  The 3.0.1 software update bricked my iPhone and I had to do a hard reset, wipe and reload to recover it. Has anyone else had their first Gen iPhone bricked by the 3.0.1 software update? Does anyone have any insight about what causes this update to brick 1G iPhones?

• Windows 7 - SKU change?

  - by Chris W

  I've done an install of Windows 7 Ultimate on my laptop when I meant to install Pro - i.e. I've already used the Ultimate license on another box and want the laptop to run Pro for which I've got keys spare. Is there a way to change the SKU of the installed version to downgrade it so that I can use my Pro key. I've got a fair bit of stuff on it and would like to avoid re-installing the OS if I can.

• Trouble with setting up Mac SSH with TP-LINK router

  - by arxanas

  I have a Mac running OS X 10.7.2, and a TP-Link TL-WR740N (whose control panel looks like this). Remote Login is on in the Mac's System Preferences, and port 22 is set to forward on the router. I can access my Mac as a web server using the external IP on port 80, which I have set up through the same port-forwarding mechanism provided by the router, but when I try to ssh server@external-ip, it just times out after a long while. (The same thing happens when I try vnc.) I can, however, ssh and vnc successfully into that computer while I'm on the same network when using its internal IP. Since ssh appears to work and port forwarding appears to work, I can't figure out what's causing the problem. Does anyone have any idea what might cause this?

• how to add parameters to startup delayer

  - by user23950

  Startup delayer is an application that is used to delay the execution of applications at startup. And I want to take advantage of this function so that the regular applications that I am opening would be automated. How can I use the parameters function so that I could choose what operating system I want to boot when virtual box is included in the startup delayer. What website I would want to be automatically opened with google chrome. What specific project will be opened in visual studio. And others. And please enlighten me if this is not the exact function the parameters has to perform. Please do tell me of other application that can do the things mentioned above.

• Windows XP does not list WPA wireless networks

  - by Tomalak

  What can be the reason that Windows XP does not show WPA-encrypted wireless networks? The laptop I have problems with is an older model (Toshiba Satellite Pro 6100) with Windows XP SP3 on it, fresh install. The wireless network card in it is an Agere product that lists as "Toshiba Wireless LAN Mini PCI Card". The networks showed up perfectly before I first tried to connect to one (it was set to WPA2). The connection failed (the card supports WPA only), then something must have happend and Windows hides these networks now. A manually configured WPA setup via Windows' own wizard works, I'm using it right now. The network just won't show up in the list of available network on its own. I suspect that XP incorrectly set a flag somewhere that this network card does not support WPA. Is there such a flag, and if so, how can I change it back?

• How do I pipe a list of numbers straight from the shell into a command?

  - by learnvst

  How do I pipe a list of numbers straight from the shell into a command? For exampe something like this [1,2,3,4] | sort would give 1 2 3 4 EDIT: In response to the answers kindly posted so far . . . I ask this, because I want to quickly test and debug a console application that takes many numbers as it input without having to type lots of individual values followed by carriage returns. I'd like to just type in the 'one liner' and hit the up arrow now and then to replay the command. Ideally, I'd like to do this without using a text file containing the values (which would obviously be the most simple way to do this.)

• sequential SSH command execution not working in Ubuntu/Bash

  - by kumar

  My requirement is I will have a set of commands that needs to be executed in a text file. My Shell script has to read each command, execute and store the results in a separate file. Here is the snippet which does the above requirement. while read command do echo 'Command :' $command >> "$OUTPUT_FILE" redirect_pos=`expr index "$command" '>>'` if [ `expr index "$command" '>>'` != 0 ];then redirect_fn "$redirect_pos" "$command"; else $command state=$? if [ $state != 0 ];then echo "command failed." >> "$OUTPUT_FILE" else echo "executed successfully." >> "$OUTPUT_FILE" fi fi echo >> "$OUTPUT_FILE" done < "$INPUT_FILE" Sample Commands.txt will be like this ... tar -rvf /var/tmp/logs.tar -C /var/tmp/ Commands_log.txt gzip /var/tmp/logs.tar rm -f /var/tmp/list.txt This is working fine for commands which needs to be executed in local machine. But When I am trying to execute the following ssh commands only the 1st command getting executed. Here are the some of the ssh commands added in my text file. ssh uname@hostname1 tar -rvf /var/tmp/logs.tar -C /var/tmp/ Commands_log.txt ssh uname@hostname2 gzip /var/tmp/logs.tar ssh .. etc When I am executing this in cli it is working fine. Could anybody help me in this?

• radvd is not assigning prefix

• How to submit Windows 8 bugs on Microsoft Connect?

  - by ahmd1

  I was testing Windows 8 release preview and came across several bugs. One of my friends suggested letting Microsoft know through Microsft Connect. So I went to this web site: connect.microsoft.com I don't think that I'm a stupid person. I'm pretty good at figuring software and websites out, but this one beats me.... So I click on the "Products currently accepting bugs" link and get a long list of products. First off, most of those names is something that I've never heard before. Then I try searching the page for Windows 8 and ... find nothing :) Can someone explain in one or two sentences how to submit bugs to Microsoft?

• Lightweight Linux distro that includes developer tools? (or, the most BSD-like Linux)

  - by RevAaron

  I cut my teeth on Minix and Slackware 1.1, but I've been in the OS X Wilderness for the last few years. I'm trying to standardize on a Linux distribution for personal and work-related use on less powerful laptops and under virtualization. So far, NetBSD and OpenBSD are the best fit for my purposes- but after plenty of frustration I've come to the conclusion that I need to stick with Linux to get the hardware and software support that comes with it. What I like about NetBSD/OpenBSD that I'd like to keep: X, but no default KDE, GNOME or XFCE! A sensible /etc and dot file setup- startx calls xinit, xinit looks for ~/.xinitrc; nothing more complicated than that is needed. Command line tools and file-based configuration: I shouldn't need a GUI to connect to a WAP. Decent selection of binary packages; building from source is OK, but nothing source-only like Gentoo. pkg_add (BSD) and apt-get both have treated me well in the past. Modest RAM and HDD requirements: boot + X + awesome+ two xterms takes up 80 MB on OpenBSD and 240 MB on Debian 5 and Crunchbang In my experience, most "lightweight" and Live CDs focus on a nice desktop environment crammed into a CD or USB stick; once you add build-essentials you end up with something just about as bloated as Ubuntu or Debian full install. Crunchbang is a great example. Thanks in advance for all suggestions!

• Add bookmarks to Delicious and Google Bookmarks at the same time

  - by BrianH

  I have used delicious.com (or back then, del.icio.us) to store my bookmarks for a long time now, and I love it. I was looking through some of my Google services, and realized they have a bookmarking service that integrates with your Google searches (I thought they had a bookmarking service before, but it went away? Maybe not). I like delicious just fine - I'm not interested in leaving. But I also like how my Google bookmarks are highlighted (and I'm guessing, brought to the top) in my search results so I can easily tell if I've bookmarked a site (kind of like the "promote up" feature). I can't even count the number of times I search for a site only to find I've been there months or years ago. If sites I've bookmarked in the past are highlighted in my search results, it makes it easier to pick which search result to go to. My question is around bookmarking tools: Is there a bookmarklet or Firefox addon that will let me save a bookmark to multiple services at the same time, in this case, Google and Delicious? Or maybe a service to sync my delicious bookmarks to Google bookmarks on a regular basis? I have used the Delicious addon since the beginning - it would just be nice to add a bookmark to multiple services with 1 addon. For that matter, it would be nice to add Evernote into the mix - click 1 button to save the page to Evernote, and bookmark the page in Google and delicious. EDIT on 7/30/2009 - Summary: A proposed solution is to use the Delicious addon and the GMarks addon to keep the 2 services in sync. I was not able to get the 2 addons to keep everything in sync, so it was also suggest to use the Google Toolbar with the Delicious addon to keep everything in sync. I personally have reservations with letting Google know about every single site I visit, I believe this solution will work, so I am accepting it as the answer. I still wish there was a solution that would let you post a bookmark/page to multiple services at the same time (delicious, google, evernote, digg, diigo, etc.). Thanks!

• Kernel panic while loading Mac OS X on VMWare

  - by Vladimir Gritsenko

  I'm trying to run Mac OS X 10.6.3 on VMWare 7.1 from within Windows 7 64 bit. Trying to run the OS X doesn't work - shortly after booting VMWare announces the machine's death with this pop-up message: The CPU has been disabled by the guest operating system. You will need to power off or reset the virtual machine at this point. The console has a more interesting announcement: The real-time clock was not properly initialized on your system! With a dump of the detected CPU speed (~2.9 GHz), FSB (~94 MHz) and bus ratio (31). Somehow, the code that panics is documented in an accidental .diff file here. Apparently, it commits seppuku if the bus ratio is greater than 30. I underclocked my E6500 to a slower speed, but this apparently didn't make any difference. I can think of two possibilities right now: The CPU info being read is constant, and defines the maximum ability of the CPU. In which case it appears I'm screwed. VMWare presents its own CPU info to the machine, which I can perhaps somehow change. If so, how? If these sound completely off, that's because I'm a real newbie in these matters. Here's hoping you guys can show me the light :-)

• Migrating Windows XP BOOT.INI Settings to Windows 7 Boot-loader

  - by Synetech inc.

  Hi, Two months ago my motherboard died, so I bought a used computer that came with Windows 7. I have since installed my old hard-drive, which had Windows XP on it, in this system. What I am trying to do now is to figure out a way to migrate the settings from XP's BOOT.INI into 7's boot-loader. Below is the BOOT.INI I used in XP (I have reduced the strings and updated the disks to point to the new location of the old HD. Oh and I am not clear on the drive letters. In XP, I could boot the recovery console or MS-DOS from a file in C:\ that contains the boot-sector. I am not sure what drive letter it would be called now—I had to manually change all the drive letters of the old partitions in Windows 7 because it auto-assigned them all wrong/differently). [boot loader] timeout=10 default=multi(0)disk(0)rdisk(1)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="XP" /fastdetect multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="XP (Safe)" /safeboot:network /sos /bootlog /noguiboot C:\CMDCONS\BOOTSECT.DAT="Recovery Console" /cmdcons C:\BOOTSECT.DOS="MS-DOS 7.10" /win95 I have looked around, and have only been able to find some bcdedit commands to add XP to the boot-loader, but none that include information on setting safe-mode for it (or changing any of the XP load options for that matter). Not surprisingly I suppose, I have not found anything on adding the XP recovery console or DOS to the Windows 7 boot-loader. (Yes, I tried EasyBCD, but that did not help; it had no options for XP, and the best I managed was to get a choice of booting 7 or normal-mode XP—choosing XP didn't even give the old XP boot menu.) Can anyone please tell me how to export the entries in XP's boot.ini to 7's boot-loader so that on boot, I can choose to load the following: Windows 7 Windows 7 (Safe-mode) (Windows 7 (The Win7 counterpart of the Recovery Console)) Windows XP Windows XP (Safe-mode) Windows XP (Recovery Console) MS-DOS 7.10

• Windows XP won't boot after drive transplant

  - by Nathan

  Hi all, I moved my hard drive from my Lenovo laptop into my Asus Eee PC netbook. When I started the netbook, after POST all I got was a black screen with a cursor in the upper left corner. I thought that the migration should work OK because this was a 32-bit version of Windows XP, and the Atom processor in the Asus should support the x86 instruction set. However, I don't know much about Windows, so maybe this was a dumb thought. I did verify that the BIOS can find the drive. It required major surgery to replace the drive, so any solution requiring me to remove the transplant drive is not going to fly. Keeping in mind that the netbook has no optical drive and that I have no other Windows computers (all my other computers run Linux), is there any way I can fix this problem? Thanks! Nathan

• Can I use a mini PCI-E card in a standard motherboard with PCI/PCI Express slots?

  - by White Phoenix

  I'm helping someone build a computer and they absolutely insist on having an internal Bluetooth adapter. I've been searching around for a PCI-E/PCI based Bluetooth adapter but I've had no luck finding one - I've found some discontinued ones but they have giant antennas coming out the back - the person I'm building the computer for doesn't want that. I've been repeatedly insisting on him simply getting a USB Bluetooth dongle, but he doesn't want one taking up his external USB slots. This is the motherboard I'm using for his build: http://www.newegg.com/Product/Product.aspx?Item=N82E16813157303 My question is if it's possible to use one of those laptop PCI-E cards in a motherboard like this that has PCI-E and PCI slots, or if the form factor is completely different and won't fit?

• What is the simplest way to build your own .deb package?

  - by Calvin Fisher

  Having used Ubuntu for several years now, I've assembled a short list of scripts and packages that I always install on my computers. I would like to pack them up into a .deb to make it easier to get set up on a fresh OS installation. I'm imagining, for instance, one package that would install all of my custom BASH scripts that I've made for common tasks, and another one that would depend on other packages (like w64codecs) that I always install but forget that I need to until I go to do something and it's not there. It doesn't even have to be by-the-book; I'm not looking to deploy these publicly. I'm just looking to roll up all these tasks into one sudo dpkg --install. To quantify "simple" or "easy," I mean to say that I'm looking for the method with the fewest steps requiring the least technical knowledge and, most importantly, taking the least time.
