• How could there still not be a mysqldb module for Python 3? [closed]

  - by itsadok

  This SO question is now more than two years old. MySQL is an incredibly popular database engine, Python is an incredibly popular programming language, and Python 3 has been officially released two years ago, and was available even before that. What's more, the whole mysqldb module is just a layer translating Python's db-api to MySQL's API. It's not that big of a library. I must be missing something here. How come almost* nobody in the entire open source community has spent the (I'm guessing) two weeks it takes to port this lib? Is Python 3 that unpopular? Is the combination of python and mysql not as common as I assume? Or maybe it's just a lot harder to port mysqldb than I assume? Anyone know the inside story on this? * Now I see that this guy has done it, which takes some of the wind out of my question, but it still seems to little and too late to make sense. EDIT: OK, I'm aware that the stock answers for these kind of questions cover this one as well. Patches welcome, scratch your itch, we don't work for you and we don't have the time, etc. I actually took a shot at porting this about a year ago, but it was my first time doing anything with Python C extensions, and I failed. My point in writing this was not a plea for somebody to write it, but genuine curiosity: it seems that some much more complicated libraries have been ported to python 3 already, and in the poll for which libraries should be ported, mysqldb is not even nominated! That suggests that maybe (2) is the right answer. UPDATE: I found that there are several new libraries that provide mysql support under Python 3, I just wasn't googling hard enough. That explains everything.

• Ubuntu cannot see Windows 7 partitions on install

  - by Nash0

  I've been trying to install Ubuntu 10.10 as a dual boot with Windows 7 on my Dell latitude e6510. It is currently running Windows 7 and I have used the MS disk tools to shrink the Win 7 NTFS partition to make room for Linux. The issue I'm having is that when I run Ubuntus installer by booting from CD it sees the entire hard drive as unallocated space. I have also tried Kbuntu 10.10, Fedora 14, booting a Gparted 0.8.0 usb drive, and Ubuntu "install in Windows" with wubi they all have problems. EDIT: When I run the "try Ubuntu" option on booting from cd it can mount my Windows partition and I can view the files. The output of sudo parted -l when running in try Ubuntu mode: Warning: /dev/sda contains GPT signatures, indicating that it has a GPT table. However, it does not have a valid fake msdos partition table, as it should. Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table? Yes/No? yes Model: ATA ST9500420AS (scsi) Disk /dev/sda: 500GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0 has been opened read-only.

• Windows, Apache and MSSQL Authentication

  - by user1114330

  I have a create database script written in perl. I remember it working just fine another machine. A couple years later using a Vista machine I am trying to use it again and it keeps failing. The main difference is that now I am using Apache instead of IIS. In the script the IUSR account is granted permissions as it needs to write to the database as a part of another program. IIS has been uninstalled on this machine but the IUSR account still exists. The NT AUTHORITY\IUSR is also seen in the logins drop down in MSSQL(2012). The machine is running Vista Home Edition. However when running the script I get errors that say that NT AUTHORITY\IUSR cannot be found. I tried also with COMPUTERNAME\IUSR just for the heck of it and of course it was not found. I also tried with IUSR alone and for some reason the user isn't being "found"? Any ideas?

• Batch file to open multiple cmd prompts

  - by JHarris

  I am trying to write a batch file that will automate the following manual process: Open a new cmd prompt (prompt1) Run a bat file (b1) Run a program (that will continue to run) Minimize prompt1 Open a new cmd prompt (prompt2) Run a bat file (b1) Run a different program (that will continue to run) Minimize prompt2 I've found ways to open multiple instances of cmd to run different things, but after I've run the first thing (b1), I then need to run a program in that same cmd window. I currently have start /min cmd /k C:\Users\db2admin\python_environment\Scripts\activate.bat start /min cmd /k C:\Users\db2admin\python_environment\Scripts\activate.bat This opens the two windows and runs the bat, great, but now I need to execute another command (running a python file) in each of the cmd windows. How do I send commands to each prompt?

• AWS EC2: how to compute the cost

  - by EsseTi

  i'm new to AWS, i'm using the free right not and it's terrific. Now, in 1yr the free expires. i went to the website http://aws.amazon.com/ec2/pricing/ where the pricing is but i didn't really get how to compute it. The price are in $ per Hours but i don't think that this means, if i need to have my application running 24h/365d i've to multiplay it for 8760, or do i have? because they write about usage, but how do i compute this value? if i've a website where people in total spend smt like 10 minutes a month and 1 where people spend 750hour a months i pay the same? i can't believe that is the same price. PS:if i've a scheduled task, does it affect the usage?

• Artists and music - Need Help Deciding on a CMS

  - by infty

  A friend has asked me to build a site with the following options: staff members must be able to add new music and artists to the page a gallery must be provided - it is also good if each artist has the ability to have his/her own smaller gallery users must be able to vote for artists users must be able to alter in discussions (forums or comments sections) staff members must be able to blog staff members must be able to write articles I did a small project where i actually implemented all of these features, but I want to use an existing content management system for all of these features so that future developers can, hopefully, more easy extend the website. And also, so that I don't have to provide too much documentation. I have never developed a website using an external CMS like Drupal or Wordpress and after seeing hours of tutorial videos of both systems, I still can't make up my mind on whether i should : a) use Drupal 7 b) use Wordpress 3 c) create my own cms I can imagine that staff members would also want to create content using iPhone or android based mobile devices, but this is not a required feature. Can someone, with experience, please tell me about their experiences with larger projects like this? The site will have approximately 400 000 - 500 000 visitors (not daily visitors, based on numbers from last year in a period of 4 months)

• Specific cron at time point [closed]

  - by ARTI

  I have a very specific task, but can't handle it. I am not a programmer and totally n00b on bash scritps. So the question is, how to create a cron job like this: Script A.sh could be called at any time by hands, and it should create cron job to run script B.sh once at the nearest time point. For example I will have 4 time points: 10.00pm, 10.15pm, 10.30pm, 10.45pm. So if trigger a script A.sh at 10.07pm it should creat cron job to run ONCE script B.sh at 10.15h, because 10.15h is the nearest time point in future. Is it possible? How can I write such script A.sh? I use Centos 6 It is very important and urgent for me. Thank you very much.

• Verify linux user passwords

  - by zero_r

  Hi there I got a linux server that has several dozen users. I also have the cleartext password for every user (i know - bad security). I would like to know if the passwords are correct. Since the users are all ftp users and have the nologin shell, I cannot just write a script to check if login works. How can I do a local check on passwords? Script output could look like this: $ check_userpw < user_pw_list.txt user1 ok user2 ok user3 mismatch! user4 ok Thanks

• Why does this PowerShell script hang?

  - by jshin47

  Today I had to use Start-Sleep many times so I thought I would create a shortcut function for it, sleep($time). However, whenever I entered the function it never exits! It must be an issue with either the data type for the argument for Start-Sleep or the way I am declaring the function. Instead of posting the whole script, I've posted this useless one that would make a familiar beep pattern if it worked: function beep { Write-Host `a } function sleep { param([int]$time) Start-Sleep -m $time } beep sleep(300) beep sleep(200) beep sleep(50) beep sleep(300) beep sleep(450) beep sleep(200) beep

• puppet onlyif specified nodes

  - by Valintinr

  I'm trying to write a puppet template. I have a puppet-master and a few puppet-agents and they all must be divided. I think it's good to do this by the node's hostname. But when I tried to do this I've encountered an error "puppet-agent[169037]: (/Stage[main]//Exec[adduser]) Could not evaluate: Could not find command 'ru1'" see code below exec { 'adduser': command => 'sudo adduser -m -p pawSfQewWrUAA test -G wheel', path => [ '/bin','/usr/bin' ], onlyif => "$hostname == ru1" } I need to specify this task for only one node with the hostname ru1. So have can I do this? Thanks.

• How to use ccache selectively?

  - by Anonymous

  I have to compile multiple versions of an app written in C++ and I think to use ccache for speeding up the process. ccache howtos have examples which suggest to create symlinks named gcc, g++ etc and make sure they appear in PATH before the original gcc binaries, so ccache is used instead. So far so good, but I'd like to use ccache only when compiling this particular app, not always. Of course, I can write a shell script that will try to create these symlinks every time I want to compile the app and will delete them when the app is compiled. But this looks like filesystem abuse to me. Are there better ways to use ccache selectively, not always? For compilation of a single source code file, I could just manually call ccache instead of gcc and be done, but I have to deal with a complex app that uses an automated build system for multiple source code files.

• batch file to disable network share on Windows XP

  - by Robb

  Loosely related to this question Network Share causing Cygwin to run slowly after 'ls', I'd like to write a little batch file that I can execute to disconnect the host from any network shares and subsequently another batch file to reconnect. Ideally, this would be something that I can execute from a PuTTY terminal, SSHed into the box running cygwin. I'm pretty sure the batch files can be written easily, but I don't know about executing them from a PuTTY terminal. Regardless, I'd still like the batchfiles anyways. For the sake of simplicity my process would be: Log into server via PuTTY Run batch files to disconnect shares Do what I need to do Run batch files to reconnect shares Exit session, closing PuTTY

I have Samba set up so Windows can access the drives. here is the last bit of my /etc/samba/smb.conf [personeel] path = /media/windows browsable = yes guest ok = yes writable = yes read only = no create mask = 0775 directory mask = 0775 I want the directory to be shared with writable permissions to everyone who can access the Ubuntu Server. I have tried sudo chmod but to no success. Any help would be appreciated

• Missing files when Windows 7 returns from hibernate w/ dual boot

  - by Arthur N

  I have a dual-boot setup with Ubuntu (lucid) and Windows 7. I have the Windows file system shared on Ubuntu through Samba. Occasionally, I am working on Windows and my machine will go into hibernate (i.e. when the battery level is critical). By default, my GRUB settings boot me into Ubuntu. So when I get back to my PC, sometimes I just hop into Ubuntu instead of going back to Windows. However, if I write any files to the Windows file system during that Ubuntu session, the next time I do go back to Windows (which resumes from hibernate), those files are missing. Obviously, the state of the actual file system and the hibernate snapshot become out of sync, and Windows chooses the hibernate snapshot, overriding any changes I may have made thru Ubuntu. For now, I've disabled the hibernate option in the Windows power settings, but is there any utility I can use to get back some of those missing files?

• Is this a good implementation of a loop in Prolog?

  - by Carles Araguz

  First of all, let me tell you that this happens to be the first time I ask something here, so if it's not the right place to do so, please forgive me. I'm developing a rather complex software that has a Prolog core implementing a FSM. Since I don't want it to stop (ever), I'm trying to write a good loop-like predicate that would work using Prolog's recursion. After a few unsuccessful tries (mainly because of stack problems) I ended up having something similar to this: /* Finite State Transition Network */ transition(st0,evnt0,st1). transition(st1,evnt1,st2). transition(st2,evnt2,st0). fsm_state(state(st0),system(Energy,ActivePayloads),[]) :- /* ... */ transition(st0,evnt0,NextState), !, fsm_state(state(NextState),system(Energy,ActivePayloads),[]). fsm_state(state(st1),system(Energy,ActivePayloads),[]) :- /* ... */ transition(st1,evnt1,NextState), !, fsm_state(state(NextState),system(Energy,ActivePayloads),[0,1,2]). fsm_state(state(st2),system(Energy,ActivePayloads),[P|Params]) :- /* ... */ transition(st2,evnt2,NextState), !, fsm_state(state(NextState),system(Energy,ActivePayloads),[]). start :- Sys = system(10,[]), fsm_state(state(s0),Sys,[]). Is this a good approach?

• What makes you look like a bad developer (ie a hacker) [on hold]

  - by user134583

  This comes from a lot of people about me, so I have to look at myself. So I would wonder what make one a bad developer (ie a hacker). These are a few things about me I used IDE intensively, all features, you name it: auto-completion, refactoring, quick fixes, open type, view hierarchy, API documentation, etcc When I deal with writing code for a project in domain I am not used to (I can't have fluency in this, this is new), I only have a very rough high level ideas. I don't use the standard modeling diagrams for early detail planning. Unorthodox diagrams that I invented when I need to draw the design in details. I don't use UML or similar, I find them not enough. I divide the sorts of diagram I drew into 3 types. Very high level diagrams which probably can be understood by almost anybody. Data entity diagram used for modeling data objects only (like ER diagrams and tree for inheritances and composition). Action diagrams for agents/classes and their interactions on data objects they contain. Constantly changing the interface (public methods) between interacting agents/classes if the need arises. I am more refrained when the interface and the module have matured Write initial concept code in a quick hackie way just so that the module works in the general cases so that I can play around with it. The module will be re-factored intensively after playing around so I could see more corner cases that I couldn't or (wouldn't want) anticipate before writing code. Using JUnit for integration-like test by using TestSuite class and ordering Unit test classes in the suite Using debugger almost anytime there is a problem instead of reading the code Constantly search on the internet for how to do some thing with some library that I haven't used a lot. So judgment, am I a bad developer? a hacker? Put in other words, to make sure this is not considered off-topic: - Is this bad practice to make your code too agile during incubating/prototyping phase of software development - Is it bad practice to use JUnit for integration testing, (I know there are other framework for integration testing, but those frameworks are for a specific products, not general)

• Slot load DVD burner options for standard desktop case

  - by Michael Kohne

  I need a new DVD burner (internal) for my father-in-law's computer. He's apparently broken the current one - he forgot to push the tray back in after doing something and hit it with his chair. Given this, I'd like to get him a slot-loading DVD burner, so as to avoid the problem entirely. I need an internal device, and I'll be mounting in a 5 1/4" bay. He doesn't need any super-spec device - as long as it can read/write all the standard formats, it's good. I see a few options at newegg.com, but they all have mixed reviews. Are there any out there that are generally seen as reliable? How does one go about mounting slimline devices in a standard 5 1/4" bay? Is there a standard faceplate kit for that?

• Is there a better way to organize my module tests that avoids an explosion of new source files?

  - by luser droog

  I've got a neat (so I thought) way of having each of my modules produce a unit-test executable if compiled with the -DTESTMODULE flag. This flag guards a main() function that can access all static data and functions in the module, without #including a C file. From the README: -- Modules -- The various modules were written and tested separately before being coupled together to achieve the necessary basic functionality. Each module retains its unit-test, its main() function, guarded by #ifdef TESTMODULE. `make test` will compile and execute all the unit tests, producing copious output, but importantly exitting with an appropriate success or failure code, so the `make test` command will fail if any of the tests fail. Module TOC __________ test obj src header structures CONSTANTS ---- --- --- --- -------------------- m m.o m.c m.h mfile mtab TABSZ s s.o s.c s.h stack STACKSEGSZ v v.o v.c v.h saverec_ f.o f.c f.h file ob ob.o ob.c ob.h object ar ar.o ar.c ar.h array st st.o st.c st.h string di di.o di.c di.h dichead dictionary nm nm.o nm.c nm.h name gc gc.o gc.c gc.h garbage collector itp itp.c itp.h context osunix.o osunix.c osunix.h unix-dependent functions It's compile by a tricky bit of makefile, m:m.c ob.h ob.o err.o $(CORE) itp.o $(OP) cc $(CFLAGS) -DTESTMODULE $(LDLIBS) -o $@ $< err.o ob.o s.o ar.o st.o v.o di.o gc.o nm.o itp.o $(OP) f.o where the module is compiled with its own C file plus every other object file except itself. But it's creating difficulties for the kindly programmer who offered to write the Autotools files for me. So the obvious way to make it "less weird" would be to bust-out all the main functions into separate source files. But, but ... Do I gotta?

• Scroll bar for vim(curses-based one, not gvim)?

  - by xiaq

  As a Linux user, I have been quite comfortable with CLI and TUI tools, but I miss the little scrollbar present in almost every GUI program. It has always been easier for me to know how long the file is and where I am from the scrollbar instead of "9752 lines, 24%". What I expect is a ASCII scrollbar that looks like | | | | # # # | | | and I can configure to appear on the left or right (and if on the left, the relative position to line numbers and fold marks). Is there already a Vim plugin to do this, or how can I write my own one? Vim's plugin framework doesn't seem to support such UI modifications directly.

• Use the &ldquo;using&rdquo; statement on objects that implement the IDisposable Interface

  - by mbcrump

  From MSDN : C#, through the .NET Framework common language runtime (CLR), automatically releases the memory used to store objects that are no longer required. The release of memory is non-deterministic; memory is released whenever the CLR decides to perform garbage collection. However, it is usually best to release limited resources such as file handles and network connections as quickly as possible. The using statement allows the programmer to specify when objects that use resources should release them. The object provided to the using statement must implement the IDisposable interface. This interface provides the Dispose method, which should release the object's resources. In my quest to write better, more efficient code I ran across the “using” statement. Microsoft recommends that we specify when to release objects. In other words, if you use the “using” statement this tells .NET to release the object specified in the using block once it is no longer needed.   So Using this block: private static string ReadConfig()         {             const string path = @"C:\SomeApp.config.xml";               using (StreamReader reader = File.OpenText(path))             {                 return reader.ReadToEnd();             }         }   The compiler converts this to: private static string ReadConfig1() {     StreamReader sr = new StreamReader(@"C:\SomeApp.config.xml");       try     {         return sr.ReadToEnd();     }     finally     {         if (sr != null)             ((IDisposable)sr).Dispose();     }   }

• IEEE SRS documents: lightweight version when working with outside contractors?

  - by maple_shaft

  Typically we follow an Agile development process that tends not to put an emphasis on writing requirements and technical documents that nobody will read. We tend to focus our limited manpower to development and testing activities with collaborative design and whiteboarding as a key focus. There is a mostly standalone web component that will take quite a few weeks to develop, but this work can be mostly parallel with other project work going on. To try and catch up time I was given a budget for hiring a developer on oDesk to complete this work. While my team isn't accustomed to working off of a firm SRS document, I realize that with outsourced development that it is a good idea to be as firm and specific as possible so I realize that I need to provide a detailed Requirements and Technical Specification document for this work to be done correctly. When I do write a Requirements document I typically utilize the standard IEEE SRS document template but I think this is too verbose and probably overkill for what I need to communicate to a developer. Is there another requirements document that is more lightweight and also accepted by a major standards organization like the IEEE? Further, as what will be developed as a software module that will interact with other software modules, my requirements really need to delve into technical specifications for things to work correctly. In this scenario does it make sense to merge technical and requirements specifications into a single document, and if not, what is a viable alternative?

• Help with Abstract Factory Pattern

  - by brazc0re

  I need help with a abstract factory pattern design. This question is a continuation of: Design help with parallel process I am really confused where I should be initializing all of the settings for each type of medium (ex: RS232, TCP/IP, etc). Attached is the drawing on how I am setting up the pattern: As shown, when a medium is created, each medium imposes a ICreateMedium interface. I would assume that the Create() method also create the proper object, such as SerialPort serialPort = new SerialPort("COM1", baud); however, TCPIPMedium would have an issue with the interface because it wouldn't need to initialize a serial port object. I know I am doing something majorly wrong here. I just can't figure it out and have been stuck for a while. What I also get confused on show the interface IMedium will get access to the communication object once it is created so it can write out the appropriate byte[] packet. Any guidance would be greatly appreciated. My main goal is to have the Communicator class spit a packet out without caring which type of medium is active.

• Does it make a difference to read from a file instead of from MySQL?

  - by Joe Huang

  My web server currently is quite loaded. And I have a PHP file that is accessed very often remotely. The PHP file basically makes a MySQL query and returns a JSON formatted string. I am thinking to use a Cron job to write the necessary data into a file every 15 mins, so the PHP file doesn't make a MySQL query, instead it reads from the file. Does it make a difference? I mean to alleviate the server loading (CPU/MySQL) a bit?
