• Should I understand SVN before I jump to GIT?

  - by John Isaacks

  I work in a department where no one has ever used source control before, including myself. I am trying to push the concept. I have spent a little while researching SVN. I some basics learned. I can Create/update/checkout/commit with command line and from Tortoise. I am starting to learn how to tag and branch but still confused a lot about conflicts between branches and trunk etc. I am still learning, but I do not have a physical person who can show me anything. Its all from books/tutorials and trial and error. From what I have read online it seems like git is the better thing to know, but its also more complicated. I don't want to overwhelm myself. Should I continue to master svn before moving to git or would I be wiser to just jump to git now? Are there pros and cons to both approaches?

• How to balance programming projects between feasibility and usefulness

  - by tyjkenn

  I've become fairly competent as a programmer, but I would not say I am a master. I work independently, most as a hobby, although I have done some freelance PHP work. I tend to find myself dabbling in a lot of things: Java Android SDK, Arduino, game scripting, Lua, etc. I've reached the point where I want to start a real software project, but cannot think of a small enough project that allows me enough practice, while still being able to publish a decent piece of software in a reasonable amount of time, and build up a portfolio. More specifically, I was looking at Ubuntu development, in Python, using the Quickly toolset, which includes the PyGTK libraries. So the question is, what is the best way to come up with a small project that is still useful, as a starting point to a software development career?

• Who created that user?

  - by AaronBertrand

  Twitter has provided some great fodder for blog content lately. And twice this week, I've found an excuse to take advantage of the default trace. Tonight @meltondba asked: I'm trying to find who created a user act in a DB It is true, SQL Server doesn't really keep track of who created objects, such as user accounts in a database. You can get some of this information from the default trace, though, since it tracks EventClass 109 (Audit Add DB User). If you run this code: USE [master] ; GO CREATE LOGIN...(read more)

• Making bash script to check connectivity and change connection if necessary. Help me improve it?

  - by cypherpunks

  My connection is flaky, however I have a backup one. I made some bash script to check for connectivity and change connection if the present one is dead. Please help me improve them. The scripts almost works, except for not waiting long enough to receive an IP (it cycles to next step in the until loop too quick). Here goes: #!/bin/bash # Invoke this script with paths to your connection specific scripts, for example # ./gotnet.sh ./connection.sh ./connection2.sh until [ -z "$1" ] # Try different connections until we are online... do if eval "ping -c 1 google.com" then echo "we are online!" && break else $1 # Runs (next) connection-script. echo fi shift done echo # Extra line feed. exit 0 And here is an example of the slave scripts: #!/bin/bash ifconfig wlan0 down ifconfig wlan0 up iwconfig wlan0 key 1234567890 iwconfig wlan0 essid example sleep 1 dhclient -1 -nw wlan0 sleep 3 exit 0

• how to write T-SQL to compare and copy data?

  - by George2

  Hello everyone, I have two SQL Server 2008 Enterprise databases (on two machines), and one of the databases is master database and another database is slave database. I want to transfer update from a table in source database to a table in destination database (two tables are of the same schema, both of them are using a single column as unique primary key). The transfer rule is (in short, the rule is keeping the destination database the same as source database because of the update of the source database), if there is a new row in source database but not in destination database, insert the row in destination database; if a row not exists in source database but exists in destination database, delete the row in destination database; if a row's content (i.e. columns other than primary key columns) changes in source database, update the new content into destination database. thanks in advance, George

The documentation for my webapp reads as follows: you will need to create following cronjob: /public_html/cake/console/cake -app /public_html/app master Also, I want any output written to a log file.

• Why are the proposed BADSIG (on apt-get update) fixes secure?

  - by EvanED

  I'm running apt-get update, and I see errors like W: GPG error: http://us.archive.ubuntu.com precise Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <[email protected]> It's not hard to find instructions on how to fix these problems, for instance by asking for the new keys with apt-key adv --recv-keys or rebuilding the cache; so I'm not asking about how to fix these. But why is this the right thing to do? Why is "oh, I need new keys? Cool, go get new keys" not just defeating the purpose of having a signed repository in the first place? Are the keys signed by a master key that apt-key checks? Should we be doing some additional validation to ensure that we're getting legitimate keys?

• Certain Keyboard shortcuts not working

  - by user968808

  I have the logitech k800 keyboard but can't seem to get certain shortcuts working. I change in the keyboard shortcut settings volume up and down and it actually takes the key assignment but does not take effect when trying to use. After trying for a while I also tried to create a custom shortcut after with the command amixer -q sset Master 10%- Finally I tried changing the command to touch a file to see if it is actually responding but nothing. How can it take the key as an assignment in the shortcut settings but not to actually respond when pressing it. FYI other keys work like mute, next track etc. There is just 3 keys shortcuts not currently working. Thanks

• Credit Card Payment Processing which APIs do you use?

  - by user3330840

  It's for a Point of Sale Terminal where the customer will bring the physical credit card and it will be swiped through the terminal. The business has a merchant account on some banks. So, how do I start accepting credit cards in my app? The credit cards that needs to be accepted include: visa, master-card, amex, discover. Which APIs do I need to use? The programming language doesn't matter it can be in any programming languages Java/C#/C++/Python or anything. Will there be a single API or multiple APIs that need to be integrated? (I know some about PCI compliance and security encryption)

• Google Analytics: Track user usage and flow

  - by Quintin Par

  Can someone help to query Google analytics to track a specific user behavior and usage pattern? Currently I pass user id’s to GA as _setCustomVar(2, 'id', id, 1); This is session based. But I am yet to master how I can utilize this to view usage pattern & behavior for the passed id. Say, I need to understand the visualization flow for one id or the page view count for that id etc Rephrasing, can I filter all existing reports for a specific id that I can select?

• Multiple style sheets best practice

  - by user1145927

  I currently am working on a project which has one large style sheet for about 20 pages. The style sheet contains some styles which are specific for certain pages. I'd like to break the style sheet up so there is one style sheet for each page with one master style sheet that handles everything generic. The reason I want to do this is so people can work on multiple pages without having to worry about who has that large style sheet checked out (I'm using TFS). Is this good practice?

• What is the good way of sharing specific data between ViewModels

  - by voroninp

  We have IAppContext which is injected into ViewModel. This service contains shared data: global filters and other application wide properties. But there are cases when data is very specific. For example one VM implements Master and the second one - Details of selected tree item. Thus DetailsVm must know about the selected item and its changes. We can store this information either in IAppContext or inside each concerned VM. In both cases update notifications are sent via Messenger. I see pros and cons for any of the approaches and can not decide which one is better. 1st: + explicitly exposed shared proerties, easy to follow dependencies - IAppContxt becomes cluttered with very specific data. 2nd: the exact opposite of the first and more memory load due to data duplication. May be someone can offer design alternatives or tell that one of the variants is objectively superior to the other cause I miss something important?

• How can I kill MySQL queries every 60 seconds in Windows?

  - by Ethan Allen

  I want to check my MySQL server every minute and kill queries that have run longer than 150 seconds. The main reason I want to do this is because I don't want queries from certain people to lock up the DB for everyone else. I know this is not the ultimate solution to the problem, but at least it's a fallback in case something goes wrong with a query. I don't have a slave DB (this is just an at-home project). I'd like to schedule a script to run that does this for me. I'm unfamiliar with Perl or Ruby and I need it done on my Windows 2008 Server box. I've looked into creating a simple cmd line script, but that doesn't seem to be possible. I know currently I can do something like this but I have to do it manually: mysqladmin processlist mysqladmin kill Anyone have any ideas or examples on how I could do this?

• Help deciding on an area of study for a PhD [closed]

  - by ale

  I am going to start a PhD in about 1 year. My undergraduate degree is in computer science and my master's is in artificial intelligence. I want to get ideas about what's going to be hot in say 5 years i.e. what could I spend 3-4 years studying to potentially have expertise that will be applicable to industry and the computing world ? Impossible to answer factually but some ideas and thoughts would be great. I have narrowed my ideas down to AI (yes, even more AI) and information security. AI seems to becoming popular again but security is always a going to be useful. From a career point of view, if I were to stay working in software development then this might actually be the best move but I've always wanted to do a PhD! Many thanks :).

• Check for Instant File Initialization

  Instant File initialization, IFI, is generally a good thing to have. Check out this earlier blog post of mine f you don't know what IFI is and why it is a good thing: blog . The purpose of this blog post is to provide a simple script you can use to check if you have IFI turned on. Note that the script below uses undocumented commands, and might take a while if you have a large errorlog file...

• CPU spikes cause audio stuttering in Audacious when browsing? (Lubuntu)

  - by Alucai Vivorvel

  My default audio player is Audacious, browser Google Chrome. I tried Firefox, and while I love it, the CPU load spikes when doing something as simple and small and switching a tab, which causes the audio playing to stutter (as sound is onboard and handled thru the CPU). Chrome doesn't do this as much, but there is the occasional stuttering when browsing, which is ridiculous, as not even Windows Vista does this. So I thought maybe it's something to do with how Lubuntu handles sound, I checked and only ALSA was installed. I tried installing PulseAudio, but, while the music "plays", nothing comes through the speakers. Immediately after switching back to ALSA the music pours out of them. So I was wondering if you had any idea what was going on here. I asked on Ubuntu Forums but apparently my problem is too complex, as it's been over a week since the last reply. Specs are: AMD Athlon 64 3200+ @ 2GHz 2GB Corsair 667MHz DDR2 RAM ATi HD Radeon 3650 (AGP) 512MB 500W Cooler Master PSU 80GB SATA II HDD (Vista is installed on 500GB drive) Biostar K8M800 Motherboard

• Do any database "styles" use discrete files for their tables?

  - by Brad

  I've been talking to some people at work who believe some versions of a database store their data in discrete tables. That is to say you might open up a folder and see one file for each table in the database then several other supporting files. They do not have a lot of experience with databases but I have only been working with them for a little over a half year so I am not a canonical source of info either. I've been touting the benefits of SQL Server over Access (and before this, Access over Excel. Great strides have been made :) ). But, other people were of the impression that the/one of the the benefit(s) of using SQL Server over Access was that all the data was not consolidated down into one file. Yet, SQL Server packs everything into a single .mdf file (plus the log file). My question is, is there an RDBMS which holds it's data in multiple discrete files instead of one master file? And if the answer is yes, why do it one way over the other?

• What to bring to a programming interview? [closed]

  - by ddrum

  I have just completed my Master's degree in Computer Science and have gotten my first job interview as a developer. I do not have much experience in large scale development projects, but I am hoping my university education counts for something. I am wondering, what materials should I bring that would impress my interviewers? What do most interviewers expect, especially from a new graduate? **Edit: The job interview went OK, except I forgot my pants. Thanks for all the great advice!
