So I'm an email guy from way back... Literally decades...

Nobody leaves ports 110 & 143 open & exposed anymore. Not just blocked by a firewall rule, the Dovecot daemon's themselves, properly configured, simply don't listen on non-secure ports anymore at all. It's dead technology. You get bit by this, you're just an idiot.

What I found amusing is the bit about modern Outlook vs. Legacy. Modern Outlook, even on your desktop, is a cloud play. You might think you have a local App. You don't. Modern Outlook can't handle a simple "Linux" username as an account. The user "bob@example.com" represented by a "bob" entry in /etc/password cannot be used by a modern Outlook client. It passes the domain to M$ cloud and converts it to "bob@example.com", which a local vanity Dovecot domain will reject. It's intentional... They have placed their cloud between your local App and the email server. You think you're running a local app, but they're hoovering up all your email in a proxy config.

Blah. I went to see it on Thursday and while the action scenes and the cinematography we top-notch as expected, there was no story. I wasn't invested at all in anyone in the movie (well, Grogu because he's so damn cute). Sigourney Weaver was wasted in the movie. Though watching Hutts wrestle was kind of amusing, there was nothing for me to invest in. Granted, it was better than episode VIII, but that is a pretty low bar. Rogue One was a much better story - even though once you knew they were stealing the plans to the Death Star you knew where the story would go after, but how they got to the end...

I actually followed one of these yesterday about 10 miles north of the Gigafactory. No branding, odd shape, weird dull gold. The rear tires are large enough to fit a full size SUV. I almost pulled out in front of it because it was lumbering along below speed limit. But the WTF factor got me and I ended up stuck behind it.

Next time there will be QA testing...

Clustered FS and Objectstore are built on top of SAS, FCOE, iSCSI, NVMe-OF. You first have to solve the problem of packing thousands of storage devices within the signal integrity radius of the transport medium before you can start abstracting. For NVMe that radius is about 1.5 - 2 meters from the CPU socket. SAS about 5 meters. Not sure on FC, I presume a couple km.

Completely common. Like 70% of all servers sold include a RAID controller that can talk to NVMe devices. But there's a catch... They suck so badly, nobody buys the PCIe cables to connect the backplanes. The inside joke is the best way to slow down your NVMe drives is to attach them to a RAID controller. Most NVMe drives use 4 PCIe lanes. Broadcom's RAID chips let them have two lanes. Then the RAID controller connects to the CPU with 16 lanes. So the minute you exceed 8 drives (via a switched backplane), you have an intractable bottleneck.

The Broadcom 3xxx chip hit the wall first as it still did RAID partially on the controller CPU. The 4116 implemented RAID entirely in silicon, the 51xx chips took this further with a complete cache redesign, and actually ditches SAS/SATA entirely. It's NVMe only. But nobody has solved the PCIe lane bottleneck.

Via a PCIe switch backplane. They've been around for a while... Perhaps as far back as 2012...

I fully expect SAS4 to be the end... NVMe-OF will replace SAS, and the drives will plug into the crazy 800GbE switches that are available now. Not on the drawing board... Now.

It's dead, Jim.

It's not coming back.

I got my hands on a 3B1 around 1990. Linux wasn't available of course, and a used Sun was just out of my reach. It was a giant box of suck. The most corporate version of Unix I've ever used. It made me pine away for the dialup guest account on Compupro's Unix Version 7 system in the east SF Bay back in the 80's...

Eventually I picked up a Sun 3/50, and later a 3/60. Then some kid in Finland posted on Usenet and well...

The whole point of Wordpress is so you can host your own site and not have to have your web site held hostage by one of the oligarch-controlled cloud providers!

No thanks. Good Bye!

Funding via pay per view? There's an Idiocracy joke in there somewhere...

I'm about done with NVIDIA. Here's to hoping Intel improves their Linux driver support... They step up their game, and I could be convinced to switch. But right now.... It's all crap.

Kevin Rose killed digg. He took what was good and ruined it.

Reddit embodied what was good about Digg and ran away with the market share.

As long as Reddit doesn't fuck with their algo, and try to pull a "Kevin Rose" (not unlike what Tik Tok just did) it will be ok.

Fuck digg, and fuck Kevin. Go back to making videos where you pretend you're "edgy" because you have a 40oz in a brown paper bag.

Kevin and his idiot people killed Digg a long time ago when they implemented their own algo to determine what users could see and corrupted it with a bunch of advertising. It should have been left alone. Nobody cares and nobody wants it back.

So? How much single threaded rendering does anyone actually do?

I understand why in some cases single threaded performance is important, but not for the vast majority of use cases.

I don't actually know. My desktop runs Linux. I patch it a couple times a month perhaps, and grab a cup of coffee while it reboots.

But to the point of "Why hasn't it gotten faster", you have to understand what its doing. Servers have entire subsystems to inventory & boot, a modern Dell server has at least 3 OS'es (4 if you have an expander backplane) hiding under the hood before the one you see boots. So servers have a bit more stuff. But the fundamentals are the same for desktops & laptops. RAM and DDR training. Yes, PC's have gotten a lot faster. RAM has gotten a lot bigger, and more to the point we keep juicing more speed out of it. Getting DDR5 to hold on to the bus and emit a usable signal at 4800Mhz with signal integrity to travel 1 meter to the socket take a little bit of tuning.

Enjoy the cup of coffee.
