• Firefox stalls on rendering when chrome doesn't

  - by amccormack

  I have a webpage that loads quickly 100% of the time in chrome, but only 10% or so of the time in Firefox. Looking at the fiddler capture, Firefox only loads 2 of the 100ish files being pulled before it hangs. The error does not seem to be on the server or network side, however, because Chrome never encounters a problem. How do I find the root of this stall? While I suspect Firefox's javascript execution is what is causing the hang, are there any particular methods to narrow down the search for the bad code?

• Switch Gmail Icons Back to Text Labels

  - by Jason Fitzpatrick

  If Gmail’s icon-based buttons annoy you, it’s now possible to switch them back to the old text labels with a simple settings toggle. At MakeUseOf they highlight the new option in Gmail and how you can switch back to the old button layout: So how do you make that happen? All you have to do is click on the cog button, choose “Settings”, and go to the the General tab. Scroll down to find the “Button labels” setting, and change it from icons to text. I know what I’ll be doing shortly; text-based button labels here I come.

• Using a SMTP Service for email

  - by Josh S.

  This may be a horribly obvious question, but I'm learning and just need someone to confirm it for me. I putting together a private social network that needs to email their members (through the social network software, Elgg) regularly. I'm hosting it on a shared HostGator plan (because they won't receive much traffic) and they'll email 10-1000 emails a few times a week. HostGator restricts you to 500 per hour. I'm also worried about deliverability. I've been searching up and down about how to throttle the emails so it will all send reliably... but then I came across the idea of an outside SMTP relay service. Would using an SMTP service resolve this issue? If so, any opinions on quality SMTP services?

• Why is the console hanging randomly?

  - by Josh M.

  Ubuntu 10.10 Server x64 installed as Virtual Box VM. Fresh install plus postgresql and tomcat6 installed via aptitude. Rebooted the server and now when I run some command the console hangs. For instance, I run "sudo shutdown now" and then nothing happens but I am not returned to the prompt. I hit CTRL+C and nothing happens except ^C appears on the following line. I can type whatever and it will show up inline. I switch to tty2 and try to login and I only get as far as [username][enter] and that console hangs. One other thing - after "sudo reboot" the console appears to hang (just like above) when shutting down tomcat6. Any idea what's going on or what I should check? Thanks!

• Book: Pro SQL Server 2008 Service Broker: Klaus Aschenbrenner

  - by Greg Low

  I've met Klaus a number of times now and attended a few of his sessions at conferences. Klaus is doing a great job of evangelising Service Broker. I wish the SQL Server team would give it as much love. Service Broker is a wonderful technology, let down by poor resourcing. Microsoft did an excellent job of building the plumbing for this product in SQL Server 2005 but then provided no management tools and no prescriptive guidance. Everyone then seemed surprized that the takeup of it was slow. I even...(read more)

• Is LightDM is broken? Autologin works

  - by Ben

  I recently upgraded my Mythbuntu box to 11.10. LightDM worked for a while and then I configured autologin on my user account. After some time, I've removed some packages to lean down the system. Now when I log out (from either Unity or Gnome Shell) I lose the X session, LightDM doesn't start back up. If I disable autologin through /etc/lightdm/lightdm.conf I get no login screen & no X. As I said, autologin works and gives me a Ubuntu Classic desktop. This is the only reference in dmesg to lightdm; [ 17.351023] type=1400 audit(1329530135.420:19): apparmor="STATUS" operation="profile_load" name="/usr/lib/lightdm/lightdm-guest-session-wrapper" pid=1097 comm="apparmor_parser" Can anyone help?

• Trying to develop a game with android for cracking glasses in different dimensions

  - by user46514

  I am trying to develop a game in android where I will have to punch a hole to get through the glass but not shatter the glass completely. The glass will show up in different forms of polygons and when a hole is created by a projectile, the rest of the polygon will still remain intact.Only a polygonal opening will get created at the point of impact with the projectile. I am new at game design in android but I was thinking that I would create a random polygon shape to show in the path and then at the point where the projectile hits it, I could create a glass polygon to create a splinter effect. The rest of the part of the glass that is randomly created at the point of impact, I could further splinter it into polygons flying at different angle. since I also need to capture the bits of glasses flying off and falling down with gravity. Is my solution the best efficient one at performance of threads or is there a better solution for this glass breaking effect. Thanks Dhiren

• LWJGL glRotatef() without rotating axes?

  - by Brandon oubiub

  Okay so, I noticed when you rotate around an axis, say you do this: glRotatef(90.0f, 1.0f, 0.0f, 0.0f); That will rotate things 90 degrees around the x-axis. However, it also sort of rotates the y and z axes as well. So now the y-axis is pointing in and out of the screen, instead of up and down. So when I try to do stuff like this: glRotatef(90.0f, 1.0f, 0.0f, 0.0f); glRotatef(whatever, 0.0f, 1.0f, 0.0f); glRotatef(whatever2, 0.0f, 0.0f, 1.0f); The rotations around the y and z-axes end up not how I want them. I was wondering if there is any way I can sort of rotate just the axes back to their initial position after using glRotatef(), without rotating the object back. Or something like that, just so that when I rotate around the y-axis, it rotates around a vertical axis.

• Invisible boundary on Synergy client

  - by Jayson Rowe

  I have a Desktop system (named 'desktop') with 2 monitors attached (one 1680x1050 and another 1920x1080 resolution), running a synergy server. I also have a small ITX machine (named 'tiny') to my right that has a single monitor running at 1280x1024. The dual-monitor desktop is the synergy "server" and the single monitor system is the "client". Synergy works fine with one exception; if I move the mouse to the client, I can't move my mouse below the top two-thirds of the screen - it just stops. I can grab a mouse attached to the computer, and it moves all the way down, but as soon as I touch the mouse attached to the server, it jumps back to the top of the screen. Is there an issue with my config? section: screens desktop: tiny: end section: links desktop: right = tiny tiny: left = desktop end Thanks in advance for any suggestions. +----------------------------+-----------------------------+ | | | | | | | | +-----------------+ | | | | | desktop 1680x1050 | desktop 1920x1080 | | | | | | | | | tiny 1280x1024 | | | |+---------------+| | | |XXXXXXXXXXXXXXXXX| +----------------------------+-----------------------------+-----------------+

• How to make a ball fall faster on a ramp?

  - by Timothy Williams

  So, I'm making a ball game. Where you pick up the ball, drop it on a ramp, and it flies off in to blocks. The only problem right now is it falls at a normal speed, then lightly falls off, not nearly fast enough to get over the wall and hit the blocks. Is there any way to make the ball go faster down the ramp? Maybe even make it go faster depending on what height you dropped it from (e.g. if you hold it way above the ramp, and drop it, it will drop faster than if you dropped it right above the ramp.)

• Build one to throw away vs Second-system effect

  - by m3th0dman

  One one hand there is an advice that says "Build one to throw away". Only after finishing a software system and seeing the end product we realize what went wrong in the design phase and understand how we should have really done it. On the other hand there is the "second-system effect" which says that the second system of the same kind that is designed is usually worse than the first one; there are many features that did not fit in the first project and were pushed into the second version usually leading to overly complex and overly engineered. Isn't here some contradiction between these principles? What is the correct view over the problems and where is the border between these two? I believe that these "good practices" are were firstly promoted in the seminal book The Mythical Man-Month by Fred Brooks. I know that some of these issues are solved by Agile methodologies, but deep down, the problem is still the principles still stand; for example we would not make important design changes 3 sprints before going live.

• PHP developer wanting to learn python

  - by dclowd9901

  I'm pretty familiar at this point with PHP (Javascript, too), up to the point of OOP in PHP, and am looking to branch out my knowledge. I'm looking at Python next, but a lot of it is a bit alien to me as a PHP developer. I'm less concerned about learning the language itself. I'm positive there's plenty of good resources, documentation and libraries to help me get the code down. I'm less sure about the technical aspects of how to set up a dev environment, unit testing and other more mundane details that are very important, aid in rapid development, but aren't as widely covered. Are there any good resources out there for this?

• Screen problems

  - by Erick

  I struggled a lot in order to install Ubuntu because of a problem with the video drivers caused by when installing the driver and after turning it on it just appears a black screen, which worked for me was to use the terminal with sudo setpci -s 00:02.0 F4.B=0 and the screen starts, but after rebooting the changes won't remain and I have to run that command again. My question is: How can I make the changes permanent and not to be in need to execute that command always when I shut it down? Original Question in Spanish: Problemas con pantalla He batallado mucho al instalar ubuntu por el problema con el controlador de video ya que al instalarlo al encenderla aparece solo una pantalla negra lo que me funciono fue usar desde consola sudo setpci -s 00:02.0 F4.B=0 enciende la pantalla pero al reiniciarla los cambios no se quedan guardados y tengo que volver a ejecutar ese comando mi pregunta es ¿como hacerle para que los cambios queden igual y no tener que estar ejecutando eso siempre que la apago?

• AJAX Requests & Client-Side JavaScript

  - by Sarah24

  I am new to AJAX and trying to understand a question I've been given: A HTTP request is generated by a form which contains some drop-down list. When the form is submitted, a new web page is displayed with some relevant text information (which is dependent on the list item selected). Now, the same parameters are sent to the server via an AJAX request, and the same text information is returned. Q. What tasks would the client-side JavaScript have to do to ensure a valid request was constructed and sent? Any useful links or quick explanations greatly appreciated.

• Is a company order to switch to a certain IDE a red flag?

  - by Justin Alexander

  I recently joined a rapidly growing startup. In the past 3 months the development team has grown from 4 to 12. Until now they were very laissez-faire about what developers used to do their work. In fact one of the things I initially found attractive about the company is that most programmers used Linux, or whatever OS they felt best suited their efforts. Now orders, without discussion, have come down that everyone is to switch to Eclipse. A fine editor. I prefer SublimeText2, but it's just my personal taste. Is this a red flag? It seems capricious and unreasonably controlling to tell developers (non-MS) what IDE or tool-sets to use if they are already settled in and productive.

• How to round currency values [migrated]

  - by Kenny

  I already have several ways to solve this, but I am interested in whether there is a better solution to this problem. Please only respond with a pure numeric algorithm. String manipulation is not acceptable. I am looking for an elegant and efficient solution. Given a currency value (ie $251.03), split the value into two half and round to two decimal places. The key is that the first half should round up and the second should round down. So the outcome in this scenario should be $125.52 and $125.51.

• The Information Driven Value Chain - Part 1

  - by Paul Homchick

  One hundred years ago, there were places on Earth that no man had ever seen.  Today, a man standing in one of those places can instantaneously communicate with someone who may be strolling down the street on his way to lunch half way around the globe.  Our world is shrinking and becoming virtual. It is a world of incredible bounty and speed where we can get a product delivered to us anywhere on earth within a day or two. However, this world is also one of challenge where volatility, uncertainty, risk and chaos are our daily companions. To prosper amid the realities of this new world, the enterprise needs a business model. Globalization and instant communications demand greater operational flexibility than ever before. Extended supply chains have elevated the management of risk to a central concern, and regulatory demands from multiple governments place an increasing burden of compliance on companies. Finally, the speed of today's business requires continuous innovation to keep from falling behind the global competition.

• What is the best way to bypass China firewall to allow SSH deploy@**.com

  - by Lap

  I am trying to bypass the china firewall and allow SSH deploy@**.com at the command console. This is because I need to test the games I wrote on apps.facebook.com/**. I tried VPN (both pptp and openvpn), but they aren't that great as connection speed slows down significantly. Since I am deploying the game in another site, my browser needs to download the game, which is super slow. What are ways of bypassing the firewall other than getting a VPN? I was thinking maybe have a computer outside China and using teamviewer to access...

• Project development without experience

  - by Raven13

  I'm a web developer who is part of a three-man team that has been tasked with a rather large and complex development project. Other than some direction and impetus from management, we're pretty much on our own to develop the new website. None of us have any project management experience nor do my two coworkers seem like they would be interested in taking on that role, so I feel like it's up to me to implement some kind of structure to the development process in order to avoid issues down the road. My question is: what can I do as a developer without project managment experience to ensure that our project gets developed successfully and avoid the pitfalls of developing a project without a plan?

• Difference left/right super button

  - by Erik Keemink

  When I press my left super key the gnome shell appears and when I press the right super key it does not. Moreover pressing right super + T does open a terminal at once, but when using left super I have to press the t twice, when I press the t only once it is similar to just pressing the t without holding super left. This last point also occurs with other shortcuts that I defined (like super+L, super+E), but not with super+up/down/left/right. What I want is to press either super key to get the gnome shell and to use either super key in combination with T to open a terminal immediately (and similar with other shortcuts). I use Ubuntu 12.04 LTS and the gnome 3 shell.
