• Development environment for embedded system

  - by Howard Lee Harkness

  I need to develop software in C/C++ for an embedded system. I have Debian 6 running off of a USB hard drive. I would like to be able to generate a stripped-down kernel with modules, and install them either on a CF card or a USB 'thumb' drive. I succeeded in building a Linux 3.6 kernel and running it in Debian off of the USB hard drive, but I am having trouble figuring out how to install it on the thumb drive. I would like a build cycle that looks like this: 1) Build module or kernel with desired software 2) Install it on thumb drive 3) Boot and test I would like to use the same system for both development and testing, if that is feasible. I am looking for resources and tutorials that would help me understand how to do this.

• How to know if my nginx is in good health?

  - by Howard

  I am running a nginx on EC2 (m1.small) for SSL termination. I am using 2 workers on Ubuntu, with latest nginx (stable), the network throughput is around 2Mbps and system load average is around 2 to 3. I am wondering if this system is in good health for now, e.g. what is the queue length (I know nginx can handle a lot of concurrent request, but I mean before the request is being served, how many of them need to wait before being served) what is the average queue time for a given request to be served. I want to know because if my nginx is cpu bounded (e.g. due to SSL), I will need to upgrade to a faster instance. My current nginx status Active connections: 4076 server accepts handled requests 90664283 90664283 104117012 Reading: 525 Writing: 81 Waiting: 3470

• Double try_files to solve the nginx's "No input file specified" issue

  - by Howard

  I am following the nginx's wiki (http://wiki.nginx.org/WordPress) to setup my wordpress location / { try_files $uri $uri/ /index.php?$args; } By using the above lines, when a static file which is not found it will redirect to index.php of wordpress, that is okay but.. Problem: When I request an non-existence php script, e.g. http://www.example.com/foo.php, nginx will give me No input file specified I want nginx to return 404 instead of the above message, so in the main fcgi config, I add the 2nd try_files location ~ \.php$ { try_files $uri =404; fastcgi_split_path_info ^(.+\.php)(/.+)$; include /etc/nginx/fastcgi_params; ... } And this worked, but I am looking if there are any better way to handle it?

• Windows 7 - XP Mode - Apache

  - by Howard

  I've setup Virtual PC and XP Mode on my Windows 7 Pro. Using Apache 2.0.52 I have no problems having my website up and running on the Windows 7 machine. But Under VPC/XP Mode the best I can do is Localhost mode. What do I need to do to enable http connections? I need the XP Mode as besides the website I also run a Web BBS and a Dos based (via telnet) BBS. Some of the apps in the Dos BBS just won't work under 64 bit, no matter what setting (capability) are used. Thanks in advance...

• How to get the MongoDB' current working set size

  - by Howard

  From the doc , it said "For best performance, the majority of your active set should fit in RAM." So for example, my db.stats() give me { "db" : "mydb", "collections" : 16, "objects" : 21452, "avgObjSize" : 768.0516501957859, "dataSize" : 16476244, "storageSize" : 25385984, "numExtents" : 43, "indexes" : 70, "indexSize" : 15450112, "fileSize" : 469762048, "ok" : 1 } Which value is the working set size?

• Programming concepts taken from the arts and humanities

  - by Joey Adams

  After reading Paul Graham's essay Hackers and Painters and Joel Spolsky's Advice for Computer Science College Students, I think I've finally gotten it through my thick skull that I should not be loath to work hard in academic courses that aren't "programming" or "computer science" courses. To quote the former: I've found that the best sources of ideas are not the other fields that have the word "computer" in their names, but the other fields inhabited by makers. Painting has been a much richer source of ideas than the theory of computation. — Paul Graham, "Hackers and Painters" There are certainly other, much stronger reasons to work hard in the "boring" classes. However, it'd also be neat to know that these classes may someday inspire me in programming. My question is: what are some specific examples where ideas from literature, art, humanities, philosophy, and other fields made their way into programming? In particular, ideas that weren't obviously applied the way they were meant to (like most math and domain-specific knowledge), but instead gave utterance or inspiration to a program's design and choice of names. Good examples: The term endian comes from Gulliver's Travels by Tom Swift (see here), where it refers to the trivial matter of which side people crack open their eggs. The terms journal and transaction refer to nearly identical concepts in both filesystem design and double-entry bookkeeping (financial accounting). mkfs.ext2 even says: Writing superblocks and filesystem accounting information: done Off-topic: Learning to write English well is important, as it enables a programmer to document and evangelize his/her software, as well as appear competent to other programmers online. Trigonometry is used in 2D and 3D games to implement rotation and direction aspects. Knowing finance will come in handy if you want to write an accounting package. Knowing XYZ will come in handy if you want to write an XYZ package. Arguably on-topic: The Monad class in Haskell is based on a concept by the same name from category theory. Actually, Monads in Haskell are monads in the category of Haskell types and functions. Whatever that means...

• What free space thresholds/limits are advisable for 640 GB and 2 TB hard disk drives with ZEVO ZFS on OS X?

  - by Graham Perrin

  Assuming that free space advice for ZEVO will not differ from advice for other modern implementations of ZFS … Question Please, what percentages or amounts of free space are advisable for hard disk drives of the following sizes? 640 GB 2 TB Thoughts A standard answer for modern implementations of ZFS might be "no more than 96 percent full". However if apply that to (say) a single-disk 640 GB dataset where some of the files most commonly used (by VirtualBox) are larger than 15 GB each, then I guess that blocks for those files will become sub optimally spread across the platters with around 26 GB free. I read that in most cases, fragmentation and defragmentation should not be a concern with ZFS. Sill, I like the mental picture of most fragments of a large .vdi in reasonably close proximity to each other. (Do features of ZFS make that wish for proximity too old-fashioned?) Side note: there might arise the question of how to optimise performance after a threshold is 'broken'. If it arises, I'll keep it separate. Background On a 640 GB StoreJet Transcend (product ID 0x2329) in the past I probably went beyond an advisable threshold. Currently the largest file is around 17 GB –  – and I doubt that any .vdi or other file on this disk will grow beyond 40 GB. (Ignore the purple masses, those are bundles of 8 MB band files.) Without HFS Plus: the thresholds of twenty, ten and five percent that I associate with Mobile Time Machine file system need not apply. I currently use ZEVO Community Edition 1.1.1 with Mountain Lion, OS X 10.8.2, but I'd like answers to be not too version-specific. References, chronological order ZFS Block Allocation (Jeff Bonwick's Blog) (2006-11-04) Space Maps (Jeff Bonwick's Blog) (2007-09-13) Doubling Exchange Performance (Bizarre ! Vous avez dit Bizarre ?) (2010-03-11) … So to solve this problem, what went in 2010/Q1 software release is multifold. The most important thing is: we increased the threshold at which we switched from 'first fit' (go fast) to 'best fit' (pack tight) from 70% full to 96% full. With TB drives, each slab is at least 5GB and 4% is still 200MB plenty of space and no need to do anything radical before that. This gave us the biggest bang. Second, instead of trying to reuse the same primary slabs until it failed an allocation we decided to stop giving the primary slab this preferential threatment as soon as the biggest allocation that could be satisfied by a slab was down to 128K (metaslab_df_alloc_threshold). At that point we were ready to switch to another slab that had more free space. We also decided to reduce the SMO bonus. Before, a slab that was 50% empty was preferred over slabs that had never been used. In order to foster more write aggregation, we reduced the threshold to 33% empty. This means that a random write workload now spread to more slabs where each one will have larger amount of free space leading to more write aggregation. Finally we also saw that slab loading was contributing to lower performance and implemented a slab prefetch mechanism to reduce down time associated with that operation. The conjunction of all these changes lead to 50% improved OLTP and 70% reduced variability from run to run … OLTP Improvements in Sun Storage 7000 2010.Q1 (Performance Profiles) (2010-03-11) Alasdair on Everything » ZFS runs really slowly when free disk usage goes above 80% (2010-07-18) where commentary includes: … OpenSolaris has changed this in onnv revision 11146 … [CFT] Improved ZFS metaslab code (faster write speed) (2010-08-22)

• Using windowmaker with quartz-wm in proxy mode on Snow Leopard

  - by Graham Lee

  I can modify my .xinitrc file to exec /opt/local/bin/wmaker, and get WindowMaker 0.90.2 as my window manager in X11.app. I'd like to use quartz-wm not as a window manager, but to provide the pasteboard integration with Aqua using the --only-proxy flag (see the man page). If I add the following line to .xinitrc: exec /usr/bin/quartz-wm --only-proxy & then WindowMaker never starts, complaining that there's already a window manager running. Is it possible to get the two to play nicely together, or is proxy feature part of the Xquartz server now? It seems that the Xquartz manpage has a number of pasteboard-to-clipboard synchronisation settings, but it's not clear whether quartz-wm needs to be running for those to work.

• SSH: How to change value in config file in one command

  - by Brian Graham

  How can I change the value of, let's say, PasswordAuthentication in /etc/ssh/sshd_config in commands? As well, remove a # in front of the "key" I wish to value. These don't all have to be in one command. I setup quite a few servers, and remembering where everything is gets exhausting, so I want to get a series of commands I can copy paste and it does the work for me for future reference. Sample values: PermitRootLogin no ChallengeResponseAuthentication no PasswordAuthentication no UsePAM no UseDNS no

• How to check that all ZFS snapshots within a pool are without holds before destroying that pool

  - by Graham Perrin

  Question Already I can check each snapshot of a filesystem individually, manually. I would prefer to check all at once (all with a single command or script). Please: can that be done with a script? Background From the man page for zfs(8): zfs holds [-H] [-r] snapshot… … -r Specifies that a hold with the given tag is applied recursively to the snapshots of all descendent file systems.

• How can I create a custom OpenOffice / LibreOffice Writer table AutoFormat scheme?

  - by Merlyn Morgan-Graham

  None of the basic table AutoFormat schemes in LibreOffice Writer have both an alternation style defined and no sum column/row style defined. If they have alternation, they always seem to have sums. Because of this I'd like to define my own table scheme. What is the easiest way to accomplish this? A WYSIWYG isn't totally necessary. I am not scared of editing simple XML files as long as I have examples to work from, and if I don't have to edit base install files. If I can place them in a custom area or my user profile directory then that would be best. If there is a way to get the GUI Add functionality to properly recognize an alternation then that would also be helpful.

• Is StoreJet Transcend (0x2329) an Advanced Format drive?

  - by Graham Perrin

  I use a 640 GB StoreJet Transcend (0x2329) with ZEVO Community Edition 1.1.1 on OS X 10.8.2. Question Is this drive Advanced Format?

Mine is probably 25M2 (TS640GSJ25M2): Unless I'm missing something, nothing currently in the Transcend support area tells me whether the drive is Advanced Format.

• GitLab post-receive hook not firing

  - by Ben Graham

  Apologies if this isn't the right stackexchange. I have a GitLab install. It was installed over the top of a gitolite install that was only a few days old, and I assume this non-standard setup is at the root of my problem, but I cannot pin it down. The problem is straightforward: post-receive hooks are not fired. This prevents 'project activity' appearing in GitLab. The problem looks like: $ git push #... error: cannot run hooks/post-receive: No such file or directory Hook Exists The post-receive hook/symlink exists and is executable: -rwxr-xr-x 1 git git 470 Oct 3 2012 .gitolite/hooks/common/post-receive lrwxrwxrwx 1 git git 45 Oct 3 2012 repositories/project.git/hooks/post-receive -> /home/git/.gitolite/hooks/common/post-receive It's Executable By GitLab The gitlab user can execute the script (I have removed the /dev/null redirect and fed in blank input to get an 'OK' as output): sudo su - gitlab -c /home/git/.gitolite/hooks/common/post-receive OK GitLab Can Find It GitLab is looking for hooks in the correct location: $ grep hooks /srv/gitlab/gitlab/config/gitlab.yml hooks_path: /home/git/.gitolite/hooks/ and $ bundle exec rake gitlab:app:status RAILS_ENV=production # ... /home/git/.gitolite/hooks/common/post-receive exists? ............YES Environment The env -i line in the hook is commonly cited as an issue.

• Set a custom start date for week numbers

This network currently has a server (Windows Server 2008R2) running RRAS that establishes connectivity to the internet using a demand-dial PPPoE connection and handles the NAT. It also hosts a DNS server and DHCP. My ISP does not support IPv6, but I have a static IPv4 address. I've read about 6to4 and signed up at tunnelbroker.net, but quickly felt out of my depth. How do I configure my network to use it, and how I should configure my DHCP server with regards to IPv6 addresses?

• Can I configure mod_proxy to use different parameters based on HTTP Method?

  - by Graham Lea

  I'm using mod_proxy as a failover proxy with two balance members. While mod_proxy marks dead nodes as dead, it still routes one request per minute to each dead node and, if it's still dead, will either return 503 to the client (if maxattempts=0) or retry on another node (if it's 0). The backends are serving a REST web service. Currently I have set maxattempts=0 because I don't want to retry POSTs and DELETEs. This means that when one node is dead, each minute a random client will receive a 503. Unfortunately, most of our clients are interpreting codes like 503 as "everything is dead" rather than "that didnt work but please try that again". In order to program some kind of automatic retry for safe requests at the proxy layer, I'd like to configure mod_proxy to use maxattempts=1 for GET and HEAD requests and maxattempts=0 for all other HTTP Methods. Is this possible? (And how? :)

• Plug and Go NAS Storage

  - by graham.reeds

  My wife and I are separating. One of the things we need to extricate is the media we have accumulated over the years. So I am looking for a NAS solution that is a) relatively low-cost, b) reliable and c) easy for a non-geek to use (I don't want to be tech support). All it needs to do is hold our iTunes library, photos, course work and maybe some movies and TV shows that I currently have. She will be connecting via her Netbook. I have seen this thread but the reviews on Amazon aren't particularly favourable. Due to the need for simplicity, WHS and FreeNAS are none-starters. I need redundancy as if a single drive system was to die then she would lose her course work and photos. Is the ReadyNAS the only real solution out there?
