• Which e-reader for O'Reilly books?

  - by Tim

  Most of my programming books are from O'Reilly. Several of them need to be updated, and I'm thinking of going for an e-reader this time. O'Reilly sell their e-books as a multi-format bundle (PDF, EPUB and Mobipocket (Kindle)). Has anyone done a comparison of the formats as for suitability on a small e-reader screen? In Europe, the Kindle DX is not (yet?) available, so I'm not sure whether a Kindle or a Sony (or some other reader) is best suited for these books. Disregarding other advantages/disadvantages of the different readers for now, which one in your opinion gives the best experience with O'Reilly books in particular (or programming books in general)?

• acessing a subnetwork from within a vm

  - by yan bellavance

  I have a pc running windows 7. I have vmwareplayer running RHEL5 I have 1 physical ethernet connection. this ethernet connection is wired to a hub. there is another device on that hub that needs to be in a certain subnetwork (192.168.0.xxx)(lets call him device X) but the general network is 192.168.1.xxx How can I configure the network adapters so that I can ping device X from RHEL5 in the vm. Originally I could ping google from both windows and rhel (I was in the .1 network) but not device X since he is on a different subnetwork address. Now that I have put it on the .0 I can ping device X from windows but not from rhel5 and cannot access the web. I did this by manually setting the IP address.

• Windows Experience Index could not be computed

  - by Alexey Ivanov

  I've upgraded recently from Windows Vista to Windows 8. When I try to rate my computer, it accesses DirectX 9 performance, then processes to DirectX 10 tests: And it gets stuck at this point. In 5–10 minutes, it shows error message: The video card is rather old: Mobile Intel 965 Express Chipset Family. I'm pretty sure it does not support DirectX 10. Why does Windows assess it with DirectX 10? And how can I make it skip DirectX 10 tests and get the system rating? The driver was installed automatically by Windows 8 from Windows Update. Version: 8.15.10.2697 Date: 10/01/2012

• serving static assets via http is really slow compared to sshfs (apache2/nginx)

  - by s1lv3r

  After migrating to a new VPS I had some users complaining about slow loading images on their sites. After creating some test files with dd I realized that I can download all files via sshfs with full speed while downloads via web are painfully slow. The larger the file is and the longer the transfer takes, the slower the transfer speed gets. I thought I had some problems with Apache and just spend the whole evening with replacing Apache2 against nginx for static file serving - with no effect at all. No I/O wait states in top. Tons of RAM free, no high CPU utilization and hdparm shows a decent I/O performance at all times. I just have no idea anymore, what's happening on this server. This is a link to a demo file: http://master.dealux.de/file.tgz Anybody an idea what I can check out?

• VMware Workstation 9 Security Best Practice Guides

  - by slickboy

  Could someone please point me in the direction of where I could find some best practice securiy guides for VMware Workstation 9 please? I've searched the VMware site and to say it's badly organised is an understatement! I've been able to find general setup guides but nothing with a specific focus on security. I'm also wondering is there any best practice guides that I should follow when installing Windows 7 Professional and Windows Server 2008 R2 on VMware Workstation 9? I obviously will be implementing Microsofts recommended security best practices but I'd be very interested in any recommendations for virtualizing these operating systems. Any help is much appreciated.

• Drivers for Quick Cam pro 9000 on Windows 7

  - by runaros

  I have a Logitect Quick Cam Pro 9000 that I want to install on my Windows 7 installation. The user manual specifies that I have to install the software before I install the camera. But my experience is that software from hardware vendors tend to decrease computer performance, so I was wondering if this camera will work by only plugging it in and letting Windows 7 find and install the drivers for it. I could've just tried installing it of course, but again, hardware vendors are notorius for fucking up things, and I wouldn't want to make it impossible to install the camera by doing things in the wrong order, hence the question here on SuperUser because I assume somebody is more knowledgeable than me on this subject.

• Rip authedicatation from LDAP to Local

  - by oxinabox

  We are taking a small portion of out network offline, and running a separate network using that portion. (By small portion I mean 2 servers, that will be connected to 30 odd boxs that aren't usually part of our network, and don't need to authenicate) I intend to create a VM on one of the servers to provide general user services, and IRC server, remote shell etc. And I would like the users to be able to use there usual server log in details. Problem is the LDAP server that normally checks those details is not one of the severs. So I need to be able to some how take their details off LDAP and put them on the the server that is coming. One suggestion I had was to set a LDAP server on the VM locally, and clone the LDAP database onto it (using something called slapcat) is this the best way? Or can I I change the LDAP data into local authentication data?

• Unable to Get IIS Response Times with Hyperic Monitoring Tool

  - by jwmajors81

  We have a very large .NET application (vendor) that I am trying to gather performance metrics for using Hyperic. In general I wanted to be able to report response times for each of the components within the application, which include: Web Services ASP.NET Pages MSMQ I am currently unable to successfully monitor the response times for IIS on my windows machines. I have successfully auto-discovered them and I am getting diagnostic information, but am not getting back the response times. After looking online at what other people are seeing, I found that I am missing a tab for the response times which is usually next to the metrics tab. Also, when I look at the configuration screen for IIS I do not see a field which enables me to specify where the log files are located at. Please note that my logs are located at e:\LogFiles\ instead of the usual location because our IT staff doesn't allocate much space for the C: drive. Please note that I have the MSMQ monitors up and running great. Any assistance would be greatly appreciated. Thanks, Jeremy

• A minimal Linux distribution for my ASUS EEE PC

  - by Andrioid

  I recently bought myself a ASUS EEE 1000HE and I intend to use it for note-taking and light browsing at the University. The machine has a 10" screen so the interface needs to be very compact. I've already tried: EEEbuntu: Very nice driver support and out of the box experience. But I feel that it is too slow booting and the general experience is too heavy in my opinion. Moblin 2: Looks very cool, boots just fine but is way too unstable to use. Also find it annoying that I can't find hotkey documentation anywhere. Any Netbook OS recommendation welcome (although those specific to my model would be great). There is an entire jungle of distributions out there, so if you've been on a safari, please share your experience.

• "svn: Cannot negotiate authentication mechanism" for OSX CLI and WinXp TortoiseSVN, but linux CLI works

  - by dacracot

  I had a working subversion server which used the passwd file which stores passwords in clear text. My requirements changed so that passwords now need to be encrypted. I did everything according to the book to use SASL, or so I believe, but now only the linux command line can authenticate. My OSX users, which also use command line, and my WinXp users, which use TortoiseSVN get errors. Linux versions are 1.6.11. OSX versions are 1.6.17. And TortoiseSVN versions are 1.7.4. /opt/subversion/QRpage/conf/svnserve.conf: [general] anon-access = none auth-access = write realm = ABC [sasl] use-sasl = true min-encryption = 128 max-encryption = 256 /etc/sasl2/svn.conf: pwcheck_method: auxprop auxprop_plugin: sasldb sasldb_path: /etc/sasldb2 mech_list: DIGEST-MD5 Then I add new users via: saslpasswd2 -c -f /etc/sasldb2 -u ABC dacracot But for instance OSX users get this error trying to check out: $ svn co svn://svn.nowhere.org/QRpage svn: Cannot negotiate authentication mechanism

• Unmounting a zfs pool while it is shared with sharenfs

  - by Ted W.

  I have a Solaris (open indiana) system which is getting poor disk write performance. In order to enable ZIL in this version of zfs I need to add a line to /etc/system. This will not take affect until I've unmounted and remounted the zpool. The trick is that this spool is shared via nfs to about 200 other servers to host users' home directories. I can guarantee that no users will be accessing the disks during this period of maintenance but I would like to avoid having to issue an unmount for 200 systems in order to unmount the disk on the Solaris box. My question is, with sharenfs, is it necessary to have all systems disconnected before unmounting the filesystem on the host? If it's possible, how do you go about it? I've tried unmounting already, the normal way, and it reports the disk is busy. There is no lsof in Solaris and pfiles (I think that's what it was) does not show anything obviously using the mounts.

• Windows authentication through IE - specify the domain

  - by Chris W

  This question really relates to allowing to logon to a SharePoint installation from home but I guess it's a general IIS security question. When the login box pops up to collect the windows credentials the user can just type in their user name on Safari/Chrome/FF and they can login correctly. On IE authentication fails as it seems to pass their local machine name by default and the user needs to replace this with domain\user. Not a big problem in some cases but we'd prefer it if the users didn't have to enter the domain name portion. Is this simply a feature of IE that we can't control or is their something we can do with IIS/AD etc that will allow us to provide a default domain if one isn't specified?

• IT Audit checklist

  - by PHLiGHT

  I recently have taken on the position of a one man show for a company that is going to have an audit. The network isn't anywhere close to prepared and I have been looking for a general audit checklist since one hasn't been provided by the auditors and haven't found much good information out there. Does anyone have a nice template that will give me a good starting point. I know that this will be highly customized to the company but a starting point will be helpful to outline to management just how much work is needed. Thanks,

• Asus V1S/V1V inverter cable

  - by Bill

  I have an Asus V1V, which is the same as the Asus V1S except for the video card. I have a problem where the screen will randomly lose brightness or flicker between being lit and not lit. The picture below is of the left hinge, with the cover removed. Pressing one of these cables affects this behaviour, and pressing it in place will resolve the issue for a few hours. To me this means the inverter cable is damaged. As the picture shows, there are two cables, an LCD cable and what I assume is an inverter cable. I purchased an LCD cable for my model of laptop, but have been unable to find an inverter cable. It seems not to exist. I would like some input on if an inverter cable actually exists, if it is likely the problem, or solutions in general to resolve this problem permanently.

• size of extent on LVM2

  - by piotrek

  in LVM1 there was a limit of 65k extends. So size of extent had to been chosen carefully between wasted space on partitions (to big extent) and maximal possible size of logical volume (too small extent). in lvm2 (according to http://docstore.mik.ua/manuals/hp-ux/en/5992-4589/apa.html) the limit is ~16 million extents. so the default size of 4mb gives ~60TB of LV size. so is there any point in making the extent larger than 4-16mb on a desktop? is there any performance degradation or other costs of having big number of extents?

• Best choice for off-site backup: dd vs tar

  - by plok

  I have two 1TB single-partition hard disks configured as RAID1, of which I would like to make an off-site backup on a third disk, which I am still to buy. The idea is to store the backup at a relative's house, considerably far away from my place, in the hope that all the information will be safe in the case of a global thermonuclear apocalypse. Of course, this backup would be well encrypted. What I still have to decide is whether I am going to simply tar the entire partition or, instead, use dd to create an image of the disks. Is there any non-trivial difference between these two approaches that I could be overlooking? This off-site backup would be updated no more than two or three times a year, in the best of the cases, so performance should not be a factor to be pondered at all. What, and why, would you use if you were me? dd, tar, or a third option?

• Cheap windows shared hosting service

  - by Elangovan

  Hi I have recently purchased a domain from go daddy, now I am looking for a cheap windows hosting. Following are my requirements Shared Windows hosting Should be cheap in price Should have at least one SQL server Db and one mysql db. Should support atleast asp.net 3.5 and php Will be good if it has support for asp.net mvc (no problem even if it is not available also) Should be able to install third party blog sites. Bandwidth, total space and performance are not very important. Silverlight is also an added advantage (no problem even if it is not available also). There should be no advertisement or banner added by the hosting company in the site. Should have support for subdomains

• Worth it to move /var to physical disk vs logical?

  - by Tammer Ibrahim

  Brief question about partition layout. I use an SSD for /, /boot, /usr, & /home partitions. I'd like to move /var to a mechanical disk to minimize writes to the SSD. I'm mainly concerned about maximizing drive life rather than maximizing performance (although I obviously wouldn't want to cripple my server). My mechanical disks consist of two drives sharing LVM, and a third used for nightly rsync backups. I also have a bunch of old 2.5in hard disks lying around. My question is, should I simply create a new LVM volume '/var' on my primary data store, or would it be worth the increased energy consumption (in terms of maximizing the lifetime of the LVMed drives) to install a low volume 2.5in disk to use just for /var? On a more general level my question is about the trade offs of placing OS mounts on the same physical volumes as my data. Thanks for any help!

• Debian based OS: Show system notification on clipboard copy/paste events

  - by ifischer

  When working with Linux (Debian based), I often experience problems in relation to the copy paste commands: I copy something with Ctrl+C or by selecting it with the mouse, but when I try to paste it somewhere else, the clipboard is empty and nothing happens - whatever reason caused this. This annoys me, as I have to switch to the source application again and again copy the text. So to really be sure if something was copied into the clipboard I would like it if the window manager (be it Gnome, KDE, etc) would show a Desktop Notification (for example powered by libnotify) as soon as anything is copied into the clipboard, showing the content that has been copied into the clipboard. Is that possible by using one of the many clipboard managers out there (glippy, clipit, ...)? If not, can I write a (DBus?)-hook, which is triggered during copy-to-clipboard-actions, showing the content which is to copy inside the Desktop Notification? (The latter approach would be more interesting, since I'm interested in hooking into system events in general)

• laptop overheating ran defraggler and now its not as hot

  - by Marko

  Trying to diagnose and fix an overheating Acer 5735 laptop, running speedfan and doing general workload to try and cause the overheat conditions. I notice that windows xp is badly fragmented according to defraggler, at 58% fragmentation. So I defrag whilst watching the speedfan window, which was at the start reporting high warning style symbols for all of the sensors. After the defrag, I rebooted and ran a few programs, and even defraggler again and the sensors in speedfan all reported green i.e. not high. Wondering if there is a correlation between windows fragmentation causing the hard drive to work harder and produce more heat inside the laptop? dont want to just assume that the problems are resolved, so either speedfan is not accurate enough or fragmentation can lead to additional hard drive heat? All comments or suggestions welcome.

• Unable to connect to sites using IIS7 Manager

  - by Phil.Wheeler

  I'm a developer who has been assigned the task of managing and configuring a new IIS7 instance on a remote server. My domain account has been added as to the local Administrators group on the box, but IIS7 has been configured to accept connections only from accounts with Windows credentials. I've added my domain account to the IIS Manager Permissions for one of my sites, but I'm still unable to connect to either that site, the IIS instance or the server in general from my local machine. There's obviously a missing element to the configuration of this setup but I don't know where to start looking. The event logs on the IIS box show audit failures for my account when trying to connect remote via the IIS7 Manager tool on my local machine. Suggestions gratefully received.

• windows server 2008 vs ubuntu 11 [closed]

  - by user472875

  I am working on implementing a custom server application that should be capable of handling a very large volume of traffic. I am aware that this type of question has been asked a lot, but I haven't been able to find a good answer. What I'm really looking for is for a server with given specs which OS will be able to handle a larger traffic faster and more reliably. I do not care about rights management or any other features. I am fairly good with both platforms, and so I would like to pick the OS with better performance on a clean install, and with nothing else running. Thanks in advance.

• Server 2008 Hard Faults

  - by claw

  Hey all, plase bear with me as I haven't looked at a server in a very long time. The problem I am having is with a Windows 2008 Standard FE Service Pack 2 Intel Xeon X3430 @ 2.40 2.39 GHZ 4 GB Memory 64 Bit There seems to be no problems other than the physical memory peaking at 91%, always with over 100 Hard Faults Per Second. To my understanding hard faults should be fairly rare on a machine with. Are there any logs I can show you? Or investigate myself. The general performance of the machine is ok, i can access SBS2008 and change settings fairly smoothly without hangs etc. However, we connect to the server and do quite a bit of SQL via an application. For a record to retrieve say 20 rows, it can take 20+ seconds. Thanks in advance, Jamie EDIT: What the server is used for: IIS ASP Web Service SQL 2008 List item Exchange unable to upload screenshots due to low reputation - why doesnt my SO work here :)

• HTTP 401 Challenge and HTTP 302 Login/Redirect won't work together in IIS7

  - by RandomBen

  I am developing a website using .NET 3.5 that allow users to visit the site and create logins using the standard Microsoft login controls. However, users do not need to login to do general things like view products. Now I need to setup the site so some of our Traveling Sales people are able to access it but not allow anyone else to access it. The easiest way I know how to do this is to turn on Windows Authentication for the Site in IIS7. When I do that I get all sorts of errors due to also having Forms Authentication turned on. If I turn Forms Auth then I get a different kind of error. Does anyone know how to make Forms Auth and Windows Auth play nice on a single site in IIS7 or some other way to create a required login without having me kill Forms Auth?

• What does the "Maximum Frequency" number mean in the Windows Resource Monitor?

  - by nhinkle

  In the Windows Resource Monitor's CPU tab, there is a status box and graph for the "Maximum Frequency", right next to the "CPU Usage" values. What does this mean? The value is sometimes over 100% on my system... what could that imply? By looking at CPU-z's real-time report of the processor's clock speed, it seems to be loosely related to what frequency the CPU is running at, which would imply that it means "percent of maximum possible frequency the CPU is running at"; this would be of relevance on systems with SpeedStep and/or TurboBoost technology (or similar). Furthermore, setting the system to "power saving mode" lowers the "maximum frequency" value to around 60%, while setting it to "high performance" mode sets it to around 110%. However, the percentage does not seem to exactly correlate to the CPU speed being shown. What value is this actually representing then?
