• Sony Ericsson Windows driver problem

  - by alex

  I've installed Update Service and MediaGo for my Sony Ericsson phone but one of the drivers that was installed along with the software is causing problems in Windows 7 x64. Looking in the Event Log I see the following warning: Detected unrecognized USB driver (\Driver\seehcri) This is the driver corresponding to the Sony Ericsson seehcri Control Device. The failure to recognize the USB driver is causing problems with other services, namely the VMware USB Arbitration Service. It should normally start automatically but, due to the failure to recognize the seehcri USB driver, it fails with the following error: Error 31: A device attached to the system is not functioning. Disabling the driver has not helped at all. The VMWare service still refuses to start and I keep getting both warnings in the Event Log. I would like to remove the Sony Ericsson driver but unfortunately, that's not possible. Uninstalling the Sony Ericsson seehcri Control Device from Device Manager causes Windows to almost completely freeze up while trying to look for drivers for unrecognized hardware. Windows tries over and over again to locate and install drivers for an Unknown device, failing every time. Looking in Device Manager, it simply fills up with hundreds of unknown devices, also using up the CPU to almost 85% in the process. What should I do? How can I safely remove the driver without causing Windows to look for a new driver?

• Timeline chart in Excel

  - by Axarydax

  Hi, I'd like to see a timeline of events from a database in a "timeline chart", that should look like this: http://i46.tinypic.com/sw3dj5.png - I've made me a small c# program that paints this onto a Bitmap, but that isn't the way to go. I have input data that has 3 fields: StartX EndX Y 2596 15008 1 5438 6783 2 5450 5453 4 5456 5459 4 5462 5466 4 5470 5474 4 5477 5657 5 5662 5665 4 5668 5671 4 As the picture shows, for each line I'd like to have a line from StartX to EndX with a Y value of Y. Stacked bar chart almost solves my problem, but I don't want to have a new line on the chart for every row, I have thousands of rows and I'd like to have X axis as the time axis, and view which events (Y is the type of the event) happened simultaneously. The image ( http://i46.tinypic.com/sw3dj5.png) I've generated with a simple C# program shows that the event SYSTEM was active all the time, and the events TECH and BREAK were almost exclusive, but had some overlaps. I'd like to at least know the correct direction which I should take; I'm lost in the multitude of Excel chart types. Thanks.

• Crazy problem with Nginx, PHP5-FPM on Ubuntu

  - by Emmanuel

  I've been trying to get a domain from shared hosting to my new VPS. Everything was working just 100% fine, and then all of a sudden rewrites stopped working, pictures that should work started returning 404s. I've got no idea why, but for some reason on my site: http://www.onlythebible.com/ only the home page works, all the other pages depend on rewrites which were working perfectly fine at one stage, but all of a sudden stopped working. Some of the pictures like this url: http://www.onlythebible.com/bgsPreview/Matthew-8.10.jpg which doesn't use a rewrite throws a 404? I almost certain it was nothing to do with the nginx configuration. I've got suspicions that it could be something to do with php5-fpm? The funny thing is, all of a sudden it started working again. And then an hour or so later it broke again and has now gone back to only displaying the home-page and all of the links (and some of the pictures) are just showing 404s. Does anyone have an idea of what the problem might be? I'm pretty new to the whole Linux VPS thing, but this just seems very strange. *edit Here's a line from the error log which might shed some light on the problem: 2011/02/06 03:04:59 [error] 2873#0: *220 open() "/usr/local/nginx/html/bgsPreview/Matthew-8.10.jpg" failed (2: No such file or directory), client: 114.77.115.211, server: onlythebible.com, request: "GET /bgsPreview/Matthew-8.10.jpg HTTP/1.1", host: "www.onlythebible.com", referrer: "http://www.onlythebible.com/" I wonder why it's trying to find the file in /usr/local/nginx/html instead of the proper root which is /var/www/ etc... Oh, and for some reason it's just started working again... for how long I don't know. Another thing that was a bit weird, is that the pages on my website are pulled from a database. But when I edited the database, the pages didn't change... It's almost like they've been cached or something.

• Does any Certificate Authority support both SAN and wildcards?

  - by nicholas a. evans

  My basic quandry is that wildcard certificates don't support subdomains of subdomains, nor do they help with alternate domain names. Basically, if my CN is example.com, I want a Subject Alternative Name field that looks roughly like so: DNS:example.com DNS*.example.com DNS:*.beta.example.com DNS:example.net DNS:*.example.net DNS:*.beta.example.net Using a self-signed cert, I verified that the browsers will work just fine with this. Unfortunately, none of the Certificate Authorities that I looked into (Thawte, GoDaddy, Verisign, Digicert) seemed to support both wildcard certs and Subject Alternative Name (sometimes referred to as "Multiple Domain UCC"). I even called up GoDaddy tech support to confirm. Is there a CA (trusted by 99% of browsers) that supports wildcards for the Subject Alternative Name? One little restriction: I'm saddled with Amazon EC2's single Elastic IP per instance limitation. Here are what I see as my backup plans: set up three extra EC2 instances, each configured for a different IP address and cert, and nginx reverse proxy from three of them into the app server(s) introduces latency(?), and even the cheapest EC2 instance isn't that cheap instead of dedicated reverse proxy instances, setup the four or more almost identical EC2 app servers, with nginx using the port to determine which cert to deliver, and use haproxy to distribute the traffic amongst themselves. complicated to configure and manage? I'm not using the cheapest EC2 instance type for my app servers. If I don't need 4+ app servers for the load, it raises the cost. set up an external server (outside of EC2) that doesn't have EC2's Elastic IP address restrictions, setup all of the alternate IP addresses and certificates on that server, and nginx reverse proxy from that server into the EC2 app servers. extra IP addresses are almost free (still need to pay for the server of course), but don't come with the robust "elasticity" that Amazon's Elastic IPs provide. even more latency than in the first scenario. Are these approaches crazy or reasonable? Do you have another one to suggest?

• Broken Creative DTT3500 Digital

  - by djechelon

  Hello, many years ago I bought a Creative DTT3500 Digital surround speakers system. It's been a while since my home theatre started behaving strange. During the past 6 months, I have noticed that the amplifier needed some time before correctly playing digital audio. Until a couple of weeks ago, it needed up to 5 minutes of very noisy "warm up" before playing an "almost" clear audio. Today, I found that even using the analog input (completely disabling digital inputs) the noise persists. Powering off and on the speakers doesn't work. Now, it's reasonable that after almost 10 years, the amplifier got broken. My problem is that I can't simply replace the speakers with another kit from another brand, since 2 speakers in my room are placed in the back wall, with coaxial cables going under the floor but not completely inside a single tube. I mean, I have coaxial extension cables starting from the DTT3500 amplifier, going into the wall, then under the floor in a plastic cable tube, then exiting the tube (still under the floor), connecting to the male coaxial connector of the original cable supplied by Creative, and continuing up to the point close to my bed where the speakers are. I could replace the speakers **only as soon as the new speakers have the same coaxial to bi-polar cables that Creative ships with DTT3500 Another option might be "repairing the amplifier", but I don't know if it's feasible, what should I or a technician look for in the amplifier, and how much would it cost (is it worth to repair or buy a new kit considering the problem above? What do you suggest me to do, basing on the above observation? Thank you.

• I used disk copy to clone my drive, now my windows 7 profile won't load correctly

  - by RzK

  I used easeuse disk copy, after acronis, clonezilla, windows image restore failed me. Basically it copys all sectors, I set it to skip bad sectors(40). The source drive works, it just gave me a couple errors and stopped booting at one point. The drive is an identical copy, minus 40 bad errors. The drive is set to C and active partition, I rebuilt the boot order. I've ran sfc /scannow and ran chkdsk /r chkdsk found 20kb of bad sectors if I remember right. Now the issue I get is when I log into my profile which was saved right, I get a blank light blue wallpaper (non-license) explorer.exe is not running, and there are only 4 processes running in taskmanager, including taskmanager. I would try a repair install but CRTL-E would not open, nothing will open once I force start explorer.exe, almost like all services are down. What should I do? Fresh install is almost not a possibility I will try and fix this issue. sfc /scannow /offbootdir=c:\ /offwindir=c:\windows returns "Windows Resource Protection could not perform the requested operation"

• NTFS: Deny all permissions for all files, except where explicitly added

  - by Simon

  I'm running a sandboxed application as a local user. I now want to deny almost all file system permissions for this user to secure the system, except for a few working folders and some system DLLs (I'll call this set of files & directories X below). The sandbox user is not in any group. So it shouldn't have any permissions, right? Wrong, because all "Authenticated Users" are a member of the local "Users" group, and that group has access to almost everything. I thought about recursively adding deny ACL-entries to all files and directories and remove them manually from X. But this seems excessive. I also thought about removing "Authenticated Users" from the "Users" group. But I'm afraid of unintended side-effects. It's likely that other things rely on this. Is this correct? Are there better ways to do this? How would you limit the filesystem permissions of a (very) non-trustworthy account?

• nVidia performance with newer X and newer driver abysmal with Compiz

  - by Nakedible

  I recently upgraded Debian to Xorg 2.9.4 and installed nvidia-glx from experimental, version 260.19.21. This was somewhat of an uphill battle as the dependencies for the experimental nvidia-glx package are still somewhat broken. I got it to work without forcing the installation of any packages and without modifying the packages. However, after the upgrade compiz performance has been abysmal. I am using the desktop wall plugin and switching viewports is really slow - takes a few seconds for each switch. In addition to this, every effect that compiz does, such as zoom animations for icons when launching applications, takes seconds. The viewport switching speed changes relative to the amount of windows on that virtual screen - empty screens switch almost at normal speed, single browser windows work almost decently, but just 4 rxvt terminals slows the switches down to a crawl. My compiz configuration should be pretty basic. Xorg is likewise configured without anything special - the only "custom" configuration is forcing the driver name to be "nvidia". I've fiddled around with the nvidia-settings and compizconfig trying different VSync settings, but none of those helped. My graphics card is: NVIDIA GPU NVS 3100M (GT218) at PCI:1:0:0 (GPU-0). This is laptop GPU that is from the Geforce GTX 200 series. Graphics card performance should naturally be no problem.

• Windows 3 Animated Background/Desktop/Wallpaper

  - by Synetech

  In the summer of 1995, I visited some family in Los Angeles. My uncle had a computer with Windows 3 (or some version thereof since Windows 95 had not been released yet). In Windows 3, there was no desktop or wallpaper like in later versions; instead you could set it to a simple pattern (still possible in later versions before XP) like hounds-tooth or bricks (interestingly, there seems to be next to nothing available on the Internet about this anymore; no screenshots and almost no pages). I recall being amused when I found a program (on the still young “world-wide web”) that would actually let you set an animated background. It was smooth and fluid and was quite an amazing thing at the time. If I recall correctly, it had several built-in animations including one of a light-orange-pink background over which storks flew towards the top-left, possibly with some light stuff floating in the “background” (they were actually animated and flapped their wings, not simply translated coordinates). The storks were somewhat simplified, black-line drawings. Over the years, I’ve tried finding it again a few times but never could. Worse, it’s become harder and harder over time as new programs came out and polluted the search results. I’m hoping that someone remembers this software and knows some useful information like the author or where to download it. (No, it’s not ScreenPaper. That was created in 1997 to let you set a screensaver as the Windows 95/NT4 background. This was at least two years earlier for Windows 3 and I’m almost certain it had these animations built-in—I don’t recall any stork screensavers for Windows 3.)

• Excel file growing huge (>150 MB)

  - by Josh

  There is one particular Excel file that is used by a number of employees at my company. It is edited from both Excel 2003 and 2007, with the "Sharing" feature turned on to allow multiple writers at once. The file has a decent amount of data on several sheets with some basic formatting, and used to be about 6MB, which seems reasonable for its content. But after a few weeks of editing, the file grew to 10, then 20 MB, and eventually skyrocketed to more than 150 MB, even though it still has about the same amount of data as before. It now takes 5-10 minutes to open it, and that much time again to save it. The first time this happened, I copied the content of each sheet into a new, blank workbook, and saved the new workbook; this brought it back down to about 6MB. Now, it has blown up again. The workbook uses the "Data Validation" feature to limit the values in certain columns to the contents of a few named ranges. Copying all the data into a new workbook means re-setting up all the data validation, which is a pain and not something that we want to do every month. As a troubleshooting step, I tried saving the file in "XML Spreadsheet 2003" format, hoping to get some insight into what was being stored. Sure enough, the file was almost a gig, and almost all of the 10 million lines look like this: <NamedCell ss:Name="Z_21D5114F_E50C_46AC_AA4F_C3FF540C717F_.wvu.FilterData"/> <NamedCell ss:Name="Z_1EE2BA5E_3011_4F9A_8ACD_E58835250FC4_.wvu.FilterData"/> <NamedCell ss:Name="Z_1E3BDCEA_6A72_4ECC_BF4F_7B03CC66181E_.wvu.FilterData"/> I've seen a few VBScripts online to manage and enumerate named cells that are hidden in Excel's built-in interface, though I wonder how they'd handle my 10 million named cells. What I really need, though, is an understanding of why this keeps happening. What actions in excel could be causing this?

• Which database to use and system/db administration by layman [closed]

  - by blah

  So my friend and I got briliant ;) idea for a business. Since it is not predictable whether it will work out or not, we decided to keep cost as low as possible to start with, in particular not to hire anyone. If it will work out as expected it will generate enough profit to hire professionals in few months. But for the first few months we'll be doing everything by ourselfs. He's a business/finance major, and I'm a software developer, so obviously I have to take care of IT :) It will be a webapp, written in python/django. My questions regarding this project: 1) What database should I choose? I'm experienced with oracle, and have been working with SQL Server for a while, but both of them are too expensive(at least now). It's a developer experience, I've never done any dba stuff. I'm looking for something free(as in beer). Looks like MySql or PostgreSQL are most popular in this sector. I would appreciate any comments on which db to choose. I'm open to any suggestions(it doesn't have to be MySql or Postgre). Here's what I know about data: It will be almost dates and numbers, a little bit of text. Searched mainly by dates. Data will almost never be updated, mostly inserted and browsed. From 30k to 300k new records/month. 2) Servers. My idea is to rent two dedicated servers. During normal operation one would be a web server(debian/apache), other would be a db server(debian/?). My recovery plan is to install everything on both, and in case of trouble with one of machines just run everything on the other one. Does it even makes sense? Any other tips appreciated. Thanks.

• No digital audio output with Asus Xonar DG

  - by Lunatik

  I've purchased an Asus Xonar DG as replacement for faulty onboard audio in a Medion 8822 as it has an optical output which is all I really need to feed my HTPC. I uninstalled the previous drivers/devices, switched the PC off, inserted the Asus card, powered up, disabled the onboard audio in the BIOS, then installed the driver that came on the CD (same version as on Asus' website as of today) and everything went perfectly - no errors. I set the audio devices up in Windows and in the Asus utility (SPDIF enabled, 6-ch audio) as I would expect to see them work, but the only thing is I have no digital audio from test tones within Windows/the Asus utility, PCM audio or Dolby Digital from DVD. Analogue audio is fine. I've uninstalled things and reinstalled a couple of times now, as well as trying almost all combinations of analogue/digital outputs but can't get it sorted. Does anyone have any tips on how to get this working? This card has just been released so there isn't much out there to go on. Notes: The light on the toslink port is lit. OS is Vista 32-bit SP2 and all up to date, pretty much a fresh install with almost no 3rd party applications installed This page seems to suggest that a digital output device in Windows is not needed with Xonar cards as it was with the previous Realtek so I have it set to Analog. The only other output device is S/PDIF pass-thru

• Transparent proxying in MacOS X 10.6 Snow Leopard (and maybe FreeBSD)

  - by apenwarr

  I'm trying to create a transparent proxy on my MacOS machine in order to port the sshuttle ssh-based transproxy VPN from Linux. I think I almost have it working, but sadly, almost is not 100%. Short version is this. In one window, start something that listens on port 12300: $ while :; do nc -l 12300; done Now enable proxying: # sysctl -w net.inet.ip.forwarding=1 # sysctl -w net.inet.ip.fw.enable=1 # ipfw add 1000 fwd 127.0.0.1,12300 log tcp from any to any And now test it out: $ telnet localhost 9999 # any port number will do # this works; type stuff and you'll see it in the nc window $ telnet google.com 80 # any host/port will do # this *doesn't* work! After the latter experiment, I see lines like this in netstat: $ netstat -tn | grep ^tcp4 tcp4 0 0 66.249.91.104.80 192.168.1.130.61072 SYN_RCVD tcp4 0 0 192.168.1.130.61072 66.249.91.104.80 SYN_SENT The second socket belongs to my telnet program; the first is more suspicious. SYN_RCVD implies that my SYN packet was correctly captured by the firewall and taken in by the kernel, but apparently the SYNACK was never sent back to telnet, because it's still in SYN_SENT. On the other hand, if I kill the nc server, I get this: $ telnet google.com 80 Trying 66.249.81.104... telnet: connect to address 66.249.81.104: Connection refused telnet: Unable to connect to remote host ...which is as expected: my proxy server isn't running, so ipfw redirects my connection to port 12300, which has nobody listening on it, ie. connection refused. My uname says this: $ uname -a Darwin mean.local 10.2.0 Darwin Kernel Version 10.2.0: Tue Nov 3 10:37:10 PST 2009; root:xnu-1486.2.11~1/RELEASE_I386 i386 Does anybody see any different results? (I'm especially interested in Snow Leopard vs Leopard results, as there seem to be some internet rumours that transproxy is broken in Snow Leopard version) Any advice for how to fix?

• Why do I often have to refresh pages I navigate to once for them (or content in them) to load?

  - by GetOutOfBox

  I have noticed a bizarre pattern when using my PC, that when I open a link to a website, it often will often take a very long time to load, or time out. Sometimes content on the website will be drawn, but again, it seems to get "stuck" for an unusual amount of time before finishing. Most affected is Youtube; almost every time I navigate to a youtube video from another website such as Google, the video will not begin playing, but will instead just display the player controls with a black screen where the video should be and the buffering symbol, usually before displaying an error such as "The video failed to load". The unusual part of this problem is that whenever this happens, refreshing the page always causes it to load almost immediately the second time around, without any problems. Note that I'm not talking about how some browsers will dump whatever has been cached to the "pallet" briefly when the page is refreshed or loading stopped; but that the second time loading the website being faster. I have done my best to rule out some of the obvious causes: My Windows 7 desktop computer is the only device that seems to be affected. I use Firefox on it (latest version, flash updated, etc). My connection has more than enough bandwidth (30 megabits down, 4 up), and I've even tried QoSing all other devices to make sure this isn't happening due to usage spikes. Wireshark is not showing any clearly unusual network activity (i.e frequently dropped packets).

• Setup 2003 R2 Radius server to work on vista/seven

  - by Fox

  Hi All, I'm currently trying to configure my 2003 R2 server RADIUS module to enable WIFI client to authenticate throught my Active Directory. The RADIUS server use MS-CHAP V2 as encryption method. I got several Access Point running DD-WRT, configured to use WPA2-Enterprise security that use Radius Server. Everything is setup, and almost working. When I say almost working, I mean, I can login using my AD Credential on my IPod or even on a MacBook running OS X, Windows XP also work with some little tweak in connection properties. The problem is Windows Vista or Windows Seven clients computers that are not inside domain. It doesn't work at all, it doesn't even prompt for user/password/domain. I already install the patch for IAS to make the certsrv compatible with Vista and Seven, but still doesn't work. Anyone ever encounter the same issue I have right now? I'm searching for a solution to this for several already and still not find anything. Looks like many people have the same issue too. Thanks all for you eventual answers.

• sharing a folder between linux and windows over the internet

  - by valya

  Hello Currently my job is to make websites with Django. I use many things like virtualenv, PIL, etc. The problem is, I can't stand Linux on my desktop. I like it on servers, It's greate to use it over the SSH. But for desktop? No way. But for the development Linux is quite essential. Of course almost everything is ported to Windows, but it's not as simple to use as in Linux. For example, Windows shell is awful in comparison with Linux. So I've tried Cygwin, but it's too damn slow. Every time django dev server reloads, it tooks almost 20-30 seconds. In comparison, then using "native" python on Windows or Linux, it reloads instantly. Even worse, Cygwin makes all my system very slow. I've been thinking about it and have thought up a way to go. I can share a folder with my application with some Linux box. The devserver and everything will run on that box, while I'll be happy editing files and running the browser on my Windows 7. SSH shell is much quickier and handy than Cygwin. Currently there are no Linux boxes in my home network (except for my android phone :) but I have several VDS boxes with Debian. So, how do I share a Windows folder with VDS box? I can't rely on my desktop IP but I can rely on the VDS's one. I need sharing to be as quick as possible (well, 2-3 seconds ping is OK) and "native" for both systems, so I could use a folder like a normal folder in both Windows and Linux.

• Being a more attractive job candidate - Certs XOR Degree

  I'm currently working in an IT position, where I do helpdesk stuff, and predominantly security related issues/consulting (In the loosest sense of the term) In-House and for Service-Contract clients (as the only/acting CCSP [I guess I should say only person with Cisco experience] in my organization). I've professionally written Kernel Mode drivers for a gaming company. Among other things that I'm proud to put on a resume. I think of myself as very reasonably qualified as a System Administrator, With excellent Cisco experience, among other things I think would make a good addition to almost any IT staff in need of a new employee. However, Something has always tripped me up - Human Resources. Let me explain, I decided to skip the university route - I'm immensely glad that I did, The computer science graduates that I've met and work with rarely know much of anything about Computers (Until they gain some 'real' experience), Even when asked about Theoretical Computing fundamentals they can rattle something off about Turing Completeness but rarely do they understand the mathematical underpinnings. In short, I think instead of going to college, I'd rather pick up some real world experience. However, Apparently, Employers rarely think the same way. A quick perusal of jobs through the standard job search engine yields nothing short of a conspiracy to exclude anyone without 'A Bachelors Degree in Computer Science or Equivalent'. Interviews I've had in the past have almost always been entangled with - 1. My Age (Which I can't really change) and 2. Lack of Degree. Employers frequently disregard the CCNA/CCSP, The experience I've gained through internships, My extensive experience in x86 assembly and C, among so many other things I like to think are valuable to employers - In lieu of the fact that I don't have a piece of paper. So, AS AN EMPLOYER - Is it even worth working on my CCIE? Or should I pad my resume with certifications that are easier to acquire (Like CISSP, MSCE, Network+, etc.). Or should I ditch the whole idea and head back to get a Mathematics or CS degree?

• Transparent proxying leaves sockets with SYN_RCVD in MacOS X 10.6 Snow Leopard (and maybe FreeBSD)

  - by apenwarr

  I'm trying to create a transparent proxy on my MacOS machine in order to port the sshuttle ssh-based transproxy VPN from Linux. I think I almost have it working, but sadly, almost is not 100%. Short version is this. In one window, start something that listens on port 12300: $ while :; do nc -l 12300; done Now enable proxying: # sysctl -w net.inet.ip.forwarding=1 # sysctl -w net.inet.ip.fw.enable=1 # ipfw add 1000 fwd 127.0.0.1,12300 log tcp from any to any And now test it out: $ telnet localhost 9999 # any port number will do # this works; type stuff and you'll see it in the nc window $ telnet google.com 80 # any host/port will do # this *doesn't* work! After the latter experiment, I see lines like this in netstat: $ netstat -tn | grep ^tcp4 tcp4 0 0 66.249.91.104.80 192.168.1.130.61072 SYN_RCVD tcp4 0 0 192.168.1.130.61072 66.249.91.104.80 SYN_SENT The second socket belongs to my telnet program; the first is more suspicious. SYN_RCVD implies that my SYN packet was correctly captured by the firewall and taken in by the kernel, but apparently the SYNACK was never sent back to telnet, because it's still in SYN_SENT. On the other hand, if I kill the nc server, I get this: $ telnet google.com 80 Trying 66.249.81.104... telnet: connect to address 66.249.81.104: Connection refused telnet: Unable to connect to remote host ...which is as expected: my proxy server isn't running, so ipfw redirects my connection to port 12300, which has nobody listening on it, ie. connection refused. My uname says this: $ uname -a Darwin mean.local 10.2.0 Darwin Kernel Version 10.2.0: Tue Nov 3 10:37:10 PST 2009; root:xnu-1486.2.11~1/RELEASE_I386 i386 Does anybody see any different results? (I'm especially interested in Snow Leopard vs Leopard results, as there seem to be some internet rumours that transproxy is broken in Snow Leopard version) Any advice for how to fix?

• Maintaining "Portability" Between Linux and Windows 7

  - by lokheart

  I am using the following ways in my office's Windows 7 machine to maintain my "portabilibity" when disaster strikes and I need to switch computer while I have no luxury of time for reinstalling all my program to the new PC. a majority of programs I used are portable, mostly from portableapp.com, like notepad+, GIMP, even R, I extract them and store them in a folder in My document, in a structure similar to the default portableapp installation when they are installed to a thumbdrive only a few software that portable version is not available and I will install them as usual all of my working files are stored in a folder in My document I regularly backup them all using syncback, because this program can keep versioning of my backup, and the backup is stored in a portable drive. One day I need to switch my computer and the operation is relative simple for me: I just move the two folders mentioned above into the my document folder of the new PC, install those few "non-portable" program in it, and this is almost done, some minor hiccups can be solved by reinstalling the portableapp into the drive. Overall speaking it is a smooth process. I would like to maintain the same degree of "portability" in my home Linux desktop (Ubuntu or Mint, I'm still deciding), that is, if my Linux crash and I need to reinstall it again. All I need to do is the move the two folder back to the new Linux, and most of my work will be almost ready to be worked on again. But I don't know how to find a Linux-alternative of portableapps. Being a newer to Linux, can anyone tell me whether this is possible in Linux?

• Exclude list of specific files in wget

  - by nanker

  I am trying to download a lot of pages from a website on dial-up and it can be brutally slow. I have almost got the perfect wget command, but because I'm downloading pages from the same site wget wastes times downloading the same standard images for each page. If I know the name of the default page images, is there any way to have wget ignore and thus avoid downloading those for each and every page? Here is an example of one of the wget commands that my shell script generates into another shell script to download all of the pages: mkdir candy-canes-on-the-flannel-board-in-preschool cd candy-canes-on-the-flannel-board-in-preschool wget -p -nd -A jpg,html -k http://www.teachpreschool.org/2011/12/candy-canes-on-the-flannel-board-in-preschool/ wget -c --random-wait --timeout=30 --user-agent="Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.3) Gecko/2008092416 Firefox/3.0.3" http://www.teachpreschool.org/2011/12/candy-canes-on-the-flannel-board-in-preschool/ -O "candy-canes-on-the-flannel-board-in-preschool" rm Baby-and-Toddler.jpg Childrens-Books.jpg Creative-Art.jpg Felt-Fun.jpg Happy_Rainbow-e1338766526528.jpg index.html Language-and-Literacy.jpg Light-table-Button.jpg Math.jpg Outdoor-Play.jpg outer-jacket1-300x153.jpg preschoolspot-button-small.jpg robots.txt Science-and-Nature.jpg Signature-2.jpg Story-Telling.jpg Tags-on-Preschool.jpg Teaching-Two-and-Three-Year-olds.jpg cd ../ Now I realize the script is not likely as savvy as it could be but it is doing what I need at the moment except that you can see from the rm command that I would just like to prevent wget from downloading the files in the first place if possible. I almost forgot to mention, there are two wget commands and that is because the first one downloads the page as index.html and for some reason it does not open in my browser, however, when I open it and look at it in vim all of the page's content is there, so I am not sure why it does not open. But if I just issue the second wget command as it is then that page, same file really with an alternate name, opens up fine. Something that if I could fix would also help to streamline the process.

• Best video codec to store my own collection

  - by Jack

  Hello! I think this question has already been asked but with different flavours. My problem resised in the fact that my camera (Canon G9) creates video with almost raw codec (I think it's plain old MPEG) so a 10 minutes video is almost 900mb. I would like to convert them in a format that has a good trade-off between space and quality, but I would prefer having the quality as good as the original (of course this is not possible because of lossy compression) just saving as much space is possible with a minimal lose of quality. Which codec should I look for? H264? It seems to be the champion of the moment.. otherwise which other ones could I try? XviD? Which parameters should I use? I mean how many kbits/s is a fair good bitrate to keep high quality? And what about audio codec? video specs are 640x480 at 30fps or 1024x768 at 15fps.. thanks in advance!

• HP Photosmart C4780 printer/scanner breaks netgear WNDR3700v3 router on connection

  - by CodeJunkie

  A few months ago, we upgraded our Netgear router's firmware. Immediately, we started having trouble connecting to the internet. Each time this problem would happen, every device in the house would stop being able to make new connections to the internet. For example, you couldn't open new pages in the browser, but if Skype was running when the problem happened, you could keep talking to people. The only solution to this problem seemed to be resetting the router to factory defaults. Eventually, we solved this problem by just downgrading the router firmware. A while later, we got a new Netgear router. Almost right away, the new router started having exactly the same problems as the old one did on current firmware. The network connection would stay active and the computer would say it had an internet connection, but you couldn't do anything online except for using Skype. We eventually figured out that this happens every time our HP printer gets onto the network. Any time the printer gets onto the wireless network, the whole network stops connecting to the internet almost completely. The only thing that will fix it at that point is to reset the router to factory specs, and unplug the printer so it can't get back onto the network. The Netgear router has the latest version of the firmware, but the printer/scanner is very old. It looks to me like this problem is probably a result of a firmware conflict between the printer and the router, but I'm not sure how to fix that problem. Here's some additional information: Printer: HP Photosmart C4780 Router: WNDR3700v3 Router firmware: V1.0.0.22_1.0.17 (Stock, up to date firmware) Why would the printer getting on the network cause the router to not be able to access the internet correctly until it was reset? What can be done to allow the printer to be on the network without breaking the network for all other devices? Edit: One other thing that happens during this internet problem is that multiple computers in the house display an "IP conflict" message repeatedly, and extremely frequently (as often as every five to ten minutes, and every time a connection to the wireless is made).

• How to verify system using right GPU, after system reset [duplicate]

  - by Antoros

  This question already has an answer here: Is my mobile AMD card being used? 2 answers OS: Windows 8 CPU: Intel® Core™ i7 Processor 3635QM GPU 1 : Intel HD Graphics 4000 GPU 2 : AMD Radeon™ HD 8870M other info: System Spects Problem: im unsure that CCC is using AMD card instead of Intel's, i have encountered several issues since updating to 8.1 and i don't know what to do What happened: Installed 8.1 patch first day After 1 minute of use, BBSOD, windows never loaded again System restore wouldnt recognize 8.0 restore points i did a system reset to windows 8 since the laptop was only 3 weeks old System Broke, it did restore to factory BUT kept the registry almost intact, i had to install almost everything again, since the factory drivers where working with the updated one's registry and several problems CCC Broke too <- What i've already done Installing new drivers on top of old ones didnt work, so i used AMD uninstaller first Uninstalled and Re-installed Intel's HD Graphics Driver Tried to install mobile center, but AMD told me that it wasnt compatible (even if thats the only driver that they provide via their page as seen Here) Tried to use Auto-Detect, couldnt install driver because card was disabled because it didnt have the drivers... (see what they did here?) Had to use a workaround with Samsung Update, the driver didnt appear as download so had to use search and downloaded the driver manually. Now the graphic card appears on device manager and catalyst but as 8800 series (not exact model), and cant check the card with neither dxdiag/GPU-z/HWMonitor when right-clicking on CCC only Intel card appears launching a game and using as "high performance" would speed it up a little but i cant be sure How to verify its working properly? HWMonitor wont show AMD card even when set to high performance Latest GPU-Z wont work because a problem with Intel's, and legacy ones wont either what can I do now? I don't even know if I fixed my problem or not, and i also want to to use Adobe Premier with it, and its locked (the option to run it with the amd card not intels) Edit: now it seems to work, but cant change the setting for adobe Premiere and other programs that i Need to
