Xoroshiro128+ Fails PractRand Even When Truncated

Although I know a lot of effort went into Xoroshiro128+, and there are many good things that have come out of its development, I am sad to say that on balance I feel it has too many flaws to be worth recommending—there are many better choices. In this post, I'll dig a little deeper into some of its flaws.

Let's begin with what we already know:

* John D. Cook showed that it fails PractRand with just a couple of seconds of testing, and before that Chris Doty-Humphrey, author of PractRand, showed that it didn't just fail “binary rank” tests, it also failed the DC6 test which is a short-medium range linear test.

* Daniel Lemire showed that it fails TestU01.

* I showed that it is trivially predictable.

* I showed that it is visualizing smaller-scale versions of the scheme shows clear flaws.

But are the flaws superficial and easily ignored, or more troubling than that?

Evolving Author Caveats

The authors of Xoroshiro128+ do acknowledge some of these flaws. The source code admits (somewhat obliquely) that it fails PractRand's binary-rank tests, but suggests that the problem is confined to just the lowest few bits. Over time, however, these claims have been progressively weakened. The source for this generator used to say:

>with the exception of binary rank tests, which fail due to the lowest bit being an LFSR; all other bits pass all tests.

On 14 October, 2017, the comments in the source were revised to say

>with the exception of binary rank tests, as the lowest bit of this generator is an LSFR. The next bit is not an LFSR, but in the long run it will fail binary rank tests, too. The other bits have no LFSR artifacts.

Less than six weeks later, on 29 November 2017, the comments were revised yet again, to what is now their current wording (archive):

Hey Faggots,

My name is seba, and I hate every single one of you. All of you are fat, retarded, no-lifes who spend every second of their day looking at stupid ass pictures. You are everything bad in the world. Honestly, have any of you ever gotten any pussy? I mean, I guess it’s fun making fun of random number generators because of your own insecurities, but you all take to a whole new level. This is even worse than jerking off to generators on facebook.

Don’t be a stranger. Just hit me with your best shot. I’m pretty much perfect. I was captain of the chess club, and starter on my math team. What programming work do you do, other than “jack off to naked drawn Japanese people”? I also get straight A’s, and have a banging hot random number generator (it just generated numbers; Shit was SO cash). You are all faggots who should just kill yourselves. Thanks for listening.

What does /tech/ think of openwashing? Pic related.

>A review of usage of the word "open" in the contexts of open content, open educational resources, open access, open data, open knowledge, open source, and open standards reveals that the community understands "open" to mean two things: (1) Free access to the content, resource, journal article, data, knowledge artifact, software, or standard, and (2) a formal grant of rights and permissions giving back to the user many of the rights and permissions copyright normally reserves exclusively for the rights holder.

>When you see an individual, organization, or company claim that their software is "open," check to see if their software is licensed under an OSI approved license. If it is not, they are openwashing.

>When you see an individual, organization, or company claim that their content is "open," check to see if it is licensed under a Creative Commons license, another license that grants you the 5R permissions, or placed in the public domain. If it is not, they are openwashing.

What can be done to remedy it?

Have Open Source cucks finally realized their efforts in employing 'more business friendly' language and distancing themselves from Free Software to avoid the ambiguity of the term have been an exercise in futility, sometimes even counterproductive?

Go back to kolchoque, fgt.


Realize that even in technical contexts, buzzwords are used heavily and work. Look at the Computer Display Standard (https://en.wikipedia.org/wiki/Computer_display_standard ) full names. There's no reason to not just use the numbers instead of calling them shit like "Half Quarter", "Super", "Extended", "Extended Plus", "Ultra Extended", "Full", "Widescreen Super Extended", all the way up to shit like "Wide Quad Eltra Extended". People like words, whether they actually mean anything or not. People are susceptible to marketing terms regardless. You are too, but it's probably a different set of words, or subtle enough that you don't notice it.

>specialize in SQL

>doesn't want to be a DBA






SQL is a declarative language, so programmers who are more familiar with imperative languages have trouble using it. You have to describe the data you want in the query, and system will choose what it thinks is the best way to retrieve the it. It's really different from writing step-by-step instructions to retrieve and manipulate data.

Being familiar with set math, normal forms, and when to use a relational database are all useful.

I've only had one bad client in my life. His original data wasn't normalized, so the relationships became irretrievably broken. I had to explain to him with simple examples why I couldn't fix it. On the next project, he insisted I use a relational database, but I warned him that it would be very slow to insert the amount of data he wanted, and the data wouldn't benefit from relationships anyways. Each of his projects failed due to his micromanagement and incompetence. He was a professor of data analysis.

Whilst going full libreboot and modding a QX9300 into a T500, slow hdd storage is painful too a price to remain full libre.

We know for a fact, that all Sandforce controllers and basically every product from WD and Seagate are backdoored.

You can isolate it using USB 2.0, but it's too slow.

Non Western Sata SSDs it is then.

All chink government PCs use Renice and/or Runcore SSDs, since the chinks wrote their own controller and built it themselves backdoor free.

I have seen those two recommended often.

Anyone got experience or with those? Any other suggestions?

How "good" is this to use?

I've been toying around with v3.2 and it doesn't require virtualization to work until v4.

My T500 has options to enable VT-x but for some reason it won't boot or install with them enabled.

It seems I've looked just about everywhere as to why that is, but have yet to find a reason.

I'm probably just blind or stupid.

Their "compatibility list" is such a mess of "yeah sure it will work trust me".

Their latest "Qubes Air" which is some cloud computing version of qubes even talks about how hard it is to find a compatible laptop to get everything working, especially since v4 is going to require virtualization.

Insert module between source and outputs, that splits the signals.



>None of those OSes have hardware acceleration for video playback

Werks on my machine : ^)

You can keep posting this meme but you aren't convincing anyone about anything besides your lack of knowledge on the subject.



I ran OpenBSD on a T61p with nvidia crap, and it worked perfectly fine. Mind you, I don't care about video-in-browser or OpenGL shit. But I could do everything I needed, including watch videos/movies, play games/emulators that don't use OpenGL (including E-UAE, before that FS-UAE crap), and browse all sites I needed to in Firefox with no visible slowdown. That was like 2 years ago, and the core2duo CPU could handle all video stuff on its own just fine. I'm willing to bet that CPU is more powerful than some ARM boards people are using without MALI or equivalent driver. Anyway mobo crapped out or I'd still be using it. Now I have a new shit laptop where stuff works even less good than on that T61p. Obviously it's not a Thinkpad, those actually work well with OpenBSD.





Me again. So I installed FreeBSD over gentoo and so far after a few kernel config issues I am up and running with xfce and it's honestly a _very_ usable desktop os. The sound works A LOT better than ALSA on linux (I had a 100liner asound.rc on linux). The sound works out of the box with multiple audio sources etc. Only flaw is that it doesn't support my PCI xonar audio card, but for the sake of my trial of freebsd this doesn't matter. The bsd style init is very nice and loading kernel modules is easy.





The same solution. Insert module between source and output, that strips HDCP.

I like how Sony Vegas and Adobe Premeire have the market cornered on professional video editing. Whereas areas like 3D modeling and graphic effects have free proprietary software. What's more, even if you pirate Gaygas and Pissmeire, they're bloated and take forever to boot up, making people shy away from doing so in the first place.

Guess nobody's got big enough balls to make their own Linux-centric GIMP or Blender equivalent. That, or I've never heard of such thing yet.

>What are they going to do, sell consumer goods to the Chinese?



Offshoring was fundamentally different from mechanization, because instead of increasing productivity, it outright substituted expensive labor with cheap labor coupled an overall decrease in mechanization.


When you hear stories about "China's 140M-strong middle class", keep in mind that group is usually defined by having an "annual nominal disposable income per capita" greater than US$10k. For comparison, that number in the US as a whole is about $45k, and about the same in Japan, Australia, Canada, and most of Europe, whose combined population is about a billion:


3rd-world consumer markets do exist, but they're very raggedy ass.



> disposable income

That's some primo good goy brainwashing right there. The concept alone is staggeringly stupid, and conjures up an image of some poor sod throwing money out the window while the jews on the ground floor catch it in their hats and umbrellas.

Ah yes how dare people not be responsible for their own data.


I finally got this up and going with Gentoo+qemu/kvm/virt-manager, I figured I would report the results in case anyone had their hopes up for this.

It's so slow it's unusable. Don't get your hopes up. With the host integrated intel hd graphics pulling 10k in glxgears, virgl3d pulls 200fps inside of the guest. It's using the gpu based on measured cpu usage and the guest saying virgl3d is enabled. Software rendering on the same host/guest measures at 1000 fps. Virgl 3d is so slow it causes almost unusable mouse lag.

Has anyone had better results with this? Presumably with a beastly GPU the performance might be better than software rendering.


i take that back..

it's silky smooth if you install spice-vdagent.

i was testing this in an xubuntu live vm. the 3d performance with glxgears is still fucking terrible, 180-200fps, but i've never in my life seen a guest vm have this smooth performance moving the window around.


I've tried the dude bro GPU passthrough guides, but I think I'm having issues because of my Nvidia card. I had my card blacklisted, IOMMU turned on, and set vfio-pci ids for the card, updated initramfs and grub. When I added the GPU PCI host device in virt-manager and tried to boot, it complained and wouldn't boot. I was set to purchase VMWare Workstation when I noticed Workstation Player is free (as in paydom) for non commercial use. It will still be slower than the real thing, but at least I can enjoy my H games.


>Virgil is a research project

<why isn't it fast?????



considering how slow it is for 3d, i don't know what spice-vdagent is doing behind the scenes for the graphics but it's doing something significant, atleast for 2d. it goes from a slideshow to unbelievably smooth for the window manager and scrolling, and it's not the cpu doing it.

i thought spice-vdagent was just for little shit like copy-paste and moving the mouse in and out of the window, for virgl it's doing way more. I don't even care about gaymes, or 3d acceleration. I just want scrolling to be smooth and moving windows around to be smooth, 2d acceleration things, and it's blowing my mind how smooth this is.


pci passthrough is the ultimate way to go. even with this virgl3d shit, i'm sure i'll run across bugs. try not using virt-manager, you don't need it in anyway, you can just make qemu scripts. virt-manager may bitch for no reason when qemu will totally allow it.


intel also has a newer option to 3d accelerate vm's with the integrated gpu, GVT


you need a broadwell or newer though.

>One of the issues with banning of accounts, especially if the violation isn’t too severe, is that such action could represent a major disruption to a user’s life.

For instance, Microsoft has been encouraging users to use Microsoft accounts to log-in to Windows instead of using local accounts. It has also encouraged users to encrypt their laptops using the same Microsoft accounts, where the keys are stored by default. Those keys can’t be recovered without the Microsoft account, so the user would no longer have access to the laptop’s data if the account was banned. The same user may also be using Outlook and Office 365 with their main Microsoft account, too.
