Completely unable to install python2.7-dev

- by gath

Am totally stuck! Am unable completely to install python2.7-dev on my Ubuntu13.04. I have tried all the tricks mentioned on this site (askubuntu.com) and many other sites on the web but still nothing! Am running Ubuntu 13.04 64bit on a virtualbox, but every time I run sudo apt-get install python2.7-dev, I get the following error; python2.7-dev : Depends: python2.7 (= 2.7.3-0ubuntu3.5) but 2.7.4-2ubuntu3 is to be installed Depends: libpython2.7 (= 2.7.3-0ubuntu3.5) but 2.7.4-2ubuntu3 is to be installed Depends: libexpat1-dev but it is not going to be installed Depends: libssl-dev but it is not going to be installed E: Unable to correct problems, you have held broken packages. I've tried to do apt-get update, but still nothing! I've even tried installing Python2.7 from sources, but still nothing doing! Is there a single package with all the dependencies I can download, that can just install everything (Python2.7-dev) or is there another trick I can use to get the Python-dev headers installed on my machine. Hint: I've noticed when I run sudo apt-get update , somewhere along the updates I've seen some errors; ...

configure vpn so that it is not the preferred route

- by pstanton

Hi all, I recently re-installed XP on my PC. I had a vpn set up on the old system and remember being advised to change one setting so that it wasn't the preferred route for all network traffic. This was ideal as only connections to the target network would be made through the vpn and all normal traffic would go through the regular path unmolested. i remember thinking "why isn't this the default setting!?". now i've formatted my drive and lost the config for that vpn (besides host, username, passwd). does anyone know of the setting i'm referring to? thanks, paul.

OUCH! Laptop running SUPER HOT after 12.10 upgrade!

- by dinkelk

I was running 12.04 for 6 months, my laptop ran almost silently and cool enough to hold on my lap. I updated to 12.10 and now my computer gets too hot to hold on my lap and the fan is constantly running on full blast. This is the output of sensors: acpitz-virtual-0 Adapter: Virtual device temp1: +84.0°C (crit = +99.0°C) coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +84.0°C (high = +86.0°C, crit = +100.0°C) Core 0: +74.0°C (high = +86.0°C, crit = +100.0°C) Core 1: +72.0°C (high = +86.0°C, crit = +100.0°C) Core 2: +75.0°C (high = +86.0°C, crit = +100.0°C) Core 3: +84.0°C (high = +86.0°C, crit = +100.0°C) radeon-pci-0100 Adapter: PCI adapter temp1: +76.0°C I have an HP Pavilion dv6, i7, amd radeon graphics. Please let me know if you need additional information. What could be different between the two Ubuntu editions that caused such a drastic change? Edit 1: Per @Paul's suggestion, I ran htop to try to narrow down the problem. Here is the result! (left side of terminal) (right side of terminal) This is about 10 minutes after boot-up, htop, yakuake, and a chrome page with 1 tab opened to this question are all that I have manually opened. The most taxing program to the CPU is htop itself. I think that the problem must lie elsewhere; my temps are already up to ~65C for the CPU and ~69C for the GPU, with nearly 0% CPU usage.

Nginx Tornado Combination Causing 502 Bad Gateway Errors

- by PlaidFan

We are facing a problem with inconsistent 502 errors and tracking down the reasons has been a very frustrating exercise. We can reproduce the problem by sending several simultaneous requests quickly. The problem is that several is only in the range of 10 to 20 within a 5 seconds (not a typo). So clearly this type of load should be handled easily. We really like the Nginx + Tornado approach but are considering going to a more traditional (e.g. threading) approach because this problem has been very difficult to solve. I was wondering if you a) know how to fix this issue and b) how we can tracked down the culprit(s). The log files simply identify there being a connection refused. We have the same problem as this post: How do I debug a HTTP 502 error? But there is no answer provided on how to solve the problem so I'm hoping you can help because this may be a common issue with this type of setup. Thanks in advance, Paul

How to use pipes for nonblocking IPC (UART emulation)

- by codebauer

I would like to write some test/emulation code that emulates a serial port connection. The real code looks like this: DUT <- UART - testtool.exe My plan is to use create a test application (CodeUnderTest.out) on linux that forks to launch testool.out with two (read & write) named pipes as arguments. But I cannot figure out how to make all the pipe IO non-blocking! The setup would look like this:. CodeUnderTest.out <- named pipes - testTool.out (lauched from CodeUnderTest.out) I have tried opening the pipes as following: open(wpipe,O_WRONLY|O_NONBLOCK); open(rpipe,O_RDONLY|O_NONBLOCK); But the write blocks until the reader opens the wpipe. Next I tried the following: open(wpipe,O_RDWR|O_NONBLOCK); open(rpipe,O_RDONLY|O_NONBLOCK); But then the reader of the first message never gets any data (doesn't block though) I also tried adding open and close calls around each message, but that didn't work either... Here is some test code: #include <stdio.h> #include <sys/types.h> #include <unistd.h> #include <fcntl.h> pid_t pid; char* rpipe, *wpipe,*x; FILE *rh,*wh; int rfd,wfd; void openrpipe( void ) { rfd = open(rpipe,O_RDONLY|O_NONBLOCK); rh = fdopen(rfd,"rb"); printf("%sopeningr %x\n",x,rh); } void openwpipe( void ) { //Fails when reader not already opened //wfd = open(wpipe,O_WRONLY|O_NONBLOCK); wfd = open(wpipe,O_RDWR|O_NONBLOCK); wh = fdopen(wfd,"wb"); printf("%sopeningw %x\n",x,wh); } void closerpipe( void ) { int i; i = fclose(rh); printf("%sclosingr %d\n",x,i); } void closewpipe( void ) { int i; i = fclose(wh); printf("%sclosingw %d\n",x,i); } void readpipe( char* expect, int len) { char buf[1024]; int i=0; printf("%sreading\n",x); while(i==0) { //printf("."); i = fread(buf,1,len,rh); } printf("%sread (%d) %s\n",x,i,buf); } void writepipe( char* data, int len) { int i,j; printf("%swriting\n",x); i = fwrite(data,1,len,rh); j = fflush(rh); //No help! printf("%sflush %d\n",x,j); printf("%swrite (%d) %s\n",x,i,data); } int main(int argc, char **argv) { rpipe = "readfifo"; wpipe = "writefifo"; x = ""; pid = fork(); if( pid == 0) { wpipe = "readfifo"; rpipe = "writefifo"; x = " "; openrpipe(); openwpipe(); writepipe("paul",4); readpipe("was",3); writepipe("here",4); closerpipe(); closewpipe(); exit(0); } openrpipe(); openwpipe(); readpipe("paul",4); writepipe("was",3); readpipe("here",4); closerpipe(); closewpipe(); return( -1 ); } BTW: To use the testocd above you need to pipes in the cwd: mkfifo ./readfifo mkfifo ./writefifo

Sync Framework Peer Data Sharing Unable to Catch Conflicts, Source Provider Alwasy wins!

- by Belliez

Hi, I am using SQL Server 2008 and the WebSharingAppDemo-SqlProviderEndToEnd sample and this is almost perfect for my needs however I am unable to detect conflicts. By default ConflictResolutionPolicy is set to ApplicationDefined. I have tried setting the ResolutionPolicy to SourceWins, DestinationWins or ApplicationDefined and I always get the same results? The Destination Provider Proxy (Peer) always wins? Can someone please provide a sample of how I can detect a conflict and act upon it or point me in the right direction where I can start to look. I am not sure what to do and where I can create events for detecting collisions. Been staring at this too long now and going around in circles! Thanks in advanced. Paul

Algorithm for nice graph labels for time/date axis?

- by Aaron

Hello, I'm looking for a "nice numbers" algorithm for determining the labels on a date/time value axis. I'm familar with Paul Heckbert's Nice Numbers algorithm (http://tinyurl.com/5gmk2c). I have a plot that displays time/date on the X axis and the user can zoom in and look at a smaller time frame. I'm looking for an algorithm that picks nice dates to display on the ticks. For example: Looking at a day or so: 1/1 12:00, 1/1 4:00, 1/1 8:00... Looking at a week: 1/1, 1/2, 1/3... Looking at a month: 1/09, 2/09, 3/09... The nice label ticks don't need to correspond to the first visible point, but close to it. Is anybody familar with such an algorithm? Thanks

Testing C++ program with Testing classes over normally used classes

- by paultop6

Hi Guys, This will probably be a bot of a waffly question but ill try my best. I have a simple c++ program that i need to build testing for. I have 2 Classes i use besides the one i actually am using, these are called WebServer and BusinessLogicLayer. To test my own code i have made my own versions of these classes that feed dummy data to my class to test it functionality. I need to know a way of somehow, via a makefile for instance, how to tell the source code to use the test classes over the normally used classes. The test classes are in a different "tester" c++ file, and the tester c++ file also has its own header file. Regards Paul P.S. This is probably a badly worded question, but i dont know any better way to put my question.

Sorting an array in PHP based on different values

- by Jimbo

I have an array whose elements are name, reversed_name, first_initial and second_initial. A typical row is "Aaron Smith", "Smith, Aaron", "a", "s". Each row in the array has a first_initial or second_initial value of "a". I need to display the rows alphabetically but based on the "a" part, so that either the name or reversed_name will be displayed. An example output would be: Aaron Smith Abbot, Paul Adrian Jones Anita Thompson Atherton, Susan I really have no idea how to sort the array this way so any help will be much appreciated!

Do I really need cmake for build automation?

- by PMiller

I'm currently investigating cmake to allow automatic building on the Win32 platform. For all runtimes and libraries I'd like to build, Visual Studio (2008/2010) projects do allready exist. I've come across cmake, but I'm unsure if I really need it. As the documentation says, cmake generates VS projects and they then can be built e.g. using MSBuild. As the projects itself allready do exist (and build nicely via the IDE or MSBuild on the cmd line), what do I need and use cmake for? Just for directory/project folder traversal? Build failure reporting? Regards, Paul

'schema' design for a social network

- by Alan B

I'm working on a proof of concept app for a twitter style social network with about 500k users. I'm unsure of how best to design the 'schema' should I embed a user's subscriptions or have a separate 'subscriptions' collection and use db references? If I embed, I still have to perform a query to get all of a user's followers. e.g. Given the following user: { "username" : "alan", "photo": "123.jpg", "subscriptions" : [ {"username" : "john", "status" : "accepted"}, {"username" : "paul", "status" : "pending"} ] } to find all of alan's subscribers, I'd have to run something like this: db.users.find({'subscriptions.username' : 'alan'}); from a performance point of view, is that any worse or better than having a separate subscriptions collection? also, when displaying a list of subscriptions/subscribers, I am currently having problems with n+1 because the subscription document tells me the username of the target user but not other attributes I may need such as the profile photo. Are there any recommended practices for such situations? thanks Alan

Trying to speed up a SQLITE UNION QUERY

- by user142683

I have the below SQLITE code SELECT x.t, CASE WHEN S.Status='A' AND M.Nomorebets=0 THEN S.PriceText ELSE '-' END AS Show_Price FROM sb_Market M LEFT OUTER JOIN (select 2010 t union select 2020 t union select 2030 t union select 2040 t union select 2050 t union select 2060 t union select 2070 t ) as x LEFT OUTER JOIN sb_Selection S ON S.MeetingId=M.MeetingId AND S.EventId=M.EventId AND S.MarketId=M.MarketId AND x.t=S.team WHERE M.meetingid=8051 AND M.eventid=3 AND M.Name='Correct Score' With the current interface restrictions, I have to use the above code to ensure that if one selection is missing, that a '-' appears. Some feed would be something like the following SelectionId Name Team Status PriceText =================================== 1 Barney 2010 A 10 2 Jim 2020 A 5 3 Matt 2030 A 6 4 John 2040 A 8 5 Paul 2050 A 15/2 6 Frank 2060 S 10/11 7 Tom 2070 A 15 Is using the above SQL code the quickest & efficient?? Please advise of anything that could help. Messages with updates would be preferable.

Selecting the most common value from relation - SQL statement

- by Ronnie

I have a table within my database that has many records, some records share the same value for one of the columns. e.g. | id | name | software | ______________________________ | 1 | john | photoshop | | 2 | paul | photoshop | | 3 | gary | textmate | | 4 | ade | fireworks | | 5 | fred | textmate | | 6 | bob | photoshop | I would like to return the value of the most common occurring piece of software, by using an SQL statement. So in the example above the required SQL statement would return 'photoshop' as it occurs more than any other piece of software. Is this possible? Thank you for your time.

Erlang code explained

- by dagda1

Hi, I am having a bit of trouble getting my head around the following erlang code -module(threesix). -export([quicksort/1]). quicksort(Pivot, Left, Right, []=_Src) -> {Left, Pivot, Right}; quicksort(Pivot, Left, Right, [H|T]=_Src) when H < Pivot -> quicksort(Pivot, [H|Left], Right, T); quicksort(Pivot, Left, Right, [H|T]=_Src) -> quicksort(Pivot, Left, [H|Right], T). quicksort([]) -> []; quicksort([H|T]=_List) -> {Left, Pivot, Right} = quicksort(H, [], [], T), quicksort(Left) ++ [Pivot] ++ quicksort(Right). I am specifically talking about the use of _Src and _List in the parameters. Are these simply for documentation as I cannot see why they are used? Thanks Paul

Lexical and dynamic scoping in Mathematica: Local variables with Module, With, and Block

- by dreeves

The following code returns 14 as you'd expect: Block[{expr}, expr = 2 z; f[z_] = expr; f[7]] But if you change that Block to a Module then it returns 2*z. It seems to not matter what other variables besides expr you localize. I thought I understood Module, Block, and With in Mathematica but I can't explain the difference in behavior between Module and Block in this example.

Creating an AST node in Erlang

- by dagda1

Hi, I am playing about with Erlang and I am trying to write a simple arithmetic parser. I want to try and parse the following expression: ((12+3)-4) I want to parse the expression into a stack of AST nodes. When parsing this expression, I would first of all create a binary expression for the (12+3) expression which would look something like this in C#: var binaryStructure = new BinaryStructure(); binaryStructure.Left = IntegerLiteralExpression(12); binaryStructure.Right = IntegerLiteralExpression(4); binaryStructure.Operator = binaryExpression.Operator != BinaryOperatorType.Addition; I am quite new to Erlang and I am wondering how I would go about creating a structure like this in Erlang that I can place on a List that I would use as the stack of expressions. Can anyone suggest how to create such a tree like structure? Would a function be a good fit? Thanks Paul

How To Aggregate API Data?

- by Mindblip

Hi, I have a system that connects to 2 popular APIs. I need to aggregate the data from each into a unified result that can then be paginated. The scope of the project means that the system could end up supporting 10's of APIs. Each API imposes a max limit of 50 results per request. What is the best way of aggregating this data so that it is reliable i.e ordered, no duplicates etc I am using CakePHP framework on a LAMP environment, however, I think this question relates to all programming languages. My approach so far is to query the search API of each provider and then populate a MySQL table. From this the results are ordered, paginated etc. However, my concern is performance: API communication, parsing, inserting and then reading all in one execution. Am I missing something, does anyone have any other ideas? I'm sure this is a common problem with many alternative solutions. Any help would be greatly appreciated. Thanks, Paul

Returning an array of tm* structs from a function

- by paultop6

Hi Guys, Im trying to create an array of tm* structs, and then return them at the end of the function. This is what i have at the moment: struct tm* BusinessLogicLayer::GetNoResponceTime() { struct tm* time_v[3]; struct tm* time_save; int s = 3; time_save = LastSavedTime(); time_v[0] = time_save; sleep(5); time_save = LastSavedTime(); time_v[1] = time_save; sleep(5); time_save = LastSavedTime(); time_v[2] = time_save; return time_v; } I understand that given the code i have now it will not be possible to return the array, because it will be destroyed when the function ends. Can anyone help me with regards to how i would go about being able to access the array from the returned value after the function has ended? Regards Paul

Erlang code critique

- by dagda1

Hi, I am trying to get my head round some basic erlang functionality and I could do with some comments on the following. I have the following erlang code that takes a list of tuples and returns a list minus an element if a key is found: delete(Key, Database) -> remove(Database, Key, []). remove([], Key, Acc) -> Acc; remove([H|T], Key, Acc) -> if element(1, H) /= Key -> [H| remove(T, Key, Acc)]; true -> remove(T, Key, Acc) end. Is this a good way of doing this? The if statement seems incorrect. Also is my use of the accumulator Acc making this tail recursive? Cheers Paul

BadAlloc X Error

- by paultop6

Hi Guys, Im having some problems with a GTK program im trying to build. When i compile it i keep getting this error: This probably reflects a bug in the program. The error was 'BadAlloc (insufficient resources for operation)'. (Details: serial 195 error_code 11 request_code 53 minor_code 0) Ive traced it down to the following command that appears to be causing it: gtk_box_pack_start(GTK_BOX (Top_Graph), Widget_Get (Graph_Cpu), TRUE, TRUE, 0); Now Top_Graph and Graph_Cpu are both GtkVbox Widgets. Has anyone ever seen an error like this, and could they give me some advice as to how it is caused Regards Paul

Can EC2 instances be set up to come from different IP ranges?

- by Joshua Frank

I need to run a web crawler and I want to do it from EC2 because I want the HTTP requests to come from different IP ranges so I don't get blocked. So I thought distributing this on EC2 instances might help, but I can't find any information about what the outbound IP range will be. I don't want to go to the trouble of figuring out the extra complexity of EC2 and distributed data, only to find that all the instances use the same address block and I get blocked by the server anyway. NOTE: This isn't for a DoS attack or anything. I'm trying to harvest data for a legitimate business purpose, I'm respecting robots.txt, and I'm only making one request per second, but the host is still shutting me down. Edit: Commenter Paul Dixon suggests that the act of blocking even my modest crawl indicates that the host doesn't want me to crawl them and therefore that I shouldn't do it (even assuming I can work around the blocking). Do people agree with this?
