• #altnetseattle &ndash; Collaboration, Why is it so hard!

  - by GeekAgilistMercenary

  The session convened and we began a discussion about why collaboration is so hard. To work together in software better us engineers have to overcome traditional software approaches (silos of work) and the human element of tending to go off in a corner to work through an issue. It was agreed upon that software engineers are jack asses of jack assery. Breaking down the stoic & silent types by presenting a continuous enthusiasm until the stoic and silent types break down and open up to the group.  Knowing it is ok to ask the dumb question or work through basic things once in a while. Non-work interactions are pivotal to work related collaboration. Collaboration is mostly autonomous of process (i.e. Agile or Waterfall) Latency time should be minimal in the feedback loop for software development. Collaboration is enhanced by Agile Ideals, and things like Scrum or Lean Process. Agile is not a process, Lean and Scrum are process.  Agile is an ideal. Lean, Agile, Scrum, Waterfall, Six Sigma, CMMI, oh dear. . . Great session.  Off to the next session and more brain crunching. . . weeeeeeee!

• Screen gets stuck in a dim setting after waking up

  - by Mason Wheeler

  I've got a laptop that I recently upgraded from Vista to Windows 7. It works a lot better now for a lot of things, but there's one problem I've had happen a few times that never happened under Vista. When I put the system to sleep, then occasionally when I wake it up again, for no apparent reason, the screen's dim. Sometimes it's as if half the backlighting was turned off, and sometimes it's as if all the backlighting was turned off, all except for the mouse pointer, which remains as bright white as ever. Trying to change the screen's brightness does nothing, but rebooting fixes this. Has anyone else seen this? Any ideas on what's causing it or how to make it stop happening?

• System starts without sound in Lubuntu

  - by cipricus

  When I log in the sound is muted. Why is that? This image is from the Xfce mixer, while the lxde volume does not show that the sound is off. So, I can see the sound muted only in Xfce Mixer. But I can also start the sound in another application, Pulse Audio Volume Control, if I change a setting in Output Devices from Analog Mono Output to LFE on Mono Separate Devices: The Analog Mono Output option here sets in fact the Xfce Mixer in the mute position from the first image. Could this be related to managing sessions (and therefore to these question)? This happens in LXDE session as well as in Lubuntu session. Starting sound and logging out and in between any of these two sessions would mute the volume as shown. Starting the volume in one of these and logging out and then logging in into the Gnome session, the sound would be off; but then, after starting sound, logging out of Gnome and then logging in into any session, the sound would not be muted. But after restart it would be so no matter the session.

• New apache on mac

  - by Keith

  I have installed php5 apache2 mysql5 and postgresql84 using MacPorts. I realize my mac already has apache but it didn't have apache2 nor postgesql hooked up to use with php. I want to not use the default apple apache and use the new macports install. How do I tell my computer to stop looking at the old apache? When I do apachectl in the terminal I believe it is using the old apache. I would like to hook it up to use the new one. How would I do that? The new stuff is installed at /opt/local/apache2 and the old stuff is installed at /private/etc/apache2 I went to system preferences...Sharing...and shut off Web Sharing but when I do apachectl's that turns it on and off in the preferences. I'm running in Snow Leopard.

• Need to combine a color, mask, and sprite layer in a shader

  - by Donutz

  My task: to display a sprite using different team colors. I have a sprte graphic, part of which has to be displayed as a team color. The color isn't 'flat', i.e. it shades from brighter to darker. I can't "pre-build" the graphics because there are just too many, so I have to generate them at runtime. I've decided to use a shader, and supply it with a texture consisting of the team color, a texture consisting of a mask (black=no color, white=full color, gray=progressively dimmed color), and the sprite grapic, with the areas where the team color shows being transparent. So here's my shader code: // Effect attempts to merge a color layer, a mask layer, and a sprite layer // to produce a complete sprite sampler UnitSampler : register(s0); // the unit sampler MaskSampler : register(s1); // the mask sampler ColorSampler : register(s2); // the color float4 main(float4 color : COLOR0, float2 texCoord : TEXCOORD0) : COLOR0 { float4 tex1 = tex2D(ColorSampler, texCoord); // get the color float4 tex2 = tex2D(MaskSampler, texCoord); // get the mask float4 tex3 = tex2D(UnitSampler,texCoord); // get the unit float4 tex4 = tex1 * tex2.r * tex3; // color * mask * unit return tex4; } My problem is the calculations involving tex1 through tex4. I don't really understand how the manipulations work, so I'm just thrashing around, producing lots of different incorrect effects. So given tex1 through tex3, what calcs do I do in order to take the color (tex1), mask it (tex2), and apply the result to the unit if it's not zero? And would I be better off to make the mask just on/off (white/black) and put the color shading in the unit graphic?

• Help with running crontab from root

  - by user242065

  Im using OSX and having trouble getting a cron job to run. I type the following: $ sudo -i $ crontab -e I then enter: * * * * * root ifconfig en0 down > /dev/null 0 19 * * * root ifconfig en0 down > /dev/null 0 7 * * * root ifconfig en0 up > /dev/null and no success, the first line is for testing. I want it to shut off my internet. The next two lines I plan to leave in, once I get this working. If I type this in to the terminal the internet goes off ifconfig en0 down Why is my cron job not shutting down the internet? FYI: This is a follow up question from http://stackoverflow.com/questions/3027362/how-can-i-write-a-cron-job-that-will-block-my-internet-from-7pm-to-7am-so-i-can most of the comments there are people making fun of me. And a few attempts to solve the problem with out cron jobs.

• Hyper-V Machine drifts time all over, even with NTP

  - by MichaelGG

  Resolved The problem was Hyper-V on that machine. I removed Hyper-V, installed VMware Server, ran the same VM. Time sync issues went away (< 100ms difference after a day). My setup is like this: HYV1 - HyperV machine (non domain) - sync irrelevant AD1 - VM AD server on HYV1, sync'd to time.nist.gov. HyperV time sync off. S1 - Physical machine, sync'd to domain. S2 - Physical machine running HyperV, sync'd to domain. V1 - Linux VM machine on S2, sync'd to AD1. No HyperV integration. AD1 and S1 have fine sync -- stripchart shows less than 100ms difference. S2 drifts like crazy. Here's a bit of the stripchart against AD1: 18:33:22 d:+00.0010138s o:+05.4101899s 18:33:24 d:+00.0010138s o:+05.4319765s 18:33:26 d:+00.0000000s o:+05.4788429s 18:33:28 d:+00.0000000s o:+05.6089942s 18:33:30 d:+00.0010138s o:+05.7240269s 18:33:32 d:+00.0000000s o:+06.0421911s 18:33:34 d:+00.0081104s o:+06.5613708s 18:33:37 d:+00.0000000s o:+06.9096594s 18:33:39 d:+00.0000000s o:+06.8867838s 18:33:41 d:+00.0010127s o:+06.8936401s In 20 seconds, it drifted over a second. If I manually reset it to within 1s, within a few minutes it'll be back drifting about 2 seconds. Overnight it went from ~2s to ~5s. The Linux VM inside S2 has perfect sync with AD1. Here's the config: C:\Users\mgg>w32tm /dumpreg /subkey:Parameters Value Name Value Type Value Data ------------------------------------------------------------ ServiceDll REG_EXPAND_SZ %systemroot%\system32\w32time.dll ServiceMain REG_SZ SvchostEntry_W32Time ServiceDllUnloadOnStop REG_DWORD 1 Type REG_SZ NT5DS NtpServer REG_SZ ad01.mydomain ad02.mydomain C:\Users\mgg>w32tm /dumpreg /subkey:Config Value Name Value Type Value Data ----------------------------------------------------------- FrequencyCorrectRate REG_DWORD 4 PollAdjustFactor REG_DWORD 5 LargePhaseOffset REG_DWORD 50000000 SpikeWatchPeriod REG_DWORD 900 LocalClockDispersion REG_DWORD 9 HoldPeriod REG_DWORD 5 PhaseCorrectRate REG_DWORD 1 UpdateInterval REG_DWORD 30000 EventLogFlags REG_DWORD 2 AnnounceFlags REG_DWORD 5 TimeJumpAuditOffset REG_DWORD 28800 MinPollInterval REG_DWORD 2 MaxPollInterval REG_DWORD 8 MaxNegPhaseCorrection REG_DWORD -1 MaxPosPhaseCorrection REG_DWORD -1 MaxAllowedPhaseOffset REG_DWORD 300 I looked at the event log, and apart from warnings about sync (after it gets way out of sync), there's no other warnings. How can I go about troubleshooting this? It's the only machine that is having this problem. All the other machines (physical and virtual) are doing fine. Edit: To clarify: The VM (AD1) has integration turned off and syncs to time.nist.gov. AD1 is fine. It's the physical machine S1 that can't sync to AD1 and drifts all over. All the other physical servers are able to sync to AD1 just fine. Update So, it appears to be an issue of running the VM. The clock slips slowly with the VM off. Turned on, it immediately starts losing seconds. I swt the VM to only use half the resources, and that seems to have slightly mitigated it, for now. Thanks!

• Can't boot into Ubuntu from CD, or from Acronis True Image recovery disk

  - by ChrisA

  I can boot my computer off a home-burned-from-ISO-image Windows 7 (x64 or x86) installation CD, without problems. It's a Quad 6600, 4GB RAM, 8800GT and most of the time runs Win7 with no problems. However, if I boot off a CD containing Ubuntu (10.04 or 9.something IIRC), or a recovery disk created with Acronis True Image Home 2010, it: boots starts to load the OS from the CD then hangs ... and I have to reset. I've tried all these CDs on another computer, and they boot up into Ubuntu or Acronis respectively with no problems at all. Any ideas what to look for? Sorry this is a little vague but I have no idea where to start, really ... if there's more information needed I'll edit the question. TIA!

• Netbook performs hard shutdown without warning on low battery power

  - by Steve Kroon

  My Asus EEE netbook performs a hard shutdown when it reaches low battery power, without giving any warning - i.e. the power just goes off, without any shutdown process. I can't find anything in the syslog, and no error messages are printed before it happens. I've had this problem on previous (K)Ubuntu versions, and hoped updating to Ubuntu Precise would help resolve the issue, but it hasn't. The option in the Power application for "when power is critically low" is currently blank - the only options are a (grayed-out) hibernate and "Power off". I have re-installed indicator-power to no effect. The time remaining reported by acpi is unstable, as is the time remaining reported by gnome-power-statistics. (For example, running acpi twice in succession, I got 2h16min, and then 3h21min remaining. These sorts of jumps in the remaining time are also in the gnome-power-statistics graphs.) It might be possible to write a script to give me advance warning (as per @RanRag's comment below), but I would prefer to isolate why I don't get a critical battery notification from the system before this happens, so that I can take action as appropriate (suspend/shutdown/plug in power) when I get a notification.

• Why can't I connect to a Cisco wireless access point?

  - by spinlock

  I'm running a Lucid Netbook Remix on my Dell Inspiron 600m and I was not able to connect to the wireless network at the Hacker Dojo in Mountain View yesterday. There were plenty of other people on the network - MS, Mac, and Linux boxes - but my laptop would never get an ip address. I can connect to my home network, which is open, and I've never had a problem connecting at the coffee shop, which uses WPA. The Hacker Dojo is running WPA and we checked the password a number of times but got no love. Any ideas would be greatly appreciated.

• Disable laptop's display on boot when used with external display

  - by Ryan

  I keep my laptop tucked away and solely use an external display with it via HDMI. In Windows 7 display settings, I have it set up to "Show desktop only on 2 [my external display]" This works fine in all cases except when I boot the laptop when the external display is already connected. In that case, the laptop's display stays on and sticks at the Windows 7 boot logo unless I manually shut the display off. (I should mention that while the laptop's display is stuck at the boot logo, the external monitor and computer are running just fine.) The laptop is an Asus N56VZ with Nvidia 650m graphics and the latest drivers. I've checked Nvidia's control panel as well as the BIOS and nothing looked very promising. Any ideas as to how I can get my laptop screen to shut itself off after booting into Windows?

  We have recently completed a server replacement for a customer. They had SBS2011 using Exchange 2010. They now have Server 2008 Std R2 and Google Apps email. We have migrated the DHCP, DNS, Filserver and all 5 FSMO roles to the new 2008 R2 server (today). During the grace period for SBS2011 we intend to decomission the old server completely. Previous experience would suggest uninstalling Exchange 2010 then demote SBS2011 then remove from the domain and switch off. Can I simply demote SBS2011 without removing Exchange? Can't really find any walkthroughs on this. My concern is that if we simply turn off SBS2011 the AD is left in a mess with legacy Exchange objects making any potential reintroduction of Exchange difficult in future, plus I want to do it the right way!

• Won't boot after installing Ubuntu 12.04 sucessfully

  - by Matt

  I installed 12.04 successfully and rebooted (I took out my installation CD), and selected the newly installed Linux partition to boot from rEFIt. Then it just comes up with this error message: Error loading operating system which could not be more vague. Take that back. I guess it could say just "error." I don't even get to the boot prompt which limits what I can do. I cannot boot into rescue mode. I tried boot-repair, but it took more than 24 hours to check the system configuration, so I gave up on that. I'm running a Mac Mini with its main OS being Mac OS X 10.5.8. I have an alternate OS Windows XP installed, which was virtually destroyed by this Linux installation. I sacrificed my working, speedy Windows partition for something that won't even boot up. What was I thinking. My Mac partition is slow as crap. I've tried installing 12.04 many times with two different disks. The first time, I had one partition for Linux, then I had 2 (swap+main), then 3 (swap, main and BIOS), then 4 which is what I have now (swap, main, BIOS, and boot/grub). The only way I could get through the install without GRUB giving up was if I created a separate partition for it. Which was pointless, because it did install successfully, but it still doesn't boot up at all. Could rEFIt be booting off of the BIOS or one of the other partitions? Because if that's the case, there is no alternative, because Mac itself without rEFIt refuses to recognize a Linux ext4 (or 2 or 3) format partition. Apple always has to make everything so difficult. If I'm not mistaken, rEFIt is the only application of its kind for Mac. I can boot off of the CD back to the install/try screen. This is extremely upsetting, can you guys help? Please?

• Can I disable email alarms in iCal?

  - by Brock Boland

  I have iCal syncing with a Google Calendar account, and for some reason, some meeting invites that I accept wind up with an email alarm set for 10 minutes before the meeting. This causes iCal to send me an email through Mail.app at the appointed time. This is a pain in the neck, because Mail.app launches if it's not open (and since I use a different client, it never is), and if I'm offline, Mail.app starts throwing up error messages. And besides, I don't want meeting alarms in my inbox. Is there any way to completely disable email alarms in iCal? The only option I see is "Turn off all alarms" - but I don't want to turn off the pop-up windows, just the emails. I remove those alarms any time I come across them, but sometimes they slip through.

• Bluetooth adapter turned from working fine to unrecognized

  - by easoncxz

  i had been using bluetooth fine, with devices working, but today when i turned on my computer again bluetooth strangely failed. there is a bluetooth icon on the top bar, showing "bluetooth on", but if i click on the "bluetooth settings" item, a system settings window shows up and shows me a bluetooth on-off switch which is disabled (i.e. fixed to off). more information about my case: i am a new linux used, coming from windows, and do not know supposedly-obvious commands. i am using a laptop. it initially doesn't have bluetooth. i bought a built-in type (instead of USB type) bluetooth module, and added it inside the laptop. hence, i do not have a specific FN+* key for bluetooth. in windows, i needed to install an additional driver that was intended for other machines in my laptop's seires which have built-in (i.e. factoryly built-in)j bluetooth modules. the Fn+* key seemed to only affect wifi under ubuntu. i have been successfully using magicmouse with my later-added built-in bluetooth module/adapter on both windows and ubuntu i have been trying to tweak the magicmouse scrolling speed with commands rmmod something, modprobe hid_magicmouse --scroll_speed=45 --scroll_acceleration=30 or something, then added a file `/etc/modprobe.d/magicmouse.conf". the mouse seemed to be working fine with these changes. now if i run commands like hcitool dev, the shell tells me that i do not have any "Devices" or "adapters". i seem to have bluez installed, because when i type "blue" then tab-autocomplete, a bunch of commands like bluez-test-device pops up. -- update -- some commands and their results: easoncxz@eason-Aspire-4741-ubuntu:/etc$ hcitool dev Devices: easoncxz@eason-Aspire-4741-ubuntu:/etc$ hcitool scan Device is not available: No such device easoncxz@eason-Aspire-4741-ubuntu:/etc$ rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no 1: acer-wireless: Wireless LAN Soft blocked: no Hard blocked: no 2: acer-bluetooth: Bluetooth Soft blocked: no Hard blocked: no easoncxz@eason-Aspire-4741-ubuntu:/etc$ rfkill list 0: phy0: Wireless LAN Soft blocked: yes Hard blocked: no 1: acer-wireless: Wireless LAN Soft blocked: yes Hard blocked: no 2: acer-bluetooth: Bluetooth Soft blocked: yes Hard blocked: no

• Ubuntu not shutting down ( going to black screen ) 12.04

  - by Orrin Fox

  I am currently using a USB persistent install of ubuntu. its a simple 4GB drive with a 2.8GB partition ( casper-rw storage partition ). I setup an administrator account and set it to login automatically. I also removed ubiquity to simply use this as a go anywhere install. Heres my issue. Im logged in as my account, and I click the top right gear and select "shut down". Text pops up showing its quitting processes.. etc. and then goes to the plymouth animation. But... The screen goes black, and then it goes to the login screen. Now when im at the login screen i go into terminal ( alt+F2 ) and dont you know, im logged in as Ubuntu. so then I try the following: ubuntu@ubuntu:~$ sudo shutdown now It goes to the plymouth screen again as if its shutting down, AND the screen goes black once again but the computer has not turned off, as in the usb is still flashing the light, the fans are still on, the only thing off is the screen. Is this a bug? If not maybe i did something wrong? Perhaps its that I made an account but... if there is a work around for this please let me know. Thanks again, Fox

• Why does my terrain turn white when I get close to it?

  - by Starkers

  When I zoom in on my terrain it goes white: The further in I zoom, the greater the whiteness becomes. Is this normal? Is this to speed up rendering or something? Can I turn it off? I'm also getting these error messages in the console over and over again: rc.right != m_GfxWindow-GetWidth() || rc.bottom != m_GfxWindow-GetHeight() and GUI Window tries to begin rendering while something else has not finished rendering! Either you have a recursive OnGUI rendering, or previous OnGUI did not clean up properly. Does this bear any correlation on the issue? Update I create virtual desktops to flit between using the program Deskpot. Turning this program off and restarting has stopped the above errors appearing in the console. However, I still get white terrain when I zoom in. Not a single error message. I've restarted my computer to no avail. I have an Asus NVidia GeForce GTX 760 2GB DDR5 Direct CU II OC Edition Graphics Card. Any known issues? Update I don't think it's fog...

• How to fix choppy video with VLC player?

  - by Brian Ojeda

  When playing most movies in VLC player, the video feed is choppy. Furthermore, the sound is near perfect. Another catch is, this video issue wasn't always an issue. I use to play movies with no problem with video or sound. I can not pin point what has changed between the it use to work fine and the time it started being choppy though. I have an ASUS G73JW-A1. This system should be more than enough to handle the demand of playing HD videos. Movies that are normally effected are HD videos. These video range from 4 to 9 gigs. In addition, the videos are in MKV, MP4 (or M4V), and AVCHD (or M2TS) formats. I get the same results when playing move directly off my hard drive or off an external. Finally, all the drivers have been recently checked and updated if needed.

• How to get multiple open-source projects to use a standard way of doing something.

  - by Marco

  Problem In the last couple weeks, I've used 3 different "repository" tools (listed in alphabetical order): gradle ivy maven I'm calling them "repository" tools because I've also used sbt -- which fortunately uses ivy to manage it's cache or local repository. Each of these tools will create it's own repository. The defaults are: ~/.m2/repository for maven ~/.gradle/cache ~/.ivy2/cache Why can't they all use the same cache? Goal I'd like to change the world so that all three build tools could use the same cache. I'm looking for advice about issues I'm likely to run into and smart ways to get around them. By "use the same cache", I do not mean "retrieve from another build tool's cache". I mean "retrieve from and store in another build tool's cache". While I could go ahead and submit issues to the three projects, I know from experience (as a developer on an open source project), that if you want something done, you're best off getting it done yourself. Also, it seems like I need to get all 3 communities on board to some degree. What is the recommended approach for getting this kind of thing done? How do I approach the different communities? Do I work on patches for the 3 different projects, or would it be better off to create my own "interface" project that deals with these issues and have the 3 tools interface with that? Is this a standards question that I need to address on that front? Lastly, if I'm missing something and this is possible (in an globally configurable fashion), then please let me know.

• My Macbook Pro doesn't give any reaction when pressing the power button

  - by Juri

  An hour ago I closed the display my Macbook Pro. it goes into sleep mode. After dinner I returned, opened the display and wanted to continue with my work, but I recognized it was switched off completely. I tried to press the power button and received nothing. I also noticed that the green light on the power supply plug which is plugged into my Macbook is off. Same thing with a power supply from the Mac of a friend of mine. What could I try? Some suggestions? What could be the problem here?? I already tried using the battery to start, no success, also taking the battery out completely, no success. Even if I press the small button for showing the current battery charge, none of the leds starts. It's like the Mac is completely dead.
