Arm servers are on Nutanix's long-range radar, not yet its to-do list

botfap

Not really. While ARM has started to make a small imprint into customer workloads on Amazon and Oracle clouds its still very much of a niche market. In terms of corporate maket share (Nutanix target customers) ARM is still zero or a rounding error at best. There are no tier 1 vendors selling ARM Equipment into the channel yet

I would love to see readily available ARM kit but right now it doesnt exist in volume. We actually run some ARM kit in production but its very low volume kit from specialist OEM and the support is poor

Re: Who would voluntarily deal with this company

Its never cheaper to move them into Azure cloud. Either you are a lazy boy or you haven't done your sums properly. In no way, shape or form is it cheaper to run Oracle services on Azure than it is on prem, even for a tiny number of servers (8 as you say). Even if you needed a single dedicated staff member for them, its still not cheaper

Azure is roughly 3X the cost of Oracles own cloud services, even Oracles services that run inside Azure. Ive done the maths on this for tens of clients. Never in a single instance did it make financial sense to move on prem Oracle services to Azure

Re: Ampere machine

Yeah they are pretty good value. It doesnt show it on that page but there are 128 core variants available now. We bought 5 more in February and the 128 core / 192GB RAM variant was a little over £3600 (ex-vat) per unit with the 4x10GB network upgrades. About the same as high end gaming rig or top specced Apple laptop with 12 cores. Of course grpahics is handled by the BMC and they are terrible but fine for development work as long as you are not doing 3D stuff but you can add pretty much any consumer or professional AMD or NVidia card if you need that

You can but single unit quantities of the 32-128 core variants from i-Pi for not much more:

He was previously using Apple devices for the ARM side but Im fairly certain that he would have been offered an Ampere Developer Platform Desktop. Even we got one of them and we are just a smallish sized dev house doing mainly embedded and optimised cloud images

These are the systems they were giving out, which anyone can also buy:

Re: cheeky appeal for advice

Harsh but mainly fair. You are correct in that its not just ASUS. Ive seen the same lazy stupidity with HP, Lenovo and pretty much every OEM. Even with Laptops that are sold as "Linux" laptops, especially from Dell

The linux side DSDT situation is actually quite good now. You can still dump, modify and recompile the DSDT. The live DSDT lives at /proc/acpi/dsdt or /sys/firmware/acpi/tables/DSDT. You can decompile, edit and recompile with iasl which is a standard tool in all distros Ive seen

None of that however helps a non technical user. Its a pretty simple process to dump, edit and re-create a DSDT if someone else has figured out the missing bit. However figuring out how to fix the DSDT itself can be a pretty daunting process, even for seasoned developers, if you dont have good references and documentation which the OEM's just dont provide

Re: cheeky appeal for advice

I have the same with the 13900H CPU variant that I use as my travelling device. If its the latest model (UX6404) then you can fix it by adding a quirk definition into Linux Mints 6.5 kernel config and rebuilding the CSC3551 module. Its simple enough but can feel a bit of a palava if you have never done it before

Full details here: https://github.com/rykdesjardins/fix-UX6404VI-audio-linux

The cause of the problem is not actually a kernel issue. Its a badly developed BIOS from ASUS which is missing parts of the ACPI/DSDT table. The kernel quirk just works around the ASUS error. Hopefully it will be fixed in a future ASUS BIOS update however this same problem is quite common on a lot of recent ASUS laptops

GNOME 45 formalizes extensions module system

Re: Perhaps GNOME could...

Long term Mint Cinnamon user here. Ive used it exclusively on my laptop, gaming desktop and workstation for the last 5-6 years because its been rock solid stable and the UI has been uncluttered, straightforward and consistent. Its also the standard desktop within my company. However its dependency on Gnome apps is getting worse rather than better, the UI is becoming messy and inconsistent, default themes are a mess and we have had quite a lot of stability issues with v20 onwards. A lot of the default apps now use Gnomes libadwaita for themeing instead of standard GTK themes and look out of place and have different behaviour. Desktop stability has also been a problem since 20.3 with crashes on unlock desktop and coming out of sleep, sound and video stuttering issues across a wide range of dektop and laptop hardware and desktop responsiveness is a bit more sluggish than it used to be. They have also basically said point blank that they have no interest in supporting wayland so Cinnamon is looking like a dead end moving forward. Add to that the refusal to even consider an ARM64 spin even though ARM desktop hardware is now becoming more common

Its not horrific and not bad enough yet to be planning a change, its too much effort right now for a whole fleet of PC's. I do however have this nagging doubt going forward about what they are currently doing and focusing on. Its a shame they dropped their KDE spin because thats probably what I will be looking at next. Gnome 4x is almost universally hated by our devs and users and most of them consider a default install unusable without at least dash2dock or dash2panel extensions. Sadly those extensions have a habit of breaking, even with minor, distro packaged updated

InfluxData apologizes for deleting cloud regions without performing 'scream test'

botfap

Re: "Your number one expectation as a cloud database provider is to keep data safe and recoverable."

>What guarantees do the Cloud providers give for data recoverability and integrity.

None whatsoever. Ive been through this with clients who have lost data and servers from cloud providers (Azure & AWS) and VPS providers (Vultr, IONOS, HeartInternet and others). Even when you replicate data to multiple zones a stray deletion command in one zone replicates to the others before you can finish your brew and investigate. The contracts are always water tight on the providers side, there is no comeback or compensation when it happens

As an earlier poster remarked: There is no cloud, its a mental abstraction, only other peoples servers. If you are not doing your own, locally stored backups and replicas then you are asking for a disaster. The cloud isnt some magic place where data is secure. Its just a marketing abstraction to make you believe thats the case. Its also fucking expensive compared to running your own, even on a small scale, unless you are in a location where appropriate bandwidth isnt available. In which case you probably chose the wrong location to base your data intensive business

Ampere heads off Intel, AMD's cloud-optimized CPUs with a 192-core Arm chip

botfap

I would second this if you want or need some ARM hardware for testing your software on. What they offer is exceptional for free and Im not quite sure how they are affording to do it. Ive played with the free Oracle instances and performance was fine, pretty good even. Disk IO was heavily limited (think SATA2 HD) but CPU and mem performance was surprisingly good

Just be careful with the egress limits, they can quickly start turning into billable megabytes if you use them regularly

botfap

Re: How much overbooking can that CPU take?

You are quite right. The Ampere CPU's dont respond to over provisioning cores quite as well as the x84_64 stuff though, due to lack of SMT I presume. For mixed, low priority workloads on Epyc we will provision 300% of the cores, on Ampere 180% seems to be the sweet spot for us

Docker security is not amazing and while it has improved over the years there are still many fundamental gaping holes in its architecture. You would be a fool to use docker alone it a multi tenant architecture without additionally separating each tenant with VMs

Take this little beauty from 2014 for example. Closed but not fixed due to lack of upstream support: https://github.com/moby/moby/issues/6324

And its proposed solution from 2016, which is still open for the same reasons: https://github.com/moby/moby/issues/24716

Its very hard to get the docker guys / gals / traps to accept a security related submission, Ive tried many times

This is just avoidance and deflection. Your response has nothing to do with the point that I made and is further self delusion to justify censoring opinions that differ to your own

Deal with the point I actually made:

>you should tolerate all speech, but by doing so, you are promoting hate speech

This is a completely false dichotomy and its present in the thought process of extremists on both the left and right. In no way, shape or form is tolerance the same as promoting, its not even in the same ball park. You are being very dishonest here. Either intentionally or because you dont have the self awareness to see your own contradictions

This is why censorship is so dangerous, especially around "hate speech" which has no clear definition. Ask 10 different people what qualifies as "hate speech" and you get 10 different answers. Thats why we created our cultures around free speech with a very specific exception of incitement to violence. Anytime you go further than that its for censoring opinions that differ from your own, regardless of the lies you tell yourself to justify it

Re: Dodged this bullet!

They probably earn more than that now. Ive been out of the Blue Chip world (mostly) since 2006. Before I decided I hated working with "Blue Chip" companies, I was doing SAP integration contracting in the late 90s through to the mid 2000s I was getting £1200-1500 / day depending on the client (big pharma paid the best) and I would get mileage, hotels and expenses on top of that. I was only mid level and there were better skilled people earning upto £2500 / day. The rates were so disconnected from knowledge and expertise that it almost felt like theft at the time. It wasnt even particularly complicated compared to the embedded development world Im in now. The hardest parts of dealing with any SAP deployment are the politics first, then dealing with the fact that the sales team sold something that didnt or only partially existed

Re: ASML

DongFang is now also developing EUV thanks to info stolen from ASML. It doesnt have access to the latest ASML IP but it did have a lot of people inside ASML until mid 2021

botfap

Re: ASML

Yes they used EUV in a small part of the process but it wasnt the complete process as originally planned. Its still a DUV node with 3 layers processed with EUV

botfap

Re: ASML

TSMC's 7nm nodes (N7/N6) are not EUV, they are the last of TSMC's planned nodes built on the DUV process. TSMC didnt use EUV in production until the N5 nodes. Originally N6 was supposed to be on an EUV process but TSMC couldnt make it work in time and stuck to DUV for those nodes. There is a 7nm class TSMC node built on EUV called N7+ but that came after N5 was released

SMIC / DongFang's N7 process is also DUV and is based heavily on TSMC's DUV tech. It was basically stolen from TSMC. DongFang also managed to get most of the info needed to reproduce TSMC's EUV process and most of the info needed to reproduce ASML litho tech but they are still a couple of years out from making that a high volume production process

botfap

Re: Capmmunism

Completely agree. However we have gone too far in the opposite direction. Critical infrastructure like this SHOULD be invested in by the state for the good of our own economies. Our own governments in the west have watched this bottleneck approach for at least 10 years and done nothing to make the ecosystem more healthy and robust. Consequently we now have a defacto monopoly on advanced chip production in the west and the skyrocking wafer prices that go along with such monopolies

botfap

Re: ASML

This is no longer true. Chinese company DongFang is making their own lithography equipment now (even if it probably is with IP stolen form ASML). While its still a few years behind ASML they are catching up quite fast. So much so that a few months ago SMIC started volume production of a new 7nm node based on DongFang equipment that is functionally the equivalent of TSMC's 7nm process. Not quite as refined yet but they will get there because they are putting the investment in. They have 5nm EUV nodes planned for Q4 2023 and 3nm nodes planned for late 2025. Thats probably optimistic timing but they will get there eventually

We have been lazy in the west about this stuff, relying on a single company instead of creating a robust ecosystem. We assumed we were so far ahead that nobody else would ever catch up. The tortoise and the hare race with China has played out tens of times over the last 2 decades and the tortoise has always eventually come out on top because they actually invest and do, rather than embargo and sabre rattle

Re: Mint 21.1

Im in the same boat, old eyes that need decent contrast. Modern themes are all too uniformly dark or light for me, I want something in between

I agree, the Mint default, medium grey on dark grey is hideous. The new themes (from 20.2) give me eyestrain on the light themes and take me too much effort to pick out individual elements on the dark themes. Same is true in Gnome 3 and KDE 5, though KDE is a bit better in that regard

I always end up using the mint-legacy-themes and papirus icons as they are a nice blend of dark and light and my eyes can pick out the elements immediately so I end up with this:

Just tested CubeIDE on 21.1 and it works fine here. I installed CubeIDE on Mint 20 and its still fine after upgrading. A cheat way of setting up the 32 bit multiarch and libs on Mint or Ubuntu is to just install "apt install steam", that will setup multiarch for i386 and install all the base libs

Mint 21.1

Just upgraded my laptop to Mint 21.1 this morning. Ill give it a couple of weeks before I do the workstation upgrade just to be on the safe side. No problems and everything went smoothly, but my god, the new default theme and colour scheme is ugly. Its like the old Redhat 7/8 theme from 2000-2002. I dont know why Mint have switched away from the distinctive green themes to something so bland, generic and blue

Everything works well though. The desktop is a little more responsive on the cinnamon version and the new animations are much more subtle. Was only a 30 second job to install the mint legacy themes and papirus icons and its backing to looking good too

Olive is great

Olive 0.1.2 branch is an excellent, simple(ish) video editor with some great community created effects and very good performance. I use it frequently to create training videos and its rock solid stable. Its an ideal first time video editor for new users with a simple interface and a suprising amount of features. Only problem is there are no binary packages for it and you have to compile from source which most users are not going to do. The new olive 0.2.x branch is still a bit of a mess. Its getting there very slowly and hopefully will be ready for production use soon but its very buggy for me with frequent crashes and incomplete features

I ended up creating my own fork of 0.1.2 with a few fixes and baked in community themes which I will keep using till the 0.2.x branch reaches stability

Re: Windows S store has been charging for some time

botfap

Re: Windows S store has been charging for some time

Its free now but when Windows S first hit the OEM channel in 2017 it was different. S was initially considered a separate, cheaper release of 10 and if you wanted to "upgrade" from S to Home or Pro then you had to buy an appropriate upgrade license. An upgrade to Home from S was £49/$49/€49 and an upgrade to Pro was £119/$119/€119. It stayed this way until mid 2020 when Microsoft had a change of heart and folded the S edition into a mode of Windows Home. This was mainly because most OEMs were getting pissy about having to support Windows S which didnt behave in the ways their support teams were used to. OEMs didnt want S, they just wanted Windows

Re: Im surprised they are bothering with this...

In simple core terms we span from 16-80 cores per node. We have 39 "servers" in total with 8 of them being hot standby (one for each type of deployed hardware). Our oldest hardware is dual socket, Haswell era Xeons (E5-2675 v3 iirc), 2 x 16 cores. We have a couple of slightly newer gen, single socket, 20 core Xeon 6138Ps. Our latest and greatest are single socket EPYC 7713P's, 64 core, very good value and performance. We also have some prior gen 32 core EPYC's which were our first introduction into AMD servers. Our primary build farm is made up from 12 x Threadripper 3990X 64 core, self built boxes. Not server CPU's of course but they provide better performance and lower cost than the equivalent EPYC's thanks to them being commodity hardware and having higher clock speeds (though its a product line that seems to have been cancelled now). Our ARM build servers are Solidrun LX2 Honeycomb boxes, 2 x separate 16 core servers in a single 1U chassis. We are currently evaluating a Gigabyte Ampere Altra Q80-30 80 core ARM server which is a huge step up in ARM performance but Im not convinced about value yet

As you can see, its a very mixed non enterprise topology hardware wise and we are far from enterprise level budget wise! We try to reuse wherever possible. Our infrastructure is split into 5 main regions; internal admin, build farm (X86+ARM), client build services, CI testing and storage. Each of these have different performance characteristic requirements

-For example our entire internal admin systems (sales, support, finance and admin) and its 9 VM's can run comfortably on a single EPYC 7713P 64 core box. We spread them over 2 with automatic fail over but they can all run on a single box should there be a hardware failure

-Our internal build systems need as many cores as possible at as high speed as possible but dont use a lot of RAM comparatively speaking so Threadripper 3990X's fit the bill perfectly here. On the ARM side the LX2 was the only commercially available option at the time

-Client build services are a mixture of 64 and 32 core EPYC's split over 2 generations. CPU performance isnt as critical as our internal build systems (I pay my own staff, not clients!) and the RAM requirements are much higher than you can pack into 3XXX Threadripper. We basically over provision the CPU cores because most of these jobs are submitted for overnight building, ready for the next day

-CI is a hodgepodge of repurposed, old build servers from Intel and AMD of various core sizes. Performance isnt critical here and in a push we can steal some cycles from the build farm

-Storage is done on the old Haswell era Xeons

I have no issue with VMWare from a technical point of view. Its definitely the most noob friendly ecosystem and its solid and reliable in the most. Its the constant redefining of the product into multiple, chargeable SKU's and the corresponding invoices that I had to pay that pissed me off. If Im the IT director at a bank then Im playing it safe and I would go VMWare, its off the shelf with an abundance of certified bods but has a price tag to match it. I dont care about the price in that situation. As a small to medium sized dev house I need better value, much better value. I also need stability, I dont have the resources to constantly throw at the upgrade cycle

I never looked at oVirt, it didnt come up on our radar at the time, Im not sure it was in any usable state then. [Java rant redacted]. We did briefly look at Proxmox but ruled it out quickly due to it being a bit of a mess at the time and a lack of support on ARM hardware. We were already in the process of deploying some test ARM kit and wanted to make sure that if we deployed production ARM64 servers in the future then we didnt need to change our infrastructure to deal with it. Proxmox is basically KVM (with LXC in later editions) anyway so there were no real advantages there, only negatives. Proxmox still doesnt have ARM support and we now deploy ARM64 based servers both internally and for clients

We also looked at pure open source XEN server, which was a little ahead of the feature set of KVM at the time. But with KVM being accepted into the Linux kernel as an official component, the writing was on the wall as to which open source virt layer was going to get the lions share of quality developer time in the future so I bet on KVM and it seems to have been the correct play so far
