• Best options for freelance or part-time programming? [closed]

  - by Andrew

  I apologize in advance if this is an inappropriate question for this SE. A few years back I was all set to study computer science and get a job programming, but went a totally different route and went into healthcare. I currently work as a paramedic on a rotating 24/48 schedule, so I have two days off for every day I work, and a decent bit of downtime on the days that I do work. I've been looking at ways to earn some extra money with all that spare time, and was wondering if it'd be worth the effort to try and find a part-time/freelance gig. I know HTML/CSS, PHP, and I'm pretty familiar with Python and Ruby (and Rails). Anyways, was hoping that someone could point me in the right direction as what "skill set" would give me the best chance to be able to land a part-time/freelance gig. I realize this is a rather open-ended question but any direction is appreciated.

• Procedural Planets, Heightmaps and Textures

  - by henryprescott

  I am currently working on an OpenGL procedural planet generator. I hope to use it for a space RPG, that will not allow players to go down to the surface of a planet so I have ignored anything ROAM related. At the momement I am drawing a cube with VBOs and mapping onto a sphere. I am familiar with most fractal heightmap generating techniques and have already implemented my own version of midpoint displacement(not that useful in this case I know). My question is, what is the best way to procedurally generate the heightmap. I have looked at libnoise which allows me to make tilable heightmaps/textures, but as far as I can see I would need to generate a net like this. Leaving the tiling obvious. Could anyone advise me on the best route to take? Any input would be much appreciated. Thanks, Henry.

• Is there a simple shopping cart I can add to my existing website?

  - by Kalessin

  I created a website for my wife, who knits scarves. The site simply displays the 18 different colours she has created, with a Lightbox-like large photo available when clicked. She would now like to give visitors the option to purchase online and pay with PayPal and possibly Google Checkout. We do not need a full ecommerce solution; I've looked at several and they all seem to be overkill for our requirements. We don't even need categories. "All" I want is something that will add products to a cart, take the customer details and integrate the payment provider. So far, the best solution I have found seems to be this script on Codecanyon and I wanted to find out if anyone knows of any better products before I commit to this route. Thanks for your help!

• Ping one remote server from another remote server

  - by user666254

  It's simple to ping a server in C#, but suppose I have servers A, B and C. A connects to B. A asks B to ping C, to check that B can talk to C. A needs to read the outcome. Now, first of all is this possible without installing an application onto B? In other words, can I perform the entire check from just running a program on A? If so, can anyone suggest the route I would take to achieve this? I've looked at sockets but from the examples I've seen these require a client AND server application to function.

• Graphics corrupt after upgrade from 11.10 to 12.04

  - by RiaanZA

  I'm stuck at the moment with an ubuntu that boots into an unusable white screen after upgrading from 11.10 to 12.04. I've tried booting into safe X mode but it just throws me back to the safe menu every time. Restore previous graphics driver, use default graphics configuration and set up new graphics configuration all don't work either. I've tried various methods of resetting the graphics from the command line, but none are working due to unmet dependencies. These cannot be fixed by doing the normal "apt-get -f install" because its saying there is a dpkg error in var/lib/dpkg/status (blank line relating to skype-wrapper). I haven't been able to find any other way to fix the dependencies yet. Can someone please give me some advice on what to do, I really don't want to go the re install route.

• What are the different branches of Programming? [closed]

  - by clueless

  I just want a very general overview about what are the actual 'branches' of programming in the industry. What are different paths one can choose as a programmer and what are the common frameworks/languages/platforms in those paths. Currently I'm well versed with C/C++ and Python and I'm a beginner with Django. I want to know this because I can't decide what to proceed with after this, which route to take. Hope it's not a very general question. Thanks!

• Resize hard drive partition to make more space for /var

  - by user3357381

  I am running out of space in the /var partition. I have plenty of space in my /home partition. How do I shrink the /home partition to make more space for the /var partition? I have read some blogs that say to use the GParted Live CD. As a new user, I'm not quite sure if this is the ideal route. What is the best way to create more space for /var ?

• Upgrade MySQL to 5.5 on Lucid, upgrade server to Precise or switch to Percona?

  - by xref

  Looking into upgrading mysql on our development server to which is running 10.04 so is stuck at MySQL 5.1, as it appears there is no apt-get support for upgrading to 5.5 except by certain 3rd party PPAs. So I'm looking for which route to take and what other people have done: a) Follow a couple year old guide to manually install MySQL 5.5 and then invest ongoing time into manually downloading and installing security updates every month or two? b) Upgrade 10.04 to 12.04, and from other peoples experience I work with spend several days working out the kinks of that large upgrade, then I'll have access to mysql 5.5 and easy apt-get installation of future security updates? c) Switch from MySQL to Percona Server 5.5 and get all the benefits of that version of mysql, plus easy apt-get updates with their PPA? d) Something else?

  I have searched and read over the Internet and also on askubuntu. i am using Ubuntu 11.04 and my question or the thing that I want to achieve is efficient use of both the connections and thus increasing my browsing and downloading speed. I want my system to decide which packet should be routed over which interface. I want to know if this is possible. For example, Is it possible to route alternate packets over the two interfaces ? Please let me know any Internet resource or If I would have to insert any code into the network drivers etc. ?

• What are good/fast methods to pull data from a database using JavaScript?

  - by Yatrix

  I'm pretty new to web technologies and I am creating a filter control that will have cascading controls. We are doing a lot of this through JavaScript and are debating the best route to take to the database. HTTPHandlers, WebServices and Ajax are all being considered (or a combination of them). We want to be able to handle a million rows in theory, so it has to be scalable to at that. We are going through JavaScript as our page must not do post-backs, if your'e wondering. I'm asking from an architectural standpoint, but will take any useful information. Links, control suggestions - anything you have, I'll happily listen to.

• How do developers find the time to stay on top of latest technologies?

  - by u2sonderzug

  I was a freelance web developer until circa 2004 when I started going down the management route but have decided to try to get back into development again (specifically JavaScript and HTML5 web/mobile web apps) and I really get the impression to be truly good at these and similar fast moving technologies a constant amount of time is required to be set aside to invest in getting better at existing skills in addition to learning new skills. I understand right now since I am getting back into things there is a pretty steep learning curve, but seeing how good many guys are out there - the only way I see of getting up there is putting in a serious amount of time. For those working as fulltime developers, what I am trying to understand is this - on most days, how much time in the office is spent actually grinding out code compared to learning/research. I could easily spend 2-4 hours daily getting on top of the best ways to go about doing things. Do most good developers who are employed full time invest significant hours outside of work sharpening their skills? Or maybe I'm looking at all of this completely wrong?

• How to define default gateway with multiple DHCP interfaces?

  - by DrumEater

  How does ifconfig determine which network interface to use as the default when DHCP assigns a default route for each NIC? It seems like it's in a race-condition and I need to have a more reliable solution. Is there a setting in /etc/network/interfaces that could define the preferred gateway? I read about "metric" but that did not seem to function. 10.04 LTS Server with two NICs on a managed network. IP addresses are assigned via DHCP which I do not manage. eth0 is assigned a private NAT address; eth1 is assigned a public IP.

• Even distribution through a chain of resources

  - by ClosetGeek

  I'm working on an algorithm which routes tasks through a chain of distributed resources based on a hash (or random number). For example, say you have 10 gateways into a service which distribute tasks to 1000 handlers through 100 queues. 10,000 connected clients are expected to be connected to gateways at any given time (numbers are very general to keep it simple). Thats 10,000 clients 10 gateways (producers) 100 queues 1000 workers/handlers (consumers) The flow of each task is client-gateway-queue-worker Each client will have it's own hash/number which is used to route each task from the client to the same worker each time, with each task going through the same gateway and queue each time. Yet the algorithm handles distribution evenly, meaning each gateway, queue, and worker will have an even workload. My question is what exactly would this be called? Does such a thing already exist? This started off as a DHT, but I realized that DHTs can't do exactly what I need, so I started from scratch.

Il semblerait qu'un employé de Redmond ait réalisé une feuille de route qui indiquerait une date de sortie pour le prochain système d'exploitation de Microsoft.

Ce qui n'est séparé de nous que de...17 mois. Le noyau du nouvel OS devrait être totalement remodelé afin de s'adap...

• Cloud proxying service

  - by ChristopherJ

  I have an app that mashes up images from Bing image search, it's hosted on Heroku written in rails. The app is client side in javascript, so the mashup is done on an html5 canvas - this means though that if I fetch the images direct from the Bing server, the canvas gets dirty and I can't save it. As a quick work around, i have set up a route on my rails app that simply proxies the request to Bing and passes the result back through. Obviously this is a very poor performance solution and will eat up my dynos very quickly. Can anyone suggest a more suitable option? At the moment I'm thinking maybe Amazon EC2 with apache mod_rewrite rules would be better performing and more cost effective. Is there a cloud service (or an app I could deploy to a cloud service) that would be more appropriate for proxying requests for me so that my javascript can fetch the images without dirtying the canvas?
