• Alfresco Community Edition Consultants

  - by Talkincat

  I am in the process of putting together an document management system based on Alfresco Community 3.2r2. Because Alfresco will not allow its partners to work with the Community edition, I have found it devilishly tricky to find consultants that specialize in Alfresco to help me with this project. Can anyone point me in the direction of someone that can help me get this system up an running? I will mostly need help with integrating Alfresco with Active Directory (LDAP passthrough, user/group sync and SSO) and performance tuning the system. Any help is greatly appreciated.

• Online backup solution

  - by Petah

  I am looking for a backup solution to backup all my data (about 3-4TB). I have look at many services out there, such as: http://www.backblaze.com/ http://www.crashplan.com/ Those services look very good, and a reasonable price. But I am worried about them because of incidents like this: http://jeffreydonenfeld.com/blog/2011/12/crashplan-online-backup-lost-my-entire-backup-archive/ I am wondering if there is any online back solution that offers a service level agreement (SLA) with compensation for data loss at a reasonable price (under $30 per month). Or is there a good solution that offers a high enough level of redundancy to mitigate the risk? Required: Offsite backup to prevent data loss in terms of fire/theft. Redundancy to protect the backup from corruption. A reasonable cost (< $30 per month). A SLA in case the service provider faults on its agreements.

• Does my motherboard support dual-core processors?

  - by Filip

  Hi there! I'm very confused about my motherboard (ConRoe945PL-GLAN) It's manual says, that i can use only some kind of ConRoe processors. But some pages on internet says that i can plug in almost everything. For ex.: aria.co.uk says that i can plug in even Core 2 Duo. It would be awesome if i would not have to buy new motherboard! Anyway, if my motherboard will not let me to plug in Core 2 Duo, should i buy Pentium 4 (very cheap) with 3,2 GHz and insanely overclock it to have some performance or buy new motherboard + new processor for big money? THX for any answers! =)

• What does the number after 7-zip's -m switch mean?

  - by AndreKR

  7-zip has a command line switch to set the compression method, -m followed by a number, e.g. -m0=LZMA. What does the number (0 in the example) mean? Different numbers produce slightly different compression results and performance: time 7z -m0=LZMA -mx=9 -ms=on -mmt=off real 0m2.292s user 0m2.190s sys 0m0.080s time 7z -m1=LZMA -mx=9 -ms=on -mmt=off real 0m2.405s user 0m3.240s sys 0m0.070s time 7z -m0=LZMA -mx=9 -ms=on -mmt=on real 0m1.038s user 0m1.920s sys 0m0.150s time 7z -m1=LZMA -mx=9 -ms=on -mmt=on real 0m1.187s user 0m2.800s sys 0m0.130s

• Options to optimize lotus notes 8.5.X

  - by Jakub

  Has anyone found actually useful optimization methods for the bulky, fat, eclipse giant, nuissance that is Lotus Notes 8.5? I want it to be fast, and not eat up system resources like crazy while I run it ALL day (as it is my company's corporate mail / cal / scheduling solution). I've tried various hacks for the JVM heap size (if I recall correctly). None really bring a performance improvement. I have a dual core cpu, if that helps (I tried going the route of optimizing JAVA for 2 cores in hopes it would work, but seen no speed improvement). Notes is just sooo bloated, anyone have any suggestions to optimize/mod this thing so it is more responsive and less of a resource hog. Note: I don't want to switch to the web version, or the standard stripped down versions, I am aware of those, I just cannot since we don't run those internally for the company.

• Where should I go to learn about networking? [closed]

  - by Ollie Saunders

  I wonder if anyone could recommend resource or resources such as a good book that: explains how all the important protocols work and interact. I’m interested in those that are relevant in a typical home network and used over the Internet explains in detail how ADSL Internet connections work to the level of depth necessary so that I’m able to tweak and measure performance settings starts from the beginning but attempts to provide proper understanding rather than idiot-oriented steps to follow Basically, I’m interested in how these technologies work and tend to be implemented in hardware and software rather than “here’s what to do if…” I’m interested in Computer Networking by Andrew S. Tanenbaum and I wonder if anyone else has any experience with that title. It’s expensive but I could probably loan a copy for £3 from the library or so.

• Is an Ethernet point to point connection without a switch real time capable?

  - by funksoulbrother

  In automation and control, it is commonly stated that ethernet can't be used as a bus because it is not real time capable due to packet collisions. If important control packets collide, they often can't keep the hard real time conditions needed for control. But what if I have a single point to point connection with Ethernet, no switch in between? To be more precise, I have an FPGA board with a giga-Ethernet port that is connected directly to my control PC. I think the benefits of giga Ethernet over CAN or USB for a p2p connection are huge, especially for high sampling rates and lots of data generation on the FPGA board. Am I correct that with a point to point connection there can't be any packet collisions and therefore a real time environment is given even with ethernet? Thanks in advance! ~fsb

• Route gameserver traffic through cloudflare?

  - by Michael

  I use cloudflare for my website and we have a gameserver I was wondering if it is possible to route traffic through cloudflare. This recently sprung into my head when I realized that I could route Shoutcast through another of cloudflares port (8080) which does not do any performance enhancing or anything it just acts as a reverse proxy and stops DDoS. I then tried by setting up a subdomain with my gameserver IP cloudflared and then pinged the IP and Port. It seems to have connections but when actually connecting via the game it doesnt. Any ideas?

• MS SQL Server and "No Hard Drive Space Left"

  - by bobber205

  Got a server running a document delivery system on it. The machine is running extremely poorly (Windows XP). I've checked the regular things, like doing a memtest (turned out fine) and trying to degraf the HDD (not needed). The only thing weird about this machine is that its running MSSQL server. And Symantec Anitvirus. (ugh) Sometimes the machine reports "No hard drive space left". I immediately look at the one hard drive at the machine and it still has 20 gigs left. Each and every time. Could MSSQL server cause this? Could this be tied to the machine's terrible performance? Thanks!

• MaxClients in apache. How to know the size of my proccess?

  - by Larry

  From http://httpd.apache.org/docs/2.2/misc/perf-tuning.html The single biggest hardware issue affecting webserver performance is RAM. A webserver should never ever have to swap, as swapping increases the latency of each request beyond a point that users consider "fast enough". This causes users to hit stop and reload, further increasing the load. You can, and should, control the MaxClients setting so that your server does not spawn so many children it starts swapping. This procedure for doing this is simple: determine the size of your average Apache process, by looking at your process list via a tool such as top, and divide this into your total available memory, leaving some room for other processes. The main issue is that I can't understand how to know the size, because, well i have the size of httpd on no more of 3888 But, if we need to determine the number for MaxClients, and I have 4GB of RAM, so I get: 972, so I should use like 900 in the MaxClients?

• VMware networking - PortChannel or not?

  - by dunxd

  My ESX hosts each have 8 NICS. I have set up 2 NICs for our iSCSI SAN - each is connected to a different SAN switch. 2 NICs are set up for vMotion and Service Console - these are each connected to a different core switch (ports are trunked with VLANs dedicated to vMotion and Management) I now have four ports left over. Currently we have these set up each going into our default VLAN. Two NICs are connected to one core-switch and two are connected to the other. We decided to aggregate the connections to each switch - so they are teamed at the vswitch end, and port channelled at the physical switch end. I am now reading that port channelling these connections is not particularly useful, perhaps even over complicating things. Is there a particular problem with using port channels for VMware? What method provides the best balance between redundancy and performance?

• How well will ntpd work when the latency is highly variable?

  - by JP Anderson

  I have an application where we are using some non-standard networking equipment (cannot be changed) that goes into a dormant state between traffic bursts. The network latency is very high for the first packet since it's essentially waking the system, waiting for it to reconnect, and then making the first round-trip. Subsequent messages (provided they are within the next minute or so) are much faster, but still highly-latent. A typical set of pings will look like 2500ms, 900ms, 880ms, 885ms, 900ms, 890ms, etc. Given that NTP uses several round trips before computing the offset, how well can I expect ntpd to work over this kind of link? Will the initially slow first round trip be ignored based on the much different (and faster) following messages to/from the ntp server? Thanks and Regards.

• Mono on Linux: Apache or Nginx

  - by Furism

  Hi, I'm developing an ASP.NET application that will be run under Linux/Mono for various reasons (mostly to stay away from IIS, quite frankly). Of course the first web server I had in mind was Apache. But Apache, for all its advantages, adds a lot of overhead. Also, the application I'm building needs to be highly scalable and performance is one of the main concern. Apache has, obviously, a very good reputation and its record speaks for itself, but I don't need things like Reverse Proxy or Load Balancing because dedicated network devices would be used for that. So those modules from Apache will never be used. So basically my question is: since Nginx seems to fit exactly needs, is there any caveat I should be aware of? For instance, is Nginx renowned to be particularity safe? When security flaws are detected, how fast are they patched? Any insight on the pros and cons of using either of those servers in conjunction with Mono is welcome.

• Laptop wakes from sleep, once, due to audio controller (Windows 7)

  - by stijn

  The laptop is a recent Dell XPS 15z and the problem is as follows (reproducible about 90% of tries): put laptop to sleep using either Start-Sleep or closing the lid laptop goes to sleep after about 5 seconds, but instantly wakes again showing a black screen (touching the keyboard or moving the mouse shows the login screen one normally gets after wake) login again, put laptop to sleep latop stays in sleep mode output of powercfg -lastwake after the first instant wake shows the audio controller is responsible. Why would that be, why only the first try, and how to fix this?

• Blue Screen Of Death after Graphics Card Update

  - by John Smith

  I recently installed the game watch dogs After installing it i upgraded the drivers on my graphics card AMD Radion R9 200 series via the catalyst software and since then windows has been crashing on an ad-hoc basis even when sitting idle I have recieved two different sets of errors OXOOOOOOO1 and VIDEO_SCHEDULER_INTERNAL_ERROR I am running windows 8.1 with the driver 14.4 from AMD My PC shouldnt really be having this problem as it is pretty high spec due to my work Any help would be greatly appreciated as it is driving me up the walls a bit [UPDATE 08-06-2014] I have been looking around online and have crashed the PC a few times now trying to recreate the bug I have looked into the event history viewer and gotten the following errors amdacpusrsvc acpusrsvc: IOCTL_ACPKSD_KSD_TO_USR_SVC_SET_FB_APERTURES: FAILED acpusrsvc: GfxMemServiceInitialize: FAILED amdacpusrsvc acpusrsvc: IOCTL_ACPKSD_KSD_TO_USR_SVC_SET_FB_APERTURES: FAILED amdacpusrsvc acpusrsvc: GfxMemServiceInitialize: FAILED I took some advice from the AMD forums to re-install the old drivers to see if they would work. I uninstalled the old ones first and installed directly from the CD I got the warnings below but the driver installed "successfully" The Warnings are amdacpusrsvc acpusrsvc: ConfigureFrameBufferMemory: FAILED. Hopefully this will spark something off for someone Thanks John

• Samsung 830 very slow benchmark numbers

  - by alekop

  I just bought a new SSD, and installed a fresh copy of Windows on it. I didn't see any noticeable difference in boot times, app start-up times, so I decided to benchmark it. Asus P7P55D-E Intel i5-760 Samsung 830 256GB SATA III Windows 7 Ultimate 64-bit The Windows experience index gave the drive a 7.3 rating, but real-world performance is not particularly impressive. Any ideas why the numbers are so low? UPDATE: It turns out that SATA III support is turned off by default on the P7P55D motherboard. After enabling it in BIOS (Tools - Level Up), the scores went up: Read Write Seq 325 183 4K 16 49 IOPS 32K 28K It's an improvement, but still far below what they should be for this drive.

• Where does apache store initialization state for mod_proxy_balancer

  - by khoxsey

  I run apache2 on Ubuntu as a caching load-balancing reverse proxy in front of a group of application servers. I have noticed that the balancer maintains some state for some of the attributes visible in /balancer-manager such as whether an IP is enabled/disabled, load factor, etc. My site has periods of high (and low) usage, and recently as I added a new server to the working group I noticed that the load balancer picked up the new server but had it set to Disabled. I'm curious where that data is stored, and/or how it is initialized.

• Instant database snapshot

  - by raj

  My product uses oracle 9 database in its backend. every week the new release of the product is launched which will want to fire some DML, DDL queries to the database. I usually test the product release in a dummy database before applying it in the main database. I create a database dump using exp command, then import them into dummy database using imp. then i test the product in the dummy database and checks if there are any errors. This exp and imp takes about 3 hours to complete. Is there any alternative as : instant snapshot of the live database (which will be independent of the live one)? or is there any option to keep dummydatabase in sync with the originl database always. Yhis can be done by making the product firing DML&DDL queries to both the databases.. but this will be a HUGE performance problem.. how can i overcome this?

• What's the point of Netgear's WNHDB3004 "3DHD WIRELESS HOME THEATER NETWORKING KIT"

  - by badp

  Here's a crude representation of what I've got at home: floor 2 INTERNETS ---- MODEM/ROUTER ---- MY COMPUTER | floor 1 WIFI REPEATER ---- stuff | floor 0 more stuff TELEVISION Now, as part of our sat tv subscription we can get an additional service if we connect our decoder (located by TELEVISION obviously) to the internet. What they suggest is buying a Netgear 3DHD WIRELESS HOME THEATER NETWORKING KIT holy shit isn't my bullshit-o-meter flying high right now from the general buzzwordyness of this thing. What does this thing actually do that our existing wireless-enabled routers don't do? What's the point of having a third wifi router in the same house, this time only for one television? If I do decide to plunge €99 for this, should I connect it to the wifi repeater (which does not provide AAA quality internet, at least for all gaming purposes) or to my modem/router (risking issues with low signal?).

• How does ARM Cortex A8 compare with a modern x86 processor

  - by thomasrutter

  I was wondering how does a modern ARM chip based on ARM Cortex A8 compare, in clock-for-clock performance and capability, to a modern x86 chip such as a Core 2 Duo or Core i5? I realise due to the different instruction sets it'll depend heavily on what you're doing. To put it another way, rendering a web page in webkit on a 1GHz ARM Cortex A8 based chip should be about equivalent to doing in on a Core i5 at __ MHz? Update October 2013: Since I asked this question years ago it's become a lot more common, when reading about mobile devices, to see architecture-agnostic benchmarks that you can compare across platforms - for example, in-browser benchmarks like Sunspider in Webkit will run on just about anything and you see these in reviews all the time now. And there's things like Geekbench now.

• NFS failover WITHOUT DRBD?

  - by user439407

  So I am trying to set up a redundant NFS share in a cloud environment(all links internal, half gig links), and I am looking into using heartbeat for failover, but all the guides seem to be about combining DRBD and heartbeat to create a robust environment. If need be I can do that, but since my content is almost completely static, I would like to avoid the extra overhead and complexity of DRBD if possible, but still be able to fail over if one of the NFS servers fails. Is it possible to use heartbeat with NFS to achieve high-availability without using DRBD to copy the blocks? I am not married to NFSv4, so if NFSv3 over UDP is necessary, that won't be a problem(only a very small number of clients will be connecting to the share) Any comments are appreciated.

• How to unmount a VHD in Windows 7. There is no unmount option.

  - by Triynko

  I mounted a VHD file in Windows 7 using the Disk Manager. Once mounted, there is no option to Unmount it. The only thing close to such an option that I can find is if I click the icon in the taskbar notification area that I use to remove USB devices... there's an option to eject the virtual hard disk. However, when I click that, it says that it's in use and cannot be ejected. Even though... it's not in use, I never even browsed the drive. The disk manager is closed... and the only open files handles to the drive (according to disk performance in task manager) is SYSTEM. Ejecting devices cleanly has been a problem since Windows XP, and it sickens me to see it persist into windows 7.

• Freezing of computer while watching flash videos (contd)

  - by t3st

  I have asked this similar question Computer freezing while watching Flash videos from net two week before. As i mentioned in my previous problem my computer freezes while watching online videos showing 100% cpu usage. I have tried the suggestions given in that query and I have formated my whole computer and installed windows and other softwares (with latest updates) but the problem still presisting. If i watch a video online approximately after one hour my system shows very high cpu usage and when i close my browser cpu usage comes to normal(i tried to watch Cybergeddon but my computer is freezing from start,and also other youtube videos). Can you tell me whether its an hardware problem? if yes can you give any possible explanation( eg:motherboard problem,over heating etc) because i want to tell those reasons to my computer mechanic.

• Task bar remains visible with "Auto-hide the task bar" checked in Windows 7.

  - by Corey

  It's about time that I figure this out. I can say with a pretty high confidence that I have experienced this issue in all consumer versions of Windows since XP. I keep "Auto-hide the task bar" checked to maximize screen real estate. Every once in a while, the task bar will refuse to hide while individual windows will continue to act as if that option is checked (by falling under the task bar). For years, I have fixed this by rebooting. Of course, I cannot predict the timing or frequency of the problem, so the process becomes burdensome. I want to know how this can be fixed without rebooting. It has affected my on multiple machines using multiple versions of Windows, so I cannot be the only one who is bothered by it. Can anyone help me solve this?
