• Issue with VMWare vSphere and NFS: re occurring apd state

  - by Bastian N.

  I am experiencing issues with VMWare vSphere 5.1 and NFS storage on 2 different setups, which result in an "All Path Down" state for the NFS shares. This first happened once or twice a day, but lately it occurs much more frequent, as specially when Acronis Backup jobs are running. Setup 1 (Production): 2 ESXi 5.1 hosts (Essentials Plus) + OpenFiler with NFS as storage Setup 2 (Lab): 1 ESXi 5.1 host + Ubuntu 12.04 LTS with NFS as storage Here is an example from the vmkernel.log: 2013-05-28T08:07:33.479Z cpu0:2054)StorageApdHandler: 248: APD Timer started for ident [987c2dd0-02658e1e] 2013-05-28T08:07:33.479Z cpu0:2054)StorageApdHandler: 395: Device or filesystem with identifier [987c2dd0-02658e1e] has entered the All Paths Down state. 2013-05-28T08:07:33.479Z cpu0:2054)StorageApdHandler: 846: APD Start for ident [987c2dd0-02658e1e]! 2013-05-28T08:07:37.485Z cpu0:2052)NFSLock: 610: Stop accessing fd 0x410007e4cf28 3 2013-05-28T08:07:37.485Z cpu0:2052)NFSLock: 610: Stop accessing fd 0x410007e4d0e8 3 2013-05-28T08:07:41.280Z cpu1:2049)StorageApdHandler: 277: APD Timer killed for ident [987c2dd0-02658e1e] 2013-05-28T08:07:41.280Z cpu1:2049)StorageApdHandler: 402: Device or filesystem with identifier [987c2dd0-02658e1e] has exited the All Paths Down state. 2013-05-28T08:07:41.281Z cpu1:2049)StorageApdHandler: 902: APD Exit for ident [987c2dd0-02658e1e]! 2013-05-28T08:07:52.300Z cpu1:3679)NFSLock: 570: Start accessing fd 0x410007e4d0e8 again 2013-05-28T08:07:52.300Z cpu1:3679)NFSLock: 570: Start accessing fd 0x410007e4cf28 again As long as the issue occurred once or twice a day it really wasn't a problem, but now this issue has impact on the VMs. The VMs get slow or even hang, resulting in a reset through vCenter in the production environment. I searched the web extensively and asked in forums, but till now nobody was able to help me. Based on blog posts and VMWare KB articles I tried the following NFS settings: Net.TcpipHeapSize = 32 Net.TcpipHeapMax = 128 NFS.HartbeatFrequency = 12 NFS.HartbeatMaxFailures = 10 NFS.HartbeatTimeout = 5 NFS.MaxQueueDepth = 64 Instead of NFS.MaxQueueDepth = 64 I already tried other settings like NFS.MaxQueueDepth = 32 or even NFS.MaxQueueDepth = 1. Unfortunately without any luck. It would be great if someone could help me on this issue. It is really annoying. Thanks in advance for all the help. [UPDATE] As I explained in the comment below, here is the network setup: On the production setup the NFS traffic is bound to a separate VLAN with ID 20. I am using a HP 1810 24 Port Switch. The OpenFiler system is connected to the VLAN with 4 Intel GbE NICs with dynamic LACP. The ESXis both have 4 Intel GbE NICs using 2 static LACP trunks containing 2 NICs each. One pair is connected to the regular LAN and the other one to the VLAN 20. And here is a screenshot of the vSwitch: Switch configuration: Port configuration: On the lab setup its a single Intel NIC on each side without VLAN, but with different IP subnet.

• logparser Message with error codes

  - by nsr81

  Hi All, Is there anyway to get complete error message using LogParser? When I run the following query: logparser -i:EVT -o:NAT "SELECT TimeGenerated,EventID,Message from System WHERE EventTypeName='Error event'" I get the following output: 2009-09-02 19:35:44 7000 The USB Mass Storage Driver service failed to start due to the following error: %%1058 The full "Message" in EventViewer is: Description: The USB Mass Storage Driver service failed to start due to the following error: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it. How can I obtain complete message using logparser?

• local cache for NAS or network folder

  - by HugoRune

  I am planning to build a network attached storage (NAS) server. Is there a way to cache frequently acccessed files from the remote storage automatically on the local PC? (I am not looking for a way to sync whole folders like rsync, but rather something that automatically and transparently caches the last accessed 50 gb of files.) Ideally I am searching for something that caches writes as well as reads, since only one pc will be accessing the server (and one day of lost changes if the local cache is damaged would be acceptable) I looked into windows offline files, but as far as I could tell this requires manual interaction to disconnect the server or go into offline mode in order to use the cache. The server would probably be running Linux or freeNAS, the pc runs Windows xp, but could be upgraded to 7 if required.

• How to Remove a VM From Hyper-V Without Deleting the Configuration File?

  - by Steven Murawski

  I'm in the process of moving a number of virtual machines that are homed on shared storage (a file share, though shared cluster disk would work as well) to a new VM host with access to the same shared storage. The new host is a different build version (moving from Windows Server 2012 Beta to Windows Server 2012 RC - though this same process could be used with migrations of Windows Server 2008/2008 R2 to Windows Server 2012 as well), so I cannot migrate the machine with inbox tooling. I need to remove the VM from management of the source Hyper-V host in order to import the VM to the new Hyper-V host. I want to retain the configuration file, so I can import the VM as it stands and not need to reconfigure it. The VHD files are rather large and they are staying on the same file share, so I'd rather not duplicate them during the move process.

• SDL doesn't detect Arrow Keys

  - by Scott

  I am working through the SDL tutorials over at http://lazyfoo.net/SDL_tutorials/index.php and I'm stuck on tutorial 8 where I'm working with key presses. I'm using the following code: //Our Main application loop while(!quit){ if(SDL_PollEvent(&curEvents)){ if(curEvents.type == SDL_QUIT){ quit = true; } //If a key was pressed if( curEvents.type == SDL_KEYDOWN ) { //Set the proper message surface switch( curEvents.key.keysym.sym ) { case SDLK_UP: message = upMessage; break; case SDLK_DOWN: message = downMessage; break; case SDLK_LEFT: message = leftMessage; break; case SDLK_RIGHT: message = rightMessage; break; default: message = TTF_RenderText_Solid(font, "Unknown Key", textColor); break; } } } if( message != NULL ) { //Apply the background to the screen applySurface( 0, 0, background, screen ); //Apply the message centered on the screen applySurface( ( SCREEN_WIDTH - message->w ) / 2, ( SCREEN_HEIGHT - message->h ) / 2, message, screen ); //Null the surface pointer message = NULL; } //Update the screen if( SDL_Flip( screen ) == -1 ) { return 1; } } Where works fine, the default case is reached, for everything BUT pressing the arrow keys. I was wondering if someone could spot what I'm doing wrong.

• UnicodeEncodeError when uploading files in Django admin

  - by Samuel Linde

  Note: I asked this question on StackOverflow, but I realize this might be a more proper place to ask this kind of question. I'm trying to upload a file called 'Testaråäö.txt' via the Django admin app. I'm running Django 1.3.1 with Gunicorn 0.13.4 and Nginx 0.7.6.7 on a Debian 6 server. Database is PostgreSQL 8.4.9. Other Unicode data is saved to the database with no problem, so I guess the problem must be with the filesystem somehow. I've set http { charset utf-8; } in my nginx.conf. LC_ALL and LANG is set to 'sv_SE.UTF-8'. Running 'locale' verifies this. I even tried setting LC_ALL and LANG in my nginx init script just to make sure locale is set properly. Here's the traceback: Traceback (most recent call last): File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/core/handlers/base.py", line 111, in get_response response = callback(request, *callback_args, **callback_kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/contrib/admin/options.py", line 307, in wrapper return self.admin_site.admin_view(view)(*args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/utils/decorators.py", line 93, in _wrapped_view response = view_func(request, *args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/views/decorators/cache.py", line 79, in _wrapped_view_func response = view_func(request, *args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/contrib/admin/sites.py", line 197, in inner return view(request, *args, **kwargs) File "/srv/django/letebo/app/cms/admin.py", line 81, in change_view return super(PageAdmin, self).change_view(request, obj_id) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/utils/decorators.py", line 28, in _wrapper return bound_func(*args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/utils/decorators.py", line 93, in _wrapped_view response = view_func(request, *args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/utils/decorators.py", line 24, in bound_func return func(self, *args2, **kwargs2) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/transaction.py", line 217, in inner res = func(*args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/contrib/admin/options.py", line 985, in change_view self.save_formset(request, form, formset, change=True) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/contrib/admin/options.py", line 677, in save_formset formset.save() File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/forms/models.py", line 482, in save return self.save_existing_objects(commit) + self.save_new_objects(commit) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/forms/models.py", line 613, in save_new_objects self.new_objects.append(self.save_new(form, commit=commit)) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/forms/models.py", line 717, in save_new obj.save() File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/models/base.py", line 460, in save self.save_base(using=using, force_insert=force_insert, force_update=force_update) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/models/base.py", line 504, in save_base self.save_base(cls=parent, origin=org, using=using) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/models/base.py", line 543, in save_base for f in meta.local_fields if not isinstance(f, AutoField)] File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/models/fields/files.py", line 255, in pre_save file.save(file.name, file, save=False) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/models/fields/files.py", line 92, in save self.name = self.storage.save(name, content) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/core/files/storage.py", line 48, in save name = self.get_available_name(name) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/core/files/storage.py", line 74, in get_available_name while self.exists(name): File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/core/files/storage.py", line 218, in exists return os.path.exists(self.path(name)) File "/srv/.virtualenvs/letebo/lib/python2.6/genericpath.py", line 18, in exists st = os.stat(path) UnicodeEncodeError: 'ascii' codec can't encode characters in position 52-54: ordinal not in range(128) I tried running Gunicorn with debugging turned on, and the file uploads without any problem at all.

• Problem installing Cardbus/PCMCIA drivers (USB 2.0 2-port)

  - by Carl

  I obtained the drivers from the manufacturer for my HT-Link NEC USB 2.0 2-port Cardbus card. When I plugged in the card before I got the drivers, 3 new entries showed up in the Device Manager - two "NEC PCI to USB Open Host Controller" and one "Standard Enhanced PCI to USB Host controller." With the card plugged in, I uninstalled those two drivers. I then removed the card. I copied the new drivers to c:\windows\system32\drivers and the .inf file to c:\windows\inf. I also copied the drivers & inf to a new directory called c:\windows\drivers\ousb2. I reinserted the card. Windows automatically installed the same drivers as before. I selected 'update driver' on the "NEC PCI to USB..." entry and didn't see any other options. I then selected 'have disk' and pointed to c:\windows\drivers\ousb2 and got a message "The specified location does not contain information about your hardware." I then selected 'update driver' on the "Standard Enhanced PCI to USB...," and manually selected "USB 2.0 Enhanced Host Controller" (OWC 4/15/2003 2.1.3.1). Windows then automatically found a USB root hub, and I manually selected "USB 2.0 Root Hub Device" (OWC 4/15/2003 2.1.3.1). Now there are two sections in the Device Manager titled "Universal Serial Bus controllers." I plugged in my external USB hard disk adapter, and "USB Mass Storage Device" was added to the first set. Here's how it looks (w/drivers from the properties): [Universal Serial Bus controllers] Intel(R) 82801DB/DBM USB 2.0 Enhanced Host Controller - 24CD (6/1/2002 5.1.2600.0) Intel(R) 82801DB/DBM USB Universal Host Controller - 24C2 (7/1/2001 5.1.2600.5512) Intel(R) 82801DB/DBM USB Universal Host Controller - 24C4 (7/1/2001 5.1.2600.5512) Intel(R) 82801DB/DBM USB Universal Host Controller - 24C7 (7/1/2001 5.1.2600.5512) NEC PCI to USB Open Host Controller (7/1/2001 5.1.2600.5512) NEC PCI to USB Open Host Controller (7/1/2001 5.1.2600.5512) USB Mass Storage Device USB Root Hub (7/1/2001 5.1.2600.5512) (5 more USB Root Hubs - same driver) [Universal Serial Bus controllers] USB 2.0 Enhanced Host Controller (OWC 4/15/2003 2.1.3.1) USB 2.0 Root Hub Device (OWC 4/15/2003 2.1.3.1) When I unplug the card the two "NEC PCI to USB..." entries in the first set disappear, and the whole second set disappears. (I unplugged the hard disk adapter first...) The hard disk adapter still doesn't work in that Cardbus card with the new drivers. I don't think the above looks right - a second set of USB controllers listed in the Device Manager, and the NEC entries still in the first set, and the the USB mass storage device still in the first set. Any help appreciated. (Windows XP PRO SP3 w/all current updates.)

• Base class -> Derived class and vice-versa conversions in C++

  Hi! I have the following example code: #include <iostream> #include <string> using namespace std; class Event { public: string type; string source; }; class KeyEvent : public Event { public: string key; string modifier; }; class MouseEvent : public Event { public: string button; int x; int y; }; void handleEvent(KeyEvent e) { if(e.key == "ENTER") cout << "Hello world!

• How to connect to a queue manager with ssl enabled server connection channel when authentication is

  - by Dr. Xray

  I am trying to write a java application connecting to server connection channel with SSL enabled. So far, I have been successfully connected to the channel by setting authentication to 'optional'. However, when I set it to be 'required', the connection fails. Here is what I did: Create key db for queue manager and keystore for the java client user. Create key/self-signed certificates for the queue manager and the client user, with names prefixed ibmwebspheremq. Export, exchange and import certificates for the queue manager and the client. (I did answered 'yes' when being asked whether I trust the queue manager cert). The location and password to the truststore and keystore are set to point to the same keystore at the client side, where the orgininal created client user key and the imported queue manager key are. With other settings being the same, if I switch back to 'optional' authentication, the connection works. I think there is something I understand incorrectly about this ssl authenticaion but cannot figure out what. Could someone kindly help me?

• development server?

  - by ajsie

  for a project there will be me and one more programmer to develop a web service. i wonder how the development environment should be like. cause we need central storage (documents, pictures, business materials etc), file version handling, lamp (testing the web service) etc. i have never set up an environment for this before and want to have suggestions from experienced people which tools to use for effective collaboration. what crossed my mind: seperate applications: - google wave (for communication forth and back, setting up guide lines, other information) - team viewer (desktop sharing) - skype (calling) vps (ubuntu server): - svn (version tracking) - ftp (central storage) - lamp (testing the web service) - ssh (managing the vps) is this an appropriate programming environment? and regarding the vps, is it best practice to use ONE vps for all tasks listed up there? all suggestions and feedbacks are welcome!

But when using this code I regularly get some phantom key-code being pressed. The application I'm using this on is obviously world of warcraft, and I have checked that all keybinds are standard keybinds. However randomly it seems I get either an up arrow, or a w pressed, which moves my character forward whenever this code executes (F12 is bound to a macro, unbound from any movement. If I press f12 with a hardware event, it does not exhibit this behavior. What in the world could be going on here?

• "no block given" errors with cache_money

  i've inherited a site that in production is generating dozens of "no block given" exceptions every 5 minutes. the top of the stack trace is: vendor/gems/nkallen-cache-money-0.2.5/lib/cash/accessor.rb:42:in `add' vendor/gems/nkallen-cache-money-0.2.5/lib/cash/accessor.rb:33:in `get' vendor/gems/nkallen-cache-money-0.2.5/lib/cash/accessor.rb:22:in `call' vendor/gems/nkallen-cache-money-0.2.5/lib/cash/accessor.rb:22:in `fetch' vendor/gems/nkallen-cache-money-0.2.5/lib/cash/accessor.rb:31:in `get' so it appears that the problem is in the cache money plugin. has anyone experienced something similar? i've cut and pasted the relevant code below -- anyone more familiar with blocks able to discern any obvious problems? 11 def fetch(keys, options = {}, &block) 12 case keys 13 when Array 14 keys = keys.collect { |key| cache_key(key) } 15 hits = repository.get_multi(keys) 16 if (missed_keys = keys - hits.keys).any? 17 missed_values = block.call(missed_keys) 18 hits.merge!(missed_keys.zip(Array(missed_values)).to_hash) 19 end 20 hits 21 else 22 repository.get(cache_key(keys), options[:raw]) || (block ? block.call : nil) 23 end 24 end 25 26 def get(keys, options = {}, &block) 27 case keys 28 when Array 29 fetch(keys, options, &block) 30 else 31 fetch(keys, options) do 32 if block_given? 33 add(keys, result = yield(keys), options) 34 result 35 end 36 end 37 end 38 end 39 40 def add(key, value, options = {}) 41 if repository.add(cache_key(key), value, options[:ttl] || 0, options[:raw]) == "NOT_STORED\r\n" 42 yield 43 end 44 end

• sudo/su command for Red Hat Server 5.4

  - by rednaxela

  Without going into too much detail, I need to execute one linux command on redhat with root user access. Red Hat Server 5.4 does not recognise the sudo command. The command su can be used to switch to the root user on redhat, but su cannot be done in one line. For example the command: su ; cd opt/storage/RootAccessFolder will not work because this only switches you to root, then executes the cd command once you have logged out from the root user. I guess what i'm looking for is like a.. sudo cd opt/storage/RootAccessFolder but I say again, sudo doesn't work. Any ideas?

• How can I tell if ZFS (zfs-fuse) dedup/compression is applied to a particular file?

  I have a zfs formatted partition using zfs-fuse for linux (Ubuntu). I had used it for a while, and then enabled dedup and compression on it (zfs set compression=on/dedup=on). Now I think I have some files that are dedup'ed and compressed, and file that are not yet. It was OK, but sometimes I was confused. Let's see, following command would consume almost 4GB of my zfs storage: cp oldfile.4GB newfile.4GB .. and this would consume almost zero: cp newfile.4GB newfile.4GB.2 This is because the old file is not yet compressed, so dedup not happened, I think. My idea is -- if I can find old files that are not yet dedup/compressed, I can perform batch copy/rename/remove them to eliminate duplicity and redundancy. But how I can check that? I know I can re-copy whole contents of my storage should work (even better with checking the time stamp of each file), but I'd be happier if I have zfsstat-like tool that shows some file properties.

• Django: Odd mark_safe behaviour?

  - by Mark

  I wrote this little function for writing out HTML tags: def html_tag(tag, content=None, close=True, attrs={}): lst = ['<',tag] for key, val in attrs.iteritems(): lst.append(' %s="%s"' % (key, escape_html(val))) if close: if content is None: lst.append(' />') else: lst.extend(['>', content, '</', tag, '>']) else: lst.append('>') return mark_safe(''.join(lst)) Which worked great, but then I read this article on efficient string concatenation (I know it doesn't really matter for this, but I wanted consistency) and decided to update my script: def html_tag(tag, body=None, close=True, attrs={}): s = StringIO() s.write('<%s'%tag) for key, val in attrs.iteritems(): s.write(' %s="%s"' % (key, escape_html(val))) if close: if body is None: s.write(' />') else: s.write('>%s</%s>' % (body, tag)) else: s.write('>') return mark_safe(s.getvalue()) But now my HTML get escaped when I try to render it from my template. Everything else is exactly the same. It works properly if I replace the last line with return mark_safe(unicode(s.getvalue())). I checked the return type of s.getvalue(). It should be a str, just like the first function, so why is this failing?? Also fails with SafeString(s.getvalue()) but succeeds with SafeUnicode(s.getvalue()). I'd also like to point out that I used return mark_safe(s.getvalue()) in a different function with no odd behavior. The "call stack" looks like this: class Input(Widget): def render(self): return html_tag('input', attrs={'type':self.itype, 'id':self.id, 'name':self.name, 'value':self.value, 'class':self.itype}) class Field: def __unicode__(self): return mark_safe(self.widget.render()) And then {{myfield}} is in the template. So it does get mark_safed'd twice, which I thought might have been the problem, but I tried removing that too..... I really have no idea what's causing this, but it's not too hard to work around, so I guess I won't fret about it.

• Email Servers that Abstracts Mailbox Concepts [on hold]

  - by David

  Lately I've been really interested in doing some very unique things with email most of which rely on a SMTP and POP or IMAP server that gives the administrator an API to create arbitrary methods for email storage, notifications, or delivery. What I'm looking for would be analogous to mod_php and apache where apache handles the delivery protocol and php handles the content creation and storage. I've considered making my own, as those three protocols are quite simple, but I'm always nervous about putting my code public facing especially when it's at that low of a level. So are there any email servers that allow for this much arbitrary control over email delivery, fetching, and receiving.

• selective backup script in bash

  - by Sake

  Hi, I've been using this simple command (that's all I can do :) to backup the whole tree from my user data in NAS server for a year. cp -r /STORAGE /BACKUP-STORAGE/YYYY-MM-DD Unfortunately, after a year of service. My user start filling the spaces with lot of photo and cliparts (jpg, gif, bmp) And that start to make my backup process get much slower. The space is also a big issue. Now I no longer have enough space for a week-long daily backup set. I think I want to change from backup everything to backup only non-image data. How can I exclude jpg, gif, and bmp from the backup ? It's quite easy with DOS XCOPY command, but I really have no idea how to do that in bash. Thanks

• Is android's motion event handling accurate??

  - by Peterdk

  Bug I have a weird bug in my piano app. Sometimes keys (and thus notes) hang. I did a lot of debugging and narrowed it down to what looks like androids inaccuracy of motion event handling: DEBUG/(2091): ACTION_DOWN A4 DEBUG/(2091): KeyDown: A4 DEBUG/(2091): ACTION_MOVE A4 => A4 DEBUG/(2091): ACTION_MOVE ignoring DEBUG/(2091): ACTION_MOVE A4 => A4 DEBUG/(2091): ACTION_MOVE ignoring DEBUG/(2091): ACTION_MOVE A4 => A4 DEBUG/(2091): ACTION_MOVE ignoring DEBUG/(2091): ACTION_UP B4 //HOW CAN THIS BE???? DEBUG/(2091): KeyUp: B4 DEBUG/(2091): Stream is null, can't stop DEBUG/(2091): Hanging Note: A4 X=240-287 EventX=292 Y=117-200 EventY=164 DEBUG/(2091): KeyUp Note: B4 X=288-335 EventX=292 Y=117-200 EventY=164 Clearly it can be seen here that out of nowhere I suddenly have an ACTION_UP for another note. Shouldn't I definitely get a ACTION_MOVE first? As shown in the end of the log, it's definitely not an error in region detection, since the ACTION_UP event is clearly in the B4 region. Logging Implementation details Every onTouchEvent() call is logged, so the log is accurate. The relevant pseudo-code for the ACTION_MOVE logging is: Key oldKey = Key.get(event.getHistoricalX(), event.getHistoricalY()); Key newKey = Key.get(event.getX(), event.getY()); Question Is this normal behaviour for Android (the jumping in coordinates)? Am I missing something?

• Automate the signature of the update.rdf manifest for my firefox extension

  - by streetpc

  Hello, I'm developing a firefox extension and I'd like to provide automatic update to my beta-testers (who are not tech-savvy). Unfortunately, the update server doesn't provide HTTPS. According to the Extension Developer Guide on signing updates, I have to sign my update.rdf and provide an encoded public key in the install.rdf. There is the McCoy tool to do all of this, but it is an interactive GUI tool and I'd like to automate the extension packaging using an Ant script (as this is part of a much bigger process). I can't find a more precise description of what's happening to sign the update.rdf manifest than below, and McCoy source is an awful lot of javascript. The doc says: The add-on author creates a public/private RSA cryptographic key pair. The public part of the key is DER encoded and then base 64 encoded and added to the add-on's install.rdf as an updateKey entry. (...) Roughly speaking the update information is converted to a string, then hashed using a sha512 hashing algorithm and this hash is signed using the private key. The resultant data is DER encoded then base 64 encoded for inclusion in the update.rdf as an signature entry. I don't know well about DER encoding, but it seems like it needs some parameters. So would anyone know either the full algortihm to sign the update.rdf and install.rdf using a predefined keypair, or a scriptable alternative to McCoy whether a command-line tool like asn1coding will suffise a good/simple developer tutorial on DER encoding

• Correctly use dependency injection

  - by Rune

  Me and two other colleagues are trying to understand how to best design a program. For example, I have an interface ISoda and multiple classes that implement that interface like Coke, Pepsi, DrPepper, etc.... My colleague is saying that it's best to put these items into a database like a key/value pair. For example: Key | Name -------------------------------------- Coke | my.namespace.Coke, MyAssembly Pepsi | my.namespace.Pepsi, MyAssembly DrPepper | my.namespace.DrPepper, MyAssembly ... then have XML configuration files that map the input to the correct key, query the database for the key, then create the object. I don't have any specific reasons, but I just feel that this is a bad design, but I don't know what to say or how to correctly argue against it. My second colleague is suggesting that we micro-manage each of these classes. So basically the input would go through a switch statement, something similiar to this: ISoda soda; switch (input) { case "Coke": soda = new Coke(); break; case "Pepsi": soda = new Pepsi(); break; case "DrPepper": soda = new DrPepper(); break; } This seems a little better to me, but I still think there is a better way to do it. I've been reading up on IoC containers the last few days and it seems like a good solution. However, I'm still very new to dependency injection and IoC containers, so I don't know how to correctly argue for it. Or maybe I'm the wrong one and there's a better way to do it? If so, can someone suggest a better method? What kind of arguments can I bring to the table to convince my colleagues to try another method? What are the pros/cons? Why should we do it one way? Unfortunately, my colleagues are very resistant to change so I'm trying to figure out how I can convince them.

• Suppress task switch keys (winkey, alt-tab, alt-esc, ctrl-esc) using low-level keyboard hook

  - by matt

  I'm trying to suppress task switch keys (such as winkey, alt-tab, alt-esc, ctrl-esc, etc.) by using a low-level keyboard hook. I'm using the following LowLevelKeyboardProc callback: IntPtr HookCallback(int nCode, IntPtr wParam, ref KBDLLHOOKSTRUCT lParam) { if (nCode >= 0) { bool suppress = false; // Suppress left and right windows keys. if (lParam.Key == VK_LWIN || lParam.Key == VK_RWIN) suppress = true; // Suppress alt-tab. if (lParam.Key == VK_TAB && HasAltModifier(lParam.Flags)) suppress = true; // Suppress alt-escape. if (lParam.Key == VK_ESCAPE && HasAltModifier(lParam.Flags)) suppress = true; // Suppress ctrl-escape. /* How do I hook CTRL-ESCAPE ? */ // Suppress keys by returning 1. if (suppress) return new IntPtr(1); } return CallNextHookEx(HookID, nCode, wParam, ref lParam); } bool HasAltModifier(int flags) { return (flags & 0x20) == 0x20; } However, I'm at a loss as to how to suppress the CTRL-ESC combination. Any suggestions? Thanks.

• jQuery Ajax / .each callback, next 'each' firing before ajax completed

  - by StuR

  Hi the below Javascript is called when I submit a form. It first splits a bunch of url's from a text area, it then: 1) Adds lines to a table for each url, and in the last column (the 'status' column) it says "Not Started". 2) Again it loops through each url, first off it makes an ajax call to check on the status (status.php) which will return a percentage from 0 - 100. 3) In the same loop it kicks off the actual process via ajax (process.php), when the process has completed (bearing in the mind the continuous status updates), it will then say "Completed" in the status column and exit the auto_refresh. 4) It should then go to the next 'each' and do the same for the next url. function formSubmit(){ var lines = $('#urls').val().split('\n'); $.each(lines, function(key, value) { $('#dlTable tr:last').after('<tr><td>'+value+'</td><td>Not Started</td></tr>'); }); $.each(lines, function(key, value) { var auto_refresh = setInterval( function () { $.ajax({ url: 'status.php', success: function(data) { $('#dlTable').find("tr").eq(key+1).children().last().replaceWith("<td>"+data+"</td>"); } }); }, 1000); $.ajax({ url: 'process.php?id='+value, success: function(msg) { clearInterval(auto_refresh); $('#dlTable').find("tr").eq(key+1).children().last().replaceWith("<td>completed rip</td>"); } }); }); }

• (simple) linux HA with vmware vsphere?

  - by derhelge

  I hope my upcoming question is specific enough, and you are able and willing to support :-) We have several openSUSE VMs in an ESX-Cluster (three ESX-Servers) with an attached iSCSI-SAN. All of those Linux VMs are "single point of failure"-configured, which means in the case of a Web-Server: LAMP, storage, etc. everything on this machine. This was very simple and in case of a failure (in the last years: kernel panics or apache crashes) a simple reboot triggered by a script did it. But the problem is: How to upgrade/maintain the w(eb-)application or the underlying OS without downtime? This wasn't really managable and i did this in the early morning ;) How can i achieve a "simple" High-Availability Cluster now? I thought of: DRBD with heartbeat with 2 VMs. And for the storage a RDM (raw device mapped) LUN and change the read-write-permissions for both VMs. Is this a good idea? Anyone has a better solution?
