LXer: Microsoft KILLS Windows 8.1 Update 2 AND PATCH TUESDAY

Wednesday 6th of August 2014 02:14:56 AM
Microsoft has at last revealed the date when its second major update to Windows 8.1 will ship to customers: never. Despite months of speculation that the software giant has been planning to push out another major update roll-up for its latest OS this year, much like it did with the oddly named Windows 8.1 Update in April, Redmond mouthpiece Brandon LeBlanc blogged on Tuesday that we can forget it.

LXer: Open hardware resources from

Wednesday 6th of August 2014 12:20:34 AM
What's not to love about hardware? We use it every day. From the cars we drive to the computers we play with, from prosthetic hands to quadcopter drones, lots of things around us run on hardware of some sort. And like everything else, we believe strongly in applying the open source way to them. Sharing, accountability, and rapid iteration are all concepts that can benefit the hardware world.

Reddit: Slow access to swap partition

Tuesday 5th of August 2014 11:53:25 PM

This isn't a tech support request, more just a bit of strange behavior that I'm curious about.

I'm running Ubuntu 14.04 on a Sony Laptop:

  • Athlon II P320 Dual-Core Processor × 2
  • 2Gb RAM
  • AMD RS880 Video Card

For a long time I noticed that my computer ran well, until it started swapping. Then everything would grind to a halt, and just about everything would gray out. If I left it for a while, sometimes it would sort itself out, other times I would have to go into the terminal (itself a process that would take several minutes) and start killing processes. I played around with swappiness, which made it less common, but no better when it occured.

After getting really tired of dealing with this, I decided to do some testing with hdparm.

The following is my hard drive setup (its a Hitachi 320gb disk media or however you say it):

Device Boot Start End Blocks Id System /dev/sda1 * 2048 99999743 49998848 83 Linux /dev/sda2 100001790 625141759 262569985 5 Extended /dev/sda5 100001792 620142591 260070400 83 Linux /dev/sda6 620144640 625141759 2498560 82 Linux swap / Solaris

And my tests of each partition:

$ sudo hdparm -t /dev/sda1 /dev/sda1: Timing buffered disk reads: 206 MB in 3.00 seconds = 68.58 MB/sec $ sudo hdparm -t /dev/sda5 /dev/sda5: Timing buffered disk reads: 196 MB in 3.02 seconds = 64.81 MB/sec $ sudo hdparm -t /dev/sda6 /dev/sda6: Timing buffered disk reads: 104 MB in 3.05 seconds = 34.13 MB/sec

As you can see, access to the swap partition is half the speed of any other. Which is why, I believe, I was getting the Swapping Slowdowns of Death (tm). So I tried switching to a swap file placed in my root folder, and everything has gotten so much better. I can use my computer with all the proper multitasking again!

But why would this have happened? Aren't swap files supposed to be inherently slower than a swap partition? Or is there a lesson to be learned here?

TuxMachines: Rugged DAQ system runs real-time Linux

Tuesday 5th of August 2014 10:05:39 PM

NI unveiled a rugged 4-slot “CompactDAQ” system for data acquisition and control (DAQ), with real-time Linux, an Atom E3825, and optional sensor modules.

Usually, when you have a choice of Windows or Linux, the Windows version costs more. In the case of the National Instruments (NI) CompactDAQ cDAQ-9134 Controller, however, it’s the Linux version that costs $500 more, at $4,999. That’s because it’s a special real-time Linux variant called NI Linux Real-Time, also available on NI’s CompactRIO cRIO-9068 controller and sbRIO-9651 computer-on-module, both of which are based on the Xilinx Zynq-7020 system-on-chip. The cDAQ-9134 instead runs on a dual-core, 1.33GHz Intel Atom E3825 SoC.

Reddit: ELI5: What is the Linux kernel and what does it do?

Tuesday 5th of August 2014 10:02:43 PM

I'm fairly new to Linux(started using it six months ago). In that time I still have no idea what the Linux kernel is or does. I was reading the Wikipedia article about that discusses the Linux kernel and I still am unsure what exactly it is. So what exactly is the Linux kernel and what is its purpose?

Linuxaria: Check how much do you type with WhatPulse on Linux

Tuesday 5th of August 2014 09:57:50 PM

 If, like me, you are a statistics freak you must install this small application on all your computers: WhatPulse

The software tracks a user’s pressed keys, mouse clicks and used bandwidth and the uptime of the system. Periodically, or by hand, the user can upload to the server the number of keystrokes made; this is called “pulsing”.

Users can see where they are in a leaderboard of people who have joined the program and compare themselves against people from their own countries. Users can also join teams, which enables them to compare themselves against people with similar interests (Go Linux Users !!).

There is a basic, and free, version where you can easily see and check all the basic statistics and a premium account where you can see some more stats.

The software is available for Linux, Windows and Mac.

Registration on the website

As first step you have to register your account on the WhatPulse Website or as alternative when you first start the WhatPulse client there is a practical wizard through which each user has the option to create an account to upload their own statistics (you can also log in with Facebook).

You will be prompted to login, once you login, you have to search for your computers name, this is because you can login to several computers with this and they’ll all collectively go to the same statistic count. Once you’ve logged in, a small W will appear in your system tray, that’s it, your set up!

Installation of WhatPulse on Linux

The official website offer on the download page a generic version distributed via a .tar.gz archive (available for 32 and 64 bit) and a debian package.

Personally I’ve installed the debian package on my Mint Qiana and the Aur Package on My Arch Linux, no problems at all.

If you want to go with the generic installation please keep in mind that WhatPulse requires several libraries to function. Mainly Qt, because WhatPulse is built on Qt. Here’s a list of requirements:

- libQtCore
- libQtWebKit
- libqt4-sql
- libqt4-sql-sqlite
- openssl-devel (libssl-dev)
- libQtScript

Input Statistics
The client needs permissions to be allowed to read your keyboard/mouse input. Run the included interactive .sh script to set up these permissions.

Network Statistics
To enable the network measurements, you also need the package libpcap to allow WhatPulse to hook into the network traffic. If WhatPulse does not find libpcap, it will run but it will not display any network statistics.

Using the Application

By default WhatPulse will start automatically at the login of your graphical session and clicking on the W on your systray you’ll go to the Overview tab that gives a birds-eye view of all the different information gathered about your machine, for instance, the Linux version installed on your PC, processor model, RAM, GPU, total click counts, keystrokes and bandwidth usage. Clicking ‘Pulse’ under these information will upload the gathered data to the main server.

It’s also possible to select when automatically ‘Pulse’ the data to the server, such as every 50.000 clicks or 1 GB downloaded.

For further details, you can switch to each category’s pertaining tab. For example, the Input tab shows you the amount of key strokes and clicks your PC has registered during a certain time period. The time period can be sorted on a daily, weekly, monthly, yearly and all-time basis. The ‘all’ setting will show stats since the program was installed.

Below the keystrokes, you’ll find the keyboard heat map, which basically uses light and warm colors to shows what keys were used more than others during the selected time period, as shown in the screenshot above. Below that, the app displays the total amount of clicks registered in the selected period.

Under the Network tab, it’s possible to view the daily Internet usage. The application can monitor bandwidth usage of all the network devices, and even shows you bandwidth usage by country. Once again, you can navigate between available data using the arrow buttons at the top-right.

On the website you’ll see the sum of all your computer statistics with the same information available on the client.

Disclaimer: The link above to the WhatPulse website contains my referral link, using it when you register will give me a premium account for some time.

Hello /r/linux!

I am looking into potentially starting a Linux User Group in Romeo, Michigan. While it's not a huge town, there aren't any other groups within 40 or 50 miles of there.

Do any of you fellow Linux users live near Romeo and would be interested in a User Group there? Comment below!

Reddit: I'm at my wits end with this computer.

Tuesday 5th of August 2014 08:42:27 PM

So I was given a 20" iMac G5 ALS. It had no hard drive or memory originally, but I managed to track down 1GB of DDR400 and a 500GB SATA. Its got a Radeon 9600 graphics chip.

So, here's my problem: I cannot, for the life of me, get a damn OS on this computer. The many OS X discs I've tried will not install, in fact they don't even see the hard drive in the "Choose A Volume" window, however disk utility sees the drive and will even format it to HFS+. All first aid options fail with no error code.

Finally I gave up after a few days and tried to put a Linux Distro on it. All *buntu flavors hang at the same spot, a solid black screen that has so cursor immediately following the yaboot prompt. I've tried nosplash, PowerPC 64 (w and w/o nosplash) and all the radeon video options, (modeset=0, forcing a resolution, agpmode=-1, etc) on both Alternate and Live discs. No Dice.

Finally I tried to install MintPPC 11, I get the farthest on this one. It lets me choose keyboard layout, language, it downloads additional files, let's me choose a server, but hangs at 0% on the "Detecting Disks and Other Hardware."

My next plan after I get off work was to try plain Debian, since it actively supports PPC, I hesitated on this one at first because it not as user friendly as I'd like it to be, but whatever, I know how to read.

I know a lot of your are gonna say RTFM, but I have. Countless hours of reading documentation and forum searches. Has ANYBODY had success getting Linux on an iMac G5, and if so what the heck am I doing wrong.

Note: NO hotkeys work on this Mac. I've been booting from CD/DL-DVD using the OpenFirmware command "boot CD:,\:tbxi"

Help me, r/Linux, you're my only hope.

LXer: Meet Solaris 11.2, where SDN means 'Software-Defined Net profit'

Tuesday 5th of August 2014 08:31:50 PM
Larry Ellison’s Oracle bowled out Solaris 11.2 last week – and what does this Unix-like give us? Cloud computing, yes, but also a stab at a datacenter-in-a-(large)-box. It's not too far off the database-as-a-box idea Larry's been banging on about since 1998. Oracle’s Solaris 11.2 announcement is larded with the usual boilerplate about enterprise scale, efficiency, security and compliance. What's new is a degree of software-defined networking (SDN) support. It’s for that reason that version 11.2 marks the latest chapter in Larry's campaign to turn Oracle’s massive-throughput Exalogic Elastic Cloud appliances into one-stop datacenters.

Nouveau On Oibaf PPA Is Back To Running Well

Upstream Nouveau was unaware of this issue that was affecting my entire assortment of NVIDIA GeForce hardware so it was then quickly assumed to be an issue with the Oibaf PPA that constantly is packaging the latest open-source Linux GPU drivers. On top of mainline Mesa Git, recently there's been the the Gallium3D Direct3D 9 patches (Gallium-Nine). While none of my testing was relying upon the Gallium-Nine D3D9 support, it was wreaking havoc on the system anyhow. As of earlier today some patches were backed out of the Oibaf PPA and since getting back closer to Mesa mainline the Nouveau problems are a matter of the past. With that said, now I'm in the process of running some Nouveau Steam/Source Engine Linux gaming tests similar to today's 20-Way Radeon Comparison With Open-Source Graphics For Steam On Linux Gaming.
