• Tried teaching myself to program before college, accidently overwhelmed myself, tips?

  - by Gunnar Keith

  I'm sixteen, I'm overly interested in programming, and I'm currently taking IT classes during my mornings in high school. Last year, I tried teaching myself to code. It was quite exciting, but all I did was watch TheNewBoston's videos on YouTube for Python. After his tutorials, I just did research, made some CMD programs, and that's it. After that, I got cocky and got my feet wet in many other languages. Java, C++, C#, Perl, Ruby... and it overwhelmed me. Which made it less fun to code. I want to go to college for a 2 year programming course. And I want to make writing code my profession. But how do you recommend I attack re-learning it all again? Start with Python? Don't even try? Also, I'm not 100% in math, but I'm good friends with a lot of programmers, who say they suck at math, but manage to code just fine. I'm not looking for negative feedback. I just want the proper head-start on things before college.

• Is there a preferred way to set up a virtual Ubuntu server on a desktop?

  - by Keith Groben

  I love Ubuntu, and as I am searching the internet, I am finding that some questions I have have not been answered yet. One of them is if there is a preferred way to set up a virtual server. I look through the Ubuntu Software Center, but found nothing from the search "Virtual Server" I then searched the internet and found lots of posts to trouble-shoot VMWare virtual servers. So, like a good researcher I looked in the Software center for VMWare. Sure enough I found "user agent" and "view open client". I didn't get sufficient info from the software center. And searching the website only left me scratching my head. I want to install Ubuntu Server Edition. I already have a server, but am cautious "trying out" things on it. So a virtual server sounds like what I need.

• ".ts " files not recognised

  - by Keith Gardner

  I have some .ts files (programs recorded from my Sharp TV on USB stick) that I want to store/play on my PC. However, although they are listed on the stick when its plugged in the PC nothing will recognize the files. I have tried VLC (the "slider" moves but there's no sound or video) and changed the extension to MPEG, MP2, etc. but no joy. I have tried converting the files with file converters and demuxers but none of these recognize the files. Are the files corrupted (they play on the TV) or do Sharp have a unique file structure? Any help would be greatly appreciated.

• Proper response for a REST insert - full new record, or just the record id value?

  - by Keith Palmer

  I'm building a REST API which allows inserts (POST, not idempotent) and updates (PUT, idempotent) requests to add/update database to our application. I'm wondering if there are any standards or best practices regarding what data we send back to the client in the response for a POST (insert) operation. We need to send back at least a record ID value (e.g. your new record is record #1234). Should we respond with the full object? (e.g. essentially the same response they'd get back from a "GET /object_type/1234" request) Should we respond with only the new ID value? (e.g. "{ id: 1234 }", which means that if they want to fetch the whole record they need to do an additional HTTP GET request to grab the full record) A redirect header pointing them to the URL for the full object? Something else entirely?

• Change screen resolution from terminal

  - by Keith

  When I enabled my Nvidia graphics card, it changed the resolution of my screen to larger than my screen. As the result I cannot access any functions that were previously on the right side of my screen. How do I undo this? I originally had 8.04 and was able to change the resolution to whatever I wanted. I'm a new user and can copy and paste commands from a post to terminal mode but that's about it. I have no idea what they are or what they mean.

• Should I charge for travel time as a contractor?

  - by Keith

  Here's a question for all my fellow contractors - I'm paid quite handsomely for my normal contracted hours (any overtime is billed at the same rate) but do you think it fair to bill for travel time to the other end of the country (regional office) when this takes place outside of the normal working day (or overlapping into the evening) as well as actual time holed up in a hotel room when you get there, ready for a normal working day the next day, along with the return journey? Petrol is claimed normally (nominal rate) and hotel is covered by the company I contract for.

• Recommend hosting with fast MySQL database please [closed]

  - by Keith Groben

  Possible Duplicate: How to find web hosting that meets my requirements? I am frustrated to no end with my current hosting provider, mediaTemple. Yes, they are flashy, and have some decent degree of flexibility with their GS plan, which I have. But anytime I install a site that needs a database, it is slow. like really slow. Taking anywhere from 10 - 15 seconds just to load a page. I would host in house, but there are a lot of complications that come with a LAMP server that I don't want to deal with. Honestly, I'd rather spend the time developing. What can you recommend?

• How do I connect to a wireless network?

• Strategies for avoiding SQL in your Controllers... or how many methods should I have in my Models?

  - by Keith Palmer

  So a situation I run into reasonably often is one where my models start to either: Grow into monsters with tons and tons of methods OR Allow you to pass pieces of SQL to them, so that they are flexible enough to not require a million different methods For example, say we have a "widget" model. We start with some basic methods: get($id) insert($record) update($id, $record) delete($id) getList() // get a list of Widgets That's all fine and dandy, but then we need some reporting: listCreatedBetween($start_date, $end_date) listPurchasedBetween($start_date, $end_date) listOfPending() And then the reporting starts to get complex: listPendingCreatedBetween($start_date, $end_date) listForCustomer($customer_id) listPendingCreatedBetweenForCustomer($customer_id, $start_date, $end_date) You can see where this is growing... eventually we have so many specific query requirements that I either need to implement tons and tons of methods, or some sort of "query" object that I can pass to a single -query(query $query) method... ... or just bite the bullet, and start doing something like this: list = MyModel-query(" start_date X AND end_date < Y AND pending = 1 AND customer_id = Z ") There's a certain appeal to just having one method like that instead of 50 million other more specific methods... but it feels "wrong" sometimes to stuff a pile of what's basically SQL into the controller. Is there a "right" way to handle situations like this? Does it seem acceptable to be stuffing queries like that into a generic -query() method? Are there better strategies?

• Any examples of fair mmo games with quick completion

  - by Keith Player

  I'm looking for some example games for inspiration that allow from 10 to a large number of players at a time and can be completed in 10 to 30 minutes. I'm looking for something that would have extremely low bandwidth and not be dependent on chance or luck (i.e one player can't gain an unfair advantage because the computer put them in a better position). Realized on the way home that more clarifications might have been helpful. I'm looking to develop a pay-to-play competition that would allow a large number of players to compete in a relatively short period of time. One way would be to have an mmo that can be completed in 30 minutes, another way would be if you could have 10 person games that finish in under 5 minutes and then have the winners compete against each other until a winner is decided. I'm interested in any genre that would make for a fun/interesting game that doesn't depend on luck, so all players should have the same choice/availability of activities/resources and follow the same rules. Some possible games that could possibly be modified into what I want, would be bztanks (too easy to create a bot), diplomacy (takes too long), risk, some chess like game. I was just wondering if there are other game types to the ones I have been considering.

• Learning PHP MySQL [closed]

  - by Keith Groben

  I've been a designer for several year now. I'm now very interested in learning PHP, MySQL. I've read through W3Schools already and it helped me become familiar. I now want to know where I could go to start building some simple database and php applications so I could be come familiar with coding and start to improve. I think hands on application is the best way to learn. Since I'm a beginner, much of what I've found so far is sort of advanced to me.

• How to revert to 10.04

  - by Keith Mastin

  Since "upgrading" to 12.10, the multitude of problems and slowness has wondering me , if I'm running windows, so I want to take it back to 10.04. Just some of the problems that we never had in 10.4: Can't play YouTube and chat at same time; Can't open more than 5 photos in GIMP without constant grayouts; Can't easily close apps or programs on desktop; Can't Use Avidimux and Audacity at same time, CPU load stays at 100%; New Gnome is not nearly as intuitive as classic, focus is all over the place, have to constantly switch to have the focus on right window of same program (either browser), etc. Do I need to wipe my system partition and start over, or is there an easier way to downgrade?

• Ubuntu and surround sound

  - by keith

  I'm trying to connect my Logitech x.530 to my Dell studio 1558 and get 5.1 sound. I have 3 jacks and in Windows I automatically could switch between line in adn mic. Which means I could get 5.1 surround over these 3 jacks. Ubuntu does not realise that one of the three jacks should be switched to give sound to the center and LFE speaker. I tried all the tips in the forums, but nothing works. I can only select 4.0 sound in pulse audio. As the dell and the IDT 92hd89e chip for the sound are probably famous laptops I thought there must be someone who has similar issues in the 5.1 sound. I would like to stay at Linux but without this hardware support it's almost impossible.

• Multiple contacts with shared information

  - by Keith Thompson

  Background: I currently have several hundred contacts, synchronized between a Microsoft Exchange server and several mobile devices. I also save exported copies of the contacts in .vcf format. Is there a good way (application, file format, whatever) to maintain contacts with shared information? A very common scenario is that I have contacts for two or more people who live in the same house, for example: John Doe 123 Main Street, Anytown USA Home: 555-555-1111 Work: 555-555-2222 Mobile: 555-555-3333 E-mail: [email protected] Jane Doe 123 Main Street, Anytown USA Home: 555-555-1111 Work: 555-555-4444 Mobile: 555-555-5555 E-mail: [email protected] As you can see, both contacts have the same home address and phone number, but distinct names and work and mobile phone numbers. (Other information might also be either shared or distinct.) The applications and file formats I'm familiar with don't seem to have a good way to deal with this. If I use a single "John & Jane Doe" contact for both, it's difficult to distinguish the distinct information (if I want to call Jane's mobile phone rather than John's). If I use a separate contact for each, I have to remember to update both of them (or all of them for N 2) when they move or change their home phone number. An ideal solution would let me create a record containing information for their household, and have each of their contact records contain a reference to the household record, so that when I view John's contact record I see both shared and distinct information. Is there anything out there that has good support this kind of thing? (I would think there would be, since it's a very common scenario.) (I suppose I could roll my own system that generates merged .vcf files from some extended format, but that wouldn't play well with synchronizing across multiple devices.)

• php-cgi cpu usage is super high

  - by Ryan Thompson

  I am getting constantly high and wildly fluctuating CPU usage % for php-cgi commands as seen via "top" on my Centos server.. I have a server density account and it seems that this is a common trend: User - PID - CPU % - MEM % - VSZ - RSS - TT - Stat - Started - Time - Command 500 - 6389 - 22.4 - 3 - 271136 - 32380 - ? - S - 20:26 - 0:40 - /usr/bin/php-cgi Seems there are about 6 or so of those records in my processes list at any given check-in. Any ideas what's causing this? I have fast_cgi installed and the module is loading.. Not sure why it isn't handling this though. Any help would be greatly appreciated! Ryan

• Eclipse grinds to a halt when building workspace

  - by Chris Thompson

  Hi all, This is a bit of a vague question because, frankly, I don't even know where to begin diagnosing the issue. My eclipse (Galileo) installation grinds to a complete halt when it's building the workspace -- to the point where I can't even type. I know the Android SDK I have installed is a major culprit because I can watch the memory usage go through the roof (through the built-in heap monitor) when the Android SDK content loader starts up. Every time I save a file though, the program just stops. The message at the bottom of the screen says Building workspace (74%) and sits there for about 30 or so seconds before completing and returning the performance to normal. I have a few other plugins installed (Maven, SVN, etc) but I'm assuming the main issue is Android. Has anybody had similar issues or any luck correcting this sort of problem? If there's anymore information you think would be helpful, just let me know...I didn't want to do a core dump on this question... I'm running it on Windows 7 64-bit for what it's worth. Thanks! Chris

• Dual mode 802.11n PCI adapters

  - by Mike Thompson

  I have recently bought a DLink DIR-825 router. It is a dual mode (2.4GZ & 5GHZ) 802.11n wireless access point/router. What is a good PCI adapter to pair with it? DLink appear to only make one dual mode adapter, which is the DWA-160 USB adapter. They don't seem to have a PCI adapter in their range, which seems very strange. Do any of the other network manufacturers make a good dual mode adapter?

• Windows 7 login screen show only last user and "Other User" icons after profile problem.

  - by Mike Thompson

  I recently had a profile problem with my Windows 7 PC. My original profile in the registry had ".bak" appended to it and a new profile was created. I was unable to login with the new profile. I fixed this immediate problem by logging on in safe mode. This enabled me to restore my original profile. However, since that moment the login screen now operates differently. Instead of showing icons for all the users with accounts on the PC, it now only shows two icons. The first icon is the last user who logged on and the second icon always shows "Other User". I have tried several different solutions recommended by other people with similar problems, but none of them have fixed the problem. I think the person who started this thread has the same problem, but none of the proposed solutions helped him either. Any help much appreciated.

• Should I enabled 802.3x hardware flow control?

  - by Stu Thompson

  What is the conventional wisdom regarding 802.3x flow control? I'm setting up a network at a new colo and am wondering if I should be enabling it or not. My oh-cool-a-bright-and-shiny-new-toy self wants to enable it, but this seems like one of those decisions that could blow up in my face later on. My network: An HP ProCurve 2510G-24 switch A pair of Debian 5 HP DL380 G5's with built-in NC373i 2-port NIC LACP'd as one link. 9000 jumbo frames enabled. (Application) A pair of hand-built Ubuntu server with 4-port Intel Pro/1000 LACP'd as one link. 9000 jumbo frames enabled. (NAS) A few other servers with with single 1Gbps ports, but one with 100Mbps. Most of this kit is 802.3x. I've been enabling it as I go along, and am about to test the network. But as my 'go live' day nears, I am worried about the 802.3x decision as I've never explicitly used it before. Also, I've read some 10-year old articles out there on the Intertubes that warn against using flow control. Should I be enabling 802.3x hardware flow control?

• Client/server application RPC connection gets disconnected very frequently

  - by Chris Thompson

  I have a client/server application that uses RPC for the client to communicate with the server. Fairly regularly, I get an event in the Application log that the RPC connection was disconnected: Client callback failed ((0x80010108) ) I have the Windows Firewall disabled on both machines. I've even run the client on a second computer with a clean Windows XP install without any group policies. This has been going on for a long time and no one has been able to figure out why it's happening. The same client/server app works fine at other client locations. Any thoughts?
