• What do the readonly attributes in diskpart really mean?

  - by marzipan

  I am wondering exactly what the meaning is of the "Read-only" disk and volume attributes that you can twiddle in diskpart on Windows 7. I am trying to set up an external USB drive as an installation medium for my own software, so I'd like to protect it against casual or inadvertent changes by users who it is given to, so they don't screw up the installation files they might need in the future. From what I can tell by experimentation with diskpart, the volume read-only attribute is actually stored on the physical disk somewhere, because I can set it and it shows up when I take the drive to another machine. This is great because my users can't (easily) change any of the files on the volume, or format it from Windows explorer. However, the disk read-only attribute seems to be just an aspect of how the current machine is accessing the drive. When I set it I can no longer delete the volume in the disk via Disk Management, but when I take the drive to another machine, the attribute is no longer set and in Disk Management I can delete the volume on the disk. I guess I'm not that worried about my users doing that, but I am annoyed that I don't understand what these attributes are really doing. Another thing that I don't understand is that the "volume" read-only attribute actually seems to be global to the disk - if I have two volumes on the disk, and I set the readonly flag on one of them, then it gets set on the other one too. ?!? I have the feeling I'm not searching for the right docs - all I'm finding is diskpart docs that give the syntax for twiddling these attributes, not what they really mean. Any pointers would be very welcome! Thanks, Asa

• finding the best network latency between two countries

  - by Yoav Aner

  I know there are many tools to test for bandwidth and latency, but they all rely on having at least one host from which you can run those tests. I wonder whether there's an online source or some other way to guestimate the latency or speed between two countries (in general). For example, would a customer in Japan get lower latency if the server is located in Singapore or Australia? Is a user in India likely to get higher download speed from a server in the UK or in the US? Are there any online resources or some clever ways to answer those questions with a reasonable degree of accuracy? [UPDATE]: Thanks for the great suggestions from Raffael Luthiger. I didn't know about those looking glass servers. The submarine cable maps were also really cool to discover (Thanks to Jesper Mortensen). Also seems really wise if I could ask those network professional in the area for their experience, but obviously I don't have access to those. At least some of them are on SF :) However, I'm still a little unsure how to combine those resources to give me some measurements. This is the information I have: Two countries (A,B). I do have IP addresses of customers in country A (I can obtain those from the web server log files for example). Presumably I can find some looking glass servers in country B and run a trace to those IPs. What's the best measurements to use? Are there any scripts that help automate at least some of this process?

• How can I tell my dd-wrt router to use someone's Amazon Affiliates link when I point my browser to amazon.com?

  - by Michael Paul

  Here's what I'd like to do. Instead of a one-time donation to one of my favorite free tools (junecloud.com) I'd like to do what they suggest here and use their Amazon Affiliates link to do all my Amazon shopping. I shop at amazon once or twice a week, so this is a great way to let them earn lots of long-term cash without me dropping a dime. My thought was to go into my dd-wrt enabled router and tell it, "any time I go to amazon.com on any computer in the house, please go to http://www.amazon.com/gp/redirect.html?link_code=ur2&tag=junecloud-20&camp=1789&creative=9325&location=%2F instead. (That URL simply redirects me to amazon.com but every purchase I make during that session is credited to JuneCloud.) Once logged into dd-wrt, I went to Services Services DNSMasq but I'm not really sure how to get it to work from there, or if it's even possible. I know I can redirect IP addresses, but I'm looking to redirect someone on my network from amazon.com to the special amazon affiliate code link. Hope that's clear. Thanks for any replies!

• keepalived issues on xen domU

  - by David Cournapeau

  Hi, I cannot manage to run keepalived correctly on xen domU. I am following this link for configuration, and it works great on some local VM (running with KVM). If I set up the exact same configuration, but on xen domU, it does not work: both servers do not see each other and decide to be master (10.120.100.99 being the virtual IP) $ sudo ip addr sh eth0 # host1 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:16:3e:78:f5:31 brd ff:ff:ff:ff:ff:ff inet 10.120.100.104/24 brd 10.120.100.255 scope global eth0 inet 10.120.100.99/32 scope global eth0 inet6 fe80::216:3eff:fe78:f531/64 scope link valid_lft forever preferred_lft forever $ sudo ip addr sh eth0 # host2 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:16:3e:51:36:20 brd ff:ff:ff:ff:ff:ff inet 10.120.100.105/24 brd 10.120.100.255 scope global eth0 inet 10.120.100.99/32 scope global eth0 inet6 fe80::216:3eff:fe51:3620/64 scope link valid_lft forever preferred_lft forever Is there a way I could debug this - it seems some people are able to use keepalived on xen following some mailing list, but without much info on their config.

• Tool for search, watch and download youtube videos on Ubuntu

  - by Mike

  I am looking for a tool like MacTubes for Ubuntu. MacTubes is a mac app that can search, watch and download youtube videos. The great advantage of this app is that it searches youtube and shows all videos available there and allows you to select all and download everything fast and easy. MacTubes is so awesome that it also converts the video to MP4 and downloads the HD version of a video when available. I use this on my mac, but my sister uses Linux and I am looking for something like that for her. I have tried Miro, but Miro's search feature is bad as hell. I search for something using MacTubes and it shows me 1600 results. The same search under Miro shows me 40 results. Miro never shows more than one page of results. I prefer it to be an application with a GUI, instead of command line, because my sister's proficiency in Linux is not that good. Any suggestions? Thanks.

• Typing Japanese on Windows Vista with Dvorak

  - by Ken

  I'm using Windows Vista, and I type English with the Dvorak keyboard layout, and I want to be able to type Japanese text that way, too. I've figured out how to set it up to let me type Japanese here, but it uses QWERTY. What I've got so far is: click the "EN" in the taskbar, and select "JP" if the letter that appears in the taskbar is "A", hit alt-~ to change it to "?" type as if I was typing Romaji on a QWERTY keyboard, (e.g., left pinky home row, right ring finger top row), and hiragana appear (??) press spacebar to convert to kanji (e.g., ?), and return to accept That all works great, but it assumes I'm on QWERTY, which isn't very comfortable for me. I want everything the same, but to be able to type kana with Dvorak (e.g., left pinky home row, left ring finger home row - ??). I can do this on Mac OS, so it's not an unheard-of feature. But it was kind of an obscure setting to find, so I figure on Windows it's probably a really obscure setting. :-) But I haven't been able to find it yet. Thanks!

• Backing up SQL NetApp Snapshots using TSM

  - by WerkkreW

  In our environment we have a 3 node SQL 2005 Cluster which is on NetApp storage. We are currently using SMSQL (NetApp SnapManager for SQL) to take Snapshot backups of the data. This works great, but due to some audit requirements we are also forced to maintain some copies on tape. We have used NDMP in other places across the enterprise but we do not want to use it in this specific instance. Basically what I need to do is, get the most recent snapshot copy of the databases on tape, via Tivoli Storage Manager (TSM). What I have done is, obtained a basic Windows Server 2003 VM with SnapDrive installed, which is SAN attached and zoned to the NetApp, and I have written a batch file to do the following: Mount the latest __RECENT snapshot lun to the host, using a specific drive letter Perform a TSM based incremental backup Dis-mount the LUN This seems to work fine, except sometimes the LUN's do not mount due to some sort of timeout. Also, due to my limited knowledge of windows batch scripting, I have no way to monitor the success or failure of these backups since I do not know how to send a valid return code back to the TSM scheduling service. Is there a more efficient/elegant way to accomplish this without NDMP?

• Building a Web proxy to get around same-origin restrictions for collaborative Webapp based on a MEAN stack

  - by Lew Cohen

  Can anyone point to books, articles, blogs, or even applications - open-source or proprietary - that detail building a Web proxy? This specific proxy will exist to get around the same-origin restrictions that prevent, for instance, loading a given Website into an <iframe> in a Webapp. This Webapp is a collaborative application in which a group of users log in to the app's Website and can then load different Websites into this app's <iframe> and do various collaborative things (e.g., several users simultaneously browsing a Website, in synch). The Webapp itself is built on a MEAN stack (MongoDB, Express, AngularJS, and Node.js). The purpose of this proxy is not to do anonymous browsing or to bypass censorship. Information on how to build such a vehicle seems not to be readily available from my research. I've come across Glype but am not sure whether this is a feasible solution. I don't want to reinvent the wheel, so if a product is available for purchase, great. Else, we'd need to build one. The one that seems to be close is http://www.corsproxy.com. In effect, we'd like to re-create this since it evidently does what's needed. I don't care what server-side technology is used. Our app is MEAN-based, if that has any bearing. Also, the proxy has to obviously honor basic security considerations (user cookies, etc.) and eventually be scalable. So, anyone know of any sources that would detail how to build one of these? Is it even worth building if something already exists? If so, what would be a good candidate? Any other issues that should be considered with this proxy/application? Thanks a lot!

• VPN Client solution

  - by realtek

  I have several VPN's that I need to establish on a daily basis but from multiple workstations. What I would like to do it have either a server or vpn router that can perform this connection itself and that I can then route traffic through this device or server depending on the subnet I am trying to reach. The issue is that I only use VPN Clients to connect, so I am basically trying to achieve almost a site to site VPN but by using basically a VPN Client type connection from my network. The main VPN Client I use is the Sonicwall Global VPN Client where I initially use a Preshared Key and then it always prompts me for a username and password (not RSA key). My question is, is there any type of linux distro or even a hardware vpn router that can do this and connect to a Sonicwall device as if it were a client? I have tried pfSense which is very good but it fails to connect, probably due to a mismatch of settings. I have tried many others. Even dd-wrt on my router but it does not support whatever protocol Sonicwall uses. (I thought L2TP/IPSec) but it appears it may not be that. Any advice would be great! The other other thing I have thought of that I have not tried yet is Windows Server Routing and Remote Access but I have a feeling that won't work either. Thanks

• How do I convert a video to GIF using ffmpeg, with reasonable quality?

  - by Kamil Hismatullin

  I'm converting .flv movie to .gif file with ffmpeg. ffmpeg -i input.flv -ss 00:00:00.000 -pix_fmt rgb24 -r 10 -s 320x240 -t 00:00:10.000 output.gif It works great, but output gif file has a very law quality.

• Affordable combined Ruby/Rails/Redmine + Subversion hosting?

  - by Pekka

  I'm a self employed web developer and after nine years of hard work, I'm looking to become a bit more "vagrant" starting next year, do some much-needed traveling and a bit and work off and on, making use of one of the greatest advantages of a programming job: The ability to work virtually from everywhere. For that, I am looking for a reliable hosting company I can entrust my code to in the form of a number of Subversion repositories, and an installation of the Redmine project management tool. As my financial situation may vary during traveling, I am looking for something I can pay up front for a year or two, and is obviously not too pricey. I don't care where the company is located, as long as it's trustworthy and solid, meaning it's not likely to go out of business next month. Does anybody know good recommendations? Preferably from own, personal, good experience. I have looked at CVSDude / Codesion and while they are certainly great, they don't offer Redmine of course, and seem to be aiming toward bigger organizations mainly. What I would need: 2-5 Gigs of space minimum, freely distributable between SVN, and Redmine attachments Unlimited number of Subversion projects Access control (team members / checkout-only accounts / etc.) I don't mind configuring the svn settings on file basis myself I need the possibility to map a custom domain to the package that is hosted elsewhere Frequent backups and access to those backups through FTP or other means I have been running my own virtual server for this until now, but I don't want the hassle, especially on the security side, while I may not always have the internet connection to fix problems that may come up.

• EC2: is an instance's public DNS stable? Can I rely on it not changing?

  - by Aseem Kishore

  I'm new to Amazon EC2. I've launched my first instance, and am using it as a web server. I see that it has a public DNS (a public URL), e.g.: ec2-123-45-6-789.compute-1.amazonaws.com I can successfully go to this server in my browser, hit it via cURL, etc. I want to use this web server for a back-end service in an app I'm building, so I placed this URL in my app's config, and it works great. But when I manually stop and re-started my instance, I see that the public DNS changes! I've read that this happens when you explicitly stop and re-start, but doesn't happen if you just "reboot". I don't plan on explicitly stopping and re-starting this server ever, but my question is: will this public DNS ever change on its own for any reason? E.g. if the machine abnormally crashes, or whatever. In other words, is it safe to ship an app that's wired to this URL? Thanks!

• Why does hiberfil.sys come back from the dead on Windows 7?

  - by Corey White

  I have Windows 7 running on a small (40GB) partition, with 4GB ram. This means that the hiberfil.sys file created by Hibernate takes up a significant portion of the available diskspace. I would like to remove it. I am aware that I can disable Hibernate and remove hiberfil.sys by entering powercfg -h off in an elevated command prompt. This works -- the file is immediately removed, and after doing so, the HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\HibernateEnabled key is (correctly) set to 0. However, the next time I reboot the PC, hiberfil.sys returns from the dead, Hibernate is reenabled, and that registry key has returned to 1. I'm pretty much at my wits' end with this. Almost everything I can find online related to removing the hiberfil.sys file simply suggests using powercfg to turn off hibernation, and that appears to work for just about everyone. But it just keeps coming back for me! (Like a vampire, sucking up my disk space.) I did find one other thread from someone who seems to have had the same issue, but none of the suggestions there worked for the original poster (or for me). Still, I have tried everything listed there, including: Disabling hybrid sleep Disabling Hibernate through the command prompt, through the Power Options GUI, and through both (in both orders) Manually changing the HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\HibernateEnabled key Pretty much everything else I can think of! I do want to reiterate that I have no problem removing the file -- that works great. It just comes back after every reboot. I'm about ready to throw in the towel and just run a script on login to disable Hibernate each time, even though that seems like a crazily hacky "solution" . . . but I was hoping someone here could suggest something else, first. Thanks!

• How many reverse proxies (nginx, haproxy) is too many?

  - by Alysum

  I'm setting up a HA (high availability) cluster using nginx, haproxy & apache. I've been reading great things about nginx and haproxy. People tend to choose one or the other but I like both. Haproxy is more flexible for load balancing than nginx's simple round robin (even with the upstream-fair patch). But I'd like to keep nginx for redirecting non-https to https among other things right at the point of entry to the cluster. On the other hand, nginx is a lot faster for serving static contents and would reduce the load on the powerful apache which loves to eat a lot of RAM! Here is my planned setup: Load balancer: nginx listens on port 80/443 and proxy_forwards to haproxy on 8080 on the same server to load balance between the multiple nodes. Nodes: nginx on the node listens to requests coming from haproxy on 8080, if the content is static, serve it. But if it's a backend script (in my case PHP), proxy forward to apache2 on the same node server listenning on a different port number. Technically this setup works but my concerns are whether having the requests going through several proxies is going to slow down requests? Most of the requests will be PHP requests as the backends are services (which means groing from nginx - haproxy - nginx - apache). Thoughts? Cheers

• Unattended Kickstart Install

  - by Eric

  I've looked around quite a bit and have seen similar setup and questions, but none seem to work for me. I'm using the following command to create a custom ISO: /usr/bin/livecd-creator --config=/usr/share/livecd-tools/test.ks --fslabel=TestAppliance --cache=/var/cache/live This works great and it creates the ISO with all of the packages and configs I want on it. My issue is that I want the install to be unattended. However, every time I start the CD, it asks for all of the info such as keyboard, time zone, root password, etc. These are my basic settings I have in my kickstart script prior to the packages section. cdrom install autopart autostep xconfig --startxonboot rootpw testpassword lang en_US.UTF-8 keyboard us timezone --utc America/New_York auth --useshadow --enablemd5 selinux --disabled services --enabled=iptables,rsyslog,sshd,ntpd,NetworkManager,network --disabled=sendmail,cups,firstboot,ip6tables clearpart --all So after looking around, I was told that I need to modify my isolinux.cfg file to either do "ks=http://X.X.X.X/location/to/test.ks" or "ks=cdrom:/test.ks". I've tried both methods and it still forces me to go through the install process. When I tail the apache logs on the server, I see that the ISO never even tries to get the file. Below are the exact syntax I'm trying on my isolinux.cfg file. label http menu label HTTP kernel vmlinuz0 append initrd=initrd0.img ks=http://192.168.56.101/files/test.ks ksdevice=eth0 label localks menu label LocalKS kernel vmlinuz0 append initrd=initrd0.img ks=cdrom:/test.ks label install0 menu label Install kernel vmlinuz0 append initrd=initrd0.img root=live:CDLABEL=PerimeterAppliance rootfstype=auto ro liveimg liveinst noswap rd_NO_LUKS rd_NO_MD rd_NO_DM menu default EOF_boot_menu The first 2 give me a "dracut: fatal: no or empty root=" error until I give it a root= option and then it just skips the kickstart completely. The last one is my default option that works fine, but just requires a lot of user input. Any help would be greatly appreciated.

• Bandwidth Suggestion

  - by Campo

  I have been asked to analyze the bandwidth usage of a company and make a recommendation for upgrading their Internet connection(s). Here is the layout 3 DLS lines so it is 3x(6 Down, 1 Up Each) into a load balancer out to the office's network. 30 VOIP phones run on a T1 (1.5 Down, 1.5 Up) The users at the company are heavily uploading. It is my suspicion that the issue in slowdown is being cause by multiple people uploading and others not being able to get requests out for even simple http requests. My initial idea is to get them a fiber line with a 10 down and 10 up. What do others think on this plan? Will that be enough to host their network traffic? What do I do about the VOIP line afterward? The fiber is expensive and I know the T1 does a great job for their VOIP so I do not want to suggest a DSL line because I know it may not be sufficient. I would also like to save them some money if I can. Maybe even get a faster fiber line and forgo the T1. Though I know their load balance/switch can only handle 20MB/S throughput. Looking for some confirmation/suggestions on my plan. I am planning on going in to get some real diagnostic numbers. Any suggestions on software to use for that? Preferably Windows software.

• How do I stop panning on a monitor that supports a specific resolution?

  - by IronicMuffin

  Hi all, I've been battling this for a few days now. Any and all help is appreciated. I have a planar monitor with a native res of 1280x1024. At one point, I had used PowerStrip to override "something" and set the res to 1600x1200, and it worked great. I then installed new intel graphics drivers for my 86895g (or w/e model) video card, which screwed up whatever settings I had. If I set it to 1600x1200 this time, it would set the res correctly, but give me a 1280x1024 viewport and the screen would pan when the mouse got to the edges of the screen. Absolutely not useful. Ok, so I was limited to 1280x1024 now. W/e. Now...enter new video card with two video ports. I have two monitors now and the latest nVidia drivers. I decide to try to get dual 1600x1200 going...ended up screwing the original monitor up so much now that it's at 1280x1024, with a 1024x768 viewport and panning! Absolutely not usable now. So what I need, and I can't seem to find on any forums, is help doing one or more of the following: Clearing out all monitor/edid info out of the windows registry without corrupting the registry. Actually correctly override the EDID values and get my sweet res back. Some other way of getting back to at least dual 1280x1024 with NO panning. Note: My device manager shows 4 monitors for some reason. My registry shows entries for all sorts of monitors that have been hooked up to the machine over the years. It's making it difficult to debug. Experience with PowerStrip would be helpful. I've been mucking with Phoenix EDID designer and MonInfo as well, but I'm stumbling around in the dark with these. Windows XP SP2 nVidia GeForce 6200 nVidia drivers: v258.96 Monitor: Planar PL 1910M Thanks!

• Laptop battery holds charge, but won't charge any more.

  - by Jeff

  Ok, I'm sure I will need to replace either my battery or my AC adapter, but would rather not buy one if the other is the problem. My problem is. I have a Sager laptop that gets quite a bit of use. The charging has always been a little bit odd. If I was in the process of using it, it would charge just fine and stay On AC power. If I left it alone, however(power settings to ONLY turn off the monitor) in either Ubuntu or Windows 7 it decides that it didn't want to use AC power anymore and would just start draining the battery until it died. Now, suddenly, it won't charge at all. The capacity was great up to this point which happened in an instant. It will recognize the battery but won't see the AC power if plugged in while the battery is in. I can power up the laptop without the battery and it works fine. If I plug in the battery while powered up it will claim it's charging it, but it stays at the same percentage. If I unplug the power, it will switch over to Battery fine, but I have to power down and unplug the battery to get it back on AC power. I've had dying/dead batteries before but they typically won't hold a full charge anymore but it still winds up to 100% then drops quickly when unplugged. This seems more like a chip problem in the battery to me, but I'm not sure. Any ideas?

• Copy files from sub directories into one directory.

So my plan is to first cp all 2011-01-07 sql files into a tmp dir e.g. cp /backup/daily/*/*2011-01-07*.sql /tmp/all The command above unfortunately isn't working I get an error: cp: cannot stat ..... No such file or directory So can you guys help me out with this. For bonus points if you can tell me how to do the next step which is import all databases in one command doing one at a time that would be great too. I really want to do these in two separate steps because I need to delete a few sql files manually from the tmp dir before I run the restore command. So I need: 1) command to copy all 2011-01-07 sql files to a tmp dir 2) command to import all those files in that dir into mysql I know its possible to do in one but for lots of reasons I really would prefer to do it in two steps.

• Can I get all active directory passwords in clear text using reversible encryption?

  - by christian123

  EDIT: Can anybody actually answer the question? Thanks, I don't need no audit trail, I WILL know all the passwords and users can't change them and I will continue to do so. This is not for hacking! We recently migrated away from a old and rusty Linux/Samba domain to an active directory. We had a custom little interface to manage accounts there. It always stored the passwords of all users and all service accounts in cleartext in a secure location (Of course, many of you will certainly not think of this a being secure, but without real exploits nobody could read that) and disabled password changing on the samba domain controller. In addition, no user can ever select his own passwords, we create them using pwgen. We don't change them every 40 days or so, but only every 2 years to reward employees for really learning them and NOT writing them down. We need the passwords to e.g. go into user accounts and modify settings that are too complicated for group policies or to help users. These might certainly be controversial policies, but I want to continue them on AD. Now I save new accounts and their PWGEN-generated (pwgen creates nice sounding random words with nice amounts of vowels, consonants and numbers) manually into the old text-file that the old scripts used to maintain automatically. How can I get this functionality back in AD? I see that there is "reversible encryption" in AD accounts, probably for challenge response authentication systems that need the cleartext password stored on the server. Is there a script that displays all these passwords? That would be great. (Again: I trust my DC not to be compromised.) Or can I have a plugin into AD users&computers that gets a notification of every new password and stores it into a file? On clients that is possible with GINA-dlls, they can get notified about passwords and get the cleartext.

• Can I convert an existing Firefox installation to ESR without a re-install?

  - by Iszi

  It took some jumping through hoops (including a mailing list subscription that I apparently didn't need) but I finally found where to download the Firefox ESR. This is great for fresh installs, but I was wondering if there's a way to simply convert existing installations to the ESR configuration without having to do a full install. As I understand it, the only difference between ESR and regular Firefox will be how they receive updates. After the new standard version of Firefox comes out, ESR releases will only receive critical security updates and bug fixes for the remainder of their support life. Newer versions of Firefox's standard build will have all the latest and greatest features, while ESR releases are meant to provide stability for environments that can't be expected to keep up with a new full version number change as often as Mozilla does them. In regular Firefox, the About screen shows that I am using the "release" update channel. Is switching to ESR really just a matter of switching the update channel? I presume this can be done in about:config by changing app.update.channel and probably also app.update.url. However, I don't know what these values should be for ESR or if anything else should be tweaked. So, is it possible to switch to ESR without a reinstall and, if so, how? (Note: While this question was written originally for Firefox 10, I expect any answers will apply to future ESR versions as well.)

• Monitor goes black for a few seconds

  - by privatehuff

  I have a Hanns G 28" monitor, Model # HG281D It has its issues (viewing angle sucks) but has been functional and solid, great for desktop stuff. Worked without any sign of any problems for 6-12 months. However, now the monitor "goes black" for about 2-3 seconds, almost like when you click "detect display" It does not turn off (power light does not go amber) The computer is completely unaffected and the video mode never changes when the picture returns. The computer is fully responsive and will keep playing music or taking my keypresses during the time I can't see anything. (it just happened and I kept typing, etc) It happens on multiple computers across several operating systems. (I have an 8-port iogear KVM switch that has several computers connected) But, it seems to happen only on certain computers. I have a hackintosh that does it, a windows 7 PC that does not, a lenovo laptop that does not, and my old ubuntu 8.10 box did not do it, but my new mint 8 box does do it. I've check the connections and tried changing out the power cable and the vga cable. Sometimes it won't happen for hours (or days) and sometimes it happens several times per hour. It was happening many months ago, did not happen for months, and has now started happening again. Does this make any sense? What could it be?

• What's next for all of these Microsoft "overlapping" and "enhanced" products ?

  - by indyvoyage

  Recently I attended a road show, organised by MS Gold Partner company in the UK. The products discussed were: SharePoint server (2010 and 2007), Exchange server, Office Communication Server 2007, Exchange hosted services Office Live meeting, Office Communicator, System Center Configuration Manager and Operation Manager, VMware, Windows 7 etc. As Microsoft claims the enhancement in the each product against higher version, I felt that clients are not much interested in all these details. For example Office Communicator, surely they have improved a lot the product and first site all said 'WOW' great product, but nobody wish to pay money for all these extra features. Some argued, they are bogged down by all these increased number of menus. They don't need soft call feature included with mobile call. It apply for all other products as well such as MS office (next what 2 ribbons ?), windows OS and many more. Indeed there must be good features in all these products, but is it worth to spend money and time to update the older system ? Also sometimes these feature will decrease the productivity instead increase it. *So do you think what ever enhancement MS is doing in the products is only for selling purpose, not a real use ?? and I think also keep the developer busy learning the new tools and features. * I am sure some some people here will argue that some people need this sort of features. But I am not talking about NASA or MI5 guys. I am talking of usual businesses and joe public. Any ideas welcome.

• Looking for "bitmap-vector" image editor

  - by Borek

  I used to use PhotoImpact which is no longer developed so I'm looking for a replacement. What made PhotoImpact great to me was the ability to work in both bitmap and vector modes. What I mean by that: I could have an image or screenshot and easily add arrows, text captions or shapes to it. These shapes were vector objects so I could come back to them later and amend their properties easily. Software I know of: Paint.NET is purely bitmap so please don't recommend it - layers are not enough for my needs Drawing tools in MS Office work pretty much the way I'd like - you can paste an image and then add vector objects on top of it. It just doesn't feel right to have the full-fidelity original images stored as .docx or .pptx (I don't fully trust Word/Powerpoint that they don't compress the image) I'm not sure about GIMP but if it's just "better Paint.NET" (i.e., layers but no vector objects) I'm not interested Photoshop is out of question purely because of its price tag Corel killed PhotoImpact because they already had a competing product (Paint Shop Pro) but AFAIK it lacks vector features. Any tips for PhotoImpact alternatives would be very welcome.

• Ubuntu NBR karmic boot freezes at fsck from util-linux-ng 2.16

  - by Bluebill

  I have a netbook (emachine e250 - equivalent to an acer aspire one) and I have Ubunutu NBR 9.10 installed on it. Every other cold boot freezes at the following error message: fsck from util-linux-ng 2.16 There is no disk activity, no activity what so ever. I have left the machine sit for over an hour and nothing. It takes a couple of hard resets to be able to boot properly. Once it boots everything works great (wireless, suspend/resume, etc.)! I have spent the last couple of weeks researching the problem and the only thing that seems to work is setting nolapic in the boot string in grub - it boots every time. Unfortunately, nolapic disables the second core and causes problems with suspend resume. At first I thought it was an fsck problem with the first partition on the hard disk as it is a hidden ntfs partition containing the windows xp recover information. So in /etc/fstab I set the partition so that it would be ignored by fsck. This didn't seem to do anything. I have these partitions: /dev/sda1 - an ntfs recovery partition /dev/sda2 - /boot /dev/sda3 - swap /dev/sda5 - / /dev/sda6 - /home I am running kernel version 2.6.31-19-generic and have all the patches (as indicated by update manager). I also have no splash screen so I can see the boot progress. I have only been using NBR since January, I have been using Ubuntu on my desktop since last June (2009-06). What logs should I be looking at? Is there a log for failed boots?
