• Installing Ubuntu 12.10 on new computer with Windows 8

  - by rft183

  I recently purchased a new HP computer (P6-2330) with Windows 8. I have tried unsuccessfully to install Ubuntu 12.10 64bit alongside Windows 8. The computer is UEFI with Secure Boot enabled. I've tried following the instruction at https://help.ubuntu.com/community/UEFI. I am able to get the GRUB menu to show up. However, as soon as I press Enter on either Try Ubuntu or Install Ubuntu, the screen goes blank. Nothing works at all, not even the Num Lock or Caps Lock keys on the keyboard. I have to use the power button to restart the computer. Does anyone have any suggestions on how to get Ubuntu installed? To clarify, I have actually tried installing using both a USB stick and a DVD. The USB stick gave a blank screen, while the DVD gave the error message "Empty Security Header" after pressing Enter at the GRUB screen.

• Public Cloud, co-location and managed services ... what is the cloud?

  - by llaszews

  Recently I have had conversation with a number of people that are selling and implementing 'cloud' solutions. I put cloud in quotes as implementations like co-location (aka co-lo) and managed services (sometimes referred to as 'your mess for less') have become popular options for companies moving to the cloud. These are obviously not pure public cloud offerings and probably more of hybrid cloud implementations as the infrastructure (PasS and IaaS)is dedicated to a specific customer. This eliminates the security, multi-tenancy, performance and other concerns that companies have regarding public cloud. Are co-location and managed services cloud to you? Are they something your company is considering when you think about cloud ?

• How to run a file with sudo without a password?

  - by John

  I've made a script that preforms various system tasks, that I run regularly, but I have to use sudo to run the script, despite the fact that I own it because it runs root privileged commands. How can I add make sudo let me run this one file without having to enter my password every time I run it? I know that there are questions regarding running commands without a password, but I wasn't able to find one on running a file without a password. I am aware of the security risks, but I'm at home on a computer that I trust.

• Different Not Automatically Implies Better

  - by Alois Kraus

  Originally posted on: http://geekswithblogs.net/akraus1/archive/2013/11/05/154556.aspxRecently I was digging deeper why some WCF hosted workflow application did consume quite a lot of memory although it did basically only load a xaml workflow. The first tool of choice is Process Explorer or even better Process Hacker (has more options and the best feature copy&paste does work). The three most important numbers of a process with regards to memory are Working Set, Private Working Set and Private Bytes. Working set is the currently consumed physical memory (parts can be shared between processes e.g. loaded dlls which are read only) Private Working Set is the physical memory needed by this process which is not shareable Private Bytes is the number of non shareable which is only visible in the current process (e.g. all new, malloc, VirtualAlloc calls do create private bytes) When you have a bigger workflow it can consume under 64 bit easily 500MB for a 1-2 MB xaml file. This does not look very scalable. Under 64 bit the issue is excessive private bytes consumption and not the managed heap. The picture is quite different for 32 bit which looks a bit strange but it seems that the hosted VB compiler is a lot less memory hungry under 32 bit. I did try to repro the issue with a medium sized xaml file (400KB) which does contain 1000 variables and 1000 if which can be represented by C# code like this: string Var1; string Var2; ... string Var1000; if (!String.IsNullOrEmpty(Var1) ) { Console.WriteLine(“Var1”); } if (!String.IsNullOrEmpty(Var2) ) { Console.WriteLine(“Var2”); } ....   Since WF is based on VB.NET expressions you are bound to the hosted VB.NET compiler which does result in (x64) 140 MB of private bytes which is ca. 140 KB for each if clause which is quite a lot if you think about the actually present functionality. But there is hope. .NET 4.5 does allow now C# expressions for WF which is a major step forward for all C# lovers. I did create some simple patcher to “cross compile” my xaml to C# expressions. Lets look at the result: C# Expressions VB Expressions x86 x86 On my home machine I have only 32 bit which gives you quite exactly half of the memory consumption under 64 bit. C# expressions are 10 times more memory hungry than VB.NET expressions! I wanted to do more with less memory but instead it did consume a magnitude more memory. That is surprising to say the least. The workflow does initialize in about the same time under x64 and x86 where the VB code does it in 2s whereas the C# version needs 18s. Also nearly ten times slower. That is a too high price to pay for any bigger sized xaml workflow to convert from VB.NET to C# expressions. If I do reduce the number of expressions to 500 then it does need 400MB which is about half of the memory. It seems that the cost per if does rise linear with the number of total expressions in a xaml workflow.  Expression Language Cost per IF Startup Time C# 1000 Ifs x64 1,5 MB 18s C# 500 Ifs x64 750 KB 9s VB 1000 Ifs x64 140 KB 2s VB 500 Ifs x64 70 KB 1s Now we can directly compare two MS implementations. It is clear that the VB.NET compiler uses the same underlying structure but it has much higher offset compared to the highly inefficient C# expression compiler. I have filed a connect bug here with a harsher wording about recent advances in memory consumption. The funniest thing is that one MS employee did give an Azure AppFabric demo around early 2011 which was so slow that he needed to investigate with xperf. He was after startup time and the call stacks with regards to VB.NET expression compilation were remarkably similar. In fact I only found this post by googling for parts of my call stacks. … “C# expressions will be coming soon to WF, and that will have different performance characteristics than VB” … What did he know Jan 2011 what I did no know until today? ;-). He knew that C# expression will come but that they will not be automatically have better footprint. It is about time to fix that. In its current state C# expressions are not usable for bigger workflows. That also explains the headline for today. You can cheat startup time by prestarting workflows so that the demo looks nice and snappy but it does hurt scalability a lot since you do need much more memory than necessary. I did find the stacks by enabling virtual allocation tracking within XPerf which is still the best tool out there. But first you need to look at your process to check where the memory is hiding: For the C# Expression compiler you do not need xperf. You can directly dump the managed heap and check with a profiler of your choice. But if the allocations are happening on the Private Data ( VirtualAlloc ) you can find it with xperf. There is a nice video on channel 9 explaining VirtualAlloc tracking it in greater detail. If your data allocations are on the Heap it does mean that the C/C++ runtime did create a heap for you where all malloc, new calls do allocate from it. You can enable heap tracing with xperf and full call stack support as well which is doable via xperf like it is shown also on channel 9. Or you can use WPRUI directly: To make “Heap Usage” it work you need to set for your executable the tracing flags (before you start it). For example devenv.exe HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\devenv.exe DWORD TracingFlags 1 Do not forget to disable it after you did complete profiling the process or it will impact the startup time quite a lot. You can with xperf attach directly to a running process and collect heap allocation information from a gone wild process. Very handy if you need to find out what a process was doing which has arrived in a funny state. “VirtualAlloc usage” does work without explicitly enabling stuff for a specific process and is always on machine wide. I had issues on my Windows 7 machines with the call stack collection and the latest Windows 8.1 Performance Toolkit. I was told that WPA from Windows 8.0 should work fine but I do not want to downgrade.

• SSL certificates - best bang for your buck [closed]

  - by Dunnie

  I am in the process of setting up an online store. This is the first project I have attempted which will require a good level of security, so I recognise that an decent SSL certificate is a must. My current (albeit admittedly basic) understanding of the options are: DV SSL - more or less pointless, as provides no verification. OV SSL - better, as provides a basic level of organisational verification. EV SSL - 'better, full' verification, but much more expensive. As this is a new business venture, and budgets are tight, which option provides the best bang for my buck? I have read questions such as EV SSL Certificates - does anyone care? which suggest that EV certificates are a bit of a con. Does this mean that OV certificates offer better value for money, especially for new businesses with shallow pockets?

• forward sudo verification

  - by Timo Kluck

  I often use the following construct for building and installing a tarball: sudo -v && make && sudo make install which will allow me to enter my password immediately and have everything done unattended. This works well except in the rare case that building takes longer than the sudo timeout, which may happen on my rather slow machine with large projects (even when using make -j4). But when the build takes a long time, that's exactly when doing things unattended has a great advantage. Can anyone think of a shell construct that allows me to input my password immediately, and which has make executing under normal permissions and make install under elevated permissions? For security reasons, I don't want to configure my user to use sudo without password. A viable option is to set the timeout to very long, but I'm hoping for something more elegant.

• What factors influence you to try out a new framework or tool?

  - by VirtuosiMedia

  I'm in the process of putting the final touches on an open-source framework that I hope to release in the next few months. It's something that I'd like to develop a community for and so I'm curious about what factors influence your decision to use a new framework or tool and why. Some of the specific things I'd like to know more about (feel free to add to this): Types of documentation/tutorials/instruction Community support (comments/forum) Updates (blog/social media/feeds) Look and feel of the project website design White papers/testimonials A big feature list Community size Tools Ability to contribute Project test coverage (stability/security) Level of buzz (recommended by friends or around the web) Convincing marketing copy Ideally, I'd like to have all of the above, but what specific features/qualities will carry greater weight in getting programmers to adopt something new? What says, 'This is a professional-grade project,' and what are red flags that keep you from trying it out?

• SQL Server 2008 R2: StreamInsight changes at RTM: Event Flow Debugger and Management Interface Secur

  - by Greg Low

  In CTP3, I found setting up the StreamInsight Event Flow Debugger fairly easy. For RTM, a number of security changes were made. First config: To be able to connect to the management interface, your user must be added to the Performance Log Users group. After you make this change, you must log off and log back on as the token is only added to your login token when you log on. I forgot this and spent ages trying to work out why I couldn't connect. Second config: You need to reserve the URL that the...(read more)

• Make Apache encode or replace quotes instead of escaping them?

  - by mplungjan

  In the dcoumentation I read Format Notes For security reasons, starting with version 2.0.46, non-printable and other special characters in %r, %i and %o are escaped using \xhh sequences, where hh stands for the hexadecimal representation of the raw byte. Exceptions from this rule are " and \, which are escaped by prepending a backslash, and all whitespace characters, which are written in their C-style notation (\n, \t, etc). In versions prior to 2.0.46, no escaping was performed on these strings so you had to be quite careful when dealing with raw log files. This is a problem for Analog which is still the handiest analyser I use. I get .... "GET /somerequest?q=\"quoted string\"&someparm=bla" in the logfile and it is of course flagged as corrupt since Analog expects .... "GET /somerequest?q=%22quoted string%22&someparm=bla" or similar. I realise I can pre-process using something like perl -p -i.bak -e 's/\\"/%22/g' logfile But I'd rather not have to add this step to these files which are 50-90MB zipped per day Thanks for any pointers

• How does a government development shop transition to developing open source solutions?

  - by Rob Oesch

  Our shop has identified several reasons why releasing our software solutions to the open source community would be a good idea. However, there are several reasons from a business stand point why converting our shop to open source would be questioned. I need help from anyone out there who has gone through this transition, or is in the process. Specifically a government entity. About our shop: - We develop and support web and client applications for the local law enforcement community. - We are NOT a private company, rather a public sector entity Some questions that tend to come about when we have this discussion are: We're a government agency, so isn't our code already public? How do we protect ourselves from being 'hacked' if someone looks into our code? (There are obvious answers to this question like making sure you don't hard code passwords, etc. However, the discussion needs to consider an audience of executives who are very security conscience.)

• Advice on how to understand in general and in practice IT Infrastructure

  - by Luca

  My IT knowledge resides mainly in SW development. I have just some basic know how about networks. On the net I tried to get information and read books in order to better understand the overall IT infrastrcuture, but all the sources I found are too generic or, mainly, too detailed in just one aspect, making me lost. Could anyone suggest some books or web resources as good compromise in details? My goal would be able to understand the network issues and security threats when, for example, two remote system have to be setup and put in connection each other. Considering this scenario there are several aspects to consider: firewalls, intranet/internet interconnections, certificates for httpS, etc. The argument is quite wide, therefore I was looking for something that might help to start to understand this subject without going too deep in details (Computer Networks from A.Tanenbaum is a wonderful milestone, but way too specific for my scope).

• HP 530 Wireless problem. Bad communication with access point

  - by foxy

  I installed Ubuntu 11.10 on HP 530 and to make Wireless work installed STA driver from jockey (obviously proprietary) and, since it didn't work also installed their driver from HP website via ndiswrapper. After this (and a reboot) I see the WiFi indicator glowing, like it should be, and I am able to find local access points. But when I try to connect to mine personal one with WPA 2 security (with password) it hangs at authentification (I'm using wicd to manage wifi), and after a minute or so (I guess timeout of request happens) it says I have a wrong password (it is 100% correct). What might be the problem here? Yesterday I was able to connect to access point by changing type of encryption from passphrase to preshared key but didn't have internet access. Now, after reboot, I can't connect there again.

• dovecot main process terminated with status 89

  - by G. He

  I'm trying to configure dovecot/imap to run without SSL. I set ssl = no in 10-ssl.conf in /etc/dovecot/conf.d. However, with this setting, dovecot dies right away when it is started. I checked the log file and found the following: dovecot main process (4895) terminated with status 89 What does it mean? Is there a way for dovecot to run without ssl? The reason I do NOT want ssl is that my outlook complains the certificate cannot be verified. It is really annoying. And I only run the server on a very small lan and don't need that extra security.

• automount smb share customization

  - by Douda

  as a new linux user, used Ubuntu 12.10, I tried several tweaks with the SMB shares. I followed this tutorial to mount permanently 4 SMB shares from my local NAS. To resume, I : edit /etc/fstab added a line like : //servername/sharename /media/windowsshare cifs credentials=/home/ubuntuusername/.smbcredentials,iocharset=utf8,file_mode=0777,dir_mode=0777 0 0 created a credentials file for security reasons in my home folder (explained in the tutorial) ~/.smbcredentials It work perfectly, they are automounted on each reboot, but when I logon, I all the time get 4 file explorer open with each share. It is possible to avoid these file explorer window to be opened on every reboot ? I guess it's related to X or via a explicit deny or these graphical mount, but I don't have any clues on how to proceed Thank you for your time,
