rob-olmos··on Hardware microphone disconnect (2021)
Another annoying mic feature was older macbooks (before T2 I think) didn't have any built-in way to plug in the 3.5mm jack for a mic, and the usual sound output still be the internal speakers. Or an easy way to set the mic to monitor mode like in Windows.
rob-olmos··on HelloSystem – OS with original Mac philosophy with a modern architecture
Relatedly I wish Mac's "mission control" and "app expose" was better, becomes difficult to find frequently used windows.. seems to place windows in random places. It'd be nice if it made it easier to see browser tabs.

I liked the the UI/UX of David Gelernter's "Scopeware" layer, that seemed like it would be a nice alternative to either of those.

rob-olmos··on New Mac Mini
FYI Chrome is trialing that feature natively titled "Memory Saver". It's available in my laptop's settings, but currently still not in my desktop's.
rob-olmos··on Notes on ExFAT and Reliability (2021)
I think you were referring to this part with "errors creeping in", such as the Usenet storage servers probably using cheap/old drives & controllers with bit-rot & bit-flips before it got to the TCP/IP stack.

Probably also using cheap/old network equipment too that would bit-flip between when the TCP/IP checksum was recalculated. And like you said, combined with the re-publishing of corrupted files if they didn't bother to par2 correct them first (ie., human errors creeping in :)

rob-olmos··on U.S. bans equipment from Huawei and ZTE, citing national security concerns
I believe they're referring to 802.11bf "WLAN sensing"
rob-olmos··on Researchers quietly cracked Zeppelin ransomware keys
> “The challenge was that they delete the [public key] once the files are fully encrypted. Memory analysis gave us about a 5-minute window after files were encrypted to retrieve this public key.”

> Unit 221B ultimately built a “Live CD” version of Linux that victims could run on infected systems to extract that RSA-512 key.

I'm guessing most didn't make it within the 5-min window, so the Live CD would recover the "deleted" record from the Windows Registry database?

rob-olmos··on Thirteen Years of Go
What sticks out most for the Java code being pretty awful? Was the PHP code just as awful too in similar aspects?
rob-olmos··on Silicon innovation and custom ASICs at Amazon [pdf]
What's the next circle going to be? Mainframes become even more specialized & powerful, and then the cloud builds new more specialized silicon to match it?
rob-olmos··on Sudo: Heap-based overflow with small passwords
Yea I sometimes have to refresh my memory on sudoers or just search for what I want to accomplish, hoping that someone has already handled the potential security gotchas (eg, exact fullpath command should always be specified).

I agree, in some typical cases I only need to specify "<user> can become root" or "<user> can become <user of group>", kinda like doas already does I think.

I'll probably try out doas when the next such special need arises, then resort to sudo if doas is insufficient for some reason.

rob-olmos··on Sudo: Heap-based overflow with small passwords
Probably because of sudoers?
rob-olmos··on Nvidia’s hot adapter for the GeForce RTX 4090 with a built-in breaking point
Ah interesting, thanks. Looking more into it, 4x8pin would be 12x12v wires/pins, and the 12VHPWR only has 6x12v for the same max wattage.
rob-olmos··on Nvidia’s hot adapter for the GeForce RTX 4090 with a built-in breaking point
Was there a good reason why they switched from 3x8pin to 1x12pin for so much wattage?
rob-olmos··on Cloudflare CDN Partial Outage
Outside of HTTPS, typically it would be tying the session cookie to the IP address or netblock but because it's Cloudflare IPs, for regular browser navigation requests I don't think there's anything that can be done?
rob-olmos··on Feds seized $311M in Bitcoin, then hacker stole it back
And as the media keeps repeating bitcoin is heavily used for illicit & illegal activity so not only bitcoin itself (that none of the jury holds because those that hold it have been excluded, let alone any of them actually understand it) and then probably exchanging with very specific wallets in this case.. probably guilty despite what the defendant has to say for their actions..
rob-olmos··on React I love you, but you're bringing me down
IIRC in the Gatsby framework it has a built-in GraphQL parser for server-side developers to query data from Gatsby plugins, which can be things like data stores, other APIs, or even a mixture and blended together.
rob-olmos··on Handwritten thank you notes increase sales
Maybe a static site generator that throws in random noise/errors so it feels like a handwritten HTML/CSS site?
rob-olmos··on Library of Database Schemas
Thanks for the suggestion. Also available online via O'Reilly Library: https://learning.oreilly.com/library/view/data-model-pattern...
rob-olmos··on PHP 8.2.0 RC1 available for testing
> first time I heard about it was a PHP fork that implemented fibers, don't recall the name

Probably thinking of HHVM/Hack: https://docs.hhvm.com/hack/asynchronous-operations/introduct...

rob-olmos··on Crawler Hints supports Microsoft’s IndexNow in helping users find new content
IndexNow claims to distribute the pings to other participating search engines[1], and to participate they need to have "noticeable presence in at least one market", so yea still seems to be somewhat exclusive?

Eg, would Ahrefs or Semrush qualify to join the party?

rob-olmos··on Crawler Hints supports Microsoft’s IndexNow in helping users find new content
Yes, but of course only for the search engines that support it. Eg, Google is absent from the list, although they've already had a push/ping sitemap feature.
rob-olmos··on Investors bought a quarter of US homes sold last year
Homeowners insurance covers a lot of that stuff
rob-olmos··on Top Tier Gasoline Worth the Extra Price, Study Shows
I don't think Fred Meyer is Top Tier licensed/certified?
rob-olmos··on Thunderbird Time Machine: Windows XP and Thunderbird 1.0
Still beats Gmail's UI/UX 20 years later
rob-olmos··on Critical Gitlab vulnerability let attackers take over accounts
FYI that Gitlab rotates their package signing GPG key every two years and default yum-cron won't auto-update their packages until the new key is manually approved.
rob-olmos··on A practical guide to securing Google Workspace for a startup
FYI to setup an alert like "Out of domain email forwarding" -- you have to go to Reporting > Login. If you go to Rules and click "create rule" it'll take you to Reporting > Admin, which won't have the Login event types.
rob-olmos··on Playwright: Automate Chromium, WebKit and Firefox
+1 and GCP, and many other hosting ASNs
rob-olmos··on Amazon Linux 2022
Besides going the path of least resistance in AWS, possibly to get OS & package support from AWS if there's already an enterprise-level support plan in place, rather than needing to buy other support subscriptions (eg, RHEL)?

AM2 is able to run in other places so there doesn't seem to be much vendor lock-in compared to a service like DynamoDB, though.

rob-olmos··on New HTTP standards for caching on the modern web
for (c), HTTP 307 doesn't work?
rob-olmos··on QuickBooks Desktop moves to subscription model
One that I came across was on a recurring sales receipt because that's the only way to auto-pay with a card, and when the card wouldn't process the receipt status would still say "paid". Had to click into the receipt to see the card payment failed.

After a few years it was fixed, so that it says "paid (failed)".

Nomad is an orchestrator but with less batteries included:
