolly and Marchievicz. According to The Irish Press (24 May 1951), Peterson "helped in the organisation of communications for the Rising". But there is no more reliable sources or references to back up claims he took an active part during Easter Week.
Many will know the story of the Finn and Swede who fought in the GPO making references to Russian and British imperialism. Interestingly, there is also some evidence to suggest that a handful of Russian revolutionaries may have visited Dublin in the immediate aftermath of the Rising.
In February 1918, Peterson was present at large meeting that took place at the Mansion House to celebrate the Russian Revolution. The Irish Times (9th February 1918), reported that those present wished "to congratulate the Russian people on the triumph they have won for democratic principles". During the proceedings, "The Red Flag" was sung and red and republican flags were waved.
The Irish Independent (5th February 1918) wrote:
Mr. Conrad Peterson who announced himself as a Russian Social Democrat spoke strongly in support of "the great struggle for peace, liberty and bread".
Those present also included Cathal O'Shannon, Dr. Kathleen Lynn, Countess Marchievicz and Mrs. (Maud) Gonne-McBride.
In June 1919, Peterson was listed as a committee member of the 'James Connolly Birthday Celebration' in the Mansion House. Tickets were one shilling and all proceeds were to be devoted to the establishment of a 'Connolly Memorial Worker's College'.

FLOWERY BRANCH, Ga. -- Atlanta Falcons offensive line coach Mike Tice didn't expect rookie first-round pick Jake Matthews to be perfect in his first NFL game at left tackle.
He wasn't.
Matthews got whistled for a false start and a hold in the first quarter of Saturday's 24-17 exhibition loss to Tennessee. Then in the second quarter, he was beat on an inside move that led to Matt Ryan getting sacked.
"He jumped the guy, and he brought his feet together," Tice said of Matthews. "He got out of balance. He rushed it."
The line, as a whole, protected Matt Ryan well, which pleased Tice. But the run blocking wasn't up to par, and Matthews contributed to those woes.
"He had a couple of brain farts out there thinking," Tice said. "He had some growing pains, some learning things. He had a couple mistakes. He had a mental and, obviously, he gave up a sack.
"He didn't struggle, but he had more bad plays than he had on the right side. And he's in there for three practices. We figured that it wasn't going to be smooth sailing, especially against a couple of good players."
Tice sees no reason to panic, however.
"He'll be better [today]," Tice said. "And he'll be better in the game this week, if we play him. And we'll go from there."
Everything seemed so simple for Matthews as he dominated at right tackle throughout training camp. Seeing him stonewall guys in practice became a regular occurrence. He even performed well against Houston pass-rush demon J.J. Watt in joint practices against the Texans.
"I thought the first time through, J.J. got him," Tice said. "I thought the second time through, it was a tie. And I thought in the team stuff, I thought Jake fared very well. So that's a good thing. You want to go against the best players."
Then starting left tackle Sam Baker goes down with a season-ending knee injury in the game against the Texans, immediately forcing Matthews to the left side. Although he played left tackle last year at Texas A&M, even Matthews admitted it would take some time to readjust.
The biggest thing Tice rode Matthews about at right tackle was improving his right hand. That's no longer the case.
"His right hand got fixed when he moved to the left side," Tice said. "I told him, 'If I knew that was going to be fixed when I moved you to the left side, I would have moved you sooner.' He said, `I would never do that to Sam Baker.'"
"His hands are better on the left side, much better than on the right side. He probably has more confidence."
Now, it''s just a matter of Matthews getting into a left tackle routine.
"He's been in a right-hand stance since April or whenever the hell I got him -- May," Tice said. "He's done everything at right tackle since the first week. He didn't miss a snap with the ones. He's probably got the most plays of any lineman on our team in the offseason and in training camp. And then all of sudden, poof, you're a left tackle. It's going take a little bit of time.
"He'll get all that cleaned up. It's just going to take a little time. It's not going to happen by Jacksonville, either. We don't expect it to."
How Matthews progresses as a run blocker might be the aspect worth monitoring the most moving forward.
"Like many young players [who] are coming into this league from a passing program, he's got a long way to go with his run blocking," Tice said. "When he played for Mike Sherman, he was in a pro-style offense. So he's done it all before. Then [Texas A&M] came in with the new staff and went to the passing stuff and the two-point stance. He's just got to continue to work on it and feel comfortable in his stance."
