  • Greens 'bewildered' by kerfuffle over Microsoft's Protected cloud status

    The Australian Greens say they are "bewildered" at the way the Australian Signals Directorate has handled Microsoft's application for Protected cloud certification and the subsequent departure of a top female officer from the agency's ranks.

    Protected cloud is the highest security classification for vendors and allows a company to apply for contracts to store top-secret Australian Government data.

    In response to queries from iTWire, Greens' digital communications spokesperson Senator Jordon Steele-John said: "A staffer within the Australian Signals Directorate dared to refuse an application from foreign multinational company, Microsoft.

    "This application ensured secure cloud services receiving protected certification. Approving this certification meant that Microsoft overseas employees could access secure information for government departments.

    [...]

    Microsoft has been allowed to have staff based abroad handle systems on which top-secret data is stored. For the other four Australian companies, only staff vetted by the ASD can administer these systems.

    "It seems that there is one rule for multinational corporations, and another rule for Australian businesses, who are yet to get a look in to providing Protected cloud services to the Australian Public Service," Senator Steele-John said.

    "Australians have a right to know that the corporate interest is not being put ahead of the the security of our data."

  • Container Adoption Starts to Outpace DevOps

    A new survey finds the number of organizations using containers is poised to pass the number of organizations employing DevOps processes in the months ahead. Less clear, however, is the degree to which adoption of containers will force organizations to embrace DevOps.

    The survey of 601 IT decision-makers conducted by ClearPath Strategies on behalf of the Cloud Foundry Foundation (CFF) finds that 32 percent of respondents have adopted containers and are employing DevOps processes. But the number of respondents who plan to adopt or evaluate containers in the next 12 months is 25 percent, while 17 percent are planning to adopt or evaluate DevOps processes. Overall, the survey finds that within the next two years, 72 percent of respondents either already are or expect to be using containers. That compares to 66 percent who say the same for DevOps.

  • Top 10 Reasons Why Desktop Linux Failed

    1) Linux isn't pre-installed - No matter how much we may debate it, having Windows pre-installed on PCs means that's what people are likely to end up using. In order for someone to move over to Linux on the desktop, there must be a clear reason to do so. There is the problem. The only time I've personally seen users make the switch over to Linux from Windows comes down to frustration with Windows or a desire to advance their skills into an IT field.

    My own Linux story, for example, was a mixture of the two examples above. First off, I was just done with Windows. I had already been dabbling with Linux at the time I completely switched, but I become disenfranchised with the Microsoft way of doing things. So for me, the switch to Linux was based out of frustration.

    Had I not experienced any frustrations with Windows, I might not have ever thought to jump ship over to an alternative. Even when I built my own PCs myself, the OS offered at computer stores was Windows only. This is a huge hurdle for Linux adoption on the desktop.

    2) Linux freedom vs convenience - It's been my experience that people expect a user experience that's consistent and convenience. How one defines this depends on the individual user. For some, it's a matter of familiarity or perceived dependability. For more advanced PC users, a consistent convenience may mean a preferred workflow or specific applications.

    The greater takeaway is that when people are aware of other operating systems, they will usually stick with that they've used the longest. This presents a problem when getting people to try Linux. When using a desktop platform for a long time, you develop habits and expectations that don't lend themselves well to change.

  • Optimizing a Python application with C++ code

    I’ve been working lately in a command line application called Bard which is a music manager for your local music collection. Bard does an acoustic fingerprinting of your songs (using acoustid) and stores all song metadata in a sqlite database. With this, you can do queries and find song duplicates easily even if the songs are not correctly tagged. I’ll talk in another post more about Bard and its features, but here I wanted to talk about the algorithm to find song duplicates and how I optimized it to run around 8000 times faster.

    [...]

    An obvious improvement I didn’t do yet was replacing the map with a vector so I don’t have to convert it before each for_each call. Also, vectors allow to reserve space in advance, and since I know the final size the vector will have at the end of the whole algorithm, I changed to code to use reserve wisely.

    This commit gave the last increase of speed, to 7998x, 36680 songs/second and would fully process a music collection of 1000 songs in just 13 seconds..

  • How A KDE Developer Used C++17 & Boost.Python For About A 8,000x Speed-Up

    Open-source developer Antonio Larrosa who contributes to KDE and openSUSE has been developing a command-line music manager called Bard. He's written an interesting post about how he sped up some of his operations by around eight-thousand times faster.

    In particular, Antonio was focused on speeding up the process of finding song/music duplicates in the user's local music collection. What started out as Python code was morphed into optimized C++ code. Little surprise, the C++ code once tuned was immensely faster than Python -- but the blog post is interesting for those curious about the impact of the various steps he took for tuning this implementation.

  • GLib 2.58 Is Looking Good With Portability Improvements, Efficient Process Launching

    The GLib low-level GNOME library while being quite mature is seeing a significant update with its version 2.58 release due out this September for GNOME 3.30.

    Two of the biggest GLib 2.58 changes we have covered up to now on Phoronix has been the new generic reference counting API and more efficient app launching. The reference counting API has been in the works for 6+ years to help GLib's bindings/integration with languages utilizing automatic memory management / garbage collection. The more efficient process launching via the use of posix_nspawn() is also exciting for better performance, particularly on systems suffering from memory pressure.

  • Dolphin-Emu under openSUSE Leap 42.3

    A day after I formally announced my game console emulator repository, the Dolphin Emulator guys decided to merge a patch that makes Qt 5.9 mandatory. That means Dolphin is no longer compatible with openSUSE Leap 42.3 which comes with Qt 5.6.

    I take pride in myself for having a high-quality product, even if it’s just free video game stuff. Therefore my plan is this instead of simply disabling 42.3 and calling it a day:

    I’ll pick the last commit before that patch and build that Dolphin revision. Then I’ll disable the 42.3 target and build the most recent version for the other distributions. That way the last 42.3-compatible binaries stay on the download server until I remove the 42.3 target entirely which will be either when Leap 15.1 gets released or maybe even earlier.

  • GSoC 2018: Coding period (week 4-8)

    Since the last blogpost, the import of JSON files has been significantly improved, now this code is merged into the master branch. Previously, you could import data only from the field of the root object, whose name was specified manually. But then there was implemented the feature to overview the structure of JSON file that lets you import data by selecting an item in the file structure. To implement this, a QTreeView has been added to the ImportFileWidget. To fill it I used QJsonModel, which I and my mentor Alexander Semke improved a little for our needs:we made a display of icons for objects and arrays in the structure, added a display of the root element of the document and more.

How ProPublica Illinois Uses GNU Make to Load 1.4GB of Data Every Day

GNU
Misc

I avoided using GNU Make in my data journalism work for a long time, partly because the documentation was so obtuse that I couldn’t see how Make, one of many extract-transform-load (ETL) processes, could help my day-to-day data reporting. But this year, to build The Money Game, I needed to load 1.4GB of Illinois political contribution and spending data every day, and the ETL process was taking hours, so I gave Make another chance.

Now the same process takes less than 30 minutes.

Here’s how it all works, but if you want to skip directly to the code, we’ve open-sourced it here.

[...]

GNU Make is well-suited to this task. Make’s model is built around describing the output files your ETL process should produce and the operations required to go from a set of original source files to a set of output files.

As with any ETL process, the goal is to preserve your original data, keep operations atomic and provide a simple and repeatable process that can be run over and over.

    I have been meaning to write about my device driver experiments with L4Re, following on from my porting exercises, but that exercise took me along various routes and I haven’t yet got back to documenting all of them. Meanwhile, one thing that did start to bother me was how much space the software was taking up when compiled, linked and ready to deploy.

    Since each of my device drivers is a separate program, and since each one may be linked to various libraries, they each started to contribute substantially to the size of the resulting file – the payload – needing to be transferred to the device. At one point, I had to resize the boot partition on the memory card used by the Letux 400 notebook computer to make the payload fit in the available space.

    The bits touching the xf86-video-amdgpu X.Org driver are for handling RandR lease support. The CRTC/output leases are handled through the modesetting DDX and is for allowing the SteamVR compositor (or other compositors) to have exclusive access to the display/output of the VR HMD without the conventional desktop compositors getting in the way. As part of the xf86-video-amdgpu patches is also the tracking of "non-desktop" properties such as is currently quirked in the kernel for the HTC Vive VR headset so it won't be setup as a conventional desktop output.

  • My First Clang Bug

    Part of the role of being a packager is compiling lots (and lots) of packages. That means compiling lots of code from interesting places and in a variety of styles. In my opinion, being a good packager also means providing feedback to upstream when things are bad. That means filing upstream bugs when possible, and upstreaming patches.

    One of the “exciting” moments in packaging is when tools change. So each and every major CMake update is an exercise in recompiling 2400 or more packages and adjusting bits and pieces. When a software project was last released in 2013, adjusting it to modern tools can become quite a chore (e.g. Squid Report Generator). CMake is excellent for maintaining backwards compatibility, generally accomodating old software with new policies. The most recent 3.12 release candidate had three issues filed from the FreeBSD side, all from fallout with older software.  I consider the hours put into good bug reports, part of being a good citizen of the Free Software world.

A Look At The Windows vs. Linux Scaling Performance Up To 64 Threads With The AMD 2990WX

This past week we looked at the Windows 10 vs. Linux performance for AMD's just-launched Ryzen Threadripper 2990WX and given the interest from that then ran some Windows Server benchmarks to see if the performance of this 64-thread CPU would be more competitive to Linux. From those Windows vs. Linux tests there has been much speculation that the performance disparity is due to Windows scheduler being less optimized for high core/thread count processors and its NUMA awareness being less vetted than the Linux kernel. For getting a better idea, here are benchmarks of Windows Server 2019 preview versus Ubuntu Linux when testing varying thread/core counts for the AMD Threadripper 2990WX. Toggled via the BIOS was SMT as well as various CCX configurations and each step of the way comparing the Windows Server 2019 Build 17733 performance to that of Ubuntu 18.04 LTS with the Linux 4.18 kernel in various multi-threaded benchmarks supported under both operating systems.
