• Is it costly to leave the Console and Script features enabled in Firebug?

  - by parisminton

  For some time now, I've run Firebug constantly enabled to do quick DOM inspections, leaving the Console and Script panels disabled. I'm just starting to use these two features so I don't have to keep using alerts for testing and debugging. I enable them while I use them and turn them back off when I'm done. I'd like to know if these particular features can slow things down such that they shouldn't be left on round-the-clock. Like do they slow down page loads, use inordinate chunks of memory or something? I don't see anything about it in the Firebug wiki.

What is the "right/faster" way to do this task in each scenario ?

• question about offer letter from tech company [migrated]

  - by paul smith

  I just received an offer letter from a tech company and I am a curious if it is normal practice to state this in the offer letter: "Your salary will be reviewed on a regular cycle as dictated by company policy"?Is this normal? To me it sounds a little shady, but I might just be thinking too much which is why I'd like to hear from others who've seen/received offer letters before from tech companies.

  - by Andry

  I am developing a web blog using ASP.NET, but I guess that the tech details like this, here, is not important. My aim is to insert in every post I create those nice buttons to the social networks account of my visitors so that they can quote or post the link to the blog entry in their space. How can I do this? I guess it also de3pend on the social network I want to use. Lets say, now, that I want to have links to Facebook, Tweet and Google circle accounts. Thankyou.

• How should I describe the process of learning someone else's code? (In an invoicing situation.)

  - by MattyG

  I have a contract to upgrade some in-house software for a large company. The company has requested multiple feature additions and a few bug fixes. This is my first freelance style job. First, I needed to become familiar with how the application worked - I learnt it as if I was a user. Next, I had to learn how the software worked. I started with broad concepts, and then narrowed down into necessary detail before working on each bug fix and feature. At least at the start of the project, it took me a lot longer to learn the existing code than it did to write the additional features. How can I describe the process of learning the existing code on the invoice? (This part of the company usually does things in-house, so doesn't have much experience dealing with software contractors like me, and I fear they may not understand the overhead of learning someone else's code). I don't want to just tack the learning time onto the actual feature upgrade, because in some cases this would make a 'simple task' look like it took me way too long. I want break the invoice into relevant steps, and communicate that I'm charging for the large overhead of learning someone else's code before being able to add my own to it. Is there a standard way of describing this sort of activity when billing for a job?

• How can I be prepared to join a company?

  - by Aerovistae

  There's more to it than that, but this title was the best way I could think of to sum it up. I'm a senior in a good computer science program, and I'm graduating early. About to start interviews and all whatnot. I'm not a super-experienced programmer, not one of those people who started in middle school. I'm decent at this, but I'm not among the best, not nearly. I have to do an awful lot of googling. So today I'm meeting some fellow for lunch at a campus cafe to discuss some front-end details when this tall, good-looking guy begs pardon, says he's new to campus, says he's wondering if we know where he can go to sign up for recruiting developers. Quickly evolves into long conversation: he's the CEO of a seems-to-be-doing-well start-up. Hiring passionate interns and full-times. Sounds great! I take one look at his site on my own computer later, immediately spot a major bug. No idea how to fix it, but I see it. I go over to the page code, and good god. It's the standard amount of code you would expect from a full-scale web application, a couple dozen pages of HTML and scripts. I don't even know where to start reading it. I've built sites from scratch, but obviously never on that scale, nor have I ever worked on one of that scale. I have no idea which bit might generate the bug. But that sets me thinking: How could someone like me possibly settle into an environment like that? A start-up is a very high-pressure working environment. I don't know if I can work at that pace under those constraints-- I would hate to let people down. And with only 10 employees, it's not like anyone has much time to help you get your bearings. Somewhere in there is a question. Can you see it? I'm asking for general advice here. Maybe even anecdotal advice. Is joining a start-up right out of college a scary process? Am I overestimating what it would take to figure out the mass of code behind this site? What's the likelihood a decent but only moderately-experienced coder could earn his pay at such a place? For instance, I know nothing of server-side/back-end programming. Never touched it. That scares me.

• Should a primary key be immutable?

  - by Vincent Malgrat

  A recent question on stackoverflow provoked a discussion about the immutability of primary keys. I had thought that it was a kind of rule that primary keys should be immutable. If there is a chance that some day a primary key would be updated, I thought you should use a surrogate key. However it is not in the SQL standard and some RDBMS' "cascade update" feature allows a primary key to change. So my question is: is it still a bad practice to have a primary key that may change ? What are the cons, if any, of having a mutable primary key ?

• How to examine the speed of your code results?

  - by Goma

  Hi. Whatever was your choice PHP, ASP.NET, Ruby On Rails or even JSP. You know that you can develop a website to give a specific result or to do some tasks in many ways. I mean you can change your code to make it shorter (or for any other reason) but to give the same result. In this case how do you test which code was faster to excute so you choose it to make your website faster? I mean do you have any tools or ideas in how to test the time of execution for your code and compare it with time of execution after you do some edit?

• Working as a software developer in a small town [closed]

  - by James

  I'm thinking of moving back to a small town in the near future. Coming from a large city (Dallas), I'm worried about being able to find work as a developer. I've worked remotely for companies as a contractor before, but would prefer a full time position for health insurance. Has anyone successfully made a good career for themselves while living outside of a major city (the nearest big city will be Minneapolis, about 3 hours away)? If so, how did you do it and what steps could I take between now and then to maximize my chances for success?

• Issue with dynamic Quicklist in Unity

  - by costales

  I would like to add a Quicklist to Gufw app, but it isn't working. The code is here (you can install reading the INSTALL file): http://bazaar.launchpad.net/~gufw-developers/gui-ufw/testing/files/3 I added lines 52-54 to the view (a simple example) from the official API web: http://bazaar.launchpad.net/~gufw-developers/gui-ufw/testing/view/head:/gufw/view/gufw.py https://wiki.ubuntu.com/Unity/LauncherAPI self.launcher = Unity.LauncherEntry.get_for_desktop_id ("gufw.desktop") self.launcher.set_property("progress", 0.42) self.launcher.set_property("progress_visible", True) But nothing happen. But if I run this file with Gufw running: http://bazaar.launchpad.net/~gufw-developers/gui-ufw/testing/view/head:/gufw/test_launcher.py $ python test_launcher.py The progress bar appears! :/ I don't know what am I missing? :P Any idea? Thanks in advance! The environment is Ubuntu 13.04.

• Quickly Application making it run on startup

  - by unknownone

  I have a PyGtk application that I made using Quickly, and I would like to have it run on startup when installed. How would I go about doing this? I'm not sure if sticking the .desktop file in ~/.config/autostart/ would make it work or not. If that will fix it, I don't know how to add it to that folder since Quickly packages the project for you and has it's own installation script. Is it possible to modify what it does on installation? If possible, I would also like to add the program in the System Settings Personal tab, but I do not know how to do that. Thanks

• Referencing external javascript vs. hosting my own copy

  - by Mr. Jefferson

  Say I have a web app that uses jQuery. Is it better practice to host the necessary javascript files on my own servers along with my website files, or to reference them on jQuery's CDN (example: http://code.jquery.com/jquery-1.7.1.min.js)? I can see pros for both sides: If it's on my servers, that's one less external dependency; if jQuery went down or changed their hosting structure or something like that, then my app breaks. But I feel like that won't happen often; there must be lots of small-time sites doing this, and the jQuery team will want to avoid breaking them. If it's on my servers, that's one less external reference that someone could call a security issue If it's referenced externally, then I don't have to worry about the bandwidth to serve the files (though I know it's not that much). If it's referenced externally and I'm deploying this web site to lots of servers that need to have their own copies of all the files, then it's one less file I have to remember to copy/update.

• How can I search a Drupal site with the new Unity lens?

  - by Ognjen

  I'm creating a simple Unity lense for my college site which is based on Drupal, but I don't know how to adapt this command for Drupal API. Please help, it's python. We now create our query url, using the Wikipedia opensearch API url = ("%s/w/api.php?action=opensearch&limit=25&format=json&search=%s" % (self.wiki, search)) I'm using template to write lense following Wikipedia example http://developer.ubuntu.com/2012/04/how-to-create-a-wikipedia-unity-lens-for-ubuntu/. I don't know python but Im familiar with C. This Drupal API calling is the only problem I have to successfully develop a lense. Please help!

• How can you predict the time it will take for two processes in two different machines in a cluster to communicate?

  - by Dokkat

  I am trying to develop a computing application which needs a lot of memory (500gb). Buying a single machine for that is overly expensive. I can, though, buy ~100 small instances on Digital Ocean or similar, divide the memory in blocks and use TCP to emulate shared memory between the instances. Now, my question is: how can I measure/predict the time it will take for two processes in two different machines like that to share information, in comparison to IPC and shared memory? Are there rules of thumb? I don't want exact values, but knowing more or less how much faster one is would be very helpful in visualising the feasibility of this approach.

• Why are 3D game scenarios so big? and.. are them shareable? [closed]

  - by Néstor Sánchez A.

  First, I apologize if this is not the forum for these type of questions. I was wondering... 1- Why 3D games (such as GTA IV) uses so much gigabytes of space? And my half-answar was... because of their huge 3D scenarios. But wait! are not these scenarios made with vector graphics and textures? then.. why are so big??? 2- If they are so big... would really these companies make a whole new scenario for every new game they develop? that would be very inefficient. Doesn't exist "shareable" scenarios that can be used in different games and expanded to no rebuild a whole one (like "New York" or "Liberty City")???. I mean.. the scenarios is almost the same in terms of vertices, just with improved textures.

• portfolio building, working for closed-source vs open-source?

  - by jondavidjohn

  I've currently graduated from my first run at higher education, landed my first full-time gig as a web application developer, and absolutely love it. My question is that in looking for jobs I ran across many jobs that require a certain level of experience and code examples. Much of the work I am doing is both protected by a login, and closed source. How does someone, that is just starting out and needs to be building a resume, go about preparing for the next job. (no matter how much i love my current job, i feel like it's only responsible to always be preparing)

• How can I refactor a code base while others rapidly commit to it?

  - by Incognito

  I'm on a private project that eventually will become open source. We have a few team members, talented enough with the technologies to build apps, but not dedicated developers who can write clean/beautiful and most importantly long-term maintainable code. I've set out to refactor the code base, but it's a bit unwieldy as someone in the team out in another country I'm not in regular contact with could be updating this totally separate thing. I know one solution is to communicate rapidly or adopt better PM practices, but we're just not that big yet. I just want to clean up the code and merge nicely into what he has updated. Would a branch be a suitable plan? A best-effort-merge? Something else?

• Why are most websites optimized for viewing in portrait mode?

  - by NVM

  I simply cannot figure this out. Almost all monitors have an aspect ratio where width is much bigger than the height and yet almost all websites are designed exactly for the other way round? I am not really a web developer and am just experimenting stuff at the moment but this madness baffles me!!! Edit: The point is not that I would like to limit the height of a website. The point is that I'd wat it to somehow fill all available space when I have my 1920x1080 in landscape mode. Edit 2: See this to understand what I am saying

• Truly useful UML diagrams

  - by eversor

  UML has a jungle of Diagrams. Profile Diagrams, Class Diagrams, Package Diagrams... However, (IMH-and-not-too-experienced-O) I quite see that doing each and every diagram is overkill. Therefore, which UML Diagrams are more suitable in a web context, more expecificly a blog (we want to build it from scratchs). I understand that just because I used UML Diagrams does not imply that our code would be great and brilliant... but, it certainly would be better than just unplanified code...

• Is it illegal to use content in such a way?

  - by MHZ

  I have a couple of questions about the legality of the content of some websites. I am currently working on two websites and I would like to make sure I am not breaking any laws, by using some content like I am... Do I need to get a license to use images from the Internet (such as google.images.com) in my site, assuming they aren't a company logo belonging to another company? If not, am I allowed to use it after I modify it with a image editing software? If content such as phone numbers, e-mail addresses, website addresses, and text from websites can be found for free online, and I gather this information for a search engine based site that I am working on and offering this information on a paid basis (similar to google, but more specialized), is something that is legal? Note: I am not 'copying' or redirecting business from anywhere, to my site. The exact opposite, the site I am working on actually helps advertise businesses and make it easier for customers to find them.

• Education and Career Resources from Microsoft and the Community

  - by KKline

  Sometimes I'm timely in getting the news out on useful resources. And, other times, I'm a bit slower on the draw. As I told my friends back at New Year's Day, "As an official member of the Procrastinators Club, welcome to 2008!" On the other hand, it's always good to remind folks of great resources that are still available and on the shelf. Why? Well, the Internet hits us with such a deluge of constantly new material, that we often forget about the old(ish) stuff that's still really useful. Darth...(read more)

• GWT (Google Web Toolkit) Designer not working on Ubuntu 12.10

  - by Marian Lux

  The GWT Desinger is not working on Ubuntu 12.10. It worked on Ubuntu 12.04. I installed the Eclipse Plugin as described on the GWT Homepate If I want to open the Design-View (for an xml-GWT-File), Eclipse crashes (prompt closing of the application). I found this two workarounds for which are for 12.04 (but on 12.04 i did not need this to get it working - it worked out of the box for me). I tried them on my 12.10 Ubuntu but they are not working. But I have to say that I can't find the "Use WebKit for rendering GWT UI (if available)"-Flag. What can I do to get the GWT Designer working? I tested it successfully again on a 12.04 Ubuntu VMware image. If I don't get a solution, I have to downgrade my Ubuntu to 12.04 again.

• Real Time Monitoring System using .net [closed]

  - by sameer

  I need to develop the application which display the dashboard where data from various SQL DB is fetched from different servers and displayed. Now this need to happen real time we can have refresh time say 5 min. Here is my thought, suggest if anything is wrong. 1) To Develop the Windows Service to accumulate the data from various SQL Server Instance. 2) Then Persist those details into SQL DB from which Dashboard will displayed on the web page. 3) Fetch of data from Windows service will be trigger every x minutes. 4) SQL Server Instance details will be stored in SQL DB which Windows Service will be referring. Thus this approach make sense. Thanks..
