This looks pretty decent in terms of hitting close to the Xeon 2680v4. But every server ARM play so far has been unobtanium until it's grossly out of date.

It's annoying that they provide the mfg of the acoustic model and DAC, but not the headphones which would be required to reproduce or filter the experiment. Most consumer audio equipment is a scam. I'd be interested in the subset

IBM sold an x86 translation for a while https://en.wikipedia.org/wiki/PowerVM_Lx86 . Would be interesting to know why it was discontinued.

Straw man argument, you're looking at around $300/month for 20A, 10+ rack units, 100mbit commit to play with in a lot of decent US facilities. That's a few pathetically provisioned VMs on most clouds. I have such a colo for

FWIW cost for a small biz at most major metro US facilities is closer to $1/mbit for a multi-carrier (which means generally multi-route and high quality with some caveats), and $0.20 if you do something like he.net. For higher volume

I love how they pay people off that have fucked them over. Made the comment thread here about privilege that much more funny.

I guess it's inevitable for dominant companies to become toxic.

Sad to see this downvoted, you make valid points about the importance of bitmapped display being a boon to microcomputers vs character or block oriented systems like minis and mainframes. The reality of modern times is more nuanced and I do

Hard not to come off smug but as a ZFS user it is always jarring to read anecdotes like this in {{ current_year }}.

Ted's post is quite balanced and accurate vs the revisionist fawning in the quoted message from McVoy. But Warner's message elsewhere in the thread is also good http://minnie.tuhs.org/pipermail/tuhs/2017

It would be interesting to see real world impact of health and economy of diesel passenger vehicles in a country like Ireland where most passenger vehicles are diesel vs the US where very few are. Commercial vehicles are going to push far m

Note that in most cases TCP congestion control only really matters from the sender side. Windows has a fairly nice algorithm called Compound TCP if you are sending from Windows https://en.wikipedia.org/wiki/Compound_TC

Your terminology seems a bit strange to me, the way I've seen these discussed: CoDel is an AQM (Active Queue Management) algorithm - it decides what packets to drop and when to drop them as a packet queue fills. This is most relevant

nginx is nearly optimal for content serving (see Netflix presentations) and TLS origination or termination. It's actually somewhat weak in the features they charge for.

Intel's QuickAssist is about to be standard on Xeon E5 chipsets and can do very high scale gzip at the cost of a PCIe round trip. Intel published some patches to ZoL for this.

That's not really accurate phrasing, Sun had no involvement in OpenZFS because it started after Sun no longer existed. Sun maintained OpenSolaris which served as the de facto implementation of ZFS. OpenZFS was started in response to

Storage devices regularly go berserk in really novel and interesting ways when you have a large enough pool. Most projects I've worked on, I've known enough to fix the bugs, had a working theory of what the issues were and could

Think about what this _means_, and let's be really conservative and assume a huge splay of 10 year old to current hw: 8 million cores, 10 million storage devices (100-1000x IOPS, 1-10x TB capacity), 8x recent global IP transit rate wi

I think this is somewhat well understood in things like Sports Psychology. You don't tell a receiver to catch X number of throws per game, you just encourage them perform. Likewise, training that more accurately simulates performance

This is death throes of imgtec.. and as a side effect, put a fork in MIPS, it's done.

If you are trying to solve multitenancy, SmartOS makes this a non-issue by securely virtualizing Linux syscalls instead of virtualizing an entire computer like VMs.

They have one that is two PCIe3 x16 connections from one ASIC right now, it uses a ribbon cable :). That's janky, but it does work on currently available platforms. I've heard Mellanox will do a CAPI NIC, which is quite tantaliz

See drewg's comment. He is being modest in that they are also doing CPU encryption at 100G, so every single stream is different which doubles the usage of memory bandwidth. I will get to 100G with Skylake, mainly because we have to re

It's kind of the other way around, TCP is done in silicon and firmware and passed up to the OS via a scatter-gather engine which is the core architectural feature. So iWARP lends itself to layering on the TOE, as do other higher level
