Formalizing programmers errors

- by Maksee

Every one of us make errors leading to bugs. Once I wanted to start logging my errors for future analysis, probably mentioning project title, approximate time spent and the most important, the type of error. For example when I copy-pasted a fragment about 'x' and replaced every occurrence of 'x' with 'y' and forgot to replace a tiny piece, this goes to 'copy-paste error'. The usefulness of this approach depends on whether I can formalize my errors at all and probably minimizing the number of types to choose from. Otherwise I would start postponing, ignoring and so on so make this system useless. Are there existing research in this area, probably a known minimum set of errors? Maybe some of you already tried to implement something like this and succeeded/failed?

Is this Anti-Scraping technique viable with Crawl-Delay?

- by skibulk

I want to prevent web scrapers from abusing 1,000,000 on my website. I'd like to do this by returning a "503 Service Unavailable" error code for users that access an abnormal number of pages per minute. I don't want search engine spiders to ever receive the error. My inclination is to set a robots.txt crawl-delay which will ensure spiders access a number of pages per minute under my 503 threshold. Is this an appropriate solution? Do all major search engines support the directive? Could it negatively affect SEO? Are there any other solutions or recommendations?

How to Inspect Javascript Object

- by Madhan ayyasamy

You can inspect any JavaScript objects and list them as indented, ordered by levels.It shows you type and property name. If an object property can't be accessed, an error message will be shown.Here the snippets for inspect javascript object.function inspect(obj, maxLevels, level){ var str = '', type, msg; // Start Input Validations // Don't touch, we start iterating at level zero if(level == null) level = 0; // At least you want to show the first level if(maxLevels == null) maxLevels = 1; if(maxLevels < 1) return '<font color="red">Error: Levels number must be > 0</font>'; // We start with a non null object if(obj == null) return '<font color="red">Error: Object <b>NULL</b></font>'; // End Input Validations // Each Iteration must be indented str += '<ul>'; // Start iterations for all objects in obj for(property in obj) { try { // Show "property" and "type property" type = typeof(obj[property]); str += '<li>(' + type + ') ' + property + ( (obj[property]==null)?(': <b>null</b>'):('')) + '</li>'; // We keep iterating if this property is an Object, non null // and we are inside the required number of levels if((type == 'object') && (obj[property] != null) && (level+1 < maxLevels)) str += inspect(obj[property], maxLevels, level+1); } catch(err) { // Is there some properties in obj we can't access?

How to reduce errors in dynamic language such as python, and improve my code quality

- by Martin Luo

I post the origin question in stackoverflow, some people suggest me to post here I've always have trouble with dynamic language like Python. Several problems: Typo error, I can use pylint to reduce some of these errors. But there's still some errors that pylint can not figure out. Object type error, I often forgot what type of the parameter is, int? str? some object? Also, forgot the type of some object in my code. Unit test might help me sometimes, but I'm not always have enough time to do UT. When I need a script to do a small job, the line of code are 100 - 200 lines, not big, but I don't have time to do the unit test, because I need to use the script as soon as possible. So, many errors appear. So, any idea on how to reduce the number of these problems?

GTK applications do not start

- by Greg

Hello, I have a fresh install of Ubuntu 10.04 Server on nodes of a computational cluster, and I access the nodes via ssh. I configured a X server, which I start with the command startx -- -ac. The server is running fine on port :0. Then, I set the environment variable DISPLAY to :0. Now, when I run a GTK application on the node, it fails with the following error: Error: Unable to initialize gtk, is DISPLAY set properly? Now, my question is, is there any runtime library that I need for running GTK applications on top of a X server? I'm probably missing something obvious here, but I can't tell what :P

Folder Permissions for new partition - can't move files

- by user292743

I'm using Ubuntu 14.04. I used the install CD to repartition my HD by resizing /dev/sda1 and creating /dev/sda3 as a Primary Partition. I named it "Media". When I reboot from HD, when I try to move files from the home directory to the new partition, I get an error message "Error while copying. The folder “TV” cannot be copied because you do not have permissions to create it in the destination." The new partition shows up in Gparted as locked, with mount point /media/ian/Media and Label Media. I want to move my media files from the boot partition to a separate partition. Any advice?

NetworkManager not populating resolv.conf

- by Cerin

I recently upgraded from 11.10 to 12.04, and now NetworkManager isn't populating /etc/resolv.conf when connecting to wireless networks, when it had been working perfectly in 11.10. I'm not seeing any explicit errors in either the NM UI or in syslog. How do I diagnose what's wrong? Edit: If I try to run resolvconf, I get the error "resolvconf: Error: /etc/resolv.conf isn't a symlink, not doing anything." What should it be a symlink to and/or how do I get NM to populate it? This says the symlink should point to /run/resolvconf/resolv.conf, but that file does not exist on my system.

install wireshark 1.8.3 in ubuntu 12.04

- by gene

To enable capture traffic on multiple interfaces at once, I tried to install wireshark 1.8.3. However, I encountered the following errors: capture-pcap-util.c:274:1: error: static declaration of ‘pcap_datalink_name_to_val’ follows non-static declaration /usr/local/include/pcap/pcap.h:326:5: note: previous declaration of ‘pcap_datalink_name_to_val’ was here capture-pcap-util.c:289:1: error: static declaration of ‘pcap_datalink_val_to_name’ follows non-static declaration /usr/local/include/pcap/pcap.h:327:13: note: previous declaration of ‘pcap_datalink_val_to_name’ was here After doing some search, I found someone can fix it by reinstall libpcap-dev, or the following commands: step 1:rm & rmdir any file in '/usr/include/pcap';'/usr/local/include/pcap' step 2:Download libpcap by 'sudo apt-get install libpcap0.8-dev' step 3:./autogen.sh in wireshark dir step 4:make clean & make & make install However, neither is working on ubuntu 12.04/wireshark 1.8.3 Anyone can help?

How to add a link group to update-alternatives?

- by Kurtosis

Is it possible to add a custom link group to update-alternatives that is not already there by default? For example, I want to add Scala and all its supporting binaries as a link group 'scala'. I'm trying using this script, but keep getting the error: update-alternatives: error: unknown argument `' I'm not sure what that means, but after troubleshooting the script a bit with no luck, I'm wondering if update-alternatives has a hard-coded list of link groups, that can't be added to, and that doesn't include scala. PS - any chance someone with higher karma can create an update-alternatives tag? Seems this topic gets a decent number of questions, but no tag for it.

Tp_smapi on Thinkpad T440

- by user2597381

I have a Thinkpad T440 with Ubuntu 14.04 (using i3wm). I have had trouble installing tp_smapi. I successfully installed it with dpkg -- can't remember whether I used apt or just downloaded it somewhere -- but I can't load the module. When I use modprobe on tp_smapi, I get this: "modprobe: ERROR: could not insert 'tp_smapi': No such device or address" Note that this is different from the error I get when I mistype the module name. I read somewhere that I might have to rebuild my kernel for it to work, but I'd thought that the kernel I was using (3.13.0-24) had that already set up. Has anyone gotten it to work? I hate how Lenovo manages the batteries!

Uninstalling GRUB from MacBook Air

- by James Brooke

So... I have a MacBook Air and I recently tried to install Ubuntu on my external HD. I booted Ubuntu from a flash drive and everything had gone fine. I turned off my computer and when I turned it on again I got a message of error and a "grub rescue" line to enter some code. I rebooted holding the "option" key and I selected the Mac partition and everything is fine with my system, but every time I start my system and I don't hold the "option" key, I get the same error and the grub rescue message. I just want things to go back to normal, as they were before I installed Ubuntu on my external HD (which, btw, presented a message that said there was no boot loader). What do I do?

IDirect3DDevice9Ex and D3DPOOL_MANAGED?

- by bluescrn

So I wanted to switch to IDirect3DDevice9Ex, purely for the SetFrameLatency function, as fullscreen vsynced D3D seemed to produce noticable input lag. But then it tells me 'ha ha ha! now you can't use D3DPOOL_MANAGED!': Direct3D9: (ERROR) :D3DPOOL_MANAGED is not valid with IDirect3DDevice9Ex Is this really as unpleasant as it looks (when you're relying quite heavily on managed resources) - or is there a simple solution? If it really does mean manual management of everything (reloading all static textures, VBs, and IBs on a device reset), is it worth the hassle, will IDirect3DDevice9Ex bring enough benefit to make it worth writing a new resource manager? Starting to think I must be doing something wrong, due to this: Direct3D9: (ERROR) :Lock is not supported for textures allocated with POOL_DEFAULT unless they are marked D3DUSAGE_DYNAMIC. So if I put my (static) textures in POOL_DEFAULT, they need flagging as D3DUSAGE_DYNAMIC, just because I lock them once to load the data in?

Can't get Optimus to work with Ironhide on an Asus N53SN

- by Musaab

I installed Ubuntu 11.10 (Same issue in 11.04 btw) and then I installed Ironhide. I went through the configuration, chose the one with the highest confirmation for my system and tested it: > Error: Module nvidia does not exist in /proc/modules > P50 Disabling nVidia Card Succeded (the spelling error is theirs) And it changes nothing. I tried other configurations and got worse results. This has really become a major headache. Any solutions?

Ubuntu gone out of order - Wont install any packages. What do I do?

- by Aborted

Lately, I've been getting some strange behaviour from Ubuntu. First and the most important is that it wont install updates. It gives a package installation error and it simply wont work. Earlier I tried to install TeamViewer via the Software Center, but got the same package error. I also feel like the connection speed is going slower than it should - don't know if this one is relevant to this case. What's wrong with my installation? How do I fix these package installation errors?

Where would a spam bot be located?

I have a hosted website using a free hosting service, I received an email this afternoon saying that I have been suspended because my account has been compromised. Basically, someone is using my email account to mass send spam. I've changed all the passwords and everything but when my Gmail pulls the emails from the host it's still downloading loads of spam messages that show like this: This message was created automatically by mail delivery software.

sbackup: can not mount FTP automatically

In the sbackup configuration GUI i set the ftp://user:pw@online/storage and it's marked as successfully connected. After daily backup time, I checked the ftp and it was empty.

How to save this permanently?

Is it bad practice to output from within a function?

For example, should I be doing something like: <?php function output_message($message,$type='success') { ?> <p class="<?php echo $type; ?>"><?php echo $message; ?></p> <?php } output_message('There were some errors processing your request','error'); ?> or <?php function output_message($message,$type='success') { ob_start(); ?> <p class="<?php echo $type; ?>"><?php echo $message; ?></p> <?php return ob_get_clean(); } echo output_message('There were some errors processing your request','error'); ?> I understand they both achieve the same end result, but are there benefits doing one way over the other? Or does it not even matter?

Inkscape won't open .cdr files

Hello I'm running Kubuntu 12.04 and I've installed Inkscape because I need to edit a .cdr file, Inkscape works like normal but the sole task I need it to do is edit said .cdr file which I understand it should be capable off by default. Whenever I try to open the file though I get the following error: UniConvertor failed: The eror itself is longer but what it seems to be saying that it can't find this application, and I myself haven't found it in the package manager. If someone has experienced something similar or has a simple solution for editing cdr's I'm no artist I just need to change some names, I would be very gratefull. The full error.

ISTQB terminology question (Defect)

- by user970696

According to ISTQB (and few more sources + wiki ), a defect/bug is the actual cause of error in software, e.g. incorrect statement, logical or semantic error. The actual definion is: a flaw in the system or component that could lead to the failure. But what about specification bugs? I cannot relate to it. Specification bugs are quite common but if the programmer implements software according to spec with a bug, it is not his fault (IMHO). But then the definion could not apply and I am sure it must have been addressed somehow. Could you help me to understand this?
