  • C#/.NET Little Wonders: ConcurrentBag and BlockingCollection

    - by James Michael Hare
    In the first week of concurrent collections, began with a general introduction and discussed the ConcurrentStack<T> and ConcurrentQueue<T>.  The last post discussed the ConcurrentDictionary<T> .  Finally this week, we shall close with a discussion of the ConcurrentBag<T> and BlockingCollection<T>. For more of the "Little Wonders" posts, see C#/.NET Little Wonders: A Redux. Recap As you'll recall from the previous posts, the original collections were object-based containers that accomplished synchronization through a Synchronized member.  With the advent of .NET 2.0, the original collections were succeeded by the generic collections which are fully type-safe, but eschew automatic synchronization.  With .NET 4.0, a new breed of collections was born in the System.Collections.Concurrent namespace.  Of these, the final concurrent collection we will examine is the ConcurrentBag and a very useful wrapper class called the BlockingCollection. For some excellent information on the performance of the concurrent collections and how they perform compared to a traditional brute-force locking strategy, see this informative whitepaper by the Microsoft Parallel Computing Platform team here. ConcurrentBag<T> – Thread-safe unordered collection. Unlike the other concurrent collections, the ConcurrentBag<T> has no non-concurrent counterpart in the .NET collections libraries.  Items can be added and removed from a bag just like any other collection, but unlike the other collections, the items are not maintained in any order.  This makes the bag handy for those cases when all you care about is that the data be consumed eventually, without regard for order of consumption or even fairness – that is, it’s possible new items could be consumed before older items given the right circumstances for a period of time. So why would you ever want a container that can be unfair?  Well, to look at it another way, you can use a ConcurrentQueue and get the fairness, but it comes at a cost in that the ordering rules and synchronization required to maintain that ordering can affect scalability a bit.  Thus sometimes the bag is great when you want the fastest way to get the next item to process, and don’t care what item it is or how long its been waiting. The way that the ConcurrentBag works is to take advantage of the new ThreadLocal<T> type (new in System.Threading for .NET 4.0) so that each thread using the bag has a list local to just that thread.  This means that adding or removing to a thread-local list requires very low synchronization.  The problem comes in where a thread goes to consume an item but it’s local list is empty.  In this case the bag performs “work-stealing” where it will rob an item from another thread that has items in its list.  This requires a higher level of synchronization which adds a bit of overhead to the take operation. So, as you can imagine, this makes the ConcurrentBag good for situations where each thread both produces and consumes items from the bag, but it would be less-than-idea in situations where some threads are dedicated producers and the other threads are dedicated consumers because the work-stealing synchronization would outweigh the thread-local optimization for a thread taking its own items. Like the other concurrent collections, there are some curiosities to keep in mind: IsEmpty(), Count, ToArray(), and GetEnumerator() lock collection Each of these needs to take a snapshot of whole bag to determine if empty, thus they tend to be more expensive and cause Add() and Take() operations to block. ToArray() and GetEnumerator() are static snapshots Because it is based on a snapshot, will not show subsequent updates after snapshot. Add() is lightweight Since adding to the thread-local list, there is very little overhead on Add. TryTake() is lightweight if items in thread-local list As long as items are in the thread-local list, TryTake() is very lightweight, much more so than ConcurrentStack() and ConcurrentQueue(), however if the local thread list is empty, it must steal work from another thread, which is more expensive. Remember, a bag is not ideal for all situations, it is mainly ideal for situations where a process consumes an item and either decomposes it into more items to be processed, or handles the item partially and places it back to be processed again until some point when it will complete.  The main point is that the bag works best when each thread both takes and adds items. For example, we could create a totally contrived example where perhaps we want to see the largest power of a number before it crosses a certain threshold.  Yes, obviously we could easily do this with a log function, but bare with me while I use this contrived example for simplicity. So let’s say we have a work function that will take a Tuple out of a bag, this Tuple will contain two ints.  The first int is the original number, and the second int is the last multiple of that number.  So we could load our bag with the initial values (let’s say we want to know the last multiple of each of 2, 3, 5, and 7 under 100. 1: var bag = new ConcurrentBag<Tuple<int, int>> 2: { 3: Tuple.Create(2, 1), 4: Tuple.Create(3, 1), 5: Tuple.Create(5, 1), 6: Tuple.Create(7, 1) 7: }; Then we can create a method that given the bag, will take out an item, apply the multiplier again, 1: public static void FindHighestPowerUnder(ConcurrentBag<Tuple<int,int>> bag, int threshold) 2: { 3: Tuple<int,int> pair; 4:  5: // while there are items to take, this will prefer local first, then steal if no local 6: while (bag.TryTake(out pair)) 7: { 8: // look at next power 9: var result = Math.Pow(pair.Item1, pair.Item2 + 1); 10:  11: if (result < threshold) 12: { 13: // if smaller than threshold bump power by 1 14: bag.Add(Tuple.Create(pair.Item1, pair.Item2 + 1)); 15: } 16: else 17: { 18: // otherwise, we're done 19: Console.WriteLine("Highest power of {0} under {3} is {0}^{1} = {2}.", 20: pair.Item1, pair.Item2, Math.Pow(pair.Item1, pair.Item2), threshold); 21: } 22: } 23: } Now that we have this, we can load up this method as an Action into our Tasks and run it: 1: // create array of tasks, start all, wait for all 2: var tasks = new[] 3: { 4: new Task(() => FindHighestPowerUnder(bag, 100)), 5: new Task(() => FindHighestPowerUnder(bag, 100)), 6: }; 7:  8: Array.ForEach(tasks, t => t.Start()); 9:  10: Task.WaitAll(tasks); Totally contrived, I know, but keep in mind the main point!  When you have a thread or task that operates on an item, and then puts it back for further consumption – or decomposes an item into further sub-items to be processed – you should consider a ConcurrentBag as the thread-local lists will allow for quick processing.  However, if you need ordering or if your processes are dedicated producers or consumers, this collection is not ideal.  As with anything, you should performance test as your mileage will vary depending on your situation! BlockingCollection<T> – A producers & consumers pattern collection The BlockingCollection<T> can be treated like a collection in its own right, but in reality it adds a producers and consumers paradigm to any collection that implements the interface IProducerConsumerCollection<T>.  If you don’t specify one at the time of construction, it will use a ConcurrentQueue<T> as its underlying store. If you don’t want to use the ConcurrentQueue, the ConcurrentStack and ConcurrentBag also implement the interface (though ConcurrentDictionary does not).  In addition, you are of course free to create your own implementation of the interface. So, for those who don’t remember the producers and consumers classical computer-science problem, the gist of it is that you have one (or more) processes that are creating items (producers) and one (or more) processes that are consuming these items (consumers).  Now, the crux of the problem is that there is a bin (queue) where the produced items are placed, and typically that bin has a limited size.  Thus if a producer creates an item, but there is no space to store it, it must wait until an item is consumed.  Also if a consumer goes to consume an item and none exists, it must wait until an item is produced. The BlockingCollection makes it trivial to implement any standard producers/consumers process set by providing that “bin” where the items can be produced into and consumed from with the appropriate blocking operations.  In addition, you can specify whether the bin should have a limited size or can be (theoretically) unbounded, and you can specify timeouts on the blocking operations. As far as your choice of “bin”, for the most part the ConcurrentQueue is the right choice because it is fairly light and maximizes fairness by ordering items so that they are consumed in the same order they are produced.  You can use the concurrent bag or stack, of course, but your ordering would be random-ish in the case of the former and LIFO in the case of the latter. So let’s look at some of the methods of note in BlockingCollection: BoundedCapacity returns capacity of the “bin” If the bin is unbounded, the capacity is int.MaxValue. Count returns an internally-kept count of items This makes it O(1), but if you modify underlying collection directly (not recommended) it is unreliable. CompleteAdding() is used to cut off further adds. This sets IsAddingCompleted and begins to wind down consumers once empty. IsAddingCompleted is true when producers are “done”. Once you are done producing, should complete the add process to alert consumers. IsCompleted is true when producers are “done” and “bin” is empty. Once you mark the producers done, and all items removed, this will be true. Add() is a blocking add to collection. If bin is full, will wait till space frees up Take() is a blocking remove from collection. If bin is empty, will wait until item is produced or adding is completed. GetConsumingEnumerable() is used to iterate and consume items. Unlike the standard enumerator, this one consumes the items instead of iteration. TryAdd() attempts add but does not block completely If adding would block, returns false instead, can specify TimeSpan to wait before stopping. TryTake() attempts to take but does not block completely Like TryAdd(), if taking would block, returns false instead, can specify TimeSpan to wait. Note the use of CompleteAdding() to signal the BlockingCollection that nothing else should be added.  This means that any attempts to TryAdd() or Add() after marked completed will throw an InvalidOperationException.  In addition, once adding is complete you can still continue to TryTake() and Take() until the bin is empty, and then Take() will throw the InvalidOperationException and TryTake() will return false. So let’s create a simple program to try this out.  Let’s say that you have one process that will be producing items, but a slower consumer process that handles them.  This gives us a chance to peek inside what happens when the bin is bounded (by default, the bin is NOT bounded). 1: var bin = new BlockingCollection<int>(5); Now, we create a method to produce items: 1: public static void ProduceItems(BlockingCollection<int> bin, int numToProduce) 2: { 3: for (int i = 0; i < numToProduce; i++) 4: { 5: // try for 10 ms to add an item 6: while (!bin.TryAdd(i, TimeSpan.FromMilliseconds(10))) 7: { 8: Console.WriteLine("Bin is full, retrying..."); 9: } 10: } 11:  12: // once done producing, call CompleteAdding() 13: Console.WriteLine("Adding is completed."); 14: bin.CompleteAdding(); 15: } And one to consume them: 1: public static void ConsumeItems(BlockingCollection<int> bin) 2: { 3: // This will only be true if CompleteAdding() was called AND the bin is empty. 4: while (!bin.IsCompleted) 5: { 6: int item; 7:  8: if (!bin.TryTake(out item, TimeSpan.FromMilliseconds(10))) 9: { 10: Console.WriteLine("Bin is empty, retrying..."); 11: } 12: else 13: { 14: Console.WriteLine("Consuming item {0}.", item); 15: Thread.Sleep(TimeSpan.FromMilliseconds(20)); 16: } 17: } 18: } Then we can fire them off: 1: // create one producer and two consumers 2: var tasks = new[] 3: { 4: new Task(() => ProduceItems(bin, 20)), 5: new Task(() => ConsumeItems(bin)), 6: new Task(() => ConsumeItems(bin)), 7: }; 8:  9: Array.ForEach(tasks, t => t.Start()); 10:  11: Task.WaitAll(tasks); Notice that the producer is faster than the consumer, thus it should be hitting a full bin often and displaying the message after it times out on TryAdd(). 1: Consuming item 0. 2: Consuming item 1. 3: Bin is full, retrying... 4: Bin is full, retrying... 5: Consuming item 3. 6: Consuming item 2. 7: Bin is full, retrying... 8: Consuming item 4. 9: Consuming item 5. 10: Bin is full, retrying... 11: Consuming item 6. 12: Consuming item 7. 13: Bin is full, retrying... 14: Consuming item 8. 15: Consuming item 9. 16: Bin is full, retrying... 17: Consuming item 10. 18: Consuming item 11. 19: Bin is full, retrying... 20: Consuming item 12. 21: Consuming item 13. 22: Bin is full, retrying... 23: Bin is full, retrying... 24: Consuming item 14. 25: Adding is completed. 26: Consuming item 15. 27: Consuming item 16. 28: Consuming item 17. 29: Consuming item 19. 30: Consuming item 18. Also notice that once CompleteAdding() is called and the bin is empty, the IsCompleted property returns true, and the consumers will exit. Summary The ConcurrentBag is an interesting collection that can be used to optimize concurrency scenarios where tasks or threads both produce and consume items.  In this way, it will choose to consume its own work if available, and then steal if not.  However, in situations where you want fair consumption or ordering, or in situations where the producers and consumers are distinct processes, the bag is not optimal. The BlockingCollection is a great wrapper around all of the concurrent queue, stack, and bag that allows you to add producer and consumer semantics easily including waiting when the bin is full or empty. That’s the end of my dive into the concurrent collections.  I’d also strongly recommend, once again, you read this excellent Microsoft white paper that goes into much greater detail on the efficiencies you can gain using these collections judiciously (here).

  • Tips on setting up a virtual lab for self-learning networking topics

    - by Harry
    I'm trying to self-learn the following topics on Linux (preferably Fedora): Network programming (using sockets API), especially across proxies and firewalls Proxies (of various kinds like transparent, http, socks...), Firewalls (iptables) and 'basic' Linux security SNAT, DNAT Network admininstration power tools: nc, socat (with all its options), ssh, openssl, etc etc. Now, I know that, ideally, it would be best if I had 'enough' number of physical nodes and physical network equipment (routers, switches, etc) for this self-learning exercise. But, obviously, don't have the budget or the physical space, nor want to be wasteful -- especially, when things could perhaps be simulated/emulated in a Linux environment. I have got one personal workstation, which is a single-homed Fedora desktop with 4GB memory, 200+ GB disk, and a 4-core CPU. I may be able to get 3 to 4 additional low-end Fedora workstations. But all of these -- including mine -- will always remain strictly behind our corporate firewall :-( Now, I know I could use VirtualBox-based virtual nodes, but don't know if there are any better alternatives disk- and memory- footprint-wise. Would you be able to give me some tips or suggestions on how to get started setting up this little budget- and space-constrained 'virtual lab' of mine? For example, how would I create virtual routers? Has someone attempted this sort of thing before: namely, creating a virtual network lab behind a corporate firewall for learning/development/testing purposes? I hope my question is not vague or too open-ended. Basically, right now, I don't know how to best leverage the Linux environment and the various 'goodies' it comes with, and buying physical devices only when it is absolutely necessary.

  • Bootable GRUB partition

    - by MA1
    I have a customized live fedora 12 USB which is working fine. What i want to do is to make a partition of my hard disk bootable so that my customized fedora can be run from hard disk. To accomplish this i did the following steps: Created a primary partition(/dev/sda2) and format it as ext3 and set it as active. Copy all the files in the live usb to /dev/sda2. Following are the live usb contents(all directories): a. boot b. EFI c. LiveOS d. syslinux Then i installed the GRUB in boot/grub Created the grub.conf in boot/grub Following are the contents of each directory in the USB: syslinux/ boot.cat isolinux.bin splash.jpg vesamenu.c32 initrd0.img ldlinux.sys syslinux.cfg vmlinuz0 LiveOS/ livecd-iso-to-disk osmin.img squashfs.img EFI/ boot/ boot.conf grub.conf boot.efi bootia32.conf bootia32.efi splash.jpg splash.xpm.gz vesamenu.c32 initrd0.img isolinux.bin isolinux.cfg vmlinuz0 boot/grub/ core GRUB files grub.conf olpc.fth Following are contents of grub.conf default=0 splashimage=/EFI/boot/splash.xpm.gz timeout 2 hiddenmenu title funLinux kernel /EFI/boot/vmlinuz0 root=live:LABEL=myFun rootfstype=auto ro liveimg quiet ssb.blacklist=1 selinux=0 vga=normal nomodeset rhgb initrd /EFI/boot/initrd0.img Now when i try to boot from the hard disk it shows the grub menu and fedora starting to load but during loading it said No root device found Boot has failed, sleeping forever So, where is the problem? what i am doing wrong?

  • Bad font anti-aliasing in Ubuntu

    - by Juliano
    I'm switching from Fedora 8 to Ubuntu 9.04, and I can't seem to get it to get a good font anti-aliasing to work. It seems that Ubuntu's fontconfig tries to keep characters in integral pixel widths. This makes text more difficult to read, when 1 pixel is too thin and 2 pixels is too thick. Check the image below. In Fedora, when fontconfig anti-aliasing is enabled, fonts have their thickness proportional to the font size. Below, the thickness is different for 8, 9 and 10pt sizes. In Ubuntu, on the other hand, even when anti-aliasing is enabled, all 8, 9 and 10pt sizes have 1 pixel thickness. This makes reading larges amount of text difficult. I'm using the very same home directory, and I already checked that X resources are the same in both systems: ~% xrdb -query | grep Xft Xft.antialias: 1 Xft.dpi: 96 Xft.hinting: 1 Xft.hintstyle: hintfull Xft.rgba: none GNOME settings: ~% gconftool-2 -a /desktop/gnome/font_rendering antialiasing = grayscale hinting = full dpi = 96 rgba_order = rgb So, the question is: What should I change in the new box (Ubuntu) in order to get anti-aliasing like in the old box (Fedora)?

  • Creating Custom ISO Images

    - by ericl42
    I am working on creating some custom ISO images using primarily Fedora and CentOS. I want the image to be a bootable live CD with some specific files on it. I also want it to have the option to be able to be downloaded to the hard drive. I've read some various articles but want to get a few more opinions since I've never done this before. Currently I'm trying 2 different methods. Install Fedora with the configuration exactly how I want it and then run the livecd-tools program to pull everything I currently have to an ISO. I haven't got this to work yet but I do see a few issues with it. Such as the default passwords I had to put in. Run a Fedora live CD and install a few things I want on it and then copy the image of it. I believe this would work better since it has more of a live cd feel. However I"m not 100% sure how I should go about pulling the current image to my own ISO. I know some people have said to use mkisofs and a few other programs but any advice would be greatly appreciated.

  • Shut Out of XP - No Admin Password or CDR

    - by ashes999
    I inherited an old WinXP/Linux dual-boot machine from the stoneage. Because it has Linux, the regular boot process is replaced with the Fedora boot loader; I cannot, therefore, press F8 strategically to tell my PC to boot from CD. Even if I could, it's a moot point; the CDR doesn't seem to recognize any CDs. To make things worse, there's no option to network boot. The original user is probably long gone; I don't know the password for any of the Administrator group users. I can login using my corp account, but that's unprivileged on this machine. Since I'm not an admin, I can't do crazy things, like looking at boot.ini. Or deleting files. I only have 500MB free on my C drive. I'm pretty sure I can't boot from a USB, since I didn't see any settings for this in my BIOS. How can I get admin access for my user? Edit: Things I've tried: Boot from CD (CD not recognized) Launch CD from XP (CD not recognized) Install Daemon Tools Lite so I can install from an ISO -- don't have admin privileges XP password recovery tool -- requires admin privileges Adding an admin user -- no access to Control Panel Users since I'm not an admin Logging in as both the admin users on the system (trying some standard passwords) Using Fedora to chntpw (the Fedora version installed is ancient -- 2.7)

  • Very Slow DSL (ethernet) speed [New Interesting Update]

    - by Abhijit
    Very IMPORTANT and INTERESTING UPDATE: Due to some reason I just thought to do a complete new setup and this time I decided to again have openSUSE plus ubuntu. So I first reinstall lubuntu and then I installed OpenSUSE 12.2 (64 bit). Now, my DSL speed is working very normal and fine on opensuse. So this is very scary. Is it possible for any operating system to manipulate my NIC so that it will work fine only on that operating system and not on another os? Regarding positive thinking and not being paranoid, what is it that makes ONLY suse to get my NIC to work at normal speed but ubuntu can not do it? Not even fedora? Not even linux mint? What all these OS are lacking that enables suse to work great? == ORIGINAL QUESTION == I 'was' on opensuse 12.2 when my dsl speed was normal. Yesterday I switched from opensuse to ubuntu 12.04 and speed decreased. It came to range of 7-10-13-20-25-kbps. Then I switch to linux mint, and then to fedora. Still slow speed. When I was in ubuntu I disabled ipv6 but still no luck. Now I am in fedora but this time with DIFFERENT ISP. And still I am getting very slow sped. So my guess is this is nothing to do with os. What can be wrong? Is this problem of NIC? Does NIC speed decreases over time? Does NIC life ends over time as with keyboard or mouse? Help please All the os I used are 64 bit and my laptop is Compaq Presario A965Tu Intel Centrino DUal Core. Interesting thing to notice is I get normal speed while downloading torrent inside torrent client softwares. This slow speed issue applied to download from any web browser or installing software using terminal.

  • Unable to ssh to a Linux VM after a day

    - by jogabonito
    I have a machine running 4 VMs on it. There is one Fedora VM which is causing me some trouble. The IPs of the VMs are something like 10.100.100.* I have a Windows PC which is in the same network. It has an IP 10.100.25.77. When I reboot the Fedora VM, I am able to ping it from my Windows PC as well as use putty to ssh to it. The next day, I cant ping it or ssh from my Windows PC. However I can ping and ssh to the other VMs on the machine. If I ssh to one of the other VMs, I can ping and ssh to the Fedora VM. Next if I restart it, things get back to normal and I can access it without any issues. The IP of the VM doesn't change after rebooting and it is statically assigned I would like to know what is causing this and how to get it fixed. As a last resort, I am thinking of running a cron job to restart the VM every night, it is not a critical server, but will be generally used occasionally in the day time.

  • linux shutdown hang with wifi cifs mounts

    - by Sirex
    Since fedora 15 (and now with 16) it seems that wireless clients take a long while to shutdown when they have network filesystems mounted at shutdown time. I've pushed out a cifs mount via puppet, and all clients have it, including those on wireless. If say a laptop is on a wired connection it shuts down just fine, but if its on the wifi at the time (and no wired connection) it'll hang at the fedora f logo. I'm not sure if its indefinite or just a really long while, but ill give it a test when i shut this machine down in a second. Needless to say its pretty annoying, so is there a way of causing the machine to shutdown even if network connectivity has been lost at unmount time, -- or an official way to reorder events so the wireless card is kept up until after the unmount happens during the shut down process (short of writing a custom script for shutdowns which is a bit of a kludge) ? It does this on multiple machines, and all started doing it when we went from fedora 14 to 15. It was such an obvious issue i'd kind of assumed someone must have reported it or there was an easy fix, but i've not discovered anything yet. Additional info: I can confirm that manually unmounting the mounts then shutting down (sudo shutdown or the xfce shutdown button) will shutdown just fine, it only hangs if the mounts are still mounted The puppet config that sets the mount looks like this (now with the _netdev entry that is indeed pushed to clients successfully, but makes no difference): file { "/mnt/share": ensure = directory,} mount { "/mnt/share": atboot = true, ensure = mounted, remounts = false, fstype = cifs, device = "//srv/share", options = "user,gid=shareusers,uid=${user},file_mode=0700,dir_mode=0700,credentials=/root/.smbcreds,_netdev", require = [ File["/mnt/share"], Group["shareusers"] ], } }

  • Burning Linux ISO to DVD and making it bootable.

    - by toc777
    Hi everyone, I just downloaded the Fedora 14 Live-Desktop ISO and used CDBurnerXP to burn the image to a DVD. For some reason the first time I burned the image nothing showed up on the DVD when I accessed it even though CDBurnerXP said it had successfully burned to the disk. I did it again and the ISO shows up on the disk (I don't think this is right, should it be the files inside the image that show up on disk or the image file??). The problem now is my dell PC can't find the ISO when I try to boot from it. I get an error saying it can't boot from the CD. I have verified the ISO image as directed from the Fedora website. My question is how do I make a bootable CD from a Fedora Live-Desktop ISO? How can I verify that the ISO was written to the CD correctly and has anyone had any issues booting from a CD using a Dell desktop (I'm not at home at the moment so I can't check what model it is but its old enough, I've had it for about 5 years). EDIT: All that needed to be done was to burn the image to CD as an image and not a data file. The first three times failed, I'm not sure if this was because of faulty DVD's or if the write speed was too high (16x). I put in a new DVD and changed the write speed to 8x, the image was then properly burned to the disk without any errors. Thanks.

  • IRQ problem with 2.6.32/2.6.39 kernel on Debian Squeeze x86_64

    - by MasterM
    I recently assembled a new computer so that all hardware is pretty new. Since then I've been experiencing some problem with IRQs when running Debian 6.0.

When I restart Xorg everything is fine again and the problem doesn't occur until next reboot. I tried to upgrade the kernel from stock 2.6.32 to 2.6.39 from unstable repository but that didn't help. Booting with irqpoll option only seems to prolong the initial time period after which the problem occurs. I'm using latest NVIDIA drivers and Realtek firmware from firmware-realtek package. I have two GTX 560Ti that run in SLI. Disabling SLI or taking out one card completely doesn't solve the problem either.

  • ubuntu 10.04 logs itself out overnight

    - by Corey
    Every night when I leave work, I lock the screen via ubuntu's "power" button in the top right hand panel. When I come to work in the morning, I'm greeted with the log-in screen. This doesn't happen every night, but most. I'm running ubuntu 10.04 on a Dell inspiron. I've included some HW specs, and also dmesg output. Please let me know what other logs may be useful. thanks!

  • EC2 instance suddenly refusing SSH connections and won't respond to ping

    - by Chris
    My instance was running fine and this morning I was able to access a Ruby on Rails app hosted on it. An hour later I suddenly wasn't able to access my site, my SSH connection attempts were refused and the server wasn't even responding to ping. I didn't change anything on my system during that hour and reboots aren't fixing it. I've never had any problems connecting or pinging the system before. Can someone please help? This is on my production system!

  • Trying to configure HWIC-3G-HSPA

    - by user1174838
    I'm trying to configure a couple of Cisco 1941 routes. The are both identical routers. Each as a HWIC-1T (Smart Serial interface) and a HWIC-3G-HSPA 3G interface. These routers are to be sent to remote sites. We have connectivity to one of the sites but if remote site A gors down we lose connectivity to remote site B. The HWIC-1T is the primary WAN interface using frame relay joining the two remote sites We want the HWIC-3G-HSPA to be usable for direct connectivity from head office to remote site B, and also the HWIC-3G-HSPA is do be used for comms between the remote sites when the frame relay is down (happens quite a bit). I initialy tried to do dynamic routing using EIGRP however in my lab setup of laptop - 1941 - 1941 - laptop, I was unable to get end to end connectivity. I later settled on static routing and have got end to end connectivity but only over frame relay, not the HWIC-3G-HSPA. The sanitized running config for remote site A: version 15.1 service tcp-keepalives-in service tcp-keepalives-out service timestamps debug datetime msec service timestamps log datetime msec service password-encryption service udp-small-servers service tcp-small-servers !

I've tried using kron to ping the local HWIC-3G-HSPA interface (cellular 0/1/0) every minute but that hasn't been successful. Manually pinging the IP assigned (by the telco) to ce0/1/0 does bring the interface up. Any ideas? Thanks

  • How to prevent Android bluetooth RFCOMM connection from dying immediately after .connect()?

    - by Gilead
    I'm trying to connect to a Zeemote (http://zeemote.com/) gaming controller from Moto Droid running 2.0.1 firmware. The test application below does connect to the device (LED flashes) but connection is dropped immediately after that.

  • Spring Security - Interactive login attempt was unsuccessful

    - by Taylor L
    I've been trying to track down why Spring Security isn't creating the SPRING_SECURITY_REMEMBER_ME_COOKIE so I turned on logging for org.springframework.security.web.authentication.rememberme. At first glance, the logs make it seem like the login is failing but the login is actually successful in the sense that if I navigate to a page that requires authentication I am not redirected back to the login page. However, the logs appear to be saying the login credentials are invalid. Any ideas as to what is going on?

  • [OpenGL ES - Android] Better way to generate tiles

    - by Inoe
    Hi ! I'll start by saying that i'm REALLY new to OpenGL ES (I started yesterday =), but I do have some Java and other languages experience. I've looked a lot of tutorials, of course Nehe's ones and my work is mainly based on that. As a test, I started creating a "tile generator" in order to create a small Zelda-like game (just moving a dude in a textured square would be awsome :p). So far, I have achieved a working tile generator, I define a char map[][] array to store wich tile is on : private char[][] map = { {0, 0, 20, 11, 11, 11, 11, 4, 0, 0}, {0, 20, 16, 12, 12, 12, 12, 7, 4, 0}, {20, 16, 17, 13, 13, 13, 13, 9, 7, 4}, {21, 24, 18, 14, 14, 14, 14, 8, 5, 1}, {21, 22, 25, 15, 15, 15, 15, 6, 2, 1}, {21, 22, 23, 0, 0, 0, 0, 3, 2, 1}, {21, 22, 23, 0, 0, 0, 0, 3, 2, 1}, {26, 0, 0, 0, 0, 0, 0, 3, 2, 1}, {0, 0, 0, 0, 0, 0, 0, 0, 0, 1}, {0, 0, 0, 0, 0, 0, 0, 0, 0, 1} }; It's working but I'm no happy with it, I'm sure there is a beter way to do those things : 1) Loading Textures : I create an ugly looking array containing the tiles I want to use on that map : private int[] textures = { R.drawable.herbe, //0 R.drawable.murdroite_haut, //1 R.drawable.murdroite_milieu, //2 R.drawable.murdroite_bas, //3 R.drawable.angledroitehaut_haut, //4 R.drawable.angledroitehaut_milieu, //5 }; (I cutted this on purpose, I currently load 27 tiles) All of theses are stored in the drawable folder, each one is a 16*16 tile. I then use this array to generate the textures and store them in a HashMap for a later use : int[] tmp_tex = new int[textures.length]; gl.glGenTextures(textures.length, tmp_tex, 0); texturesgen = tmp_tex; //Store the generated names in texturesgen for(int i=0; i < textures.length; i++) { //Bitmap bmp = BitmapFactory.decodeResource(context.getResources(), textures[i]); InputStream is = context.getResources().openRawResource(textures[i]); Bitmap bitmap = null; try { //BitmapFactory is an Android graphics utility for images bitmap = BitmapFactory.decodeStream(is); } finally { //Always clear and close try { is.close(); is = null; } catch (IOException e) { } } // Get a new texture name // Load it up this.textureMap.put(new Integer(textures[i]),new Integer(i)); int tex = tmp_tex[i]; gl.glBindTexture(GL10.GL_TEXTURE_2D, tex); //Create Nearest Filtered Texture gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_NEAREST); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); //Different possible texture parameters, e.g. GL10.GL_CLAMP_TO_EDGE gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_REPEAT); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_REPEAT); //Use the Android GLUtils to specify a two-dimensional texture image from our bitmap GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0); bitmap.recycle(); } I'm quite sure there is a better way to handle that... I just was unable to figure it. If someone has an idea, i'm all ears. 2) Drawing the tiles What I did was create a single square and a single texture map : /** The initial vertex definition */ private float vertices[] = { -1.0f, -1.0f, 0.0f, //Bottom Left 1.0f, -1.0f, 0.0f, //Bottom Right -1.0f, 1.0f, 0.0f, //Top Left 1.0f, 1.0f, 0.0f //Top Right }; private float texture[] = { //Mapping coordinates for the vertices 0.0f, 1.0f, 1.0f, 1.0f, 0.0f, 0.0f, 1.0f, 0.0f }; Then, in my draw function, I loop through the map to define the texture to use (after pointing to and enabling the buffers) : for(int y = 0; y < Y; y++){ for(int x = 0; x < X; x++){ tile = map[y][x]; try { //Get the texture from the HashMap int textureid = ((Integer) this.textureMap.get(new Integer(textures[tile]))).intValue(); gl.glBindTexture(GL10.GL_TEXTURE_2D, this.texturesgen[textureid]); } catch(Exception e) { return; } //Draw the vertices as triangle strip gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, 0, vertices.length / 3); gl.glTranslatef(2.0f, 0.0f, 0.0f); //A square takes 2x so I move +2x before drawing the next tile } gl.glTranslatef(-(float)(2*X), -2.0f, 0.0f); //Go back to the begining of the map X-wise and move 2y down before drawing the next line } This works great by I really think that on a 1000*1000 or more map, it will be lagging as hell (as a reminder, this is a typical Zelda world map : http://vgmaps.com/Atlas/SuperNES/LegendOfZelda-ALinkToThePast-LightWorld.png ). I've read things about Vertex Buffer Object and DisplayList but I couldn't find a good tutorial and nodoby seems to be OK on wich one is the best / has the better support (T1 and Nexus One are ages away). I think that's it, I've putted a lot of code but I think it helps. Thanks in advance !

  • How do I insert a row with a TimeUUIDType column in Cassandra?

    - by mixmasteralan
    In Cassandra, I have the following Column Family: <ColumnFamily CompareWith="TimeUUIDType" Name="Posts"/> I'm trying to insert a record into it as follows using a C++ generated function generated by Thrift: ColumnPath new_col; new_col.__isset.column = true; /* this is required! */ new_col.column_family.assign("Posts"); new_col.super_column.assign(""); new_col.column.assign("1968ec4a-2a73-11df-9aca-00012e27a270"); client.insert("Keyspace1", "somekey", new_col, "Random Value", 1234, ONE); However, I'm getting the following error: "UUIDs must be exactly 16 bytes" I've even tried the Cassandra CLI with the following command: set Keyspace1.Posts['somekey']['1968ec4a-2a73-11df-9aca-00012e27a270'] = 'Random Value' but I still get the following error: Exception null InvalidRequestException(why:UUIDs must be exactly 16 bytes) at org.apache.cassandra.thrift.Cassandra$insert_result.read(Cassandra.java:11994) at org.apache.cassandra.thrift.Cassandra$Client.recv_insert(Cassandra.java:659) at org.apache.cassandra.thrift.Cassandra$Client.insert(Cassandra.java:632) at org.apache.cassandra.cli.CliClient.executeSet(CliClient.java:420) at org.apache.cassandra.cli.CliClient.executeCLIStmt(CliClient.java:80) at org.apache.cassandra.cli.CliMain.processCLIStmt(CliMain.java:132) at org.apache.cassandra.cli.CliMain.main(CliMain.java:173)

  • Spring Security - Persistent Remember Me Issue

    - by Taylor L
    I've been trying to track down why Spring Security isn't creating the Spring Security remember me cookie (SPRING_SECURITY_REMEMBER_ME_COOKIE). At first glance, the logs make it seem like the login is failing, but the login is actually successful in the sense that if I navigate to a page that requires authentication I am not redirected back to the login page. However, the logs appear to be saying the login credentials are invalid. I'm using Spring 3.0.1, Spring Security 3.0.1, and Google App Engine 1.3.1. Any ideas as to what is going on?

  • Strange remoting connection problem

    - by Voyager Systems
    In trying to configure a .NET remoting setup over TCP, I've been having problems accepting outside connections (connections from any computer not on my LAN). I did some investigation and hit netstat -a as soon as my friend started to connect. Here's what I saw: TCP 0.0.0.0:2594 Taylor-PC:0 LISTENING ... TCP 192.168.1.102:2594 24-155-7-16:63588 ESTABLISHED TCP 192.168.1.102:62488 192.168.0.100:1554 SYN_SENT Now here's the weird part: 24.155.7.16 is my friend's IP (modified) and it says the connection is established. But the connection hangs until it times out. I then found out that 192.168.0.100 is his local address on his network. Something screwy's going on somewhere. My server and client are both TCPChannels, the latter initialized 'new TCPChannel( 0 ).' Localhost connections work when I run a client on the same machine as the server, but I can't accept remote connections. There is no port forwarding or firewall issue. Thanks for the help

  • Read half precision float (float16 IEEE 754r) binary data in matlab

    - by Michael
    you have been a great help last time, i hope you can give me some advise this time, too. I read a binary file into matlab with bit16 (format = bitn) and i get a string of ones and zeros. bin = '1 00011 1111111111' (16 bits: 1. sign, 2-6. exponent, 7-16. mantissa) According to ftp://www.fox-toolkit.org/pub/fasthalffloatconversion.pdf it can be 'converted' like out = (-1)^bin(1) * 2^(bin(2:6)-15) * 1.bin(7:16) [are exponent and mantissa still binary?] Can someone help me out and tell me how to deal with the 'eeeee' and '1.mmmmmmmmmm' as mentioned in the pdf, please. Thanks a lot! Michael

  • MP4 plays on Safari 4 (desktop) but not on Safari Mobile (iphone)

    - by deb
    I'm encoding the video with ffmpeg and displaying it using the HTML 5 video tag. It works fine on Firefox (i'm also providing a ogg version) and Safari 4. However, when I try to open it on the iphone I get a "Cannot Play Movie" error. Here is the ffmpeg command I'm using: ffmpeg -y -i movie.mov -acodec libfaac -ar 44100 -ab 96k -vcodec libx264 -vpre hq -level 41 -crf 20 -bufsize 20000k -maxrate 1500k -g 250 -s 320X200 -coder 1 -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -flags2 +dct8x8+bpyramid -me_method umh -subq 7 -me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -rc_eq 'blurCplx^(1-qComp)' -bf 16 -b_strategy 1 -bidir_refine 1 -refs 6 -deblockalpha 0 -deblockbeta 0 movie.mp4 I reduced the maxrate to 1500 because I read that if the bit rate is too high the iphone won't play the video, but still didn't work. I don't know where else to look... any ideas? Thanks in advance
