C++ pointer to member of derived class. <p>I don't understand what's happening here. I have a class <code>Base</code> that contains a field <code>a</code>. Now I create a <code>Derived</code> class that extend Base. I also have a template function that prints the field we want by passing a pointer-to-member template argument. </p>
<pre class="lang-cpp prettyprint-override"><code>#include <iostream>
class Base {
public:
Base(double a):a{a} {}
double a;
};
class Derived : public Base {
public:
Derived(double a) : Base(a) {}
};
template<double (Derived::*p)>
void print(Derived d) {
std::cout << d.*p;
}
int main() {
Derived d {10.0};
print<&Derived::a>(d);
}
</code></pre>
<p>The problem is that it doesn't work, but if I only use the base class:</p>
<pre class="lang-cpp prettyprint-override"><code>template<double (Base::*p)>
void print(Base b) {
std::cout << b.*p;
}
int main() {
Base b {10.0};
print<&Base::a>(b);
}
</code></pre>
<p>It works as expected and prints <code>10.0</code>. How can I get it to work with the subclass?</p>
<p>The compiler says:</p>
<pre><code>test.cpp:15:6: note: template argument deduction/substitution failed:
test.cpp:21:23: error: could not convert template argument ‘&Base::a’ from ‘double Base::*’ to ‘double Derived::*’
print<&Derived::a>(d);
</code></pre>

What kind of QoS do I need?. <p>I have a small office. There are ~5 PCs connected via cable. There is 1 PC via WiFi, 3 VoIP phones and a bunch of cellphones connected via WiFi.</p>
<p>There is a Gigalan switch and a internet connection via a modem and router. The internet connection is 10 MB for download and 1MB for upload.</p>
<p>When an user is download a big file from the internet, all the others users cannot browse or cannot place calls. Or the calls have a big latency that makes them very low quality.</p>
<p>How do I diagnose where is the problem? A better switch would make things better? Or is it a problem with my router?</p>
<p>I can run a few tests using a linux box and come back with the results.</p>
<p><strong>UPDATE:</strong></p>
<p>My hardware configuration (all home equipment, nothing fancy):</p>
<ul>
<li>1 gigalan switch</li>
<li>1 cable modem (provided by my carrier)</li>
<li>1 linksys router with public ip</li>
<li>1 wifi access point (professional) connected to the switch.</li>
<li>3 voip phones directly connected to the switch (no wifi here). each one to different ports on the switch.</li>
<li>~5 PCs via ethernet and 1 via wifi.</li>
<li>I haven't set up any qos in the router or specific configuration.</li>

Angular 2 injector hierarchy and NgModule. <p>I wonder how <code>NgModule</code> actually affects Angular 2 injector hierarchy.</p>
<p>What does the hierarchy look like in an app with nested modules? Does it create a new injector instance per each module or gets access to top-level injector (similarly to Angular 1.x modules)?</p>
<p>It can be somewhat confusing to figure out the tree in a big app.</p>
<p>Is there a way to print out, inspect or explore visually the hierarchy of injectors (like it could be done for scope hierarchy in Angular 1.x)?</p>

How to use spot instance with amazon elastic beanstalk?. <p>I have one infra that use amazon elastic beanstalk to deploy my application.
I need to scale my app adding some spot instances that EB do not support.</p>
<p>So I create a second autoscaling from a launch configuration with spot instances.
The autoscaling use the same load balancer created by beanstalk.</p>
<p>To up instances with the last version of my app, I copy the user data from the original launch configuration (created with beanstalk) to the launch configuration with spot instances (created by me).</p>
<p>This work fine, but:</p>

Socket connection into Docker initially succeeds then fails. <p>Running under MacOS I am connecting from a node.js app with net.Socket() into a Docker container running on the same host, which contains a C++ sockets server under Centos. The Docker run command is:</p>
<pre><code>docker run -it --rm -p 14000-14010:14000-14010 -v /Users/me/Development/spdz:/spdz spdz/spdzdev
</code></pre>
<p>When the c++ server in docker is <strong>not</strong> running, I see a successful connection in node followed 3ms later by a socket closed message.</p>
<p>It appears as if a proxy in front of the container is accepting the request, passing it through to Docker where it is rejected. However this leads to erroneous messages in my front end application which thinks the connection was successful, only to find out later it was not.</p>
<p>I would like to see a simple connection declined. Any suggestions as to how this may be remedied or better understood would be helpful. </p>
<p>I am confident that the behaviour is introduced by Docker, as running the components outside Docker gives the expected immediate failure on connection. Also I have tried mapping the exported ports to an external network interface rather than localhost but see the same behaviour.</p>

`xmodmap` not working on startup. <p>I recently installed Debian 9 and inserted my usual <code>~/.Xmodmap</code> file and added <code>xmodmap ~/.Xmodmap</code> to my <code>.xsession</code>. To my disappointment this didn't actually work. </p>
<p>For reference, I run <code>i3</code> from <code>startx</code> without a DM.</p>
<p>To test if the command ran successfully I replaced the command in my <code>.xsession</code> with <code>touch ~/prior && xmodmap ~/.Xmodmap && touch ~/post</code>. And the files were in fact created indicating that the <code>xmodmap</code> command was indeed ran correctly but the mappings were reset somewhere, probably by a call to <code>setxkbmap</code>. </p>

n-bucket water puzzle. <p>Inspired by this <a href="https://math.stackexchange.com/questions/324594/three-bucket-water-puzzle">post</a>. I am thinking of a general case.</p>
<p><a href="https://mathoverflow.net/questions/5800/generalization-of-the-two-bucket-puzzle">Reference</a> to read.</p>
<p>Suppose $N,L_1,L_2,p,q$ are integers, and $N L_1 = pq$. with $p\ge 2$ and $L_1>L_2$.</p>
<p>Now you have $N+1$ buckets, the first $N$ buckets are full of water, each of these buckets can hold $L_1$ liters of water, the left one is a small bucket which is empty at first, the small bucket can hold $L_2$ liters of water.</p>
<p>Now the problem is I want to split the $N L_1$ liters of water to $p$ people evenly, everybody can get $q$ liters of water.</p>
<p><strong>Question: in what situation $(L_1,L_2,N,p,q)$ we can split the water evenly, in what case we cannot.</strong></p>
<hr>
<p>For $p=1$ case, that means all the water will go to one people, that is easy.</p>
<p>For the original problem setting, if we change the capacity of the small bucket, let $(L_1,L_2,N,p,q)=(8,L_2,2,4,4)$, we can see that </p>
<ol>
<li>when $L_2 = 1$, it is easy to do, we just get $1$ liter of water every time.</li>
<li>when $L_2 = 2$, it also easy, we just get $2$ liters of water every time.</li>
<li>$L_2 =3$ is done in the post.</li>
<li>$L_2=4$ is also easy as the first two.</li>
<li>I can prove when $L_2 = 6,7$, we cannot succeed.</li>
</ol>
<p>I guess, if $L_2>q$, then we cannot succeed. I am trying to cook up a theory on this, but very limited. Since to find out a proper way to split is kind of NP hard.</p>
<p><strong>Conjecture 1</strong>:
$gcd(L_1,L_2)\mid q$ and $L_2\le q$ are necessary(not sufficient) to find a solution.</p>

custom key sequence in ubuntu mate. <p>I've been looking at custom key shortcuts on Ubuntu, but I haven't seen anything regarding custom key sequence in Ubuntu Mate 16.04.1.LTS:
Ideally, when I press:</p>
<p><em>the windows key + enter,</em> </p>
<p>this would trigger, in sequence:</p>
<p><em>alt+right, control-v, alt-left</em></p>
<p>Is this possible? If it's then possible to tweak the timing between these 3 combos, that'd be amazing, but likely unnecessary. I don't know how lofty my dreams can be in Ubuntu Mate...</p>

Frequent crashing on BrettSpielWelt? Solution inside.... I was playing Dominion on BSW (www.brettspielwelt.de) with some friends last night and some of the players were having the game lock up on them every few minutes. You can re-join the game just by restarting the client so it's not a HUGE disaster, but it certainly slowed the game down a lot. Sometimes it would crash twice in the same player's turn!
Anyway, I did some digging afterward to see if there's a fix. Apparently the issue is caused by the JVM running out of memory from all the pretty high-resolution graphics, and due to the sandboxed-ness of Java it can't easily request more after the app has been launched. Resizing the window to make it bigger than the default exacerbates the issue, since a bigger window means more pixels means more memory taken up on graphics. You could just leave the window at the default size, but that's no fun, so here's
-----
**THE FIX**
* First, if you haven't already, download the standalone client. It's exactly the as the web-based client, but it installs on your computer so you don't have to load the .jar file from BSW every time. Downloads are [here](http://www.brettspielwelt.de/Community/Download/).
* If you just installed the client, run it once so it can download all the game data.
* Next, create a shortcut. For the Target field, put:
"C:\Program Files\Java\jre6\bin\javaw.exe" -cp "." -Xms64m -Xmx256m de.brettspielwelt.client.Starter
The above assumes java is installed in "C:\Program Files\Java", so if you put it somewhere else, adjust accordingly.
* For Vista or Windows 7, change the Start in field to:
%APPDATA%\Roaming\BSW
On XP it's:
%APPDATA%\BSW
This is where the updater stores the actual program data.
-----
Basically what this shortcut does is sets the initial Java heap size to 64MB (-Xms64m) and the maximum Java heap size to 256MB (-Xmx256m). You can increase it further, to say -Xmx512m if you still get crashes, though it's more likely that something else besides running out of memory is causing them at that point. Without these options, the default maximum heap size is 64MB, which is downright puny by modern standards, and you can see how that could cause problems.
Edit: The same fix should work for the OSX and Linux clients as well, just create a shell script using this template:
`cd` *path\_to\_installed\_app\_data*
`java -cp . -Xms64m -Xmx256m de.brettspielwelt.client.Starter` | 0non-cybersec

Would having 4 states per "bit" rather than 2 mean twice the storage space?. <p>Pretty straightforward fundamental, albeit naive, question:</p>
<p>Would having 4 states per "bit" rather than 2 mean twice the storage space? In case that isn't clear, I mean as in if every "storage structure", rather than only representing 2 values, (base 2 : 0, 1), could represent 4 values (base 4 : 0, 1, 2, 3).</p>

HDD activity when computer is idle. <p>What can cause HDD activity when computer is left idle? My HDD is quite loud and I want to get rid of the noise when computer is idle.</p>
<p>It happens on Windows 7, automatic defragmentation and antivirus background scanning are turned off. Recently noticed it happen also while running Windows 10 TP install (which is installed on another drive - SSD, but the activity is still on HDD). I've looked into Resource manager - "Processes with Disk Activity" and found only system processes there, <strong>svchost.exe</strong> mainly - does it mean, it's some service causing this HDD activity? How do I found out which one?</p>
<p>UPDATE:</p>
<p>Based on PID I've found out which svchost process is causing it. <img src="https://i.stack.imgur.com/4kXLz.png" alt="enter image description here"></p>

Beamer/TikZ shadow printed via Adobe Reader (PostScript) cause errors. <p>Consider the example below compiled using <code>pdflatex</code>. Basically it is a simple test of the Frankfurt theme and the Whale color theme (just attempting to make something smaller).</p>
<p>We experience problems with this example when printed on our Konica Minolta C360.</p>
<p>When we print from Adobe Reader, on Linux (or Mac, or from Windows using a PostScript Driver), the print is ignored. Prints fine if printed on Canon, HP or Oki, also print fine if we do not use Adobe Reader!</p>
<p>AR also prints on the KM, if the file is made using <code>latex+dvips+ps2pdf</code>.</p>
<p>I'm having some discussions with KM as to what the problem is.</p>
<p>Here are a few interesting observations.</p>
<p>If I print the PDF to a PS file on Linux using AR 8, the Adobe Distiller 9 on Win7, complain and recreate a PDF that is flawed.</p>
<p>AR X on Win 7, freezes if I attempt to print the PDF to a file.</p>
<p>The main problem in the PDF is the shadow, there is no problem if I remove the shadow.</p>
<p>Does anyone know if there are Adobe problems in regards to some of the shadings used by TikZ? (when compiling with <code>pdflatex</code>)</p>
<p>I can provide some of the generated files if needed.</p>
<p>I use an up to date TL 11 system to create the offending PDF.</p>

It was found in a commit released by a malicious user by changing the owner of the orphaned AUR package and including a malicious <code>curl</code> command.</p>
<p>The <code>curl</code> command will download the main bash script <code>x</code> then the second script <code>u</code> (<code>u.sh</code>) in order to create a systemd service and using a function to collect some system data (non sensitive data) but the scripts can be modified by the attacker to be uploaded sequentially.</p>
<p>In practice not all users have the ability to check the PKGBUILD before building any package on their systems for some reasons (require some knowledge , take more time etc...).

<p>I want to create my nginx config so that:</p>
<ol>
<li><a href="http://en.example.com" rel="nofollow noreferrer">http://en.example.com</a>$request_uri => <a href="https://en.example.com" rel="nofollow noreferrer">https://en.example.com</a>$request_uri</li>

How to power down display on terminal?. <p>I would like to power down/up my display from the terminal.</p>
<p>Right now I have:</p>
<pre><code>setterm --blank force
#wake
setterm --blank poke
</code></pre>
<p>Which gives a blank screen; but active screen (screen still receives output from computer, just blank output, it won't enter a "no signal" state)</p>
<p>How would I turn off the display completely like you can do from X with this?</p>

Live Time in Windows 8. <p>There is an app in Windows Store called "The Time" which shows current time (every minute) on its Tile. The app can do this without registering any Background Task.</p>
<p>How can it do this?</p>
<p><strong>UPDATE:</strong> it seems that it schedules lots and lots of tiles!
Because if you draw back the computer time, it will stop working.
However, I don't know how many tiles it schedules and how many tiles it is possible to schedule?</p>

What's the difference between the "remainder" and "radius of convergence" for Taylor series that converge for all $x$?. <p>From what I can understand, the remainder is how much difference there is between the function itself and the polynomial approximation. And the radius of convergence is related to the series representation of the polynomial approximation, and how its convergence could be tested by the ratio test.</p>
<p>But what's the difference between them when they seem to tell you the same thing?</p>
<p>For example, since <span class="math-container">$\sin(x)$</span> is <span class="math-container">$$ \sum_{n=0}^\infty(-1)^n \frac{x^{2n+1}}{(2n+1)!}, $$</span> it seems that we can find that it converges for all values of <span class="math-container">$x$</span> by either</p>
<ol>
<li>making to the remainder becomes zero (by having it approach <span class="math-container">$0$</span> by having <span class="math-container">$n$</span> approach <span class="math-container">$\infty$</span>.</li>
<li>showing that the ratio test has convergence criteria</li>
</ol>
<p>My other example would be <span class="math-container">$e^x$</span>, but that seems easier to do the ratio test on since the <span class="math-container">$f^{(n+1)}(c)$</span> term isn't bounded.</p>
<p>It seems that doing the ratio test for <span class="math-container">$\sin(x)$</span> will give me the same result as making the remainder <span class="math-container">$0$</span>, and finding that the remainder is <span class="math-container">$0$</span> for <span class="math-container">$e^x$</span> is the same result as the ratio test.</p>

Best event based architecture for Linux to GUI. <p>I've looked around <a href="https://www.quora.com/What-are-the-most-popular-online-forums-or-chatrooms-for-software-engineers-to-discuss-programming-practices-and-methodologies" rel="nofollow noreferrer">a</a> <a href="https://meta.stackoverflow.com/questions/252777/is-there-a-less-restrictive-stack-exchange-site-specially-suited-for-not-too-spe">bit</a> and probably haven't found the right medium for this question so let me know if there's a different forum I should bother. </p>
<p>First, there is an application managed by another group that does some simulations and communicates to our system via Ethernet. Let's call this App.</p>
<p>Now, we have the following setup on a Red Hat Enterprise Linux system: </p>
<ol>
<li>Legacy Ada code (used to communicate with App following a predefined
standard)</li>
<li>Linux csh/sh scripts (call Ada tasks to communicate with App or
write files to update Flash - either called by Ada tasks or
constantly running alongside program to monitor status)</li>
<li>Actionscript 2 Flash Movie in Firefox window (GUI - polls files to
see if updates are necessary and loads variables to PHP to make
system calls, call Linux scripts, or run Ada tasks)</li>
<li>PHP (used by Flash to call Linux scripts and Ada tasks to
communicate with App)</li>
</ol>
<p>I am looking for architectural improvements. Obviously the mishmash of languages is a nightmare. Above that, Flash is difficult to work with because we haven't been able to get an interrupt-driven architecture in place. I've tried to use Flash's ExternalInterface class for a more event-based flow, but whoever setup the Flash environment did so in a way that there is no available ExternalInterface. "Finally" (for this post), our program is run on a local machine, so running a .swf in a Firefox window is unnecessary. </p>
<hr>
<p>Thanks for the feedback! Let me respond to the first three comments I see: </p>
<ol>
<li>It would be an absolute dream to get time and money to rewrite the
entire system in a more coherent manner. I expect significant resistance
(because I've already tried a few times), but I will do more
research and attempt to gather more compelling cases and
communicate the "feebleness" of only updating part of the
"design". </li>
<li>You're right - I was rushing too much to think it was necessary to
know the guts. Basically I was hoping for stuff like, "My favorite
languages/tools/patterns/paradigms/etc for an architecture that
needs to have a GUI and interact with Linux is blah" or "An
interrupt driven architecture for AS2 does exist, it's blah" or
"ExternalInterface isn't available? Have you made sure that blah?".
I've updated the above with maybe more useful information. Let me
know if that didn't actually clarify anything.</li>
<li>Hopefully the previous response helps explain what the pieces do to
some degree.</li>
</ol>
<p>EDIT: I no longer work on this project, but we can keep the thread open if anyone else thinks it'll be useful for others (doubtful as I hope no one ever runs into this embarrassing situation). What ended up happening was <code><whine></code> despite repeated attempts from me and two other developers to suggest rewriting the entire application in Java/Python, we never convinced anyone. Then another developer (not on the project) volunteered to rewrite everything in Java and everyone jumped on board all of a sudden so now the whole thing is in Java (not App, but everything in 3 and 4 is now Java). <code></whine></code></p>

Generate all permutations of a list without adjacent equal elements. <p>When we sort a list, like</p>
<pre><code>a = [1,2,3,3,2,2,1]
sorted(a) => [1, 1, 2, 2, 2, 3, 3]
</code></pre>
<p>equal elements are always adjacent in the resulting list. </p>
<p>How can I achieve the opposite task - shuffle the list so that equal elements are never (or as seldom as possible) adjacent?</p>
<p>For example, for the above list one of the possible solutions is</p>
<pre><code>p = [1,3,2,3,2,1,2]
</code></pre>
<p>More formally, given a list <code>a</code>, generate a permutation <code>p</code> of it that minimizes the number of pairs <code>p[i]==p[i+1]</code>. </p>
<p>Since the lists are large, generating and filtering all permutations is not an option.</p>
<p>Bonus question: how to generate all such permutations efficiently?</p>
<p>This is the code I'm using to test the solutions: <a href="https://gist.github.com/gebrkn/9f550094b3d24a35aebd" rel="nofollow noreferrer">https://gist.github.com/gebrkn/9f550094b3d24a35aebd</a></p>

How to apply stopwords accurately in French using R. <p>I'm trying to pull a book using the Gutenberg library and then remove French stopwords. I've been able to do this accurately in English by doing this:</p>
<pre><code>twistEN <- gutenberg_download(730)
twistEN <- twistEN[118:nrow(twistEN),]
twistEN <- twistEN %>%
unnest_tokens(word, text)
data(stop_words)
twistEN <- twistEN %>%
anti_join(stop_words)
countsEN <- twistEN %>%
count(word, sort=TRUE)
top.en <- countsEN[1:20,]
</code></pre>
<p>I can see here that the top 20 words (by frequency) in the English version of Oliver Twist are these:</p>
<pre><code>word n
<chr> <int>
1 oliver 746
2 replied 464
3 bumble 364
4 sikes 344
5 time 329
6 gentleman 309
7 jew 294
8 boy 291
9 fagin 291
10 dear 277
11 door 238
12 head 226
13 girl 223
14 night 218
15 sir 210
16 lady 209
17 hand 205
18 eyes 204
19 rose 201
20 cried 182
</code></pre>
<p>I'm trying to accomplish the same thing with the French version of the same novel:</p>
<pre><code>twistFR <- gutenberg_download(16023)
twistFR <- twistFR[123:nrow(twistFR),]
twistFR <- twistFR %>%
unnest_tokens(word, text)
stop_french <- data.frame(word = stopwords::stopwords("fr"), stringsAsFactors = FALSE)
stop_french <- get_stopwords("fr","snowball")
as.data.frame(stop_french)
twistFR <- twistFR %>%
anti_join(stop_words, by = c('word')) %>%
anti_join(stop_french, by = c("word"))
countsFR <- twistFR %>%
count(word, sort=TRUE)
top.fr <- countsFR[1:20,]
</code></pre>
<p>I did alter the code for the French stopwords based on info I found online, and it is removing some stopwords. But this is the list I'm getting:</p>
<pre><code>word n
<chr> <int>
1 dit 1375
2 r 1311
3 tait 1069
4 re 898
5 e 860
6 qu'il 810
7 plus 780
8 a 735
9 olivier 689
10 si 673
11 bien 656
12 tout 635
13 tre 544
14 d'un 533
15 comme 519
16 c'est 494
17 pr 481
18 pondit 472
19 juif 450
20 monsieur 424
</code></pre>
<p>At least half of these words should be getting captured by a stopwords list and they're not. Is there something I'm doing wrong in my code? I'm new to tidy text, so I'm sure there are better ways to get at this.</p>

Updating a mutable named set in nftables with responses from bind. <p>I need to apply an <code>nftables</code> rule to all traffic originating from a specific host, but the packets will not necessarily include the proper FQDN, so I need to rely on the IP address(s). The issue is that there are multiple redundant IP's returned for the FQDN that may change order/priority from time to time, or may even be replace entirely. </p>
<p>Because there are multiple IP's returned, I have to use a mutable named <code>set</code>, but I need that set to update somewhat regularly to ensure we have an up to date list of IP's to match against.</p>
<p>We have BIND9 (<code>named</code>) on the server so my thought is that I could have a cron job script that:</p>
<ol>
<li>Flush the local dns resolver for the the FQDN with <code>rdnc flushname...</code>, </li>
<li>Then dig against it to update the resolver cache with <code>dig +short...</code>, </li>
<li>Run <code>nft add element...</code> with the new ones,</li>
<li>Flush the old named set with <code>nft delete element...</code></li>
</ol>
<p>Is this the right way to go about this, or have I overthought something thats already been solved another way?</p>

Not able to access file via SMB but able to access from NTFS. <p>I have a strange problem.</p>
<p>I have a file uploaded by some colleague via mapped drive. She is able to read the file after uploading. She has write/read/execute/list NTFS permission, and I see she is the owner of files.</p>
<p>Then some other colleague tell me she can't read these files via mapped drive, they have the same NTFS permission and sharing permission.</p>
<p>Then I test by myself, directly on the server:
1. I can't read either from mapped drive, and I logged as admin user
2. I can read it, via NTFS physical drive.
3. All sharing is inherited from the sharing root.</p>
<p>From ACL checking everything is correct. Other folders/files from the same sharing root is ok.</p>
<p>Do you have any ideas?</p>

I knew I was fat, when blind people knew I was fat. . Years ago I worked for for a state Deaf/Blind school, I am an ASL interpreter. I always knew I was chunky, big boned, hardy, whatever other terms I could use to describe my physical appearance without admitting I was obese. What bothered me more than my physical appearance, was knowing how unhealthy I was.
One day after walking up two flights of stairs to get to my office, a blind co-worker asked if I was alright. I was confused and responded "yes, why?" He told me he could hear me breathing heavy and was concerned. I had to confess that I was out of breath because walking up the stairs was difficult for me. He responded "oh, I didn't know you were overweight." I was crushed and thought that was incredibly insensitive of him.
I wanted to crawl in a hole and die. I was mortified, ashamed, embarrassed. He couldn't see that I no longer fit into my jeans, he couldn't see my discomfort in my office chair, he was oblivious to my physical appearance. He knew my body was failing me, or I was failing my body and he didn't even have to see me to know it.
That day everything changed. I got a gym membership that afternoon, asked my friends to support me and lost 100 pounds that year. I've kept it off for 5 years now and often think of the man who heard my fat. But, after I lost the weight, while I worked there I made it a point to make him hear me running up the stairs -- without panting or wheezing. Proving to us both that I was no longer out of shape.
Sometimes you need to hear the things you already know.
Tl;dr - I was so overweight that a blind person commented on my heavy breathing after walking two small flights of stairs that I changed my life and lost 100 pounds. Now I thank him every time I walk up stairs. | 0non-cybersec

Postgres: query on huge (11gb ) index does not return. <p>Using Postgres 9.6, I have created a table with 435M rows which is 120GB in size and have added an index which is 11GB in size.</p>
<p>I now want to iterate on the distinct values of the index, but the query fails with no error, it just does not complete. I can see no cpu usage or ram being used. Nb the server is on aws rds with 15GB of ram. </p>
<p>How to best troubleshoot this? Trying to iterate through it with <code>LIMIT</code> and <code>OFFSET</code> fails after about 3 cycles. I haven't managed to get a number of the unique values in the index. </p>
<p>I will try reindexing to see if there is indeed anything corrupted, but any suggestions on using a 11GB index would be great. </p>
<p>Editing to add more info:</p>
<p>This is the format of my table</p>
<pre><code>id bigint,
hit1 character varying(50),
hit2 character varying(50),
offset integer,
year character varying(50)
</code></pre>
<p>Row estimate is at 431M rows, approx size at 115GB according to postgres. </p>
<p>Index is on hit1 column with a size of 11GB. </p>
<p>I am trying to calculate the counts of hits:</p>
<pre><code>select hit1,hit2, count(distinct id) as total_count_of_ids,
count(case when offset=-1 then 1 else null end) as prev_position,
count(case when offset=0 then 1 else null end) as same_position,
count(case when offset=1 then 1 else null end) as next_position,
min(cast(substring(year,1,4) as int)) as min_year,
max(cast(substring(year,1,4) as int)) as max_year,
array_agg( id) as id_list
from table where hit1=''
group by hit1, hit2;
</code></pre>
<p>As the table is big, I have opted to do this one by one entity like so: </p>
<pre><code>select distinct hit1 from table limit 250 offset x
-- use above query to to store results into table.
</code></pre>
<p>This function is wrapped in another function which provides x from a loop. The function is run in a dblink context so that the results can be stored and I can audit as I go along. </p>
<p>The cycle needs to run 1,000,000, I am yet to get a number for the count of distinct hit1 values as the query takes too long to come back. The first 750 values (3 iterations) come back on the iteration in under a minute each, but at the next iteration is where it keels over. I will provide log data when this iteration dies. </p>
<p>While the query is running (at the time when the distinct list is calculated) there seems to be minimal cpu usage. There also seems to be some memory being unavailable. </p>

In the functions I use dblink for auditing. After the first 3 cycles (0-2) it takes one hour to return results from
select distinct hit1 from table limit 250 offset 750;
compared to the previous hit1 order this one is no alphabetical and it seems to return or die only 77 results in. </p>

Does anyone else have a hard time remembering names in anime?. So I’m not like a huge anime fan but my friend recently got me to watch My Hero Academia online and I have to say, I loved it. Idk something about those characters, the balance of humor and seriousness, overall world design just really appealed to me. But after talking to my friend about it I realized I only really remembered the name of Deku (because he’s the main character and it’s a relatively short name) and Tsu (because she shouts “I said call me Tsu” like all the time to Deku). And those aren’t even my favorite characters or anything it’s just by chance I remembered them, Raven bird guy and Robo legs are probably my favorite.
I’m bad at memorizing names, even English names but for anime because a lot the the names (to me at least) sound extremely foreign and i’v never heard them before i guess they just go in one ear and out the other.
I’v had this issue with other anime’s that I actually kind of enjoyed like Soul Eater (I only remember the names of Makah? And Kid death) even though I watched that entire series.
Same with the Devil is a Part Timer, fucking loved the series, watched every episode but as of right now, I can’t remember the names of anyone. (Which is embarrassing because I think there’s only like 5 important characters)
Out of all the anime’s I’d watched, the only one where I didn’t have this issue with was Full Metal Alchemist, I think it might be the names are western are maybe they just shout them more? Idk
I’m just asking if anyone else has this issue when watching anime. | 0non-cybersec

how to unzip same file name without override (capitalization differ). <p>I have 2 files named xt_DSCP.h and xt_dscp.h in the same directory, in a zip file. I am trying to unzip them on my pendrive but I only have 2 options: skip or override. </p>
<p>I was searching for a solution but only found how to force override but I am actually trying to do the exact opposite. </p>
<p>File system is FAT32. I know that on NTFS it is not possible but FAT32 should allow it. I already unzipped the folder successfully in linux OS. Main goal is to use it in windows, however, which is why I am trying to pass it to pen drive on linux. Any attempt always resulted in overwritten files :(</p>
<p>can someone help? </p>

Integration of $I_n=\int_{0}^{1} \frac{x^n}{\sqrt{x^3+1}}dx$. <p>Let $I_n=\int_{0}^{1} \frac{x^n}{\sqrt{x^3+1}}dx$. Show that $(2n−1)I_n+2(n−2)I_{n-3}= 2\sqrt{2}$ for all $n\geq3$. Then compute $I_8$.</p>
<p>How do I compute that integral? My idea was to reduce it to some known forms, as $\int\frac{1}{\sqrt{1-x^2}}dx$... Is there any way to solve the problem without computing the integral though?</p>

AITA for not allowing my 11-year-old daughter to have a boy sleep over our house?. As I said, my daughter’s 11 and her friend group ranges 11-12. It’s mainly girls but there is one boy that I have seen around.
She’s having a sleepover to celebrate her birthday this weekend. She invited the boy to the party but the plan was (or so I thought) that he would leave around 10 pm.
The boy’s mom called me last night to confirm that the boy (I’ll call him Tom) could sleep over. I said there must have been some miscommunication and I thought that she was picking up Tom at 10. I told her that if transportation was a problem my husband or I could drive Tom home.
Tom’s mom said that the issue was Tom wanted to stay over and would be let down if he had to go home. (Again, I don’t know why she thought he was sleeping over, since I made it clear on the invitation what was expected. We will have a couple other boys over who are the kids of family friends and they will also be leaving at 10 pm!).
It was a sort of awkward conversation to say the least. But she ended up saying she would come to pick up Tom after the party.
To be honest, even if I was inclined to have Tom sleep over, I doubt husband would go for it. But I’m starting to wonder if I did something wrong here? | 0non-cybersec

Locked out by permissions on an internal 4TB drives problem. <p>This is my 2nd time around with an internal 4 TB drive or greater. And I seem to have continuous problems with permissions. I also had as problem with an external 6 TB drive and permissions. This has been happening on different computers. All were all running a Linux system. All drives were running an EXT4 system. I seems to have solved the problem with the external drive by formatting it as a NTFS files system.</p>
<p>However, on internal drives, I should be able to run them as a EXT4 files system. What happens is that I format them, then loose permissions to them after I re-boot. I can access them, but can not do anything else. I can not post files to them or create internal directories.</p>
<p>I've had the same problem with Ubuntu Gnome and Mint. What do I need to do, format them as NTFS drives?</p>
<p>I have tried the various 'chrown' and 'chmod' commands with various settings. No help. I get the message that permissions have been changed, then I access the drive. No change.</p>
<p>On one computer, my home directory was encrypted. On the other computer, it was not.</p>
<p>All hardware has been replaced and updated. New CPU. New motherboard. New power supply. New memory. Etc.</p>
<p>Tried: cd /media/lloyd/SyS_10</p>
<pre><code> sudo chmod -R -v 777 *
</code></pre>
<p>No help</p>
<p>Tried: cd /media/lloyd/SyS_10</p>
<pre><code> sudo chown -R -v lloyd:lloyd *
</code></pre>
<p>Again, no help.</p>
<p>Also tried some other things, which did not help. But can't remember the sequence.</p>
<p>Common points between them:</p>
<ol>
<li><p>Running a Linux system. Different flavors and different computers. (Ubuntu Gnome 17.10 and Mint 18.3.)</p></li>
<li><p>Drives formatted as EXT4 (BIOS supports large drives.)</p></li>
<li><p>Drives were equal or greater than 4 TB.</p></li>
</ol>
<p>Common problems:</p>
<ol>
<li><p>Assigned all permissions to these drives to ROOT.</p></li>
<li><p>All stated that I did not have ROOT Permissions.</p></li>
</ol>
<hr>
<p>It appears to me as if there is a bug in either Ubuntu or EXT4 when using multiple drives and those additional drives are larger than 2 TB. (I am leaning towards thinking that the bug is in EXT4 where the additional drives are larger than 2 TB.) This bug does not seem to affect the main drive. Sda1 or sda2 drive.</p>

~Dear reader,
I am the one you’ve come to know as Uncle. I have been posting the Nephew stories to you over the past month or so. What follows is what would become Nephew’s last account of his time within the domicile. The boy was too kind for the world he was brought up in. Kindness leads to destruction in a place like this, as I know too well myself. I hope this last piece of the story brings peace of mind and understanding.~
It has been so long since I last reached out to you in your other world. Uncle returned immediately after I finished my last message but he would not look at me. His eyes remained fixated on the thing in the corner. I tried to ask him about it but he wouldn’t listen. A profound sadness welled up in his eyes as he stared.
After a short while he reached out towards me with his hand, imploring me to share my note with him. I did and he took his leave. I have not seen Uncle since. I want to believe he’ll return but I can’t be certain.
Everyone has left now.
I almost thought Father would never leave me. My constant captor. But he did.
First Mother, then Father, now Uncle. All there is left is me and the thing in the corner. Although I don’t think I could call it that anymore, it has grown to fill the domicile almost entirely. It is everywhere, on the ceiling, across the floor, over the window. The only place it isn’t is Father Corner, where I sit wedged in the spot where Father once vigilantly watched over me.
I can’t know for sure where Father went. He just disappeared one day. I woke up and he was gone. That was the moment the whole situation sunk in. I may have been living with a faceless, writhing creature slowly oozing out of the corner that Mother once stood in but at least I wasn’t facing it alone. The true horror lies in the loneliness. Although Father frightened me at the best of times I always believed he would protect me from the thing. He may not have been able to see it but I believed his presence was enough to keep it at bay. Maybe I was right, but now I’ll never know.
I believe that seven days have past since I last saw the face of Father. I hold no hope of seeing him again. As for Uncle, the thing is stretched across the window where he once stood. I once thought I saw his silhouette peering through the thing’s fleshy mass of veins and cartilage but I can’t know for sure. He too has abandoned me. I write this note not for his sake but for my own. I don’t expect him to find it once this is all over and I don’t expect anyone to read it. I am only keeping up this charade in order to stop myself from looking directly into the thing that now surrounds me at every side. For if I did I would surely go mad.
To write is to keep my mind active, to keep my eyes away from the thing that even now I can hear pleading with me to look in its direction. It’s speaking to me, but not quite. There are no spoken words, only pulses of thoughts. It’s in my head, whispering to me slowly and rhythmically so that I look at it. I don’t want to, but I will eventually. I know it. I’ll try to fight it as best I can for now but It won’t be long I’m sure. Mother is gone, Father and Uncle were close behind. Nobody is coming to save me from this thing. I’ll either die writing in this corner or do as it wants. Then I’ll probably die anyway, or worse.
I can see it peripherally, bending about the room with its limbs broken around every corner. I dare not look into its core. That bloated centre mass in the corner hanging like a mutated shadow of the woman who once stood there. How could she leave me? Did she ever even love me? I’m her son.
The thing in the corner is shifting, those mangled branches inching ever closer to where I sit and write this note. The only way I can truly describe it is to call it wrong. A thing that belongs neither in this world or the other. I dare not wonder what lies beneath its bubbling and twitching skin. When I think of it I imagine the ways in which it could take me. At any moment one of those horrible extremities could reach down from anywhere and snatch me up. But it hasn’t. I’m not certain why, possibly because it likes taunting me with its disfigured shape. Playing with me.
Maybe I could peek at the thing very quickly. So fast that it won’t even notice I was ever looking. Yes, I think that might work. I’ll look and immediately look back to the page to jot down what I see. This will work. It cannot know I looked. But I will.
I looked.
I remember the day I was brought here. I remember my birth. The thing told me. As soon as I looked, I knew.
The thing has a name, one I cannot write. It is too long and too old, but I know that the thing is not just a thing. It is no more a thing than you or I could be considered a thing. It has consciousness, a mind, a capacity for complex thought, a family, a lineage, a home, a domicile, a name.
It was January 8th. The moon was indeed pale but I was not born under it. It was visible through the window. The window where nobody stood, no Uncle. This domicile was different, it was wholly white and clean. The creatures around me were not shrouded in shadow, they were in the light, staring down at me with happy faces. Except for Mother. Mother was there in the shadows under every bed, behind every door and in every corner. The thing with a name was there too.
I remember it as a happy place. I know that changed once I left. Once Mother stepped forward to carry me across the fields and into the domicile. Mother and the thing with a name robbed the place of its happiness, they robbed it of me.
Mother took me back to the domicile where I now sit and write this note. I do not know how different my life would have been if the happy people had kept me in their bright, beautiful domicile, but something about the memory of that place feels right. It feels like home.
Father didn’t know about Mother’s plan to take me, to raise me in the domicile. When Mother entered with me in her arms he initially tried to return me to the happy people. That's when the thing with a name made itself known, he knew he couldn’t fight it. So he made the decision to keep me, for that is what Mother wanted, or what the thing with a name made her want. He decided to raise a son he knew was not his own, a son who was not even from his own world. He was forced to serve the thing with a name.
The thing that has had many names over its long life. The thing I knew as Mother.
Mother didn’t leave the domicile, she only turned her back to it. She’s still here. Behind the thing with a name that grew inside her for so many years. The thing that told her to take me from the loving arms of the happy people. The thing that Father tried to protect me from, the thing that stole him away into the contorted lump of flesh it calls a body. The thing that scared Uncle so much that he fled, abandoned me to the mercy of this thing. This thing that has a name.
I must go to it now. I saw into the eye of the thing and it showed me my past, but it also showed me my future. In it I join Mother and Father inside the thing. So that is what I must do.
I don’t expect Uncle to ever return to the domicile, so my tale will go untold. But if he should, I’d like him to know that I understand why he did it. His cowardice has spared his life. In exchange for mine. I forgive you Uncle.
And to you my friend from another world, I expect you are worried for me but you should not be. The thing with a name knows all and this is the way it should be, the way it has always been. Maybe we will meet one day, when the thing with a name comes to you. Until that day, I wish you the best. Now I must join my family.
~This is where the boy’s note ends. I retrieved it from what was left of the domicile. I am deeply sorry.
Sincerely,
The one you know as Uncle.~

Recovering broken Ubuntu installation. <p>I have not updated Ubuntu for quite some time and then I went from version 15.04 to 16.04 (which succeeded) and then immediately I tried to go to 16.10. This however failed mid-upgrade and the installation got corrupted (I can "log in" but do nothing, recovery mode does not work).</p>
<p>Using USB boot, I managed to get to the filesystem with the intention to recover my date, however I encountered the problem that some of them are apparently protected and I do not have the rights to do basically anything with them. Is there a way to:</p>
<p>1) Copy them using live USB to a backup, so that I can simply format the partition and reinstall the system? Of course I do remember the login/password to the previous installation?</p>
<p>2) Install Ubuntu over the previous one without formatting, thus preserving the old data and be able to access them (even though they originate from a previous instance)?</p>
<p>Also please bear in mind that I am just a regular user with regards to Ubuntu, so any instruction will have to be probably fairly specific:)</p>

How to use takeWhile with an Iterator in Scala. <p>I have a Iterator of elements and I want to consume them until a condition is met in the next element, like:</p>
<pre><code>val it = List(1,1,1,1,2,2,2).iterator
val res1 = it.takeWhile( _ == 1).toList
val res2 = it.takeWhile(_ == 2).toList
</code></pre>
<p><code>res1</code> gives an expected <code>List(1,1,1,1)</code> but <code>res2</code> returns <code>List(2,2)</code> because iterator had to check the element in position 4. </p>
<p>I know that the list will be ordered so there is no point in traversing the whole list like <code>partition</code> does. I like to finish as soon as the condition is not met. Is there any clever way to do this with Iterators? I can not do a <code>toList</code> to the iterator because it comes from a very big file.</p>

Ubuntu server 12.04 having 7GB disk usage discrepancy. <p>I did a fresh install of ubuntu server 12.04 as a KVM virtual guest. I used a kickstart file to automate the installation, I've included the command to create the guest as well as the partitioning section of the kickstart file. These numbers were taken right after a fresh installation the only main service that is running is an ssh server. There is 7GB of disk usage that I can't account for. </p>
<p><strong>Kickstart partitioning section</strong></p>
<pre><code>part /boot --fstype ext4 --size 200
part / --fstype ext4 --size 1 --grow
</code></pre>
<p><strong>KVM installation command</strong></p>
<pre><code>virt-install -n bigtest -r 4096
--disk path=/var/lib/libvirt/images/bigtest.img,bus=virtio,size=500 \
-c ubuntu-12.04.1-server-amd64.iso --accelerate
--network=bridge:br0 --connect=qemu:///system \
--vnc --noautoconsole -v --os-type linux
</code></pre>
<p><strong>disk usage</strong></p>
<p>Running df and du reports different disk usages, which I understand can happen. The difference though of 8G vs 512M is about 7G. </p>
<pre><code>root@ubuntu:~# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda5 500G 8.0G 467G 2% /
udev 2.0G 4.0K 2.0G 1% /dev
tmpfs 792M 220K 791M 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 2.0G 0 2.0G 0% /run/shm
/dev/vda1 188M 34M 146M 19% /boot
root@ubuntu:~# du -hs /
512M /
</code></pre>
<p><strong>Small Guest Test</strong></p>
<p>In the guest called bigtest the virtual disk was 500GB. When I create another guest called smalltest with a virtual disk of size 10GB, the numbers for df and du are 764M and 512M.</p>
<p><strong>KVM host reports</strong></p>
<p>Now if we look at the size of the kvm image files on the host file system we get another interesting story.</p>
<pre><code>root@vbox1:/var/lib/libvirt/images# du -hs *
753M bigtest.img
744M smalltest.img
</code></pre>
<p><strong>Reserved filesystem blocks</strong></p>
<p>Just to rule out other stuff as much as possible all these numbers were taken after I set the reserved blocks percentage to 0%.</p>
<pre><code>root@ubuntu:~# tune2fs -m 0 /dev/vda5
tune2fs 1.42 (29-Nov-2011)
Setting reserved blocks percentage to 0% (0 blocks)
</code></pre>
<p><strong>The Question</strong></p>
<p>What is taking up this 7GB of physical space. If it is used why isn't that being reflected in the host file system disk usage. </p>
<p><strong>UPDATE 1</strong></p>
<p>I discovered something very interesting. If you I run the following commands and reboot the new numbers for df and du are 1.1G and 875M! which are within normal expectations.</p>
<pre><code>apt-get update
apt-get upgrade
apt-get dist-upgrade
</code></pre>
<p>Here are a few observations I made about this:</p>
<ol>
<li>After a fresh install I tried rebooting many times it didn't change the 8GB usage</li>
<li>running apt-get update and upgrade don't reduce the disk usage, even with reboots.</li>
<li>only when the kernel is updated with apt-get dist-upgrade, and even then only after the system has rebooted with the new kernel will the usage drop back to normal levels.</li>
</ol>
<p><strong>UPDATE 2</strong></p>
<p>I've tested this independently in virtualbox and this same exact behaviour happens. So this issue is related to Ubuntu Server and not anything specifically related to KVM or virtualbox.</p>
<p><strong>UPDATE 3</strong></p>
<p>Some additional commands run on the machine as suggested in an answer below.</p>
<pre><code>root@ubuntu:/# du --apparent-size -sh --exclude=/proc /
963M /
</code></pre>

Locking down external drive reads in a permanent fashion on Linux?. <p>Is there any way to alter the way a Linux distribution handles external drives to only allow read-only unless additional credentials are provided, or at least permanently disable it?</p>
<p>Basically need it such that if someone plugs a drive into a system with sensitive data, they cannot copy anything off, even with admin rights. </p>
<p>I'm working with Ubuntu 16.04 specifically, and ideally I'd need to do a bunch of setup on the system before disabling this functionality, so I'm not sure if say, modifying and recompiling the OS is possible. Ideally this needs to be a fairly difficult thing to overcome on the machine. </p>

How to use spot instance with amazon elastic beanstalk?. <p>I have one infra that use amazon elastic beanstalk to deploy my application.
I need to scale my app adding some spot instances that EB do not support.</p>
<p>So I create a second autoscaling from a launch configuration with spot instances.
The autoscaling use the same load balancer created by beanstalk.</p>
<p>To up instances with the last version of my app, I copy the user data from the original launch configuration (created with beanstalk) to the launch configuration with spot instances (created by me).</p>
<p>This work fine, but:</p>
<ol>
<li><p>how to update spot instances that have come up from the second autoscaling when the beanstalk update instances managed by him with a new version of the app?</p>
</li>
<li><p>is there another way so easy as, and elegant, to use spot instances and enjoy the benefits of beanstalk?</p>
</li>
</ol>
<p><strong>UPDATE</strong></p>
<p>Elastic Beanstalk add support to spot instance since 2019... see:
<a href="https://docs.aws.amazon.com/elasticbeanstalk/latest/relnotes/release-2019-11-25-spot.html" rel="nofollow noreferrer">https://docs.aws.amazon.com/elasticbeanstalk/latest/relnotes/release-2019-11-25-spot.html</a></p>

Foilum map module, trying to get more options for marker colors. <p>I am playing with Folium a lot right now and its really great to have something so easy to use in Python. But their documentation is seriously behind, which I understand. So I have 2 questions.</p>
<ol>
<li>What am I doing wrong in how I am trying to get more marker colors? Here is what I have tried:</li>
</ol>
<p><code>map.simple_marker(each_coord, popup=v[0], marker_color='#FFFF00')</code>
<code>map.simple_marker(each_coord, popup=v[0], marker_color='yellow')</code>
<code>map.simple_marker(each_coord, popup=v[0], marker_color='Yellow')</code></p>
<p>They should all make the marker yellow, instead it stays default red. The only colors I can actually change to are red, green, and purple. In an example from the folium documentation it looks like we should be able to use html color codes:</p>
<pre><code>folium.CircleMarker([45.5215, -122.6261],
radius=500,
popup='Laurelhurst Park',
color='#3186cc',
fill_color='#3186cc',
).add_to(map_2)
</code></pre>
<p>But it doesn't work for me. Hope someone knows a way around this because I need at least 12 different colors for my project.</p>
<ol start="2">
<li>The way I am adding markers seems to be deprecated. It works, but I always get this warning: <code>FutureWarning: simple_marker is deprecated. Use add_children(Marker) instead</code> which I think might be related to why I can't get the colors to work. But their is nothing in any of the documentation or open discussions about how to use <code>add_children</code> Maybe someone with knowledge can clarify?</li>
</ol>
<p>Thanks</p>

What are some recipes/foods that doesn't become disgusting after 5 ~ 11 hours?. I'm looking to bring my own lunch/dinner to school now due to buying food costs $12 everyday. However , my biggest concern is coming up with a meal/recipe that won't become disgusting or not edible after certain hours.
Usually I would take out the food at 7:30AM with me and I will be at school until usually 8:00PM.
around 10:30AM I usually eat almond or cheese string , at 1:00PM I grab lunch , then at 6:00PM I eat dinner.
So , if I were to pack my lunch/dinner , it would be consumed after 5 ~ 11 hours , but is it safe to eat foods that has been out for that long at room temperature(I have a locker where I can store them)?
We also have microwaves/hot water at school , so if these can of any use to improvise any recipes that would be appreciated as well.
Thank you in advance. | 0non-cybersec
