Abstract—Free space optical (FSO) communication offers the advantages of compact terminals and very high data rates without using scarce radio frequency spectrum. Unfortunately cloud and fog, together with scintillation caused by small temperature variations in the atmosphere, can result in significant attenuation and highly variable amplitude fluctuations that degrade link availability. This paper describes a 2 Mbit/s FSO modem and codec design, that includes a suitably large interleaver and strong channel coding scheme using a low density parity check (LDPC) code, plus synchronisation algorithms, to provide reliable communication over a 12 km optical channel.
I. I NTRODUCTION Free space optical (FSO) communication systems have been used for both terrestrial [2] and space applications [3] for decades. Advantages include high bandwidth, no RF licensing issues, smaller equipment size and weight, low probability of detection/intercept and immunity from interference or jamming. Except for intersatellite link applications, FSO systems are usually degraded by various forms of atmospheric attenuation and fading. Traditionally, FSO links have made relatively poor use of strong channel coding techniques that may be employed to overcome the effects of fading. Commercially available FSO links for terrestrial applications normally operate over short distances up to several kms. Recently there has been additional interest in the use of iterative coding for FSO communications, e.g. [5], [6], [7], but there are relatively few descriptions of practical implementations of FSO codecs using modern channel codes. In addition, similarly to the use of iterative decoding in radio frequency communications, we find that the lower signal to noise ratios used in these systems makes the synchronisation task more difficult and there is almost no literature describing suitable algorithms for FSO communication systems. In this paper we present an initial design and implementation of an FSO transceiver operating at information rate rb of 2 Mbit/s. A half rate (R = 1 ) low density parity check (LDPC) 2 code has been used with binary pulse position modulation (BPPM), thereby giving a pulse rate on the channel of 8

Mpulses/s. This design uses an interleaver that is large enough to ensure that each codeword contains representative samples of the fading distribution. This allows standard LDPC codes to be employed and suits applications where the extra latency from the interleaver is not an issue. An alternative strategy, for delay constrained applications, requires the use of custom codes designed for block fading channels, e.g. [9]. This paper is organised as follows. The next section describes the system model and design of the FSO modem and codec. This includes some specific issues related to the assumed fading distributions and channel state estimation, with supporting simulation results. Section III presents brief details of the real-time system implementation and loopback testing on the bench using recorded or synthesised channels. Section IV provides examples of field testing over a 12 km FSO link. Conclusions are presented in Section V. II. FSO T RANSCEIVER D ESIGN A. System Model In common with most FSO communication systems, this project uses a Direct Detection approach, with InGaAs photodiodes operating at the "eye safe" wavelength of 1550 nm. Given the modest data rates employed we decided to use BPPM rather than on off keying (OOK) as the extra processing can be readily implemented in commercially available hardware and this modulation choice provides improved BER and synchronisation performance compared to OOK. The particular aim of this design is to provide reliable transmission under the fading channels typically encountered in FSO links. Atmospheric scintillation is the rapid (up to 1kHz) variation in received signal that arises as the laser beam propagates through small-scale fluctuations in air density related to temperature gradients. A wide range of fading distributions have been investigated for FSO links including log normal, exponential and gamma-gamma, e.g. [1]. The most appropriate channel model and its parameter values depends on a wide range of factors including the length of the link, receive aperture size and environmental conditions. For the purposes of simulation and testing the transceiver under consideration, based on previous measurements [10] we have adopted log normal fading distributions with the

from PD and transimpedance amplifier to HDLC codec, PRBS calc and MAC interfaces
where I(t) is the received irradiance at time t. Apart from the fading distribution, temporal correlation of the channel is a key system parameter. Typical coherence times for FSO channels are several milliseconds and tend to increase as the receive aperture size increases due to the greater spatial averaging (e.g. [10]). As mentioned in Section I, in this design we interleave many codewords over a period much longer than the channel coherence time, in an attempt to provide a range of faded and unfaded receive symbols in each codeword. This approximates drawing the fading sample for each symbol from an uncorrelated ergodic distribution. We selected a 32 msec interleaving period as a compromise solution which does not introduce excessive latency. At the receiver the photodetection process gives a signal whose amplitude is proportional to the received optical power, unlike RF receivers! The wanted signal is degraded by a combination of channel fading and various types of noise. The latter is a combination of optical background variation, noise from the photodetection process and additive electrical noise. It is common to model the overall effect as an additive Gaussian distributed noise term, which is uncorrelated between samples. Our own measurements support this assumption, [11]. Given the above, we may therefore represent each BPPM slot sample at the receiver, following matched filtering and assuming ideal symbol timing, as y = f x + w where f is the optical fading channel amplitude, x is the transmitted PPM pulse amplitude, without loss of generality equal to 0 or 1, and 2 w is zero-mean Gaussian noise with variance σw . In BPPM the bits are transmitted as a pair of pulses, i.e. either (0,1) or (1,0), so the appropriate symbol metric, from the log likelihood ratio, is easily shown to be Λ= f (y1 − y2 ) , 2 σw

and preamplifiers but avoids the need for analog variable-gain amplifiers. C. Synchronisation Symbol timing recovery (STR) involves estimating pulse positions relative to the free running sampling clock and also resolving the ambiguity of which pair of pulses belong to each FSO symbol. The former requirement is addressed by using a feed forward timing algorithm, [8]. This approach avoids the "hang-up" problems that would occur in a fading channel if feedback loops were employed. The latter requirement is easily determined, after decimating the sample rate to one sample per pulse, by measuring the mean difference in adjacent pulse amplitudes. This metric is continuously updated for each of the two possible symbol timings; the larger value indicates which pair of pulses arise from one BPPM symbol. "Decoding" of the PPM symbol then corresponds to simply taking the difference between this pair of samples. These samples are also processed to estimate the symbol variance and then used to control the AGC system. Following these operations, frame synchronisation can be achieved. We have used a large unique word (UW) of 128 bits with a correlator to locate framing. When frame synchronisation has been determined, given the offsets in clock frequency between transmitter and receiver, we provide a unique word window that allows UW detections to drift a small amount that depends on clock accuracy. The UW correlator is also used to make measurements of the raw bit error rate. This approach has the advantage of working well at low SNRs without use of decision directed methods. D. LDPC Coding For this initial design we used a regular LDPC code with variable node degree dv = 3 and check node degree dc = 6 leading to a code rate R = 1/2. In order to reduce the memory requirements and to allow for a semi-parallel decoding architecture we constructed the LDPC code following the approach in [14]. This construction is based on a base matrix with the required degree distribution where every zero is replaced by a zero matrix and every non-zero entry is replaced by a cyclic shift matrix with a random cyclic shift. The base matrix is therefore expanded by the size of the cyclic shift matrix. For this particular implementation, we used a base matrix with 64 columns and 32 rows and a cyclic shift matrix of length 32 which allows to process 32 check nodes in parallel. The
where yi is the i−th slot sample. In the case of ideal channel state information (CSI) at the receiver, f is known for each symbol, plus the noise variance, and hence the optimum LLR may be delivered to the decoder. In practice this optimum scaling may be hard to achieve. B. Receive Processing Overview In this paper we will concentrate on the receive operations. Figure 1 shows a summary of signal processing steps involved. The input signal is oversampled with 8 samples per rectangular PPM pulse, then match filtered. A 14 bit ADC followed by a slow automatic gain control (AGC) scheme in the discrete-time domain is employed in this receiver. "Slow" means that the receiver does not attempt to follow rapid channel variations; this issue is discussed below. The current approach can accomodate a range of signal amplitudes from different photodetectors

resulting overall code is of length N = 64 · 32 = 2048 with M = 32 · 32 = 1024 parity-check equations. Details of an efficient pre-computation of this parity-check matrix can be found in [15]. Our implementation uses the min-sum algorithm (MSA) to simplify the operations in the check node decoder and all messages in the decoding algorithm are quantised with 8 bit. E. Simulation Results We performed bit error rate simulations of the chosen code to compare the performance of the optimal sum-product and the implemented min-sum algorithm. Furthermore, we compared the influence of the availability of channel state information (CSI) at the decoder, i.e., whether the decoder knows the optical fading channel amplitude f . These results are shown in Figure 2 for the AWGN channel and the fading channel with independent, log normal distributed fading coefficients and scintillation index SI = 1. The maximum number of iterations has been set to 100 and all computations have been carried out with double precision floating point (our implementation uses an 8 bit quantisation of the messages). The best results are obtained with the sum-product algorithm and full CSI at the receiver which serves as a reference. However, the bit error rate of the min-sum algorithm without CSI is only approximately 2dB worse compared to this reference. The comparison with the AWGN channel shows the strong impact of channel fading on the bit error rate performance of the system. III. M ODEM I MPLEMENTATION AND L OOPBACK T ESTING A. FPGA Platform and Interfaces A commercial FPGA board, plus data acquisition daughter board, was used in the FSO transceiver (see Figure 3). Each
board implements a transmitter and receiver to provide a bidirectional FSO link. This board contains a Stratix 3 FPGA, with approximately 20% of the logic resources used to implement the transceiver. The 32 msec interleaver is stored in RAM within the FPGA. Apart from displays and various switches, the hardware also contains a Gbit Ethernet chip that provides data interfaces. For debugging and optimisation, this interface is used to deliver UDP status packets that capture values of key transceiver parameters such as number of errors and synchronisation metrics, at regular intervals. When no data packets are received over the Ethernet interface, the transmitter sends fill packets over the link. Alternatively the firmware includes a pseudo random binary sequence (PRBS) test option which is useful for BER testing. B. Loopback Test Results Field trials of this equipment over a real FSO link were invaluable and are described in the next section. However channel conditions can vary significantly over a few hours and don't allow evaluations to be repeated under controlled conditions. We therefore found it useful to implement a loopback test facility on the bench. Initially the transceiver was found to perform well with AWGN and random on-off fading channels. The receiver could tolerate channel outages of up to almost 10 msecs with no decoder errors. This erasure rate, approaching one third, is obviously below the theoretical maximum of 0.43 for this code, but still seems an excellent result in practice. In later loopback tests we have used a fading channel with the fading provided by a digital to analog conversion system using recorded channel samples or synthetic fading channels. A high speed analog multiplier is used to impose the fading on the transmit signal. In addition to the fading channel, baseband noise can be added at the receiver input. Attenuations in each of the fading signal and noise paths allow any SNR ratio to be tested. This testing regime proved to be significantly more difficult to achieve performance that approached simulated results, mainly due to the impact of the fading channel and

the large dynamic range of the signals involved, and hence required some optimisation of synchronisation parameters and LLR scaling. In the sample test results discussed below, we illustrate performance in AWGN and fading loopback channels. For the latter, we synthesised a fading LN channel at a 5kHz sample rate with σI = 1 and channel coherence time of 10 msecs. SNR is the measured electrical signal power at the receiver input relative to the measured noise power. We examined symbol timing estimates and found that although the raw estimates from the feed forward algorithm mentioned earlier can give large variations during fades, after filtering the final timing jitter is usually small. Figure 4 illustrates the maximum number of consecutive UW misses in each 1 second observational interval between UDP status packets, together with SNR measurements over the test period. Since UW detection does not benefit from interleaving and deinterleaving operations, in a fading channel it is easy to lose many frame detections in a row. However this aspect of the processing is quite robust since even at the lowest SNR shown in the figure, the number of UW misses is less than our threshold value (80) and frame synchronisation is solid. Figure 5 shows the raw and decoder output error rates for an AWGN channel and the LN fading test condition just outlined. Given the large dynamic range of the fading channel, it was difficult to obtain a large enough SNR to measure very small raw error rates. In the AWGN channel, the decoder performed very well and matched the simulated performance. In the fading channel the performance is some dBs behind the simulated results, most likely due to a combination of synchronisation imperfections, quantisation and LLR scaling, plus limited interleaver size. This is confirmed by measurement results using a perfectly interleaved channel which are also shown in Figure 5. In this case, the decoding threshold

is close to the simulation results. In both cases, the decoder still exhibits a steep waterfall region, above which no decoder errors were recorded. The channel coding provides a large SNR improvement at low bit error rates compared to the uncoded performance. IV. F IELD T RIALS OVER 12 KM FSO L INK A. FSO Test Range A 12 km range has been established from the Mt Lofty Ranges to the SPRI Building at Mawson Lakes. The primary aim of this facility is to allow FSO and extremely high frequency (EHF) channel statistics to be recorded over a wide range of meteorological conditions to provide realistic models for FSO and hybrid FSO/RF communication systems. The profile of the range can be seen in Figure 6; further details can be found in [11] and [12]. The FSO transmitter consists of a 1550 nm seed laser, erbium doped fibre amplifier with maximum power output of 100 mW and collimator. The transmit beamwidth is approximately half a milliradian. Two receivers have been employed; in the experiment described below a 150mm diameter Fresnel lens was used with an InGaAs photodetector and transimpedance amplifier. B. Initial Test Results The FSO transceiver was tested during August and early September over our 12 km test range under a variety of

atmospheric and weather conditions. Given the time of year the scintillation index varied from close to 0 up to about 2. (We expect significantly higher scintillation during Summer months.) During tests of the 2 Mbit/s transceiver we inserted an acoustic optic modulator in the transmitter optical fibre chain, driven from the FSO encoder with a PRBS source. After early adjustment of receiver firmware parameters the system worked very well under clear sky conditions, with no decoding errors over several hour periods. In order to test the transceiver performance under more difficult conditions, reduced aperture sizes were employed and a number of tests were conducted during poor weather. In the former category, with 100mW transmit power, we found that the decoder started to fail when the receiving area of the Fresnel lens was reduced to approximately 10 square cms. During bad weather tests, each 5 minutes we captured optical images of the view from the SPRI building towards the transmit site, plus radar images each 10 minutes. Figure 7 illustrates several modem parameters over a period of approximately 6 minutes. During this time a large low-altitude rain cloud progressively encroached on our link from slightly before 10AM, causing very high attenuation and complete signal loss for approximately 5 minutes after the period shown. A meteorological radar image from 10AM, covering the FSO link, is shown in Figure 8. This corresponds to a rain rate over the FSO link of approximately 5 mm/hour, [13]. The raw error can be seen to increase steadily as the mean channel amplitude falls to very small values. Finally the decoder starts to fail (i.e. LDPC decoding does not converge reliably). (Both error rates are plotted on logarithmic scales, from approximately 10−4 to 0.5.) At around this time the number of consecutive UW misses increases, reaching the threshold at which frame synchronisation is lost. V. C ONCLUSION This paper has outlined the architectural design, implementation, simulation and testing of a 2 Mbit/s transceiver designed specifically for free space optical channels. Strong
channel coding operating over a large interleaver, plus robust synchronisation approaches, have verified that tens of dB gain can be achieved compared to an uncoded system. The interim results presented in this paper show significant gains over uncoded systems but illustrate that achieving the full potential of channel coding in heavily fading FSO channels is challenging. We have demonstrated that robust communication is possible with the current firmware over longer FSO channels than usually employed. However the performance gap between interleaved and non-interleaved channels shows that there's considerable scope for further gain under severe fading. As usual in the realisation of novel wireless transmission systems, particularly over fading channels, this project has raised a number of interesting issues that we hope to address in further work. These include the most appropriate channel state estimation methods and quantisation options for FSO systems; code design, both for ergodic and block fading channels; plus modem and codec architectures suitable for significantly higher data rates.

Real-Time Systems: Design Principles for Distributed Embedded Applications / Edition 2by Hermann Kopetz
View All Available Formats & Editions
Pub. Date: 04/26/2011
Publisher: Springer US
Real-Time Systems: Design Principles for Distributed Embedded Applications focuses on hard real-time systems, which are computing systems that must meet their temporal specification in all anticipated load and fault scenarios. The book stresses the system aspects of distributed real-time applications, treating the issues of real-time, distribution and fault-tolerance from an integral point of view. A unique cross-fertilization of ideas and concepts between the academic and industrial worlds has led to the inclusion of many insightful examples from industry to explain the fundamental scientific concepts in a real-world setting. Thus, this book serves as an excellent text for advanced level courses on real-time systems.
Real-Time Systems: Design Principles for Distributed Embedded Applications also serves as an invaluable reference for professionals in industry. The book explains the relevance of the latest scientific insights to the solution of everyday problems in the design and implementation of distributed and embedded real-time systems. Thus, as a reference source the book presents state-of-the-art real-time technology in a coherent, concise and understandable manner. Because the cost-effectiveness of a particular method is of major concern in an industrial setting, design decisions are examined from an economic viewpoint. The recent appearance of cost-effective powerful system chips has tremendous influence on the architecture and economics of future distributed system solutions. The composability of an architecture, i.e., the capability to build dependable large systems out of pre-tested components with minimal integration effort, is one of thegreat challenges for designers of the next generation of real-time systems. The topic of composability is thus a recurring theme throughout the book.
Real-Time Systems: Design Principles for Distributed Embedded Applications is essential reading for anyone involved in the field of real-time systems.

Focus is on key learning areas
To the editor:Gov. Matt Blunt recently celebrated "Back to school" throughout the state with students from preschool to college. His visit in Cape Girardeau focused on elementary students in a technology classroom at Jefferson Elementary School.
Data show that Missouri fourth-graders have made gains in math since the early 1990s but rank in the bottom third nationally. Yet about a quarter of all new business formations in Missouri are related to math-engineering-technology-science-based industries.
The importance of METS to the future well-being of Missouri was emphasized at the governor's METS summit last year (www.missourimets.com).
The METS Alliance has created a strategic plan addressing this issue with five major goals: improve the performance of all students, expand the pool of students motivated to pursue METS careers, expand the pool of METS educators, establish a technology plan to support METS curricula, increase public awareness of the value of METS knowledge and METS-related jobs.
Since taking office, the governor has secured more than half a billion dollars in new funding for Missouri students and classrooms. In addition, he signed a higher education bill that increases funding for higher education, provides tuition stabilization and increases needs-based scholarship funding from $27.5 million to $72.5 million.
Blunt's commitment to education will ensure that students will be better prepared for the future. His recent "Back to school" visits motivate students about math and science and increase public awareness for families and communities about the importance of METS learning for our future economy and quality of life.

You know the tagline—you don't get to 500 million friends without making a few enemies. Mark Zuckerberg might have made a mighty foe indeed out of Google, after his company reportedly hired a public relations firm to spread negative stories about Google's privacy record. At least, that's what The Daily Beast is reporting.
According to the site, PR firm Burson-Marsteller "offered to help an influential blogger write a Google-bashing op-ed, which it promised it could place in outlets like The Washington Post, Politico, and The Huffington Post." The blogger turned around and posted the firm's e-mails publicly, revealing the smear campaign's existence but not its ultimate source. The identity of the company who retained Burson's services remained under wraps.
Well, The Daily Beast now claims a Facebook spokesman confirmed that his company was the one who hired Burson. The spokesman even volunteered an explanation:
First, because it believes Google is doing some things in social networking that raise privacy concerns; second, and perhaps more important, because Facebook resents Google's attempts to use Facebook data in its own social-networking service.
Judging by the allegedly leaked Burson e-mails, the privacy smear campaign centered on Google's Social Circle feature. Bloggers weren't the only ones targeted, either. USA Today reported yesterday that it, too, had been contacted by Burson about the story.

Virtual Bridges, Inc. today announced the hires of two new executives including Jack Angelo, vice president of worldwide services, and Todd Middlebrook, vice president of product management, expanding the company's leadership team.
Angelo brings more than 20 years of experience in global services to Virtual Bridges, serving most recently as the vice president of network systems services at International Game Technologies. In this new role, he will oversee all services and support for Virtual Bridges' award-winning cloud desktop and virtualization solutions. Previously Angelo served as vice president of enterprise solutions and services for United Devices and vice president of enterprise systems support for Dell's server division.
A seasoned technology veteran, Middlebrook has spent more than 17 years bringing successful enterprise products to market. At Virtual Bridges, he will be responsible for global product management and development of Virtual Bridges' products, helping enterprises and managed service providers simplify desktop management and provisioning, improve security and compliance, and address cost containment initiatives. Previously, Middlebrook spent nearly 10 years leading multiple customer advocacy and technology management teams at Microsoft. He also held roles at IBM Tivoli as well as start-up, TorchQuest Inc.
"Jack and Todd are strong team players with great track records of success in their previous roles. They bring not only a deep understanding of their respective jobs, but also the real hands-on experience to drive measurable results," said Sam Cece, CEO of Virtual Bridges. "Easy to use, affordable desktop virtualization solutions are in high demand. Expanding the team with top talent like this assures that we can not only keep pace with our rapid growth trajectory, but lead the way in bringing new products to market."
Virtual Bridges fills a void in the market for managed service providers and other enterprises that want to share VDI infrastructure across multiple customers while retaining control from a central location. The company's all-in-one solution eliminates the need for additional software, network and hardware costs, and offers on-premises, hosted service or hybrid delivery models.

LOS ANGELES — The Portland Trail Blazers moved to 49-27 on the season and 22-18 on the road with a 124-112 victory versus the Los Angeles Lakers in front of 18,110 at Staples Center Tuesday night.
"Probably more than anything else I liked our defense in the third quarter," said Trail Blazers head coach Terry Stotts. "We got our hands on a lot of balls, we were very active. They made a lot of shots in the first half, a lot of jump shots but I thought our activity defensively was really important, got us playing in transition a little bit."
With the victory, Portland remains two games ahead of of Golden State for fifth and are just one and a half games behind Houston for fourth in the Western Conference standings. The Trail Blazers have now had six winning streaks of at least four games or more this season for the first time since the 1999-2000 campaign.
The game was close for the first two quarters, with Portland holding a 29-27 lead after the first 12 minutes of play despite shooting 35 percent from the field. The Trail Blazers improved 10 percentage points from the field in the second quarter, but Lakers guard Nick Young shot even better. The freewheeling guard out of USC who goes by the nickname "Swaggy P" went 7 of 8 from the field for 18 points while playing all 12 minutes in the second.
"I just got in the zone," said Young, who finished with 40 of L.A.'s 112 points. "I got out there and played my hardest and we still keep fighting."
But while the Lakers were forced to rely on Young to do most of their scoring, the Trail Blazers had both Aldridge and Damian Lillard to carry the load. Portland's All-Star duo combined to score 23 points on 7 of 12 shooting while going a perfect 9 of 9 from the free throw line to largely negate Young's performance and take a 63-61 lead into the intermission.
"It was a two-point game at halftime because (Young) got it going," said Stotts. "He kept them in the game."
Portland would take control in the third quarter by holding the Lakers to 28 percent shooting and Young to six points.
"Second half I thought we guarded better," said Aldridge. "We tried to take away tendencies, we tried to give up less easy shots. I felt like Nick Young had a lot of easy shots in the first half. He's a good scorer so he's going to score, but I think we did a better job of making his shots harder."
Along with doing a better job defensively, the fluid ball movement that has been integral in Portland's success recently but was missing in the first half Tuesday night returned in the third quarter.
"At halftime I brought it up again about just moving the ball," said Aldridge. "I felt like guys thought they had great one-on-one game but I was like, with this team, if you move the ball we'll go from having a really good shot to a really great shot. So I thought guys listened to that and I thought guys made great reads in the second half."
That ball movement would continue in the fourth quarter, with the Trail Blazers going on a 19-6 run midway through the final quarter to take a 23-point lead, their largest of the night. Portland would score just once in the final three minutes, but had more than enough of a margin to coast to a 12-point victory.
"In the first half they made a lot of midrange shots," said Stotts. "They didn't have a lot of points in the paint, they made a lot of their midrange and I think that kind of came back to us in the second half."
"I knew it was a big game for us," said Lillard. "Coming in, some said it could be a trap game with a team not in the playoff race. We knew coming in that they were a dangerous team, since they came to our place and shocked us, so I just wanted to come out aggressive, and do whatever it took to help the team a win. A lot of guys put their best foot forward, and we were able to do it."
Lillard also added eight assists, three steals, two rebounds and a monster dunk in the nationally-televised game on TNT.
"I came off the pick-and-roll and I seen Pau (Gasol) standing straight up," said Lillard of the dunk. "I exploded around him and I saw him get off balance a little bit and then I just rose up. I knew that he would be trying to play catchup and he had already blocked one of my shots because I had kind of like tried to lay it up, so I just wanted to go punch one. Just go try to finish strong and I was able to get through there."
With Tuesday night's performance, Lillard joins Stephen Curry, Kevin Durant and LeBron James as the NBA's only players with at least 1,600 points and 400 assists this year.
Aldridge shot 12 of 20 from the field and 7 of 8 from the free throw line to finish with 31 points while pulling down 15 rebounds and handing out 6 assists in 33 minutes. He's the first Trail Blazer since Clyde Drexler in 1990 to have Trail Blazer with at least 30 points, 15 rebounds and 6 assists in a single game.
"You try to get a little bit low to take the contact and then as soon as he hits you he turns the other way and shoots it way high and fades away," said Lakers center Chris Kaman of guarding Aldridge. "It's just hard to get to. He is an exceptional shooter. Just one of those players that are unique and have a special gift that not a lot of players have."
With their performances Tuesday night, Aldridge and Lillard are n0w the first Trail Blazers teammates since Rasheed Wallace and Bonzi Wells in 2002 to score at least 30 points in the same game.
"LA was great on the block and Damian made shots — he was aggressive going to the basket," said Stotts. "But I thought it was a lot of the other things. Defensively, Damian was very active throughout the whole game, got his hands on a lot of balls, got us out in transition. LaMarcus, he and Robin together were very good defensively in protecting the paint. The other thing Damian did on LA's postups, he was setting some screens, occupying people and I thought that allowed for good spacing for LA's postups."
Robin Lopez, playing on his 25ht birthday, got yet another double-double with 10 points and 10 rebounds in 34 minutes. Nicolas Batum finished with 16 points, seven assists, five rebounds and two steals in 35 minutes. Wesley Matthews struggled through a 4 of 12 night shooting to finish with 10 points, though he also added six assists and four rebounds.
Next up, the Trail Blazers get two days off before hosting the Suns at the Moda Center in a game with significant playoffs implications. Tipoff is scheduled for 7 PM.
It's summer time in Portland (or at least, it's supposed to be), which means there's no lack of street fairs, farmers markets, beerfests and art walks to attend. Anyone who frequents such events knows how hard it can be to get from Point A to Point B when there's thousands of people in between.
But Damian Lillard has you covered. In a new adidas short entitled "Creating Clutch," the 6-3 point guard out of Weber State traverses a busy street market in China (wearing the "PDX Carpet" colorway of the D Lillard 2, if I'm not mistaken) using an array of moves that you can incorporate into your own crowd-surfing…
In "Creating Clutch," Portland Trail Blazers star Damian Lillard shows us there is no such thing as downtime if you want to be one of the best clutch players in the NBA. A crowded street market in China during his recent Summer tour became his court, the ultimate opportunity to test his creativity and put his skills to the test.
The spot is one of three released by adidas as a part of the "Here To Create" series, which includes football players chasing rabbits through the Everglades and some kind of soccer/motocross amalgam.
With Portland's foray into free agency now complete, Joe Freeman, he of The Oregonian/OregonLive.com, and I, Casey Holdahl of ForwardCenter.net/TrailBlazers.com, hit the Moda Center studio to record another edition of the Rip City Report podcast, which you can listen to below…
In this almost all Twitter-submitted questions edition, we discuss the signings of Evan Turner, Festus Ezeli and Meyers Leonard, the decision to match the offer the Brooklyn Nets extended to Allen Crabbe, how the additions and returns could change lineups going forward and the notion that the Trail Blazers need to make a trade. There's also some hot Pokemon Go and "Keeping Up With the Kardashians" talk to start the show, so you might want prepare yourself to fast-forward through the first few minutes.
You can find the Rip City Report on Soundcloud, iTunes and Stitcher. And a reminder that the offseason is a great time to leave a review on iTunes!
UPDATE: The team has officially announced that they have matched the Nets' offer sheet to Allen Crabbe, though a "formal announcement" and Crabbe actually signing the contract will not occur until later in the week.
After finishing up their pursuit of new free agents, the Trail Blazers have wasted little time in turning their attention to the free agents on their own roster. After reportedly signing restricted free agent power forward Meyers Leonard to a four-year deal, the Trail Blazers, according to Adrian Wojnarowski of The Vertical, have matched the four-year, $75 million offer sheet the Brooklyn Nets tendered to third-year guard/forward Allen Crabbe, ensuring that the former Cal Bear will be back in Portland next season…
The Portland Trail Blazers have matched Allen Crabbe's four-year, $75M offer sheet with Brooklyn, league source tells @TheVertical.
— Adrian Wojnarowski (@WojVerticalNBA) July 10, 2016
Nets bid on Crabbe has been thwarted — and Crabbe returns to Blazers on four-year, $75M contract. Now, Nets wait on Tyler Johnson sheet.
— Adrian Wojnarowski (@WojVerticalNBA) July 10, 2016
The message out of Portland ownership and management is clear: Blazers trying to win this year and beyond — loading up on this roster.
— Adrian Wojnarowski (@WojVerticalNBA) July 10, 2016
As is often the case when it comes to restricted free agents, the Nets offer to Crabbe, who has averaged 7.0 points, 2.0 rebounds and 1.0 assists per game through three season, was considerably larger than many assumed the 6-6 wing would receive in an effort to discourage the Trail Blazers from matching. And after the Trail Blazers signed free agent guard/forward Evan Turner to a four-year deal, some assumed that combined with the size of the Nets offer might result in Trail Blazers letting Crabbe walk.
But that would not be the case. Crabbe has been a favorite of the front office and coaching staff since the team acquired former Pac-12 Player of the Year via trade with the Cleveland Cavaliers during the 2012 Draft. And though he played sparingly in his first two seasons, he saw his minutes increase dramatically in 2015-16, as he appeared in 81 games and responded with averages of 10.8 points on 44 percent shooting and 39 percent shooting from three, 2.7 rebounds and 1.2 assists while serving as one of the team's best perimeter defenders.
There were rumors that outside of the money and years, Crabbe, who has typically come off the bench for the Trail Blazers, was intrigued by the opportunity to start and play a larger role with the Nets. But for his part, Crabbe seemed more than satisfied that he would be returning to Portland…
— Allen Crabbe (@allencrabbe) July 10, 2016
With Crabbe now signed, forward Maurice Harkless is the last Blazer still available on the free agent market. Like Crabbe, Harkless is a restricted free agent, which gives the Trail Blazers the right to match any offer he receives from another team. It is also possible for the Trail Blazers to sign Harkless even if he doesn't receive an offer sheet from another team, as they have reportedly did Sunday with restricted free agent power forward Meyers Leonard.

Incipio MacBook Pro Selvage Denim Sleeve
Despite rumors that new MacBooks may be coming as soon as WWDC, it seems Incipio has decided to take a calculated risk with the release of its Selvage Denim Sleeve ($50) for the 13" and 15" MacBook Pro. The company is likely hoping that if Apple does update its laptop line, the new models will still fit inside. As you might've guessed from the name, this sleeve is made from the same stuff as your jeans, and it has some nice aesthetic and functional design choices that make it worth considering.
Complementing the denim exterior is a soft, black inner lining to keep your computer scratch-free. A rose gold zipper runs across the top to keep everything secure; it's a pretty standard feature, but we do like that Incipio chose a cool hue for it. In addition, a small pocket on the front is included suitable for a notepad, pen, or a few cables.

Jack and Dinos Chapman's latest installation is currently on view in Hong Kong. The work is comprised of four dioramas depicting historical events with miniature figures. Violence, holocaust, and death pervade the work, as well as commercial images of characters from McDonald's. This creates a landscape rife with gritty humor and heavy irony. This work evokes a level of discomfort that is shockingly arresting. Jake says, "It's as pessimistic as we can make it but it's pessimistic in a joyful sense. Fatalistic in a joyful sense. There's nothing foreboding about this. It doesn't serve any kind of moral end…We take McDonald's as being a marker of the transformation from industrialisation to the end of the world. McDonald's once represented the idealism of fast food and the space rest era. Now it's consistent with the dilation of the ozone and a litigious clown who's lost his sense of humour.'" Check out other posts we've done about these artist brothers here.
Lost Planet's Psychedelic Website
My friend over at Champagne Valentine recently designed this out-there website for Lost Planet studio. Not your typical web 2.0 approach, the result is instead a more abstract, intuitive and interactive experience. Is this the future of the net? Will the days of Twitter icons and blogs be gone, replaced by ethereally floating moon-orbs surrounded by hands? In their own words, the site "is an experimental online video channel and porfolio showcase for the Lost Planet editing studio. The site is an otherworldly portal into the psyche of Lost Planet where visitors can explore a porfolio of work via a bizarre planetary interface. "

Nicholas Nyland's Colorful Abstractions
Nicholas Nyland is a Washington-based artist who creates paintings, sculptures and installations. Stating that his work is "driven by a fascination with the life of form, the nature of creation and the will to decorate," Nyland makes works that are abstract, but contain references to history and traditional craft sources. Embracing abstraction because as he says, "it is generous and capacious, able to absorb and then release a multitude of references," Nyland does in fact draw from a myriad of sources. For his most recent solo show in Seattle, Physical Speculations on a Future State, Nyland incorporated inspiration from Chinese scholar's stones, Japanese gardens, Early American decorative traditions and 1970s design. Despite such wide-ranging influences, Nyland manages to create works that are at once formally engaging and conceptually inquisitive. Nyland leaves room for a viewer to consider material, gesture and form, but enigmatic historical references also provide inquiry into the way we define and identify objects.
There is lightheartedness to Nyland's work that borders on humorous. A viewer can tell that Nyland enjoyed making whatever object she is observing. The lack of seriousness involved in Nyland's works further promotes active questioning about material, influence and formal choice. Moreover, the tactile quality of Nyland's work makes it all the more engaging. Bordering on craft with some of his works, Nyland's pieces are all distinctly handmade. There is a purposeful clumsiness to them that is charming and endearing.
Recent winner of a Contemporary Northwest Art Award, Nyland's work will be on view at the Portland Art Museum through January 12, 2014.

MoMA Launches New Björk Video And An Expansive Retrospective Of Her Musical Career Thus Far
In a daring undertaking, MoMA's curator Klaus Biesenbach has pulled together an immersive exhibition concentrating on the last twenty years of Björk's musical career, her eight full length albums and also features the launch of her new video Black Lake. Taken from her new album Vulnicura (2015), and filmed in Iceland in the summer of 2014, the 11 minute long video uncharacteristically explores the personal life of Björk and her break up with long time romantic partner Matthew Barney. The video was commissioned by the gallery and gave Björk another chance to work creatively with director Andrew Thomas Huang, whom she teamed up with on her previous video Mutual Core. For Black Lake, she also worked with the talented Erna Ómarsdóttir – a choreographer who gave life to Björk's emotional journey through the break up. The video moves through the different stages of separation, including grieving, processing, and reincarnation.
The exhibition also features a retrospective of her music videos, from Debut (1993) to Biophilia (2011) across from the screening of Black Lake. In the lobby of the gallery, there is a showcase of the instruments used on Biophilia: a gameleste, a pipe organ, gravity harp and a Tesla coil. And to compete the experience,
…Songlines presents an interactive, location-based audio experience through Björk's albums, with a biographical narrative that is both personal and poetic, written by the acclaimed Icelandic writer Sjón, along with many visuals, objects, and costumes, including the robots designed by Chris Cunningham for the "All Is Full of Love" music video, Marjan Pejoski's Swan Dress (2001), and Iris van Herpen's Biophilia tour dress (2013), among many others.

Rivane Neuenschwander Turns Beautiful Ideas Into Installations
Rivane Neuenschwander is a Brazillian artist who works in film, photography, sculpture, collaboration, participatory events and installation. Her work employs beautiful ideas, unpretentious materials and an inspiring vision. For I Wish Your Wish, an installation at the New Museum, Neuenschwander drew from a tradition at the São Salvador church Nosso Senhor do Bonfirm. She invited visitors to take a ribbon from the installation, tie it around their wrist, and leave it until it falls off. Once that happens their wish will come true. Or First Love, a work where a police sketch artist sits with visitors as they describe their "first loves." The portraits were then hung in the gallery for the exhibition. Rain Rains, is a collection of leaking buckets controlled from flooding by a Sisyphean recirculation tended to by museum staff. One Thousand and One Nights is a collection of galaxy scenes that depict narrative layers of which the viewer becomes a participant. The hole-punched circles along with the frames, articulate the duration of the exhibition in calendar form. A viewer is encouraged to contemplate the idea of one thousand and one nights.
Allowing the participation of visitors, Neuenschwander blurs the boundaries that traditionally stand between artist and viewer. She instigates an idea, permitting it to discriminate via the public. Her work becomes a living, breathing mass collaboration combining nature, language and the ephemeral.

Some pages on Drupal use more memory than other pages. I think it's a waste of server resources to reserve 64M or more to all pages in Drupal only because the modules' page (or a section with graphics) reaches this peak and I want to avoid white pages when doing changes.
So, my question is: Is it a good practice to manage different memory limits programmatically, depending of the section or page? Some pages use 32M or less, so I think it's better to optimize specific sections of a web app with specific limits.
I've read a lot about optimization practices but I haven't found handling memory limits dynamically or a Drupal module dealing this kind of matter or applying this approach.
