• Windows XP seemingly out of resources but plenty of free RAM and swap available

  - by Artem Russakovskii

  This one has been bothering me for years and so far I couldn't find an adequate solution. The problem occurs on pretty much every XP install I've done. After opening a variety of programs or the system running existing programs for a while, Windows seemingly runs out of resources, without telling me. There's ALWAYS free RAM. For example, it just happened to me and I had over a gig of free RAM. There are no viruses, spyware, or other nonsense - it is a Windows resource problem, but the question is which resource is it running out of, how does one pinpoint it, and how does one prevent it? Sometimes, this happens after running specific programs - for example, today it happened when I started Photoshop CS4 and Flash CS4 at the same time. I also noticed that restarting The Bat (email client by Ritlabs) seems to get rid of this problem for a while but again, this happens on machines that don't even have The Bat installed. So what does exactly happen? The symptoms are: pressing alt-tab doesn't bring up the list anymore - it just jumps to the next window instantly, very similar to the way Alt-Esc works, however in this case, it's due to not having enough resources to bring up the alt-tab menu random programs would randomly crash, citing random errors, out of memory errors, system resources, inabilities to do system calls, etc. random programs would start missing random parts - for example, Firefox top menus might disappear, pull up partial selections, or not pull up anymore altogether. IE might lose a few of its toolbars. Some programs might fail to redraw or would just plain go gray where the UI used to be. Windows itself never complains about running out of RAM, virtual memory, or anything at all, yet it's running out of something. The only clue I was able to find and apply the fix today was this Desktop Heap Limitation. I haven't confirmed the fix working as not enough time passed. In the meantime, what are everyone's thoughts?

• Broken fonts in Konsole KDE 4.3.4

  - by depesz

  I have a strange situation - after some upgrades a couple of days ago fonts in KDE Konsole broke. To make it more specific - standard fonts look more or less OK, but when I use my national characters (like acelnsózz) they all look broken - like from another font, or badly scaled. The same problem doesn't exist in GNOME Terminal. I usually use the Terminus font, so I used this for demonstration, but it shows in other fonts as well - if that will be necessary I will provide list. Konsole shot: GNOME Terminal shot: As for my settings: =$ cat /etc/X11/xorg.conf Section "Device" Identifier "Builtin Default intel Device 0" Driver "intel" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Monitor Vendor" ModelName "Monitor Model" EndSection Section "Screen" Identifier "Builtin Default intel Screen 0" Device "Builtin Default intel Device 0" Monitor "Monitor0" EndSection Section "InputDevice" Identifier "touchpad" Driver "synaptics" Option "CorePointer" EndSection Section "ServerLayout" Identifier "Builtin Default Layout" Screen "Builtin Default intel Screen 0" InputDevice "touchpad" EndSection =$ xdpyinfo | grep -E resolution\|dimensions dimensions: 1680x1050 pixels (444x277 millimeters) resolution: 96x96 dots per inch I tried forcing DPI in system settings (to 120), or adding monitor size to xorg.conf - so far nothing helped. Any idea on what should I do to make it work sanely again?

• Problem posting multipart form data using Apache with mod_proxy to a mongrel instance

  - by Ryan E

  I am attempting to simulate my site's production environment as closely as I can on my local machine. This is a rails site that uses Apache w/ mod_proxy to forward requests to a mongrel cluster. On my Mac OSX Leopard machine, I have the default install of apache running and have configured a vhost to use mod_proxy to to forward requests to a local running mongrel instance on port 3000. <Proxy balancer://mongrel_cluster-development> BalancerMember http://127.0.0.1:3000 </Proxy> For the most part, this is working fine. I can browse my development site using the ServerName of the vhost I configured and can confirm that requests are being properly forwarded to the mongrel instance. However, there is a page on the site that has a multipart form that is used to upload an image to the server. When I post this form, there is a delay of about 5 minutes and the browser ultimately returns a Bad Request Your browser sent a request that this server could not understand. In the error log for my vhost: [Tue Sep 22 09:47:57 2009] [error] (70007)The timeout specified has expired: proxy: prefetch request body failed to 127.0.0.1:3000 (127.0.0.1) from ::1 () This same form works fine if I browse directly to the mongrel instance (http://127.0.0.1:3000). Anybody have any idea what the problem might be and how to fix it? If there is any important information that I neglected to include, post a comment, and I can add to this question. Note: Upon further investigation, this appears to be a problem specific to Safari. The form works fine in Firefox.

• How to set up Zabbix to monitor SQL Server Failover Active-Passive Cluster?

  - by Sebastian Zaklada

  It should be simple, so it is just most likely my approach being totally off and someone will hopefully prod me into the right direction. We have a Zabbix 2.0.3 server instance set up monitoring a bunch of different servers, but now we need to set it up to monitor and notify any alerts in regards to the SQL Server 2008 R2 Failover Active-Passive cluster. Essentially, this is a 2 servers cluster, when only one of its nodes can be "active" at a given time, serving all SQL Server related requests, while the other server just "sleeps" and from the point of anyone logged on on that server - has all of the SQL Server related services in stopped state. We have tried setting up Zabbix agents on both servers, using SQL Server 2005 templates (we could not find any 2008 specific ones and the 2005 ones always seemed to be working just fine for monitoring 2008 R2 instances) and configuring Zabbix server for both of the servers, but we end up having constant alerts for the server being currently the passive one in the cluster. We have been able to look up various methods of actually monitoring the failover, but we have not been able to find any guidance in regards to how to instruct Zabbix, that in this particular case, only one of the servers in the group is expected to be in the online state, while the other can be just discarded and should not raise any alerts. I hope I made myself clear. Thanks for any guidance. I am out of ideas.

• How can I split 200Mbps of streaming traffic into routers?

  - by Jared

  As the title says, I have 200Mbps of streaming video traffic coming into my command center. How do I split the load between routers? Setup is like this: fiber --- router --- switch --- workstations I'm sorry I haven't dealt with this much traffic before. so please be gentle if you're going to kick me out :) EDITED FOR DETAILS: Okay, this specific project is for our company's IP CCTV system. We have deployed over 100++ cameras all over a building/campus and we have estimated each camera to take about 2Mbps of bandwidth each. Now, they're all connected to a switch and that's entirely fine. But coming into our command center, they have to be on a router since it'll get more than 200++ cameras next year (and I don't want to have too many hosts on one subnet). My plan was to have the 1st hundred on a 172.16.9.x block and the 2nd hundred on a 172.16.10.x block (all /24). The servers I have are currently sized to match (about 5 dual 6-core xeons) and I'd have about 19 workstations all streaming video from the 5 servers. (servers pull video from the cameras). But 200Mbps of constant traffic? How the hell do I even break this up? I need to have 1 gateway, to manage the routes... I honestly think I'm way in over my head.

• Mac "Steam needs to be online to update" - 404 fetching *_osx.zip.*

  - by Chris Boyle

  Since yesterday evening, when I launch Steam on OSX, a self-update progress bar appears instead (at 0 of 30MB or so). This bar does not advance, an error dialog appears: Steam needs to be online to update Please confirm your network connection and try again. The app then exits. This happens whether wifi or ethernet or both are connected, and pings to the outside world succeed throughout. If I look at the logs in Console, they are very similar to this example (though that's not mine). Specifically: Success! http://store.steampowered.com/public/client/steam_client_osx?date=718277 [...] Failed! http://cdn.store.steampowered.com/public/client/breakpad_osx.zip.27f59114a86fcd50533e1d7b128f9300947f9969 Failed! http://cdn.store.steampowered.com/public/client/steam_osx.zip.11a99384214805f2dd3be5084ba6be61d662f8ac Failed! http://cdn.store.steampowered.com/public/client/miles_osx.zip.d9fb546541f59c1fdd03962a605236b1021abab8 Requesting the first URL successfully returns some data including the filenames of the latter three, and requesting any of those gives me a 404 (I've tried multiple clients on multiple continents). Searches on Google and Twitter show about 10-20 others having this problem in the past 24 hours, but hardly the angry mob I'd expect if the problem affected all Steam OSX users. Things that have already been tried with no effect: Switching between wifi and ethernet. Killing all Steam processes including ipcserver. Moving the ~/Library/Application Support/Steam/registry.vdf file away. Requesting those URLs with other clients and from other locations. Interesting: that first URL with the date parameter returns the same content even without that parameter (thus would lead to the same 404s) suggesting that the problem is not necessarily specific to coming from a particular currently-installed version of Steam.

• Converting DisplayPort and/or HDMI to DVI-D?

  - by Jeff Atwood

  Newer Radeon video cards come with four ports standard: DVI (x2) HDMI DisplayPort If I want to run three 24" monitors, all of which are DVI only, from this video card -- is it possible to convert either the HDMI or DisplayPort to DVI? If so, how? And which one is easier/cheaper to convert? I did a little research and it looks like there isn't a simple "dongle" method. I found this DisplayPort to DVI-D Dual Link Adapter but it's $120; almost cheaper to buy a new monitor that supports HDMI or DisplayPort inputs at that point! There's also a HDMI to DVI-D adapter at Monoprice but I'm not sure it will work, either. AnandTech seems to imply that you do need the DisplayPort-to-DVI: The only catch to this specific port layout is that the card still only has enough TMDS transmitters for two ports. So you can use 2x DVI or 1x DVI + HDMI, but not 2x DVI + HDMI. For 3 DVI-derived ports, you will need an active DisplayPort-to-DVI adapter.

• Sharepoint Workflow "Failed on Start" only when powershell import script is called from task scheduler

  - by Matt Keller

  I created a simple PowerShell script that takes an XML file in a local directory on our sharepoint server and imports it into a specific SharePoint form library. (Content management enabled library if that makes any difference) This script works flawlessly if i run it from the PowerShell command line manually. I call it like such: ".\script_name.ps1". It completes without error and the item is imported into the form library successfully. The workflow begins on the item and everything is happy dandy. However, i run into issues when i setup a scheduled task using Windows Server 2008 R2's task manager. The task runs the script without error and it does actually import the XML into the form library. I looks perfectly normal just as if i had run the script manually. However, after about 10 or 20 minutes the workflow status for that item changes from "In progress" to "Failed on Start (Retrying)". The scheduled task in question is a basic task and has only one action. (Start a program) The "program/script" box is set to "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" and the "Add arguments" box is set to the path of the actual ps1 script. (C:\scripts\sharepoint_import.ps1) I've tried running the task as various users. I've also tried with and without the "Run with highest privileges" check box. Nothing seems to work. For reference, here is the script i am using to import items into the form library.

• grepping a substring from a grep result

  - by allentown

  Given a log file, I will usually do something like this: grep 'marker-1234' filter_log What is the difference in using '' or "" or nothing in the pattern? The above grep command will yield many thousands of lines; what I desire. Within those lines, There is usually one chunk of data I am after. Sometimes, I use awk to print out the fields I am after. In this case, the log format changes, I can't rely on position exclusively, not to mention, the actual logged data can push position forward. To make this understandable, lets say the log line contained an IP address, and that was all I was after, so I can later pipe it to sort and unique and get some tally counts. An example may be: 2010-04-08 some logged data, indetermineate chars - [marker-1234] (123.123.123.123) from: [email protected] to [email protected] [stat-xyz9876] The first grep command will give me many thousands of lines like the above, from there, I want to pipe it to something, probably sed, which can pull out a pattern within, and print only the pattern. For this example, using an the IP address would suffice. I tried. Is sed not able to understand [0-9]{1,3}. as a pattern? I had to [0-9][0-9][0-9]. which yielded strange results until the entire pattern created. This is not specific to an IP address, the pattern will change, but I can use that as a learning template. Thank you all.

• Setting SVN permissions with Dav SVN Authz

  - by Ken

  There seems to be a path inheritance issue which is boggling me over access restrictions. For instance, if I grant rw access one group/user, and wish to restrict it some /../../secret to none, it promptly spits in my face. Here is an example of what I'm trying to achieve in dav_svn.authz [groups] grp_W = a, b, c, g grp_X = a, d, f, e grp_Y = a, e, [/] * = @grp_Y = rw [somerepo1:/projectPot] @grp_W = rw [somerepo2:/projectKettle] @grp_X = rw What is expected: grp_Y has rw access to all repositories, while grp_W and grp_X only have access to their respective repositories. What occurs: grp_Y has access to all repositories, while grp_W and grp_X have access to nothing If I flip the access ordering where I give everyone access and restrict it in each repository, it promply ignores the invalidation rule (stripping of rights) and gives everyone the access granted at the root level. Forgoing groups, it performs the same with user specific provisions; even fully defined such as: [/] a = rw b = c = d = e = f = g = rw [somerepo1:/projectPot] a = rw b = rw c = rw d = e = rw f = g = rw [somerepo2:/projectKettle] a = rw b c d = rw e = rw f = rw g Which yields the exact same result. According to the documentation I'm following all protocols so this is insane. Running on Apache2 with dav_svn

• Virtualbox - differencing disk based on different differencing disk

  - by Klinki

  I'm trying to create differencing image based on differencing image in VirtualBox 4.2.18. Official documentation says it should be possible: http://www.virtualbox.org/manual/ch05.html#diffimages Basically I want to achieve this drive hierarchy: + immutable image with Debian and all software installed +---- differencing image with specific configuration, autoreset=off, readonly +-------- differencing image with autoreset=on +---- another differencing image for different virtual machine +-------- differencing image with autoreset=on I successfully created differencing image based on differencing image, but I'm not able to connect it to virtual machine :( It always shows error: Failed to open the hard disk .... cannot register hard disk ... because hard disk with UUID ... already exists Here is screenshot of Virtual Media Manager and error dialog Virtual Media Manager Window screenshot Very strange is that the new differencing image (tempdrive.vdi) doesn't have Actual Size 0. I wasn't able to connect it, but still, it has 36KB of data on it... This is very similar to this older question: How to create a chained differencing disk of another differencing disk in Virtual Box? but suggested solution is not working anymore in VirtualBox 4.2.18, so I posted it as a new question. (Limit for posting links and screenshots is quite annoying..)

• What's the state of the art in image upscaling?

  - by monov

  I like to collect cool pics and use them as wallpapers or for other things. Often, artists publish only low-res versions, probably for fear of theft. Example: Gabriel Pulecio's BIRDS Now, if I want to use that as a wallpaper, I'd have to upscale it, and obviously that'd make it look blurry because of the bicubic interpolation. I realize there's no real way to get a high-res version from a low-res pic, because the information is not simply there. That said, I'm wondering if heuristics have been developed for upscaling with less apparent loss of quality. Those would probably be optimized for specific image types. For photorealistic pictures, for cartoons with large flat areas, for pixel art... One algorithm I'm aware of is Seam Carving. It works for some kinds of pics, especially ones with a plain, undetailed or uninteresting background, and a subject that strongly stands out. But it's far from being general-purpose. Applying it to the above pic produces this. It looks quite sharp, but the proportions are horribly distorted because the algorithm is not designed for this kind of pic. Another is Pixel art scaling algorithms. Those are completely unfit for anything other than actual pixel art that's pixelized to begin with. For example, I tried the scale2x windows binary on my pic, but its output was nearly indistinguishable from nearest-neighbour scaling because the algorithm didn't detect any isolated pixely fragments to work from. Something else I tried was: I enlarged the image in Photoshop with bicubic interpolation, then I applied unsharp mask. The result looks pretty bad. The red blotch is actually resized reasonably well, but the dove is far from it. What I'm looking for is some app that makes a best-effort attempt at upscaling any input image while minimizing blurriness. If you know of any, I'll be thankful. Note that the subjective prettiness and sharpness of the result is what matters... the result doesn't need to be completely faithful to the original small image.

• How much does a computer actually cost?

  - by Cawas

  Ok, so when you buy a new notebook, you spend about $1 or $2 thousand with the OS included. When you make your own desktop machine you can get as low as $100 for a good one today, with not a single piece of software included. It can't be much lower, but it can go lot higher. People, including myself, tend to believe that's the price of a computer, but then there comes the softwares. I just stumbled upon a nice piece of application I could use myself, but it's very specific, very tiny, and most people would never bother about this. And it costs "just $12". That is a lot for something I may use just once or twice! OS upgrades, hardware malfunction, and your custom set of software actually raise the computer price quite a lot, thus this question: how much we pay in the end for our personal computers? I'd like to see some statistics on that. Maybe divided into 3 categories or something, but some data with averages, minimum and "maximum" costs would be very nice. Maybe a "cost per year" would be nice. Just wondering.

• Mod disk_cache permanent caching images and disabling reacurring header updates

  - by user135532

  I am trying to get mod disk_cache to permantly cache images retrieved from an image server on the webserver using ProxyPass. While the image is being retrieved correctly from the server and is served from the cache on further requests, then I am still having the webserver call the image server and causing the cached header to be updated. Because of load concerns then I need to never call the image server on a specific url again after it has been cached once, or extend the refresh time for as long as possible. The webserver is IHS 7.0 The mod's are mod_disk_cache.so, mod_cache.so, mod_proxy.so Version 2.2.8.0 Following is from my httpd.conf: ProxyPass /webserver/media/images/ http://imageserver.com/ws/media/images/ # Caching pictures <IfModule mod_cache.c> <IfModule mod_disk_cache.c> CacheDefaultExpire 2628000 #CacheDisable CacheEnable disk /webserver/media/images/ CacheIgnoreCacheControl On CacheIgnoreHeaders Cookie Referer User-Agent X-Forwarded-For X-Forwarded-Host X-Forwarded-Server Accept-Language Accept Host CacheIgnoreNoLastMod On CacheIgnoreQueryString Off #CacheIgnoreURLSessionIdentifiers CacheLastModifiedFactor 10000000.1 #CacheLock on #CacheLockMaxAge 5 #CacheLockPath CacheMaxExpire 1576800 CacheStoreNoStore On CacheStorePrivate On CacheDirLength 2 CacheDirLevels 3 CacheMaxFileSize 1000000 CacheMinFileSize 1 CacheRoot c:/cacheroot2 </IfModule> </IfModule>

• Sniffing at work- How to detect

  - by coffeeaddict

  Because of the place I work has some real issues (people) especially in IT and the owner, I wonder if we are being sniffed. Is there any way to tell if on a Vista 64-bit machine: 1) In system logs some identification that would tell me that someone might log into my PC such as an Admin 2) Something in the logs that would give me a flag about maybe I'm being monitored some other way? 3) How can I be sure that my gmail, hotmail, and chat is not being sniffed. I know there are things like Simp, etc. I'm talking about specific hidden system signs either in registry or logs. Obviously I'm not going to raise any suspicion by me asking our network admin. I don't trust anyone at this company. is there a good way to basically monitor for this as an end user? Could someone log in and basically watch me work and if so, would there be any goodies left behind for me to find out if this has happened other than visual signs which would not be present...maybe some running processes?

• Very slow browsing shared folder XP client/host

  - by Ickster

  I have a pretty straightforward setup where I'm storing media files on an XP pro machine, and sharing the folder to be accessed by other XP pro machines around the house. (Typically, there's only one client accessing the share at a time, although there may be several with the share mounted.) It's been working just fine for years, but I've recently started having some problems. A couple of days ago, the host PC had power disconnected while it was running. It was restarted and everything seemed fine initially, but since then browsing the shared folder from client machines has been extremely slow and actually reading data is all but impossible. The problem exists in every access method I've tried: Windows Explorer, VLC dialogs, command line, etc. My first thought was that the disk was experiencing problems, but there are no problems viewing the files locally on the host machine. My second thought was that there was a network problem on the host machine, so I removed and reinstalled drivers for the NIC with no change. My third thought was that there might've been a problem elsewhere on the network, so I swapped out hardware to no avail. I'm regrouping and trying to come up with a methodical approach to figuring out what might be wrong. I would of course be thrilled if you can suggest specific problems (Microsoft KB articles, etc.) that I might check, but I'm not expecting a silver bullet. If you can help me outline an approach to identify the problem (including recommended tools, e.g., disk checkers, network analyzers, etc.) I'd greatly appreciate it.

• Missing boot files in Windows 8

  - by Alex F. Sherman

  I had a partition with Windows 8 Release Preview, Windows' System Reserved partition and the empty space of the beginning of disk. I moved two partitions to the beginning of disk using Ubuntu Live CD and GParted. After that, the Windows Loader didn't boot and throw an error about missing files. I fixed it using the commands: bootsect /nt60 sys /force /mbr bootrec /rebuildbcd bootrec /fixboot bootrec /fixmbr When I used "Automatic repair" option from "Advanced boot" menu, it throw an error like: Windows can't fix your boot problems. For more information see file C:\Windows\System32\LogFiles\Srt\SrtTrail.txt In this file I found a description of the system repair actions and at the end of file: Boot status indicates that the OS booted successfully. Now, when I use the Advanced boot menu from Windows 8 (PC settings - General - Advanced startup) I receive an error: Restart your PC to try again. It looks like something didn't load correctly. Restarting might fix the problem. If this happens more than once, you might also be able to find help by searching online for the specific error code. Erorr code: 0x8007090. 0x80070490 is the error code ERROR_NOT_FOUND. What are the missing boot files and how can I restore them? List of files in System Reserved Partition: B:\bootmgr B:\BOOTNXT B:\Boot\BCD B:\Boot\BCD.LOG B:\Boot\BCD.LOG1 B:\Boot\BCD.LOG2 B:\Boot\BOOTSTAT.DAT B:\Boot\Fonts B:\Boot\memtest.exe B:\Boot\qps-ploc B:\Boot\Resources B:\Boot\Resources\bootres.dll and many *.mui and *.ttf files.

• Is this a File Header / Magic Number?

  - by Hammer Bro.

  I've got 120,000 files (way more, actually; this is just an arbitrary subset) of an unknown type. Linux file does not identify them (not that they're necessarily Linux files), nor do any other methods I've tried. There are only two hints about them that I currently have. One is that I suspect some compression is employed -- I have metadata that claims the file sizes are always some amount larger than what I observe. The other is that in 100,000 of these files, the first 16 bytes are always: ff ee ee dd 00 00 00 00 01 00 00 00 00 00 00 00 That really looks like a file header/magic number to me, but I just can't place it. Does anyone know what kind of files this would indicate? Alternatively, can anyone convince me that these suspiciously common bytes certainly do not indicate a specific file type? UPDATE I don't know the exact reverse-engineering details, but most of the files in our case are zips after the first 29(? or so) bytes are ignored. So in practice the problem is solved (we know how to process the files) but in theory the question is still unanswered -- I don't know which application routinely prepends about 29 bytes to its zips. [I'm not sure if I should leave the question open or not at this point.]

• Home server hard drive: 186k start-stop cycles in 325 days?

  - by j-g-faustus

  I set up a home server about a year ago, using Ubuntu server (10.04 LTS at the moment), four disks in RAID 5 for storage (WD Green 1.5 TB) and a laptop drive for the OS. Today the output of smartctl, a command line utility for checking the SMART attributes of a hard drive, tells me that the primary OS drive has had no less than 186,000 start-stop cycles in 325 days and may be nearing the end of its lifespan. The smartctl output is in "normalized values", in this case a number between 200 and 000, where 200 is "brand new" and 000 means "worn out". My disk gets 001. So I wonder what happened: 186k start/stop cycles in 7820 hours is about one start/stop per 2.5 minutes around the clock. This seems somewhat excessive for a computer that sees actual use once or twice per day. (The RAID disks are normal, averaging to one start/stop per day, as expected.) Does anyone have similar experiences, or pointers to what might be the issue here? Specifically I'd like to know Why the massive start/stop count? Do I have some sort of configuration issue? Could there be a background service that is causing trouble? Could having a laptop disk as the OS drive be part of the problem? Can anyone confirm or deny this? Here is the /etc/hdparm.conf configuration /dev/sda { apm = 127 spindown_time = 120 } and the most relevant parts of smartctl --attributes /dev/sda: smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen === START OF READ SMART DATA SECTION === SMART Attributes Data Structure revision number: 16 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x002f 200 200 051 Pre-fail Always - 0 4 Start_Stop_Count 0x0032 001 001 000 Old_age Always - 185875 9 Power_On_Hours 0x0032 090 090 000 Old_age Always - 7820 12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 109 193 Load_Cycle_Count 0x0032 118 118 000 Old_age Always - 246833 194 Temperature_Celsius 0x0022 107 098 000 Old_age Always - 36 As I generally prefer my drives to last more than a year, any advice is appreciated.

• Windows Home Server installation fails because it can't find the DVD drive anymore

  - by BBlake

  I've got an old Dell Dimension 8300 desktop I decided to convert into a WHS box. I popped in a pair of 1 TB SATA drives, which were recognized fine by the BIOS and the currently installed OS (XP), so I decided to go ahead and install WHS. Near the end of the installation, WHS acts like it can no longer find the DVD drives (either of them, the box has a DVDROM and a DVDRW). The specific error is gives is the "Can't configure storage" error. I've found several forums where people say they get this error if they remove the boot DVD during the installation (at the time of the first reboot). However, I never removed the DVD. After the error, if fails into WHS, so it did mostly install and I can work with WHS. However, it refuses to recognize the network card, video card and while it shows the two DVD drives, any CD/DVD I insert in either drive the system says is corrupted and unreadable, even though none of them are. I've tried several reinstalls both removing and not removing the DVD, but the result is the same regardless. Any other tricks anyone found? If I can't figure this out, maybe I'll just install SBS2008 and fake it up to be similar to WHS with some addin tools. Shouldn't be too hard to create something since WHS is based on SBS2003 anyway.

• Bluehost Emails Getting Blocked

  - by colithium

  A site for my client has the run-of-the-mill "website with users" email pattern. Create an account, get an activation email. Get an email when a subscription is expiring, etc. The site is hosted on Bluehost and currently it uses php's mail() function. There isn't much configuration that is allowed (as far as I know). The trouble is, about a third of these emails disappear into the void. They aren't in spam or junk folders, there's no bounce message, they just cease to exist. I've read about Bluehost email troubles but I can't figure out what my options are for fixing it. These aren't marketing emails, ie they have user-specific information contained within them. I suppose if a solution offers a good templating system that would be fine. What are my options? Excerpt of headers when delivered to a Gmail address: Received-SPF: neutral (google.com: 00.000.000.000 is neither permitted nor denied by best guess record for domain of domain@box###.bluehost.com) client-ip=00.000.000.000; DomainKey-Status: good Authentication-Results: mx.google.com; spf=neutral (google.com: 00.000.000.000 is neither permitted nor denied by best guess record for domain of domain@box###.bluehost.com) smtp.mail=domain@box###.bluehost.com; domainkeys=pass [email protected]

• Broken fonts in konsole kde 4.3.4

  - by depesz

  I have strange situation - after some upgrade couple of days ago fonts in KDE konsole broke. To make it more specific - standard fonts look more or less ok, but when I use my national characters (like acelnsózz) they all look broken - like from another font, or badly scaled. The same problem doesn't exist in gnome-terminal. I usually use Terminus font, so I used this for demonstration, but it shows in other fonts as well - if that will be necessary I will provide list. Konsole shot: gnome-terminal shot: As for my settings: =$ cat /etc/X11/xorg.conf Section "Device" Identifier "Builtin Default intel Device 0" Driver "intel" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Monitor Vendor" ModelName "Monitor Model" EndSection Section "Screen" Identifier "Builtin Default intel Screen 0" Device "Builtin Default intel Device 0" Monitor "Monitor0" EndSection Section "InputDevice" Identifier "touchpad" Driver "synaptics" Option "CorePointer" EndSection Section "ServerLayout" Identifier "Builtin Default Layout" Screen "Builtin Default intel Screen 0" InputDevice "touchpad" EndSection =$ xdpyinfo | grep -E resolution\|dimensions dimensions: 1680x1050 pixels (444x277 millimeters) resolution: 96x96 dots per inch I tried forcing DPI in system settings (to 120), or adding monitor size to xorg.conf - so far nothing helped. Any idea on what should I do to make it work sanely again?

• App-V Problems After SCCM 2007 SP2 Upgrade

  - by GAThrawn

  We're running an SCCM (MS System Centre Config Manager, successor to SMS) 2007 environment and delivering a number of applications to clients virtualized using App-V 4.5.1. The App-V apps are delivered by SCCM in Download-and-Execute, not streaming mode. The SCCM environment was recently service packed to SCCM 2007 SP2 (amongst other things this gives Win7 support). We also pushed out the updated SCCM clients to our workstations. This seems to have broken file associations for virtual apps for a large number of our users. The users can still open their App-V apps by finding the specific app on their Start Menu and clicking it's icon, but double-clicking an associated file in Explorer, or opening an email attachment gives the "This action is only valid for installed applications" error. There is a Technet blog entry from the App-V team talking about this issue "Upgrade to ConfigMgr 2007 SP2 may break App-V File Type Associations" but running the script there comes back saying "The User Interface option has been updated" but hasn't seemed to fix the problems for any of our users. Unfortunately the Technet blogs don't seem to have comments switched on so you can't see how this has worked out for other people. Anyone else had this problem, have you found any other way to fix it?

• The bottlenecks of any computer, what to look for?

  - by WebDevHobo

  Whether it is a laptop or a desktop, any computer is made up of several pieces of hardware that communicate with each other. Sending data back and forth to ensure that the user gets the desired results. I have seen some theoretical stuff on computers & hardware, but I wonder how it all comes together. CPU RAM Graphics Card L1 CACHE L2 CACHE L3 CACHE FSB ... And all other things. Which is the biggest bottle neck? Why would a person not want/need a big value in one of those categories in certain situations? P.S.: when reading the specs of the i5 750 processor, I came across this description: In place of the FSB, one or more high speed, point-to-point buses called Quick Path Interconnect (QPI) are used, formerly known as Common Serial Interconnect Bus or CSI. QPI features higher bandwidth than the traditional FSB and is better suited to system scaling. What is this, and how does it compare to FSB? EDIT: I am not planning to buy a computer at all. The goal of this question is to understand the internal relation of various hardware pieces, their specific functions and how they work together. For instance, I have heard to a somewhat higher-than-usual amount of L2/L3 Cache can help speed up your computer. What's up with saying that? Also I forgot to mention Hard-disk RPM.

• Should I use Evernote or Org-mode for taking notes?

  - by tobeannounced

  I am looking for an app that will help me manage my notes, and after coming across Org-mode, I was wondering whether Org-mode's functionality is strong enough that it can remove the need for me to use another note taking app (because org is more of a task management app), such as Evernote. My wishes for a note taking app are: can be accessed offline in some form, eg through an iPhone app or desktop client Org-Mode and Evernote can both do this, however it seems like MobileOrg is more aimed at tasks, rather than notes? If this is the case, I probably would use Evernote in addition to MobileOrg. I can clip web content into easily for research Evernote has the browser extension, how is it with Org-Mode? I know I can use c-c c-l, but how suited is it really for taking notes on stuff I am browsing in Chrome/Firefox? has voice notes on the iPhone and computer too, if possible Org-Mode cannot do this on the iPhone, on the computer could I record audio externally and then link the files in? I can add notes too on my iPhone & computer while not connected to the internet both can do this. The types of notes I am likely to have include: howtos/things I have learnt, documentation on my setup/stuff, research on things I may do in the future, ideas, and task specific notes. I have thought about where I would want to access each of these notes and will post that here if you think it would help. So, is Org-mode strong enough in note-taking and the requirements I listed that I can avoid the need to use a separate tool for taking notes?
