  • Achieving AES-256 Channel Encryption with the .NET Compact Framework

    - by Ev
    Hi There, I am working on a business application where the clients are Windows Mobile 6.1 Professional devices. The server is a Java enterprise application. The industry working group recommends AES-256 encryption for client/server communications. This is necessary to gain certification. The encryption doesn't necessarily need to be channel encryption, it could be payload encryption. Channel encryption is preferable. The client and server communicate using SOAP/HTTP, which we are yet to implement. We plan to use WCF on the compact framework. In order to alleviate some of the work required to implement manual encryption/decryption, it would be nice if we could achieve the required encryption either at the TLS level, or somehow using the WS-* standards (I'm not particularly familiar with that group of technologies but I am learning right now). The server supports https with 256-bit AES. Does anybody have an idea on the best way to implement this? Thanks in advance.

  • Is a computer's DRAM size not as important once we get a Solid State Drive?

    - by Jian Lin
    I am thinking of getting a Dell X11 netbook, and it can go up to 8GB of DRAM, together with a 256GB Solid State Drive. So in that case, it can handle quite a bit of Virtual PC running Linux, and Win XP, etc. But is the 8GB of RAM not so important any more? Won't 2GB or 4GB be quite good if a Solid State Drive is used? I think the most worrying thing is that the memory is not enough and the less often used data is swapped to the pagefile on hard disk and it will become really slow, but with an SSD drive, the problem is a lot less of a concern? Is there a comparison as to, if DRAM speed is n, then SSD drive speed is how many n and hard disk speed is how many n just as a ball park comparison?

  • Does PCI bus really occupy 1.8GB

    - by Neil
    I am using a Dell Vostro 1700 laptop which currently has 2GB of RAM. I was considering buying some more memory to upgrade it to 4GB. I am running 32 bit Windows Vista and I know that there can be issues that prevent it from making use of a full 4GB which I believe relate to the fact that memory mapped devices, e.g. graphics card, also need to be allocated addresses in the 4GB range addressable with 32 bits. Consequently I was looking at device manager - resources by connection - memory to see what devices where allocated what memory addresses. I was surprised to see that there was an entry for [80000000 - F3FFFFFF] PCI bus. That is a 1.8GB range of addresses. When I expanded it the only thing in it was [E0000000 - EFFFFFFF] NVIDIA GeForce 8600M GT which is only 256MB. So my question is does the PCI bus really occupy 1.8GB of address space and will it prevent my computer from making use of any more memory than it already has.

  • Ram configuration 4x4 or 2x8?

    - by Carl B
    I am looking to upgrade my Ram to 16gigs and I am wondering if there is any distinct advantage of the way I do it. That being a 4x4 or 2x8 set up. In all my searching there have been a number of pros for each profile. I can find no benchmarck results for either setup as a compaison. So, if there are 2 profiles of the same speed, same voltage, same timing and same cas what would perform better or have a better over all benafit? A few examples from my search - a 4x4 set would lend a benafit in that if one stick failed, you only lose 25% of your Ram vs 50% in a 2x8 set up. a 2x8 set up would have less strain on the memory controler and motherboard. a 2x8 would generate less heat. a 2x8 set up is easier to over clock (not part of my need, but alot of the comparisons circled around the overclocability ease of the 2 stick set up). There is one outstanding benafit that I have found in at least the target company I have looked at and that is price. The 2x8 is nearly half the cost. My motherboard supports a max of 16 gigs and I have a 64 bit OS. Has anyone seen any performance comparisons or is 16 gb just 16 gb no matter how you slice it? And is there any merit to the above pros? Edit: as per the mobo specs - Main Memory • Supports four unbuffered DIMM of 1.5 Volt DDR3 800/1066/1333/1600*/1800*/2133* (OC) DRAM, 16GB Max

  • Why this button doesn't cause triple postback?

    - by focus
    We have developed a page with a asp.net and debugging it accidentally we have discovered on our page button with the next code on onclik attribute onclick="__doPostBack('ctl00$FormPlace$m_userTaskMarkAsUnreadButton',''); __doPostBack('ctl00$FormPlace$m_userTaskMarkAsUnreadButton','');WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$FormPlace$m_userTaskMarkAsUnreadButton", "", true, "", "", false, false))" It seems that the button do three postbacks but when we click it only cause on postback. With this code seems that de button will cause three postbacks!! We have try it with Internet Explorer and Firefox and the button only cause on postback always. Are browsers who avoid that the button do three postback ? Or Is Asp.net server who avoid the three postback? We don't understand why the button behaves correctly if onclick attribute has three call to do Postbacks. Thanks

  • Python what's the data structure for triple data

    - by Paul
    I've got a set of data that has three attributes, say A, B, and C, where A is kind of the index (i.e., A is used to look up the other two attributes.) What would be the best data structure for such data? I used two dictionaries, with A as the index of each. However, there's key errors when the query to the data doesn't match any instance of A.

  • Sound doesn't work anymore after replacing RAM

  • Recommendations for SSD for server and database use?

    - by Tony_Henrich
    SSDs are a new technology and they are constantly improving. A lot of the posts here were posted in 2009 when SSDs where less mature and not as fast. What was recommend back then is probably out of date today because of better options. The SSD is used to hold SQL Server databases. Size is probably 128G. The database is used with a CMS and web server so web pages need to get their data and render as fast as possible. Which modern SSD is recommended for such a use? Is there an SSD better than Intel X-25 E/M in terms of performance/cost? (I am also evaluating cost between : RAM + UPS (semi persistent) vs SSD for same amount of gigabytes. No RAID is involved)

  • Unusually high memory usage on a CentOS VPS with 512 guaranteed RAM

    - by Andrei Bârsan
    I'm working on a medium-sized web application written in PHP that's running on a VPS with 512mb ram. The webapp hasn't been officially launched yet, so there isn't too much traffic going on, just me and a few other people working on it. There is another slightly smaller webapp also hosted on this machine, among 4-5 other small static sites. We are running Centos 5 32-bit & cPanel/WHM. This is the result of running ps aux and, as you can see, it's not using 100% of the RAM. However, on the hypanel overview, it's always shown as using aroun 500MB ram, just for running apache, mysql, and the lowest-memory-footprint versions of the mail server, ftp server etc. -bash-3.2# ps aux USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.0 2156 664 ?

  • GA 8KNXP Rev1.0: 4 GB installed, only 3.5 GB recognized by BIOS

    - by hurikhan77
    I've installed 2x 1 GB and 4x 512 MB memory into my GA-8KNXP system which would sum up to 4 GB. The specification from the manual says: Maximum memory support: 4 GB. If all six slots are utilized, slot 5+6 may only equipped with single-sided RAM modules. And so I did. Anyway: The BIOS counts up to 3.5 GB and finishes there. Also my Linux system reports only 3.5 GB of memory although 4 GB memory support is activated in the kernel. So I suppose this is a memory mapping issue or a hardware issue. I've tried removing only on of the 512 MB memory modules leaving 5 modules in place. But that just stopped the system from powering on correctly (screen stays black although fans and leds come to live). Dual Channel was detected and enabled so the system technically found all 6 modules. "dmidecode" in Linux reports only memory in slots 1 to 4 and ignores slots 5+6, so it only detects 3 GB of memory. It also says the system would support up to 16 GB of memory with 4 GB modules per slot. I think technically the chipset should be able to offer and utilize the complete 4 GB memory range. Any clues what else I could check? Or do I have just to live with 0.5 GB wasted memory?

  • Any dangers in using DDR memory with a higher frequency than the FSB?

    - by raw_noob
    I'm looking to upgrade memory in an older motherboard. The processor is an AMD Sempron 2500+ with a maximum speed of 333/166MHz. The motherboard is an MSI MS-7061 (KV3M-V), which accepts up to 2Gb of DDR memory maximum PC2700 in 2 slots and has a maximum FSB of 333MHz. The board does not have dual-channel support. Existing memory includes a stick of 512Mb PC3200, which seems to be running OK (presumably at PC2700) but is rated 200MHz, which is below the FSB speed. The other stick is 256Mb PC2100/133MHz, again below the FSB speed. (All figures from CPU-Z.) I have a chance to acquire a single used stick of PC3200/400MHz memory very cheaply. Crucial's system scanner seems to suggest that this will be OK with my system, but other sites have suggested that running memory with a higher frequency than the FSB can cause instability. Is this true? Would I be better waiting until I can buy the correct PC2700/333MHz stick? I'm assuming that the mixed memory I have at present is running as 768Mb at 133MHz. Is this a reasonable assumption? If so, would you expect the performance differences between 768Mb/133MHz and 1Gb/333MHz to be very noticeable? If I install the new 1Gb/400 or 333MHz stick in slot 1, am I right in thinking that adding back the existing 512Mb/200MHz stick in slot 2 would pull the whole 1.5Gb system memory speed down to 200MHz? If so, which would be better - 1.5Gb/200MHz, or the single 1Gb stick at the full 333MHz that the FSB permits? Is more headroom more important than extra speed? Any help - or even opinions - gratefully received. I can't find reliable information, and I can't afford to make expensive mistakes.

  • FCoE, on any Ethernet switch?

    - by javano
    I understand the concept of FCoE. I have looked at the Wikipedia page and looking at the layer 2 frame diagram, it looks like FCoE really should "just work" on any Ethernet switch, but is this really the case? If so, what do switches like Cisco's Nexus 5k or 6120P offer that normal switches don't (in specific relation to FCoE)? I am just using those two switches as examples. On the Nexus 5548UP page for example it says the following; Unified ports that support traditional Ethernet, Fibre Channel (FC),and Fibre Channel over Ethernet (FCoE) Well if FCoE runnins over regular Ethernet, that why does it support "Ethernet and Fibire Channel over Ethernet"? This is why I am curious as to weather FCoE will run on any Ethernet switch and these switches just support "bonus" features, or if you do indeed require a specialist switch. Thank you.

  • Sun T5120: Memory issue with 8GB DIMMs, "Unsupported memory configuration"

    I'm trying to upgrade RAM in a Sun T5120 server, replacing 2GB (Sun P/N: 501-7953-01) with 8GB DIMMs (Sun P/N: 511-1262-01). When bringing up the host system, I get the following errors on the ILOM: -> show faulty Target | Property | Value --------------------+------------------------+--------------------------------- /SP/faultmgmt/0 | fru | /SYS/MB /SP/faultmgmt/0/ | timestamp | Dec 14 15:29:42 faults/0 | | /SP/faultmgmt/0/ | sp_detected_fault | /SYS/MB/CMP0/MCU3 Forced fail faults/0 | | (IBIST) /SP/faultmgmt/0/ | timestamp | Dec 14 15:29:28 faults/1 | | /SP/faultmgmt/0/ | sp_detected_fault | /SYS/MB/CMP0/MCU2 Forced fail faults/1 | | (IBIST) /SP/faultmgmt/0/ | timestamp | Dec 14 15:29:13 faults/2 | | /SP/faultmgmt/0/ | sp_detected_fault | /SYS/MB/CMP0/MCU1 Forced fail faults/2 | | (IBIST) /SP/faultmgmt/0/ | timestamp | Dec 14 15:28:59 faults/3 | | /SP/faultmgmt/0/ | sp_detected_fault | /SYS/MB/CMP0/MCU0 Forced fail faults/3 | | (IBIST) /SP/faultmgmt/1 | fru | /SYS /SP/faultmgmt/1/ | timestamp | Dec 14 15:29:42 faults/0 | | /SP/faultmgmt/1/ | sp_detected_fault | Dec 14 15:29:42 ERROR: faults/0 | | Unsupported memory | | configuration As you can see, the only error message I get is "Unsupported memory configuration".

  • How can I allocate 8 GB ( not 1 GB ) RAM to my JDK on windows

    - by Deepak
    JDK on Windows takes max around 2 GB RAM. Even if we allocate more RAM to our JDK; it doesnt take it. If I need to run a process which need 8 GB RAM on Windows; how can I achieve it ? Do we have any JDK provided by any other provider which could support it ? Memcached provides us additional cache which can be used... but that is not I am looking for. Suppose I need to run my jMeter with 8 GB RAM on my windows box; Memcached wont help for sure.. Is there any provider which provides me with this ? Previosly I thought Terracotta does that; but looks like that also is like Memcached. I am using Windows 7. If needed I can use Windows Server also.. I just need to get it running.

  • 32bit vs 64bit guest VM and RAM usage

    - by sims
    Why does a 32bit domU (Xen guest VM) use less RAM than a 64bit? Notes: The same software complied for a different arch(AMD64 vs. 686). Obviously this is Linux or BSD or something easily ported. Maybe this is also a good one for SO. I've read this is so. I can guess why, but I'd like to hear everyone's comments.

  • Which will give more free RAM to linux?

    - by Linda Thomas
    Trying to avoid some issues so I've been trying to learn vm. in kernel tuning but still a little confused even after googling. The lower background_ratio is the sooner the flushes? the lower dirty_ratio is the less dirty ram that is kept, right vm.dirty_ratio = 20 vm.dirty_background_ratio = 1 or vm.dirty_ratio = 60 vm.dirty_background_ratio = 20 or vm.dirty_ratio = 20 vm.dirty_background_ratio = 10 or vm.dirty_ratio = 20 vm.dirty_background_ratio = 5

  • PHP hits 100% CPU and eats RAM at the same time Monday to Friday

    - by Daniel Samuels
    We run a learning platform for primary schools here in the UK and it's all been running extremely well. However at around 4PM Monday to Friday we see the same issue arise -- 1-2 PHP threads will spike to 100% CPU and gradually start eating up RAM until the server(s) fall over. 98%+ of our requests are HTTPS, these come into our Layer 7 load balancer which then decrypts the SSL data, adds the X-HTTP-Forwarded-For header and forwards the data onto an application server (we have 2 of those at the moment) on port 80. Our application servers have Varnish on port 80 which takes in the request from the load balancer and passes the request through to Nginx on port 81. Nginx then works out which 'vhost' it needs to use and passes any PHP processing through to PHP-CGI which is listening on a socket (managed through spawn-fcgi). There's an instance of Memcached running too, MySQL runs on a separate server / slave setup. Throughout the day the load will typically go no higher than 0.8 on either of the application servers, however at around 4PM our problem arises. I've managed to run strace on a few of the actual threads when they cause the problem and I always see the same thing: stat("/usr/share/zoneinfo/Europe/London", {st_mode=S_IFREG|0644,st_size=3661, ...}) = 0 stat("/usr/share/zoneinfo/Europe/London", {st_mode=S_IFREG|0644,st_size=3661, ...}) = 0 This is repeated infinitely and never stops until you SEGKILL the process or oomkiller kills it. There are no cron jobs scheduled to run at that time and I don't have any way of seeing exactly what Nginx request is associated with the PHP process which is running. We are running PHP 5.3.14 which we upgraded to from 5.3.8 last week to rule out the older version being the problem. This issue has been going on a few months now and we have no idea what is causing it. We deploy our software very frequently, so it's difficult to track down a specific release which may have started the problem - especially as we do not know the date of the first occurrence of this issue. Varnish is version 3.0.1, Nginx is 1.0.6 (which I understand is about a year old now), our servers are running CentOS release 5.7 (Final) they have Intel i3 540s at 3.07Ghz and 8GB of RAM. There's a discussion on the Debian mailing list about something very similar, you can find that here. Has anyone seen anything like this in the past, does anyone have any ideas or suggestions? Are there a way of linking an Nginx request directly to a PHP thread? Is there a better way of seeing what the PHP process is doing? (I've seen GDB mentioned, though I'll have to recompile PHP) Thanks!

  • How cpu writes data to dynamic RAM

    - by Krit
    Hello, I would like to know what kind of electrical signals does a cpu send to a dynamic RAM when it wants to write one bit (a 1 or 0). Is it simply that cpu sends just a single electric pulse, and if that electric pulse's voltage is higher than a certain level, it charges the capacitor to a voltage level that is "1" and if it is at a lower voltage band, it charges capacitor to level that it is "0"?

  • Why is my computer using so much ram?

    - by Ian
    I have 16gb of ram installed in my computer, and nearly 70% of it is used at all times. Looking at the processes in task manager the memory being used with everything in there doesn't even add up to 2gb. I have RAPID mode enabled on my ssd which may be using 2gb at most so I would understand that. I am thinking there might be a memory leak somewhere, but I don't really know how I would be able to tell. My performance and process list is below:

  • Increase in Available Memory expected by adding 1Gb RAM to a 3Gb Vista 32 bit system

    - by Bob423
    I understand the 32 bit Vista limit in addressing only 4Gb of memory space but I have a very specific question: I have 3Gb installed on a Vista 32 bit system with a 512Mb video card, MSI X-58 board, Intel i7, 920 CPU. System Information currently shows: Installed Memory: 3.00Gb Available Physical Memory: 1.73 Gb My understanding is that the 512Mb video card occupies memory addresses between 4.0Gb and 3.5Gb and so does not subtract from the 3.0Gb of physical memory (correct my understanding if wrong) My Question: If I install another 1Gb of RAM, will my Available Memory increase to 2.73Gb? Thanks, Bob423
