• Ubuntu 10.04 recognizing USB 2.0 external HD as USB 1.1

  When I connect the USB 2.0 drive I see this: usb 1-4.3: new full speed USB device using ohci_hcd and address 5 so I know it's getting seen as USB 1.1. usb-devices shows that it really is USB 2.0 and connected to a USB 2.0 hub: T: Bus=01 Lev=01 Prnt=01 Port=03 Cnt=01 Dev#= 2 Spd=12 MxCh= 4 D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=05e3 ProdID=0608 Rev=77.61 S: Product=USB2.0 Hub C: #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=100mA I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub T: Bus=01 Lev=02 Prnt=02 Port=01 Cnt=01 Dev#= 4 Spd=12 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=13fd ProdID=1340 Rev=02.10 S: Manufacturer=Generic S: Product=External C: #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr=2mA I: If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.)

• Java JRE 1.6.0_35 Certified with Oracle E-Business Suite

  - by Steven Chan (Oracle Development)

  The latest Java Runtime Environment 1.6.0_35 (a.k.a. JRE 6u35-b10) is now certified with Oracle E-Business Suite Release 11i and 12 desktop clients.   What's new in Java 1.6.0_35?See the 1.6.0_35 Update Release Notes for details about what has changed in this release.  This release is available for download from the usual Sun channels and through the 'Java Automatic Update' mechanism. 32-bit and 64-bit versions certified This certification includes both the 32-bit and 64-bit JRE versions. 32-bit JREs are certified on: Windows XP Service Pack 3 (SP3) Windows Vista Service Pack 1 (SP1) and Service Pack 2 (SP2) Windows 7 and Windows 7 Service Pack 1 (SP1) 64-bit JREs are certified only on 64-bit versions of Windows 7 and Windows 7 Service Pack 1 (SP1). Worried about the 'mismanaged session cookie' issue? No need to worry -- it's fixed.  To recap: JRE releases 1.6.0_18 through 1.6.0_22 had issues with mismanaging session cookies that affected some users in some circumstances. The fix for those issues was first included in JRE 1.6.0_23. These fixes will carry forward and continue to be fixed in all future JRE releases.  In other words, if you wish to avoid the mismanaged session cookie issue, you should apply any release after JRE 1.6.0_22.All JRE 1.6 releases are certified with EBS upon release Our standard policy is that all E-Business Suite customers can apply all JRE updates to end-user desktops from JRE 1.6.0_03 and later updates on the 1.6 codeline.  We test all new JRE 1.6 releases in parallel with the JRE development process, so all new JRE 1.6 releases are considered certified with the E-Business Suite on the same day that they're released by our Java team.  You do not need to wait for a certification announcement before applying new JRE 1.6 releases to your EBS users' desktops. Important For important guidance about the impact of the JRE Auto Update feature on JRE 1.6 desktops, see: URGENT BULLETIN: All E-Business Suite End-Users Must Manually Apply JRE 6 Updates References Recommended Browsers for Oracle Applications 11i (Metalink Note 285218.1) Upgrading Sun JRE (Native Plug-in) with Oracle Applications 11i for Windows Clients (Metalink Note 290807.1) Recommended Browsers for Oracle Applications 12 (MetaLink Note 389422.1) Upgrading JRE Plugin with Oracle Applications R12 (MetaLink Note 393931.1) Related Articles Mismanaged Session Cookie Issue Fixed for EBS in JRE 1.6.0_23 Roundup: Oracle JInitiator 1.3 Desupported for EBS Customers in July 2009

• Playing with F#

  - by mroberts

  Project Euler is a awesome site.   When working with a new language it can be tricky to find problems that need solving, that are more complex than "Hello World" and simpler than a full blown application. Project Euler gives use just that, cool and thought provoking problems that usually don't take days to solve.  I've solved a number of questions with C# and some with Java.  BTW, I used Java because it had BigInteger support before .Net. A couple weeks ago, back when winter had a firm grip on Columbus, OH, I began playing (researching) with F#.  I began with Problem #1 from Project Euler.  I started by looking at my solution in C#. Here is my solution in C#. 1: using System; 2: using System.Collections.Generic; 3:   4: namespace Problem001 5: { 6: class Program 7: { 8: static void Main(string[] args) 9: { 10: List<int> values = new List<int>(); 11:   12: for (int i = 1; i < 1000; i++) 13: { 14: if (i % 3 == 0 || i % 5 == 0) 15: values.Add(i); 16: } 17: int total = 0; 18:   19: values.ForEach(v => total += v); 20:   21: Console.WriteLine(total); 22: Console.ReadKey(); 23: } 24: } 25: }   Now, after much tweaking and learning, here is my solution in F#.   1: open System 2:   3: let calc n = 4: [1..n] 5: |> List.map (fun x -> if (x % 3 = 0 || x % 5 = 0) then x else 0) 6: |> List.sum 7:   8: let main() = 9: calc 999 10: |> printfn "result = %d" 11: Console.ReadKey(true) |> ignore 12:   13: main() Just this little example highlights some cool things about F#. Type inference. F# infers the type of a value.  In the C# code above we declare a number of variables, the list, and a couple ints.  F# does not require this, it infers the calc (a function) accepts a int and returns a int. Great built in functionality for Lists.  List.map for example. BTW, I don’t think I’m spilling the beans by giving away the code for Problem 1.  It by far is the easiest question, IMHO, solved by 92,000+ people. Next I’ll look into writing a class library with F#.

• System freezes while not in use, how do I fix this?

  - by PHLAK

  Bare with me, the following is a bit winded. I have Ubuntu 10.10 Desktop 64-bit installed on my laptop and up until a few weeks ago it has been running great. Then one day, while I was not using the laptop it froze. I was logged in as my user but had locked the screen locked and closed the lid. I didn't notice that it had frozen until I opened the lid and wiggled the mouse to try and log in. The screen remained black and I got no response. I immediately tried Alt + F2, F3, F4, etc. but got no response. The only thing I could do was hold the power button to power off the machine. The freezing has happened as quickly as within 10-20 minutes of the system being logged off and lid closed and as long as 4-6 hours. My machine is NOT configured to go into standby when plugged in and this has happened both on AC power and battery. Troubleshooting I have performed: I uninstalled programs I knew that I had installed between when it was working fine and having problems. Those programs were CrashPlan, Shutter and Conky. After uninstalling ALL of these programs the freezing still occurs. Next, I decided to SSH into the machine from my desktop and leave an htop and tail of the syslog running. Here are screenshots of the last thing shown on both when the system froze: htop, syslog Here is a dump of my syslog after another freeze. The freeze happened at 9:14 and I didn't notice it until about 10 minutes later and rebooted, hence the 10 minute gap from 9:14 to 9:24. In the above syslog dump I noticed a lot of NVRM: os_raise_smp_barrier(), invalid context! and upon investigating that message learned it was from the proprietary Nvidia driver I had installed. Thinking this could be part of the problem I uninstalled the Nvidia driver and reverted to using the Nouveau driver. The computer still froze after a few hours. Lastly, thinking the problem could be caused by overheating I used compressed air to blow out any dust in the CPU vents and all other openings on the laptop. None of the above troubleshooting has helped and the freezing still occurs. What other steps can I take to troubleshoot and/or fix this problem? Note: Yesterday X started to eat up a lot of CPU power and eventually froze my system while I was forwarding an X session over SSH (from another PC to my laptop). I'm unsure if this is related or not as it doesn't match any of the symptoms of the problem above. Aside from this, the system has never frozen while in use, even under heavy load. EDIT: I just ran Memtest86+ and it made it through two passes without any errors. Just eliminating possible causes here.

• Programming methodologies at stackoverflow

  - by Prototype Stark

  I am in the middle of starting up a software company where we would use ASP.NET MVC and ASP.NET WebAPI extensively at shop. We will be a group of 4 and no more than 10 will work on any particular project at any point in time(these are ground rules). I would like to know, what programming methodologies best suit a small(guerilla) team. Specifically, I would also like to know which ones are being used at famous ASP.NET MVC shops like Stackoverflow. The ones I know are: Scrum and Waterfall(I know its bad). But what's the recommended way of development for smaller, group of 9-10 team. Also, will Test Driven Development help such a team in producing quality software? Are there any other techniques the team will have to know to be good at producing quality software?

• Retrieving snapshots of game statistics

  - by SatheeshJM

  What is a good architecture for storing game statistics, so that I can retrieve snapshots of it at various moments? Say I have a game, and the user's statistics initially are: { hours_played = 0, games_played = 0, no_of_times_killed = 0, } When the user purchases something for the first time from within the game, the stats are { hours_played = 10, games_played = 2, no_of_times_killed = 5, } And when he purchases something for the second time, the stats are { hours_played = 20, games_played = 4, no_of_times_killed = 10, } Let me name the events as "purchase1" and "purchase2" How do I model my statistics, so that at any point in the future, I will be able to retrieve the snapshot of the statistics at the time when "purchase1" was fired. Similarly for "purchase2" and any other event I will add. Hope that made sense..

• Oracle NoSQL Database Exceeds 1 Million Mixed YCSB Ops/Sec

  - by Charles Lamb

  We ran a set of YCSB performance tests on Oracle NoSQL Database using SSD cards and Intel Xeon E5-2690 CPUs with the goal of achieving 1M mixed ops/sec on a 95% read / 5% update workload. We used the standard YCSB parameters: 13 byte keys and 1KB data size (1,102 bytes after serialization). The maximum database size was 2 billion records, or approximately 2 TB of data. We sized the shards to ensure that this was not an "in-memory" test (i.e. the data portion of the B-Trees did not fit into memory). All updates were durable and used the "simple majority" replica ack policy, effectively 'committing to the network'. All read operations used the Consistency.NONE_REQUIRED parameter allowing reads to be performed on any replica. In the past we have achieved 100K ops/sec using SSD cards on a single shard cluster (replication factor 3) so for this test we used 10 shards on 15 Storage Nodes with each SN carrying 2 Rep Nodes and each RN assigned to its own SSD card. After correcting a scaling problem in YCSB, we blew past the 1M ops/sec mark with 8 shards and proceeded to hit 1.2M ops/sec with 10 shards.  Hardware Configuration We used 15 servers, each configured with two 335 GB SSD cards. We did not have homogeneous CPUs across all 15 servers available to us so 12 of the 15 were Xeon E5-2690, 2.9 GHz, 2 sockets, 32 threads, 193 GB RAM, and the other 3 were Xeon E5-2680, 2.7 GHz, 2 sockets, 32 threads, 193 GB RAM.  There might have been some upside in having all 15 machines configured with the faster CPU, but since CPU was not the limiting factor we don't believe the improvement would be significant. The client machines were Xeon X5670, 2.93 GHz, 2 sockets, 24 threads, 96 GB RAM. Although the clients had 96 GB of RAM, neither the NoSQL Database or YCSB clients require anywhere near that amount of memory and the test could have just easily been run with much less. Networking was all 10GigE. YCSB Scaling Problem We made three modifications to the YCSB benchmark. The first was to allow the test to accommodate more than 2 billion records (effectively int's vs long's). To keep the key size constant, we changed the code to use base 32 for the user ids. The second change involved to the way we run the YCSB client in order to make the test itself horizontally scalable.The basic problem has to do with the way the YCSB test creates its Zipfian distribution of keys which is intended to model "real" loads by generating clusters of key collisions. Unfortunately, the percentage of collisions on the most contentious keys remains the same even as the number of keys in the database increases. As we scale up the load, the number of collisions on those keys increases as well, eventually exceeding the capacity of the single server used for a given key.This is not a workload that is realistic or amenable to horizontal scaling. YCSB does provide alternate key distribution algorithms so this is not a shortcoming of YCSB in general. We decided that a better model would be for the key collisions to be limited to a given YCSB client process. That way, as additional YCSB client processes (i.e. additional load) are added, they each maintain the same number of collisions they encounter themselves, but do not increase the number of collisions on a single key in the entire store. We added client processes proportionally to the number of records in the database (and therefore the number of shards). This change to the use of YCSB better models a use case where new groups of users are likely to access either just their own entries, or entries within their own subgroups, rather than all users showing the same interest in a single global collection of keys. If an application finds every user having the same likelihood of wanting to modify a single global key, that application has no real hope of getting horizontal scaling. Finally, we used read/modify/write (also known as "Compare And Set") style updates during the mixed phase. This uses versioned operations to make sure that no updates are lost. This mode of operation provides better application behavior than the way we have typically run YCSB in the past, and is only practical at scale because we eliminated the shared key collision hotspots.It is also a more realistic testing scenario. To reiterate, all updates used a simple majority replica ack policy making them durable. Scalability Results In the table below, the "KVS Size" column is the number of records with the number of shards and the replication factor. Hence, the first row indicates 400m total records in the NoSQL Database (KV Store), 2 shards, and a replication factor of 3. The "Clients" column indicates the number of YCSB client processes. "Threads" is the number of threads per process with the total number of threads. Hence, 90 threads per YCSB process for a total of 360 threads. The client processes were distributed across 10 client machines.

• Inline template efficiency

  - by Darryl Gove

  I like inline templates, and use them quite extensively. Whenever I write code with them I'm always careful to check the disassembly to see that the resulting output is efficient. Here's a potential cause of inefficiency. Suppose we want to use the mis-named Leading Zero Detect (LZD) instruction on T4 (this instruction does a count of the number of leading zero bits in an integer register - so it should really be called leading zero count). So we put together an inline template called lzd.il looking like: .inline lzd lzd %o0,%o0 .end And we throw together some code that uses it: int lzd(int); int a; int c=0; int main() { for(a=0; a<1000; a++) { c=lzd(c); } return 0; } We compile the code with some amount of optimisation, and look at the resulting code: $ cc -O -xtarget=T4 -S lzd.c lzd.il $ more lzd.s .L77000018: /* 0x001c 11 */ lzd %o0,%o0 /* 0x0020 9 */ ld [%i1],%i3 /* 0x0024 11 */ st %o0,[%i2] /* 0x0028 9 */ add %i3,1,%i0 /* 0x002c */ cmp %i0,999 /* 0x0030 */ ble,pt %icc,.L77000018 /* 0x0034 */ st %i0,[%i1] What is surprising is that we're seeing a number of loads and stores in the code. Everything could be held in registers, so why is this happening? The problem is that the code is only inlined at the code generation stage - when the actual instructions are generated. Earlier compiler phases see a function call. The called functions can do all kinds of nastiness to global variables (like 'a' in this code) so we need to load them from memory after the function call, and store them to memory before the function call. Fortunately we can use a #pragma directive to tell the compiler that the routine lzd() has no side effects - meaning that it does not read or write to memory. The directive to do that is #pragma no_side_effect(<routine name), and it needs to be placed after the declaration of the function. The new code looks like: int lzd(int); #pragma no_side_effect(lzd) int a; int c=0; int main() { for(a=0; a<1000; a++) { c=lzd(c); } return 0; } Now the loop looks much neater: /* 0x0014 10 */ add %i1,1,%i1 ! 11 ! { ! 12 ! c=lzd(c); /* 0x0018 12 */ lzd %o0,%o0 /* 0x001c 10 */ cmp %i1,999 /* 0x0020 */ ble,pt %icc,.L77000018 /* 0x0024 */ nop

• Best sites to find good .NET Developers

  - by Mag20

  I am looking for good sites to post a position for a .NET developer. I already tried: Craig's list got about 10 resumes, but most couldn't answer our technical questions StackOverflow Careers no responses What sites did you have success with finding good developers? UPDATE 1: Wanted to provide some more information: My company is in NJ. We are a small startup. Less then 10 people. Monster, Dice, CareerBuilder all charge like $500 a month per posting. Seems a bit much. Also only Dice is specifically targeting technical positions. With monster and career builder I am a bit worried about having to go through hundreds of resumes that don't apply.

• Unable to configure/setup 5.1 audio with 12.04

  - by Vipin Vinayan

  I am kinda new to Ubuntu as well. I have been having this issue with audio for quite sometime now. Initially, when I installed version 11.10 (I guess), I was able to use my 5.1 speakers without any issues. If my memory serves me right, it was after an update that the 5.1 audio stopped working and the video resolution would not get saved. I temporarily fixed the resolution issue by creating a start-up shell script that would update the resolution and load it. But the issue with audio has been going on for quite sometime now. Even though I have option for 5.1, only two speakers seem to be working. I thought an upgrade should fix the issue and so upgraded the OS to version 12.04. I also tried uninstalling alsa and pulse audio, reinstalling them, changing the /etc/pulse/daemon.conf channels from 2 to 6. I have also tried installing pavucontrol but nothing seems to have worked and the issue still persists. Is there anything else you could suggest? The lspci log on my computer is as follows 00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 10) 00:01.0 PCI bridge: Intel Corporation 82G33/G31/P35/P31 Express PCI Express Root Port (rev 10) 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10) 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01) 00:1c.0 PCI bridge: Intel Corporation N10/ICH 7 Family PCI Express Port 1 (rev 01) 00:1c.1 PCI bridge: Intel Corporation N10/ICH 7 Family PCI Express Port 2 (rev 01) 00:1d.0 USB controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #1 (rev 01) 00:1d.1 USB controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #2 (rev 01) 00:1d.2 USB controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #3 (rev 01) 00:1d.3 USB controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #4 (rev 01) 00:1d.7 USB controller: Intel Corporation N10/ICH 7 Family USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) 00:1f.1 IDE interface: Intel Corporation 82801G (ICH7 Family) IDE Controller (rev 01) 00:1f.2 IDE interface: Intel Corporation N10/ICH7 Family SATA Controller [IDE mode] (rev 01) 00:1f.3 SMBus: Intel Corporation N10/ICH 7 Family SMBus Controller (rev 01) 03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

• How to restart WiFi interface without rebooting (it drops connection)?

  - by Dima

  I boot into ubuntu and it connects to the Wifi network fine. After about 10-15min the DNS stop resolving any website and a couple of minutes later network-managers tells me that I'm disconnected and tries to reconnect constantly to my router and fails to do it. Upon Ubuntu restart everything works fine for the first 10-15min again. When I boot into Mac OS X everything is fine with the same connection! How do I restart wifi interface? sudo ifdow wlan0 just tells me that wlan0 is not configured and wlan0 doesn't appear in /etc/network/interfaces either, which I find strange.... (unless network-manager is doing it behind my back).
