  • Trouble with go tour crawler exercise

    - by David Mason
    I'm going through the go tour and I feel like I have a pretty good understanding of the language except for concurrency. On slide 71 there is an exercise that asks the reader to parallelize a web crawler (and to make it not cover repeats but I haven't gotten there yet.) Here is what I have so far: func Crawl(url string, depth int, fetcher Fetcher, ch chan string) { if depth <= 0 { return } body, urls, err := fetcher.Fetch(url) if err != nil { ch <- fmt.Sprintln(err) return } ch <- fmt.Sprintf("found: %s %q\n", url, body) for _, u := range urls { go Crawl(u, depth-1, fetcher, ch) } } func main() { ch := make(chan string, 100) go Crawl("http://golang.org/", 4, fetcher, ch) for i := range ch { fmt.Println(i) } } The issue I have is where to put the close(ch) call. If I put a defer close(ch) somewhere in the Crawl method, then I end up writing to a closed channel in one of the spawned goroutines, since the method will finish execution before the spawned goroutines do. If I omit the call to close(ch), as is shown in my example code, the program deadlocks after all the goroutines finish executing but the main thread is still waiting on the channel in the for loop since the channel was never closed.

  • OpenCV compare two images and get different pixels

    - by Richard Knop
    For some reason the code bellow is not working. I have two 640*480 images which are very similar but not the same (at least few hundred/thousand pixels should be different). This is how I am comparing them and counting different pixels: unsigned char* row; unsigned char* row2; int count = 0; // this happens in a loop // fIplImageHeader is current image // lastFIplImageHeader is image from previous iteration if ( NULL != lastFIplImageHeader->imageData ) { for( int y = 0; y < fIplImageHeader->height; y++ ) { row = &CV_IMAGE_ELEM( fIplImageHeader, unsigned char, y, 0 ); row2 = &CV_IMAGE_ELEM( lastFIplImageHeader, unsigned char, y, 0 ); for( int x = 0; x < fIplImageHeader->width*fIplImageHeader->nChannels; x += fIplImageHeader->nChannels ) { if (row[x] == row2[x]) // the pixel in the first channel (usually G) { count++; } if (row[x+1] == row2[x+1]) // ... second channel (usually B) { count++; } if (row[x+2] == row2[x+2]) // ... third channel (usually R) { count++; } } } } Now at the end I get number 3626 which would seem alright. But, I tried opening one of the images in MS Paint and drawing thick red lines all over it which should increase the number of different pixels substantially. I got the same number again: 3626. Obviously I am doing something wrong here. I am comparing these images in a loop. This line is before the loop: IplImage* lastFIplImageHeader = cvCreateImageHeader(cvSize(640, 480), 8, 3); Then inside the loop I load images like this: IplImage* fIplImageHeader = cvLoadImage( filePath.c_str() ); // here I compare the pixels (the first code snippet) lastFIplImageHeader->imageData = fIplImageHeader->imageData; So lastFIplImageHeader is storing the image from the previous iteration and fIplImageHeader is storing the current image.

  • Automatic Standby Recreation for Data Guard

    - by pablo.boixeda(at)oracle.com
    Hi,Unfortunately sometimes a Standby Instance needs to be recreated. This can happen for many reasons such as lost archive logs, standby data files, failover, among others.This is why we wanted to have one script to recreate standby instances in an easy way.This script recreates the standby considering some prereqs:-Database Version should be at least 11gR1-Dummy instance started on the standby node (Seeking to improve this so it won't be needed)-Broker configuration hasn't been removed-In our case we have two TNSNAMES files, one for the Standby creation (using SID) and the other one for production using service names (including broker service name)-Some environment variables set up by the environment db script (like ORACLE_HOME, PATH...)-The directory tree should not have been modified in the stanby hostWe are currently using it on our 11gR2 Data Guard tests.Any improvements will be welcome!

  • Un-failing over a Cisco PIX 515e

    - by ABrown
    We had a power outage at our data center last week and when our dual PIX 515E running IOS 7.0(8) (configured with a failover cable) came back, they were in a failed over state where the Secondary unit is active and the Primary unit is standby I have tried 'failover reset', 'failover active', and 'failover reload-standby' as well as executing reloads on both units in a variety of orders, and they don't come back Primary/Active Secondary/Standby. The only thing in my arsenal that I haven't tried is driving to the data center and performing a hard reboot, which I hate to do. I have read How Failover Works on the Cisco Secure Firewall and it seems like this should be wicked straight forward. output of show failover on Primary: Failover On Cable status: Normal Failover unit Primary Failover LAN Interface: N/A - Serial-based failover enabled Unit Poll frequency 15 seconds, holdtime 45 seconds Interface Poll frequency 15 seconds Interface Policy 1 Monitored Interfaces 2 of 250 maximum Version: Ours 7.0(8), Mate 7.0(8) Last Failover at: 02:52:05 UTC Mar 10 2010 This host: Primary - Standby Ready Active time: 0 (sec) Interface outside (x.x.x.165): Normal Interface inside (y.y.y.3): Normal Other host: Secondary - Active Active time: 897045 (sec) Interface outside (x.x.x.164): Normal Interface inside (y.y.y.4): Normal Stateful Failover Logical Update Statistics Link : Unconfigured. output of show failover on Secondary: Failover On Cable status: Normal Failover unit Secondary Failover LAN Interface: N/A - Serial-based failover enabled Unit Poll frequency 15 seconds, holdtime 45 seconds Interface Poll frequency 15 seconds Interface Policy 1 Monitored Interfaces 2 of 250 maximum Version: Ours 7.0(8), Mate 7.0(8) Last Failover at: 02:03:04 UTC Feb 28 2010 This host: Secondary - Active Active time: 896925 (sec) Interface outside (x.x.x.164): Normal Interface inside (y.y.y.4): Normal Other host: Primary - Standby Ready Active time: 0 (sec) Interface outside (x.x.x.165): Normal Interface inside (y.y.y.3): Normal Stateful Failover Logical Update Statistics Link : Unconfigured.

  • 8Gb Fiber Channcel HBA vs. 10 Gb SPF+ Converged HBA

    - by Hossein Aarabi
    I am putting a Dell server together, more specifically R720. I have to select the correct Host Bus Adapter. This HBA on R710 will connect to a storage device. I am confused between these two: QLogic 2562, Dual Port 8Gb Optical Fiber Channel HBA (price $2,045) QLogic 8262, Dual Port 10Gb SFP+, Converged Network Adapter (price $1,618) I thought since the QLogic 2562 is a fiber channel and is more expensive then it is faster in terms of IOPS. But, it is a 8Gb as opposed to 10 Gb of SFP+. My questions: Which one is better (IOPS performance, etc.)? Why should I choose one over another?

  • AIX: iscsi volumes disappear after reboot

    - by Dan
    We have an IBM P505 AIX box, with two internal disks and a defined iSCSI volume. The iSCSI volume is defined in it's own volume group, and is connected to an IBM iSCSI DS3300 disk array via the secondary onboard ethernet port (ie, we're not using a dedicated HBA, we're using the second onboard ethernet port for iSCSI exclusively.) When we reboot the AIX box, the iSCSI volume doesn't get mounted (which is fine; I've figured out that it fails to mount because AIX tries mounting it's volumes before starting the networking stack.) The problem is, after the server has booted it fails to redetect the iSCSI target as a physical disk. This means the volume group (iscsivg) can't go online. if I run cfgmgr -v to redetect the iscsi volume it successfully detects the iscsi target volume and creates a physical volume reference, but allocates it a different volume ID to what was defined before. eg - rootvg contains hdisk 0 and 1 iscsivg was originally defined with hdisk2 as the physical iSCSI volume. after reboot and running cfgmgr -v, AIX detects physical volumes hdisk0, hdisk11 and hdisk3. As there's no hdisk2, I can't varyon the iscsivg volume group. I can't seem any existing hdisk2 definition in the ODM. I can't easily add or change the definition of the physcial disk in the iscsivg volume group as it won't "varyon". Exporting the volume group deletes it completely, recreating the volume group by "importing" it from the reallocated disk makes it available again, but surely there's a better way? Can I force a specific hdisk drive designation for an iscsi target? How do you bring online iSCSI volumes after a reboot? I assume this "just works" with a dedicated HBA instead of a generic ethernet adapter? By the way, the iSCSI volume works fine once it's mounted; we only have problems getting it working - and only with AIX. The iSCSI array works fine with our Linux and Windows servers; ie the volumes get detected and remounted after boot time without any problems, using generic ethernet adapters. Here's some of the config from the AIX box: defined disks / devices: # lsdev hdisk0 Available 06-08-01-5,0 16 Bit LVD SCSI Disk Drive hdisk1 Available 06-08-01-8,0 16 Bit LVD SCSI Disk Drive hdisk3 Available Other iSCSI Disk Drive iscsi0 Available iSCSI Protocol Device scsi0 Available 06-08-00 PCI-X Dual Channel Ultra320 SCSI Adapter bus scsi1 Available 06-08-01 PCI-X Dual Channel Ultra320 SCSI Adapter bus ses0 Available 06-08-01-15,0 SCSI Enclosure Services Device sisscsia0 Available 06-08 PCI-X Dual Channel Ultra320 SCSI Adapter iscsi target definition in /etc/iscsi/targets: # IBM DS3300 disk array # port 1 on second controller 10.10.xx.xxx 3260 iqn.1992-01.com.lsi:1535.600a0b80005b0a7fxxxxxxxxxxxx physical volumes (after reimporting the volume group) # lspv hdisk0 0003b08a0d4936b6 rootvg active hdisk1 0003b08aaa5cb366 rootvg active hdisk3 0003b08a032d04bb iscsivg active

  • Recommended SpamAssassin update channels?

    - by Timo Geusch
    I'm currently using SpamAssassin on a couple of mail servers that I look after. SpamAssassin runs in the context of amavisd-new on those servers and with the usual bunch of plugins (FuzzyOCR, DCC, pyzor, razor). Currently the servers are getting their rule updates from the default SpamAssassin update channel (updates.spamassassin.org). Overall the setup seems to be reasonably effective but some types of spam seem to wander right through it even though I've made repeated attempts at training spamassassin. My guesstimate is that about 85%-90% of the spam that gets through policyd-weight makes it through the filters and it's been getting a lot worse recently as spammers are getting better at working their way through filters. Can someone recommend additional sources of filters to make SpamAssassin more effective? So far I've found OpenProtect's update channel but are there others worth looking at?

  • Trying to install pdo_oci via PECL fails asking for PDO extension

    - by Igoru
    I'm using Linux Mint 11 (based on Ubuntu 11.04) and I need to use PHP with Oracle through PDO, a requirement of the framework we will work with. I've installed various PDO extensions using the normal apt-get method, like php5-mysql, etc, and they loaded just fine, along with the initial PDO extension. But there's no package for Oracle bindings. So, when I try to run sudo pecl install pdo_oci it throws me this: WARNING: "pear/PDO_OCI" is deprecated in favor of "channel://http://www.php.net/pdo_oci/ext/pdo_oci" pear/PDO_OCI requires PHP extension "pdo" (version >= 1.0) No valid packages found install failed How can I add this channel, or is there a better way to install the PDO_OCI extension?

  • Ping only works after about 30 seconds

    - by Ricardo Polo
    Today I am working on this issue and I would love your ideas. There is a network with something like this LAN 1 -- WAN CHANNEL--- LAN 2 The LAN 1 have two segments. When I make a ping from LAN 1 segment 1 it works like a charm. When I make a ping from LAN 1 segment 2 I have no ping, but after about 30 seconds of continues ping (ping -t) it start to work perfect. After some time of no activity with the destination host the issue happens again. Tracing the route packets stops in the last router before the target. This is the first router in LAN 2 after the WAN channel. In the next screenshot you can see thie issue, the first ping is before a continuos ping and the second one is while continous ping is running. Thank you in advance

  • Router's ssid changes from infrastructure to ad-hoc

    - by waldo
    For a period of time the router's ssid is shown (on various computers) as a normal infrastructure network - computers connect fine and everything works however after a few minutes / hours all computers see the same ssid as an ad-hoc network (not infrastructure). At this point a computer that was already connected continues to work - a computer that isn't cannot connect. Rebooting the router temporarily restores the visibility of the correct infrastructure ssid. Is something interfering? Connecting computers: macbook (2009), iphone 3g, windows vista desktop, windows xp desktop.

  • Problems when trying to connect to a router wirelessly

    - by Ruud Lenders
    The situation - At my girlfriend's parents' place there are six Windows 7 devices that are wired or wireless connected to a router: 3 dekstops and 3 laptops. There are also several smartphones using the router. The router is secured with WPA2 (AES). The problem - We never had any problems with the router for over a year. But recently - about 3 weeks ago - my girlfriend's laptop (HP) and my laptop (ASUS) started to develop problems while trying to connect to the router. The router has stopped showing up from the network list. Sometimes it comes back and shows up, but then it keeps saying something along the lines of "Could not connect", and not long after that it dissapears again. The range of the router is not the problem here, because we experience the same when we sit next to the router. Sometimes, if we are lucky, and waited a long time (10-15 minutes) without using the laptop for anything, the laptop will eventually succesful connect to the router. The attempts - Of course, the Window 7 troubleshooter. We tried troubleshooting the connection problems and the wireless network adapter, but no luck. We also reset the router enough times to know that's not helping either. Here's the full list of things we tried, but did not help: Running the Windows 7 troubleshooter Resetting the router (more than once) Setting the router settings to factory defaults Disconnecting all other devices except one laptop Applying a system restore Trying static/dynamic IP/DNS - Dynamic is better, right? Enabling/disabling IPv6 - Should I keep IPv6 disabled? Running the command: netsh wlan stop hostednetwork Running the command: netsh wlan set hostednetwork mode=disallow Updating/reïnstalling wireless adapter drivers The tests - To help finding the core of the problem, we tested the following: Plugging an ethernet cable in the router and in our laptops - worked fine Connecting someone else's laptop to the router (wireless) - worked fine Connecting our laptops to someone else's router - worked fine The router - This information might be relevant: Router model: Sitecom 300N Wireless Router Router hardware: version 01 The DCHP Server's IPs range from 192.168.0.100 to 192.168.0.200. Router settings: Wireless channel: 12 Channel bandwidth: 20/40 MHz Extension channel: 8 Preamble type: Long 802.11g protection: Disabled UPnP: Enabled The laptops - If you are wondering about our laptops: My laptop model: ASUS Pro64JQ Girlfriend's laptop: HP Pavillion G6 OS: Both Windows 7 Professional x64 - with Service Pack 1 My wireless adapter: Atheros AR9285 AdHoc 11n: Enabled The question - Does anyone have experienced the same problems as I do? Or does someone know how to solve this? Are there more tricks I can try, or settings I should change? Note - Our laptops are not slow or old. My laptop is 1.5 years old, and the other laptop is just 5 months old. I know how to keep laptops clean and I'm pretty sure both laptops are not bloated with useless software.

  • How to get wireless working (properly) with Sitecom Wireless USB micro adapter 300N on Windows 7?

    - by Timo
    The question says it all, but more detail follows ;) I've got a new computer that runs Windows 7 64-bits (Home Edition) and I'd like to connect it to my wireless home network (Sitecom wireless gigabit router 300N wl-352 v1 002) with a Sitecom wireless USB micro adaptapter 300 wl-352 V2 001. After installing the router (i.e. connected to the modem and power) and ensuring that wireless is indeed enabled, I've installed the driver of the USB adapter on the new computer described above. After the installation (drivers and utility on CD) completes successfull I rebooted my computer and inserted the USB adapter. After discovering the right network and connecting to it using the network key, a connection is succesfully made. (Using the Sitecom 300N USB Wireless LAN utility). In the LAN utility I can see that the signal strength is approximately 50% and connection quality is approximately 80%. Judging from these numbers I assumed that all was fine and started to use the connection (reading news on nu.nl, a dutch news site), but noticed that the connection was lost several times in a very short time span, but each time the connections was resumed, resulting in the 50/80 percent numbers described above. However, the website was not loaded completely and often a timeout would be reported. When inspecting the drivers through Device Management (Windows' Apparaatbeheer in dutch) there were no errors/warnings; everything seemed to be in order. In an attempt to solve this, I downloaded the latest drivers for the USB adapter, but the problems remained. Finally I tried to connect the computer with a Siemens Gigaset USB Adapter 108. This process was a troublesome since I had to download a driver (from the site above) and tell Windows (7) to use the Windows Vista driver when installing the new hardware, since there is (was) no Windows 7 driver available. This resulted in a usable connection, although not very stable when reconfiguring the router. Which took the form of selecting a different wireless channel on the router, even using the Sitecom utility mentioned above to check if there were other networks communicating on that channel (and thus picking a channel that was not used by other networks). Again no result when changing back to the Sitecom USB adapter. Note that this means (I think) that I could use the internet connection with the Siemens adapter, meaning the problem was not in the router. So: How to get wireless working (properly) with Sitecom Wireless USB micro adapter 300N on Windows 7? PS Sorry, but should be able to post one link, while I had links in place for the USB adapter, router and the siemens adapter in place as well, but I'm not (yet) allowed to post these... (The site says I can post one link, but only when no links are present will it allow me to post the question...)

  • How come transparency in textures appears as white in 3ds Max?

    - by rFactor
    I have downloaded a free tree palm model that came with textures and a preview image. In the preview image the tree looks fine, but when I have deployed the textures to my scene, the leaves look green plus white, where white is the transparency area. Is there something I need to know about transparent textures? Both in the view-port and in the renderer all transparency appears as white. What could it be? Edit: The model I was talking about is implemented with two JPGs. One is textured and the other one is black-white where white represents transparency and is applied to the material in the opacity channel/map. The transparency seems to work somewhat, but there are white borders around the leaves. I think it's because the opacity channel does not properly filter out all white colors for some reason. It also seems that changing the blur affects it, but setting it to 0 does not remove it though (and makes it jaggy).

  • IRC Services with failover support?

    - by insertjokehere
    I run a single server (call it 'server A') IRC 'network', and thank to the generosity of some friends, I have been given a second server ('server B') that I can run an IRCd on in order to provide redundancy in case server A crashes. This is fine, I can set up a round-robin DNS with the servers linked. The problem I have is what to do about services? Does anyone know of a way to get the services to 'fail over' in case of a server failure? Eg, Server A starts off running the services, but suddenly crashes. Server B detects this and starts its own copy of the services (ideally with the same configuration and data as the services on Server B) One solution that comes it mind is to write a bot that each server runs, that sit in a channel periodically checking if the bot from the other server is in the channel. If it is, then all is well. If not, then failover. I would prefer not to have to code this myself though We are currently using Unreal IRCd and Anope services on Linux

  • How do I record sound from my CD/DVD player without other system sounds in the mix?

    - by Software Monkey
    Using GoldWave I can record via the "Stereo Mix" channel, but I get no sound on the "CD" channel. Of course, using the stereo mix also mixes in all system sounds, including beeps, etc. I have the analog out on the DVD player connected to the CD-IN connector on the MoBo. I can hear CDs and DVDs playing just fine through my speakers - is this because the CD is also IDE data connection in to deliver the sound to the sound card, then? I specifically want to record a DVD; I can easily rip a CD using GoldWave's built-in ripper. Is there anything I have forgotten or have to enable? Or is it likely I have a damaged cable? My system is an MSI mobo and is running Windows XP SP3.
