sudoer scheme for another web developer that retains my future control of a virtual server?

- by Tchalvak

Background: Virtual Private Server I have a virtual private server that I'm looking to host multiple websites on, and provide access to another web developer. I don't care about putting too many constraints on him, though I wouldn't mind isolating the site that he'll be developing from other sites on the server that I will develop. The problem: retain control Mainly what I want is to make sure that I retain control over the server in the future. I want to reserve the ability to create/promote/demote and other administrative functions that don't deal with web software. If I make him an admin, he can sudo su - and become root and remove root control from me, for example. I need him not to be able to: take away other admin permissions change the root password have control over other security/administrative functions I would like him to still be able to: install software (through apt-get) restart apache access mysql configure mysql/apache reboot edit web development configuration type files in /etc/ Other Standard Setups would be happily considered I've never really set up a good sudoers file, so simple example setups would be very useful, even if they're only somewhat similar to the settings that I'm hoping for above. Edit: I have not yet finalized permissions, standard, useful sudo setups are certainly an option, the lists above are more what I'm hoping I can do, I don't know that that setup can be done.

I'm sure that people have solved this type of problem before somehow, though, and I'd like to go with something somewhat tested as opposed to something I've homegrown.

Why i disconnect every few seconds? using USB wireless adapter

- by Rev3rse

i know it's for ubuntu questions..but mint and ubuntu are very similiar and i had the same problem with linux ubuntu too..so i think this is the right place for my question anyway i don't have experience with drivers and other things,after installing Linux on my machine( i did dist-upgrade btw) everything seem to be great because i didn't have to install any driver, after a while i realized that my connection stop after few minutes(actually it shows that I'm connected but it's not) so i have to reconnect and after few minutes it disconnect again. I'm using Alfa USB wireless adapter AWS036H, and my Linux version is 11 i think the driver i'm using is Realtek i searched in the Internet and i found nothing. these are some outputs of few things people usually ask for: Note: I'm NOT using a laptop. dmsg: [19445.604448] [UFW BLOCK] IN=wlan0 OUT= MAC=00:c0:ca:44:62:d1:00:24:c8:4b:46:e0:08:00 SRC=2.174.220.77 DST=192.168.1.6 LEN=52 TOS=0x00

The SPECjEnterprise2010 benchmark has been designed and developed to cover the Java EE 5 specification's significantly expanded and simplified programming model, highlighting the major features used by developers in the industry today. This provides a real world workload driving the Application Server's implementation of the Java EE specification to its maximum potential and allowing maximum stressing of the underlying hardware and software systems. The workload consists of an end to end web based order processing domain, an RMI and Web Services driven manufacturing domain and a supply chain model utilizing document based Web Services. The application is a collection of Java classes, Java Servlets, Java Server Pages, Enterprise Java Beans, Java Persistence Entities (pojo's) and Message Driven Beans. The SPECjEnterprise2010 benchmark heavily exercises all parts of the underlying infrastructure that make up the application environment, including hardware, JVM software, database software, JDBC drivers, and the system network. The primary metric of the SPECjEnterprise2010 benchmark is jEnterprise Operations Per Second ("SPECjEnterprise2010 EjOPS"). This metric is calculated by adding the metrics of the Dealership Management Application in the Dealer Domain and the Manufacturing Application in the Manufacturing Domain. There is no price/performance metric in this benchmark. Key Points and Best Practices Sixteen Oracle WebLogic server instances were started using numactl, binding 2 instances per chip. Eight Oracle database listener processes were started, binding 2 instances per chip using taskset. Additional tuning information is in the report at http://spec.org.

Can the Intel C600-series SAS controller RAID SATA drives?

- by CyberShadow

(Sorry if this is off-topic - technically this is a home workstation setting, but is regarding mostly-server technology.) I have a GA-X79S-UP5-WIFI motherboard and four ST3000DM001 drives, and the IRST manager isn't letting me put the drives in a RAID (it lists them, but the option to select the C600-series controller is simply grayed out). Have I done a mistake? Do I need SAS drives to RAID them on the SAS controller?

PC to USB transfer slow

- by Vipin Ms

I'm having trouble with USB transfer,not with external hard disk. Transfer starts with like, for the transfer of 700MB file it starts with 30mb/s and towards the end it stops at 0s and stays put for like 3-4 mins to transfer the last bit. I have tried different USB devices, but no luck. Is it a bug? Another important point is, in Kubuntu there is no such issue. So is it something related to Gnome? I'm using Ubuntu 11.10 64bit. Somebody please help, it's really annoying. Here are the details. PC all of my drives are in ext4. USB I tried ext3,ntfs and fat32. All having the same problem.

Hi guys I'm a web designer and front end developer, however our only back end developer has quit and left the company. The head of development(who is a desktop developer) has asked me to find a set of Questions and Answers that are of OOP level for a LAMP developer so we can see if new candidates for the job are up to scratch. As a designer I'm out of my depth and he's unfamiliar with LAMP development. Dan

Buyers question: Have intel AES-NI already been integrated in IPSEC stacks?

- by deploymonkey

Dear serverfault, I need to decide between deploying Opteron 6100 and Xeon Westmere EP, so I regard this a platform question. If not, it may be moved to stackoverflow and I hereby declare that I am very sorry. Do any (F)OSS or proprietory IPSEC stacks already use the AES-NI functions of the Westmere-EP? Thanks a bundle! ps. If anyone would like to create the tag AES-NI, You're welcome. I couldn't due to lack of rep.

Thoughts on schemas and schema proliferation

- by jamiet

In SQL Server 2005 Microsoft introduced user-schema separation and since then I have seen the use of schemas increase; whereas before I would typically see databases where all objects were in the [dbo] schema I now see databases that have multiple schemas, a database I saw recently had 31 (thirty one) of them. I can’t help but wonder whether this is a good thing or not – clearly 31 is an extreme case but I question whether multiple schemas create more problems than they solve? I have been involved in many discussions that go something like this: Developer #1> “I have a new function to add to the database and I’m not sure which schema to put it in” Developer #2> “What does it do?” Developer #1> “It provides data to a report in Reporting Services” Developer #2> “Ok, so put it in the [reports] schema” Developer #1> “Well I could, but the data will only be used by our Financial reporting folks so shouldn’t I put it in the [financial] schema?” Developer #2> “Maybe, yes” Developer #1> “Mind you, the data is supposed to be used for regulatory reporting to the FSA, should I put it in [regulatory]?” Developer #2> “Err….” You get the idea!!! The more schemas that exist in your database then the more chance that their supposed usages will overlap. I’m left wondering whether the use of schemas is actually necessary. I don’t view really see them as an aid to security because I generally believe that principles should be assigned permissions on objects as-needed on a case-by-case basis (and I have a stock SQL query that deciphers them all for me) so why bother using them at all? I can envisage a use where a database is used to house objects pertaining to many different business functions (which, in itself, is an ambiguous term) and in that circumstance perhaps a schema per business function would be appropriate; hence of late I have been loosely following this edict: If some objects in a database could be moved en masse to another database without the need to remove any foreign key constraints then those objects could legitimately exist in a dedicated schema. I am interested to know what other people’s thoughts are on this. If you would like to share then please do so in the comments. @Jamiet

Bad Intel DQ965GF motherboard? Fails memtest, but memory is good.

- by Boden

I've got a machine with a DQ965GF motherboard. Two days ago it started locking up hard. Ran memtest 3.3, 1.7, and TestMem 4. TestMem just freezes, memtest failed on moving 8 bit inversions. Letting memtest run eventually causes the system to restart. I pulled memory sticks one by one, and then replaced the memory with a couple of known good sticks. No luck. I switched power supplies, didn't help. Swapped video cards just to be safe. No help. When I start the machine I get a single beep before it POSTs. According to the manual, a single beep means: 1 beep - Refresh Error (with nothing on the screen and it is not a video problem) I'm assuming that the motherboard has failed since it's obviously not a RAM or power issue. Do you agree? NOTE: I also tried resetting BIOS defaults, and even flashed the BIOS to the latest version. I also ran the Mersenne Prime Test and the CPU seems to click along just fine. (Tried logging in to superuser with openid but it's not working for me today. Hope this gets through)

Duplicate GET request from multiple IPs - can anyone explain this?

- by dwq

We've seen a pattern in our webserver access logs which we're having problem explaining. A GET request appears in the access log which is a legitimate, but private, url as part of normal e-commerce website use (by private, we mean there is a unique key in a url form variable generated specifically for that customer session). Then a few seconds later we get hit with an identical request maybe 10-15 times within the space of a second. The duplicate requests are all from different IP addresses. The UserAgent for the duplicates are all the same (but different from the original request). The reverse DNS lookup on the IPs for all the duplicates requests resolve to the same large hosting company. Can anyone think of a scenario what would explain this? EDIT 1 Here's an example that's probably anonymised beyond being any actual use, but it might give an idea of the sort of pattern we're seeing (it's from a search query as they sometimes get duplicated too): xx.xx.xx.xx - - [21/Jun/2013:21:42:57 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "http://www.ourdomain.com/index.html" "Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0)" xx.xx.xx.xx - - [21/Jun/2013:21:43:03 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:03 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" xx.xx.xx.xx - - [21/Jun/2013:21:43:04 +0100] "GET /search.html?search=widget&Submit=Search HTTP/1.0" 200 5475 "" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.91 Safari/534.30" UPDATE 2 Sometimes it is part of a checkout flow that's duplicated to I'd think twitter is unlikely.

Intel PRO/1000 Server NIC on Windows latency. How to measure?

- by Bobb

Please note - this question is about latency of the card itself. Not latency of internet or anything else. Thank you for your attention on this matter. It is often said that good server NIC does make difference compared to low grade cards and on-board Ethernet chips. I understand that on-board chip will likely consume CPU time and stand-alone card would use its own chip. Also server card would be faster than low-grade card. Are these 2 facts explaining most of the server cards advantages over on-board and low-grade cards ethernet? How would you measure latency on the card itself? I saw some reports stating some microseconds figures of NIC latency but I dont see how to measure that... Any advise will be appreciated.

Are two periods allowed in the local-part of an email address?

- by Mike B

A third-party email gateway relay is refusing to process a message for an email address we're sending to. The address is in the format of [email protected] (note the two periods). Is this allowed by RFC guidelines? RFC 2822 seems to object to this in section 3.4.1: The locally interpreted string is either a quoted-string or a dot-atom. If the string can be represented as a dot-atom (that is, it contains no characters other than atext characters or "." surrounded by atext characters), then the dot-atom form SHOULD be used and the quoted-string form SHOULD NOT be used. Comments and folding white space SHOULD NOT be used around the "@" in the addr-spec. Furthermore, in that same section, it references this: addr-spec = local-part "@" domain local-part = dot-atom / quoted-string / obs-local-part I interpret this to mean that the localpart can have content separated by dots but there cannot be two successive dots, and it cannot start or end with a dot. That being said, I'm not familiar with dot-atom syntax so maybe I'm mistaken here. Can someone please confirm and explain?

How can one create a bootable linux usb key that works on Mac (Intel 64 bit CPU) hardware ?

- by user3621

Hi, I'm trying to create a bootable usb key with linux (debian) and that can be booted on Macintel hardware. I have read that MAC's EFI can only boot GPT GUID formatted disks. I'm desperately trying to find a good tutorial which explains how to create such a key. Here what I have done so far: create a GUID partition on te key using linux GNU parted create a HFS+ or ext3 partition on the key, with the boot flag on install a linux .iso with unetbootin While all steps were successfull and in some cases I could even boot on a PC, the step of booting on Macintel software failed (on a macbook). I need to precise that I holded the "alt" key while booting the mac and the only visible bootable disk was the hard disk. Thanks for any advice. PS: I have tried with rEFIt as well. In one case I had a "windows" icon but it then failed to boot with a message like "no system found"

Why would the IE Developer Toolbar claim a style is applied, yet that supposed fact is not reflected

- by Deane

I have a situation where IE7 is simply not applying styles, even though it claims it is. I have an element on my page. In the CSS, I have defined a rule that should apply "display: none" to it, so it should not be displayed. It's still displaying. I downloaded the IE Developer Toolbar, and found the element in the DOM selector. I right-clicked and selected "Applied Styles." Right there, IE claims that it is applying my "display: none" rule. In fact, the "Applied Styles" dialog confirms everything I think I know about my CSS and how it should be applied. Yet the element remains. Now, I'm not asking anyone to debug my CSS here. I'm asking, if the IE Developer Toolbar claims/confirms this element should be gone, but it's still there...what does that mean, exactly? Since the Toolbar is on my side, I think my CSS is fine. Is there some IE7 bug I'm not considering? Edit: One thing that might be relevant: the LINK elements that load the stylesheets are applied to the page in Javascript, via "document.write". I'm starting to suspect that has something to do with it.

What is the recommended way of parsing an XML feed with multiple namespaces with ActionScript 3.0?

Method 1: protected function xmlResponseHandler(event:ResultEvent):void { var atom:Namespace = new Namespace("http://www.w3.org/2005/Atom"); var microsoftData:Namespace = new Namespace("http://schemas.microsoft.com/ado/2007/08/dataservices"); var microsoftMetadata:Namespace = new Namespace("http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"); var ac:ArrayCollection = new ArrayCollection(); var keyValuePairs:KeyValuePair; var propertyList:XMLList = (event.result as XML)..atom::entry.atom::content.microsoftMetadata::properties; for each (var properties:XML in propertyList) { keyValuePairs = new KeyValuePair(properties.microsoftData::FieldLocation, properties.microsoftData::Locationid); ac.addItem(keyValuePairs); } cb.dataProvider = ac; } Method 2: protected function xmlResponseHandler(event:ResultEvent):void { namespace atom = "http://www.w3.org/2005/Atom"; namespace d = "http://schemas.microsoft.com/ado/2007/08/dataservices"; namespace m = "http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"; use namespace d; use namespace m; use namespace atom; var ac:ArrayCollection = new ArrayCollection(); var keyValuePairs:KeyValuePair; var propertyList:XMLList = (event.result as XML)..entry.content.properties; for each (var properties:XML in propertyList) { keyValuePairs = new KeyValuePair(properties.FieldLocation, properties.Locationid); ac.addItem(keyValuePairs); } cb.dataProvider = ac; } Sample XML feed: <?xml version="1.0" encoding="iso-8859-1" standalone="yes"?> <feed xml:base="http://www.test.com/Test/my.svc/" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns="http://www.w3.org/2005/Atom"> <title type="text">Test_Locations</title> <id>http://www.test.com/test/my.svc/Test_Locations</id> <updated>2010-04-27T20:41:23Z</updated> <link rel="self" title="Test_Locations" href="Test_Locations" /> <entry> <id>1</id> <title type="text"></title> <updated>2010-04-27T20:41:23Z</updated> <author> <name /> </author> <link rel="edit" title="Test_Locations" href="http://www.test.com/id=1" /> <category term="MySQLModel.Test_Locations" scheme="http://schemas.microsoft.com/ado/2007/08/dataservices/scheme" /> <content type="application/xml"> <m:properties> <d:FieldLocation>Test Location</d:FieldLocation> <d:Locationid>test0129</d:Locationid> </m:properties> </content> </entry> <entry> <id>2</id> <title type="text"></title> <updated>2010-04-27T20:41:23Z</updated> <author> <name /> </author> <link rel="edit" title="Test_Locations" href="http://www.test.com/id=2" /> <category term="MySQLModel.Test_Locations" scheme="http://schemas.microsoft.com/ado/2007/08/dataservices/scheme" /> <content type="application/xml"> <m:properties> <d:FieldLocation>Yet Another Test Location</d:FieldLocation> <d:Locationid>test25</d:Locationid> </m:properties> </content> </entry> </feed>

Should a developer write their own test plan for Q/A?

- by Mat Nadrofsky

Who writes the test plans in your shop? Who should write them? I realize developers (like me) regularly do their own unit testing whilst developing and in some cases even their own Q/A depending on the size of the shop and the nature of the business, but in a big software shop with a full development team and Q/A team, who should be writing those official "my changes are done now" test plans? Soon, we'll be bringing on another Q/A member to our development team. My question is, going forward, is it a good practice to get your developers to write their own test plans? Something tells me that part of that might make sense but another part might not... What I like about that: Developer is very familiar with the changes made, thus it's easy to produce a document... What I don't like about that: Developer knows how it's supposed to work and might write a test plan that caters to this without knowing it. So, with the above in mind, what is the general stance on this topic? I'm of course already reading books like the Mythical Man-Month, Code Complete and a few others which really do help, but I'd like to get some input from the group as well.

Performance issues when using SSD for a developer notebook (WAMP/LAMP stack)?

- by András Szepesházi

I'm a web application developer using my notebook as a standalone development environment (WAMP stack). I just switched from a Core2-duo Vista 32 bit notebook with 2Gb RAM and SATA HDD, to an i5-2520M Win7 64 bit with 4Gb RAM and 128 GB SDD (Corsair P3 128). My initial experience was what I expected, fast boot, quick load of all the applications (Eclipse takes now 5 seconds as opposed to 30s on my old notebook), overall great experience. Then I started to build up my development stack, both as LAMP (using VirtualBox with a debian guest) and WAMP (windows native apache + mysql + php). I wanted to compare those two. This still all worked great out, then I started to pull in my projects to these stacks. And here came the nasty surprise, one of those projects produced a lot worse response times than on my old notebook (that was true for both the VirtualBox and WAMP stack). Apache, php and mysql configurations were practically identical in all environments. I started to do a lot of benchmarking and profiling, and here is what I've found: All general benchmarks (Performance Test 7.0, HDTune Pro, wPrime2 and some more) gave a big advantage to the new notebook. Nothing surprising here. Disc specific tests showed that read/write operations peaked around 380M/160M for the SSD, and all the different sized block operations also performed very well. Started apache performance benchmarking with Apache Benchmark for a small static html file (10 concurrent threads, 500 iterations). Old notebook: min 47ms, median 111ms, max 156ms New WAMP stack: min 71ms, median 135ms, max 296ms New LAMP stack (in VirtualBox): min 6ms, median 46ms, max 175ms Right here I don't get why the native WAMP stack performed so bad, but at least the LAMP environment brought the expected speed. Apache performance measurement for non-cached php content. The php runs a loop of 1000 and generates sha1(uniqid()) inisde. Again, 10 concurrent threads, 500 iterations were used for the benchmark. Old notebook: min 0ms, median 39ms, max 218ms New WAMP stack: min 20ms, median 61ms, max 186ms New LAMP stack (in VirtualBox): min 124ms, median 704ms, max 2463ms What the hell? The new LAMP performed miserably, and even the new native WAMP was outperformed by the old notebook. php + mysql test. The test consists of connecting to a database and reading a single record form a table using INNER JOIN on 3 more (indexed) tables, repeated 100 times within a loop. Databases were identical. 10 concurrent threads, 100 iterations were used for the benchmark. Old notebook: min 1201ms, median 1734ms, max 3728ms New WAMP stack: min 367ms, median 675ms, max 1893ms New LAMP stack (in VirtualBox): min 1410ms, median 3659ms, max 5045ms And the same test with concurrency set to 1 (instead of 10): Old notebook: min 1201ms, median 1261ms, max 1357ms New WAMP stack: min 399ms, median 483ms, max 539ms New LAMP stack (in VirtualBox): min 285ms, median 348ms, max 444ms Strictly for my purposes, as I'm using a self contained development environment (= low concurrency) I could be satisfied with the second test's result. Though I have no idea why the VirtualBox environment performed so bad with higher concurrency. Finally I performed a test of including many php files. The application that I mentioned at the beginning, the one that was performing so bad, has a heavy bootstrap, loads hundreds of small library and configuration files while initializing. So this test does nothing else just includes about 100 files. Concurrency set to 1, 100 iterations: Old notebook: min 140ms, median 168ms, max 406ms New WAMP stack: min 434ms, median 488ms, max 604ms New LAMP stack (in VirtualBox): min 413ms, median 1040ms, max 1921ms Even if I consider that VirtualBox reached those files via shared folders, and that slows things down a bit, I still don't see how could the old notebook outperform so heavily both new configurations. And I think this is the real root of the slow performance, as the application uses even more includes, and the whole bootstrap will occur several times within a page request (for each ajax call, for example). To sum it up, here I am with a brand new high-performance notebook that loads the same page in 20 seconds, that my old notebook can do in 5-7 seconds. Needless to say, I'm not a very happy person right now. Why do you think I experience these poor performance values? What are my options to remedy this situation?

How do i tell if my drivers are up to date on Acer?

- by joe

Hoping some kind souls can help me out ? I got a blue screen the other day after trying to load sandboxie. So its obviously conflicting with something. I checked if my drivers were up to date on my acer aspire one AOD270 on this intel based site; http://www.drivermanager.com/en/down...tel&Logo=intel Its showing i have 2 drivers that need updating ; Intel NM10 Express chipset and the Realtek PCIE Cardreader. I have no idea whether to do the update via the Intel Driver update site or the Acer drivers download page? I then ran Bluescreenview and on the dump file its showing ; ''caused by driver'' igdkmd32.sys ''file description'' Intel (R) WDDM Kernel mode driver ''product name''Intel Graphics Accelerator Drivers for Windows 7(R) I bought the laptop here in SE Asia about a year ago. The ''HOT!! NEW download tool'' on the acer drivers site (below) doesnt seem to work and the info about removing and installing drivers is limited. Not sure what to trust on non acer/manufacturer sites. http://support.acer.com/us/en/produc...1&modelId=4040 I've located the igdkmd32.sys file inside the INTEL GRAPHICS MEDIA ACCELERATOR 3600 SERIES 8.14.8.1064. When i click on ''update driver'' in control panel it searches and says its up to date. In windows maintenance it says this intel had a problem, but no solution. For all i know my drivers could be up to date and its something else. Can anybody advise a dummy step by step the process i should follow ? I've never done this before. eg do i delete the old driver first and then download the new one.how much of a problem i could cause by downloading this type of thing wrongly? As yet i havent downloaded any drivers. I've asked on other forums but no luck as yet. Thanks for any help!

(manually configured) kernel update leaves wireless in a mess

- by Mala

I recently upgraded my kernel from 2.6.31-gentoo-r6 to 2.6.32-gentoo-r7. In both cases, I configured everything manually. However, since the upgrade, my wireless card appears to be on the fritz. It will connect to networks just fine, and remain connected, but can only access the internet (and other hosts on the network) for about 3 seconds after connecting. Reconnecting to the network appears to fix the problem... for another 3 seconds or so. The problem is "solved" by booting into the older kernel. The relevant lspci entry is 02:00.0 Network controller: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection I'm pretty sure I have the correct drivers enabled in the kernel Device Drivers ---> Network device support ---> Wireless LAN (IEEE 802.11) ---> <*> Intel Wireless Wifi [*] Enable LED support in iwlagn and iwl3945 drivers [*] Enable Spectrum Measurement in iwlagn driver [*] Enable full debugging output in iwlagn and iwl3945 drivers <*> Intel Wireless WiFi Next Gen AGN (iwlagn) [*] Intel Wireless WiFi 4965AGN [*] Intel Wireless WiFi 5000AGN; Intel WiFi Link 1000, 6000, and 6050 Series I tried with the other intel drivers enabled as well (iwl3945) and no difference. Is there something stupid I'm missing? Is there something I have to recompile after upgrading the kernel (a la nvidia)? Thanks Mala

Any program to help me check whether an ethernet channel can support full-length VLAN packet?

- by Jimm Chen

Sometimes, I have to face such a situation that I need to quickly and explicitly know whether a full length VLAN packet can traverse between two RJ45 ports. Yes, I mean 802.1Q ethernet frame with Etype=81 00 (diagram below). What I can do now is: Get two Windows PCs, for each PC, intall Intel Gigabit NIC and Intel specific driver to create a virtual NIC, with VLAN ID=3 assigned. Then connect the two PCs to each of the two RJ45 port. Finally execute ping to generate a full-length ethernet packet. ping -f -l 1472 <dest-IP> This way, I can be sure that the sent packet has the maximum "IP data payload" of 1500 bytes(8 bytes of ICMP header and 1472 bytes of ICMP data). If the ping gets reply, I know that the ethernet channel support full-length VLAN packet. From my experiment, some home switch or broad band routers(e.g. Linksys WRT54G) does not support full-length VLAN packet switching, so only ping -f -l 1468 succeeds. You see, I have to use an expensive Intel NIC to carry on that test, quite inconvenient. You know, for most laptop today, they do not equip an Intel NIC, and, even it is an Intel NIC, Intel VLAN driver, Intel has limitations on the models on which VLAN driver can be installed. So, my question is: Is there a small program that can let me send a full-length VLAN packet without installing a dedicated VLAN driver? Or better, the program has a stock feature that does the very job for my situation. Windows programs preferred, Linux solution welcome. Simpler the program, the better. Thank you.

Bug Triage

In this blog post brain dump, I'll attempt to describe the process my team tries to follow when dealing with new bug reports (specifically, code defect reports). This is not official Microsoft policy, just the way we do things… if you do things differently and want to share, you can do so at the bottom in the comments (or on your blog).Feature Triage TeamA subset of the feature crew, the triage team (which has representations from the PM, Dev and QA disciplines), looks at all unassigned bugs at regular intervals. This can be weekly or daily (or other frequency) dependent on which part of the product cycle we are in and what the untriaged bug load looks like. They discuss each bug considering the evidence and make a decision of whether the bug goes from Not Yet Assigned to Assigned (plus the name of the DEV to fix this) or whether it goes from Active to Resolved (which means it gets assigned back to the requestor for closure or further debate if they were not present at the triage meeting). Close to critical milestones, the feature triage team needs to further justify bugs they take to additional higher-level triage teams.Bug Opened = Not Yet AssignedSomeone (typically an SDET from the QA team) creates the bug item (e.g. in TFS), ensuring they populate all the relevant fields including: Title, Description, Repro Steps (including the Actual Result at the end of the steps), attachments of code and/or screenshots, Build number that they observed the issue in, regression details if applicable, how it was found, if a test case exists or needs to be created etc. They also indicate their opinion on the Priority and Severity. The bug status is left as Not Yet Assigned."Issue" versus "Fix for issue"The solution to some bugs is easy to determine, e.g. "bug: the column name is misspelled". Obviously the fix is to correct the spelling – still, the triage team should be explicit and enter the correct spelling in the bug's Description. Note that a bad bug name here would be "bug: fix the spelling of the column" (it describes the solution, rather than the problem).Other solutions are trickier to establish, e.g. "bug: the column header is not accessible (can only be clicked on with the mouse, not reached via keyboard)". What is the correct solution here? The last thing to do is leave this undetermined and just assign it to a developer. The solution has to be entered in the description. Behind this type of a bug usually hides a spec defect or a new feature request.The person opening the bug should focus on describing the issue, rather than the solution. The person indicates what the fix is in their opinion by stating the Expected Result (immediately after stating the Actual Result). If they have a complex suggested solution, that should be split out in a separate part, but the triage team has the final say before assigning it. If the solution is lengthy/complicated to describe, the bug can be assigned to the PM. Note: the strict interpretation suggests that any bug with no clear, obvious solution is always a hole in the spec and should always go to the PM. This also ensures the spec gets updated.Not Yet Assigned - Not Yet Assigned (on someone else's plate)If the bug is observed in our feature, but the cause is actually another team, we change the Area Path (which is the way we identify teams in TFS) and leave it as Not Yet Assigned. The triage team may add more comments as appropriate including potentially changing the repro steps. In some cases, we may even resolve the bug in our area path and open a new bug in the area path of the other team.Even though there is no action on a dev on the team, the bug still needs to be tracked. One way of doing this is to implement some notification system that informs the team when the tracked bug changed status; another way is to occasionally run a global query (against all area paths) for bugs that have been opened by a member of the team and follow up with the current owners for stale bugs.Not Yet Assigned - ResolvedThis state transition can only be made by the Feature Triage Team.0. Sometimes the bug description is not clear and in that case it gets Resolved as More Information Needed, so the original requestor can provide it.After understanding what the bug item is about, the first decision is to determine whether it needs to go to a dev.1. If it is a known bug, it gets resolved as "Duplicate" and linked to the existing bug.2. If it is "By Design" it gets resolved as such, indicating that the triage team does not think this is a bug.3. If the bug does not repro on latest bits, it is resolved as "No Repro"4. The most painful: If it is decided that we cannot fix it for this release it gets resolved as "Postponed" or "Won't Fix". The former is typically due to resources and time constraints, while the latter is due to deciding that it is not important enough to consume our resources in any release (yes, not all bugs must be fixed!). For both cases, there are other factors that contribute to the decision such as: existence of a reasonable workaround, frequency we expect users to encounter the issue, dependencies on other team to offer a solution, whether it breaks a core scenario, whether it prohibits customer feedback on a major feature, is it a regression from a previous release, impact of the fix on other partner teams (e.g. User Education, User Experience, Localization/Globalization), whether this is the right fix, does the fix impact performance goals, and last but not least, severity of bug (e.g. loss of customer data, security threat, crash, hang). The bar for fixing a bug goes up as the release date approaches. The triage team becomes hardnosed about which bugs to take, while the developers are busy resolving assigned bugs thus everyone drives for Zero Bug Bounce (ZBB). ZBB is when you have 0 active bugs older than 48 hours.Not Yet Assigned - AssignedIf the bug is something we decide to fix in this release and the solution is known, then it is assigned to a DEV. This is either the developer that will do the work, or a Lead that can further assign it to one of his developer team based on a load balancing algorithm of their choosing.Sometimes, the triage team needs the dev to do some investigation work before deciding whether to take the fix; similarly, the checkin for the fix may be gated on code review by the triage team. In these cases, these instructions are provided in the comments section of the bug and when the developer is done they notify the triage team for final decision.Additionally, a Priority and Severity (from 0 to 4) has to be entered, e.g. a P0 means "drop anything you are doing and fix this now" whereas a P4 is something you get to after all P0,1,2,3 bugs are fixed.From a testing perspective, if the bug was found through ad-hoc testing or an external team, the decision is made whether test cases should be added to avoid future regressions. This is communicated to the QA team.Assigned - ResolvedWhen the developer receives the bug (they should be checking daily for new bugs on their plate looking at bugs in order of priority and from older to newer) they can send it back to triage if the information is not clear. Otherwise, they investigate the bug, setting the Sub Status to "Investigating"; if they cannot make progress, they set the Sub Status to "Blocked" and discuss this with triage or whoever else can help them get unblocked. Once they are unblocked, they set the Sub Status to "Working on Solution"; once they are code complete they send a code review request, setting the Sub Status to "Fix Available". After the iterative code review process is over and everyone is happy with the fix, the developer checks it in and changes the state of the bug from Active (and Assigned to them) to Resolved (and Assigned to someone else).The developer needs to ensure that when the status is changed to Resolved that it is assigned to a QA person. For example, maybe the PM opened the bug, but it should be a QA person that will verify the fix - the developer needs to manually change the assignee in that case. Typically the QA person will send an email to the original requestor notifying them that the fix is verified.Resolved - ??In all cases above, note that the final state was Resolved. What happens after that? The final step should be Closed. The bug is closed once the QA person verifying the fix is happy with it. If the person is not happy, then they change the state from Resolved to Active, thus sending it back to the developer. If the developer and QA person cannot reach agreement, then triage can be brought into it. An easy way to do that is change the status back to Not Yet Assigned with appropriate comments so the triage team can re-review.It is important to note that only QA can close a bug. That means that if the opener of the bug was a PM, when the bug gets resolved by the dev it may land on the PM's plate and after a quick review, the PM would re-assign to an SDET, which is the only role that can close bugs. One exception to this is if the person that filed the bug is external: in that case, we leave it Resolved and assigned to them and also send them a notification that they need to verify the fix. Another exception is if specialized developer knowledge is needed for verifying the bug fix (e.g. it was a refactoring suggestion bug typically not observable by the user) in which case it is fine to have a developer verify the fix, and ideally a different developer to the one that opened the bug.Other links on bug triageA quick search reveals that others have talked about this subject, e.g. here, here, here, here and here.Your take?If you have other best practices your team uses to deal with incoming bug reports, feel free to share in the comments below or on your blog.

Why version of chrome does not matter much more then firefox and firefox does not matter much as IE

- by anirudha

Everything not perfect. in software the software make and growth by user feedback like what user expected from the software and want in next version of software. In a chrome Event i hear about the Chromium. you can find some interesting things here Video 1 Video 2 come to the point. when i hear about some good website of india. many of them talking a little thing in common that. We are #1 because we not thing that we make a great application and deploy them and think that we finished own works preharps in a small days we make a small website deploy them and improve them always latter. what the point they all talking about:- the conclusion is that software make by user feedback. they tell that he not spent much time and wait for a long time when their project was finish and they launch their website. preharps they tell that they make a small website in a small time and launched them. make a research on them later and make them better later and website growth as they thing. if they are late then someone else can win even their project was much good them other. not more but a little story:- before few month i hear about a great website who sold many of books daily i myself purchase some from them to track how they work and how they provided service. i not found any problem with their service. the service they provided is good but when i see their website i found that the mockup code was very badly designed. i am not know the matter how they growth because they used very other stuff who make their website slow. when i research something more i found that their is very hard to implement the website look like them. on their blog they writing about a mail they have. the clone of them make by many other but not goes good as well as they make. after few month later website is looking great. many thing they improved and make them better as other thing. a another conclusion that same as another story that user feedback. well now come to the point. we talking about Chrome,firefox and IE. what thing is goes common that they all are browser. but something goes different that Chrome is a one of the best browser. from a month many of issue submitted to chrome that user found when they use them. so what is make this different the different is that when feedback goes to someone they take a action and think to make them better so improvement of chrome based on feedback user put using many things. secondly because it's goes open-source many of developer contribute them and make them real browser not real [tape] browser as like IE [a good example]. as you see in video they talking about silent update in chrome and futurecoming chromium. the thing they implement is too good. because by this thing user not worry about a new version. i myself never find a problem that you need to user new version as we found same problem in other application. Well think are great in chrome and now talking about Firefox. Firefox is a best option for development as well as chrome best for surfing the internet. in firefox many thing are great like plugin [ex: Firebug] , addons personas themes and many other thing and customization in firefox make them really a browser not like a joker [IE a good example]. well now come to IE. are IE really great no. someone from Microsoft can say that ha ha hi hi because they can't see the power of open-source. they thing that they make a software and they never need user feedback because they produced windows who really great for user because they used them. example :- before few month Microsoft shipped Windows live. when i use them that i found that their is no sense make for using this one software. suppose you need to write a post through Live writer. the old version are great i myself have no problem but in 2011 i found that they changed everything in user interface. so learn a new thing and spent sometime more to learn a new version whenever need are same and feature are same so why user spent a little time more to learn a lesson who they want to teach even their is no sense to learn them. the problem in 2011 Live not only of mine their are many other have same problem as mine and forget live 2011 after the see a badly design user interface. even they tell we maked in WPF yeah yeah WPF we make in .net. are you can say that what is the matter .net for user. the user have no problem to use WPF based application even you make them fool as we make them in WPF 2020 they are future technologies and we launch it 10 year before only for you yeah you dear customer of mine. yeah they thing WPF is best and thing to implement every software they make even they forget to make better user interface but they also remember to make them next version in WPF. the IE 9 Rc release on 10 febuary. but are they really cool. how much feedback they take and take action of them. their is no answer because they thing to launch a software they never thing what user want and off-course not care of user feedback. as we mention in Firefox and in chrome user feedback have a big matter because sound come from a public and user who use the software not only who make them software as IE 9 have. so feedback take a opportunities to make their software better and less hassel to use them in user hands not only in developer hands. so IE9 is not a good guys who still need of user if they really want a experience. well what Microsoft implemented in IE. i am not talking about that furthure more but i found in article last days[why not say reading a google blog] yeah see them in http://googleblog.blogspot.com/2011/02/microsofts-bing-uses-google-search.html Well their is nothing good for developer in IE9. the blah blah blah they can always said on MSDN and many other site they have. many from public talking about them because they never can see a good software outside Microsoft. they never talking about Firebug even in books they never show you that. well i know competitor never show you a stuff of competitor i have same issue from Yahoo. on a days i hear from newsletter from them they write a subline on the bottom that USE IE or Firefox to exerience better Web. i am agree with Firefox and i am not know they really talking about IE or joking but i never believe they forget to put chrome. well i know their is corporate rule everyone should follow first. so no problem yahoo i know the matter. well IE:- so what is IE and Why We should use IE. well their is no sense to use IE. the thing we expect from IE but never found that:- first thing is that as a developer we thing the customization as well as other browser have like in chrome have it's own customization and firefox is also great in this matter. but IE really for Web development. are you joking:- the thing they mention in their blog is that IE9 have a new developer tool who have three new panel or tabs. are this joke whenever Firefox and chrome have everyday a new plugin or great upgrade of old plugin they tell we add three new panel first is network second is blah third is blah. well nice joke you make all MSDN blogger i like the way you talking about IE. even we know what matter the browser have. i thing whenever they make IE 6 they talking about IE as same as they talking today. Secondly their is no other tool to use with IE deveoper tool like Firebug is avilable in IE but not make by IE. firebug team themselves make them for IE. because many of developer thing to use firebug but can't use because they still goes mad about IE because day and night they only hear about tools maked by Microsoft. so no plugin [even very small developer tool] no customized no personas on themse. no update yeah why forget these topic come with us and share a little thing more. IE launch IE 6 after 7 after 8 and now 9 [even in future] but what they do. they do nothing on user feedback they still thing WPF is great because colors make user cool and they forget to implement other things as other already provide. Chrome and Firefox are come after IE. Mozilla firefox come in 2004 and chrome is late in 2008. even they are late they still focus on Developer and thing they feel first is that customization like developer tool , themese and perfsonas and many other great things. are they can find in IE even next i means 10 yeah IE10 never because they thing only making a software or force user to use new version of OS. i am confused that why not wait and force user to purchase windows 8 instead of 7. so IE have no customization even small developer tool i thing that they make a customizable interface like in firefox who configure by about:config. so thing is discussed about really not a point we thing to goes but now it's clear what is making no matter for version in Firefox and chrome. because chrome and firefox not wait for a long time and explode a bomb to make publicity. they still work and make upgrade possible to user as soon as possible. [chrome never tell about they goes old they himself update them].so update comes soon in Firefox and in chrome but in IE their is a long time to wait and they make them without feedback. so IE really not for human and not really for us. whenver you found a bug in chrome and in firefox you report them and found that they are work in progressed and can be see in next version of firefox. but what you see whenever you see IE. you found that what the bug can found in IE whenver they not implemented same feature in IE. well IE 9 is next IE6 for developer. conclusion:- after reading a whole post you find that i hate all thing about IE. why are i write a big post on a small pity software IE. why i open the poll of IE. are their anything in IE break my heart. are their is something goes wrong with me and with my IE9. are their is anything i got with IE9. why i write a big post. well as a developer play a trick that give sometime to chrome to make them better and some other to make firefox better and feel something you contribute really have a matter as a contribute you find some other and their thought on same software. some are great maybe some of them blah blah. but are their is true that outside Microsoft their is no good sollution can make because it's outside Microsoft. their is not true. the thing developer make not have matter even using Microsoft technologies or outside technologies of MS. so stop this i not want to talking some other things just stop it. i means their is no more blah i want to talking with you for IE.i still hate them and believe it is next IE6 for Web. Answers: if you still need a answer in lines that the answer is that IE late update as long as they can and also make force user to upgrade IE9 because they want to promote windows first then thing about IE and chrome and firefox not do that as same as IE. so IE is late and user forced software. in firefox and chrome upgrade come soon as soon as they possible. Thanks to give me a great time and red my blah on Blah i means IE9 Thanks again Anirudha
