jalk··on PWM flicker: Invisible light that's harming our health?
searched for images of "LED bulb teardown", the SMT components are not that tiny, so quite possible to solder with a regular iron. Am I missing something?
jalk··on The Darwin Gödel Machine: AI that improves itself by rewriting its own code
Can't find the reference now, but remember reading an article on evolving FPGA designs. The found optimum however only worked on the specific FPGA it was evolved on, since the algo had started to use some out-of-spec "features" of the specific chip. Obviously that can be fixed with proper constraints, but seems like a trap that could be stepped into again - i.e. the LLM is now really fast but only on GPUs that come from the same batch of wafers.
jalk··on By default, Signal doesn't recall
Whats wrong with https://signal.org/download/linux/ ?

edit: Oh you mean the registration that requires a phone

jalk··on Lego built full-size F1 cars for the Miami GP drivers' parade
tl;dr; 10 cars built, 1 for each team, 500kg steel frame, 400,000 bricks(~1000kg), electric power train, hydraulic brakes, speed limited to 12 mph. Link to video: https://x.com/F1/status/1919092654408638701

There is a single close up image, towards the bottom of the article

jalk··on The US has approved CRISPR pigs for food
Swineflu is one of the arguments for keeping pigs locked away indoors in SPF farms
jalk··on The Gruen Transfer is consuming the internet
You are right, but few people get it when I say "The Swedish Lombard Street"
jalk··on The Gruen Transfer is consuming the internet
Have always been referring to this as “the IKEA maze”.

Went through Copenhagen airport recently. Right after security, there is a sign “All gates ->” which takes you on a detour through the main “taxfree” shop - that is close to. as low at it gets imo.

jalk··on Doge staffer's YouTube nickname accidentally revealed his teen hacking activity
And if the current laws prevent you from getting a security clearance, then that is what it is. Sure the laws can be changed, but in this context it’s probably better to exclude some “reformed” people than letting “criminals” through.
jalk··on ToS;DR
And to protect the service provider from lawsuits.
jalk··on Yes, in the 1980s we downloaded games from the radio
Some computer magazines included a 7 inch "flexi" record with software on. i.e. https://en.wikipedia.org/wiki/Flexi_disc#/media/File:FloppyR...
jalk··on Rest Easy
Can anybody suggest a simple cli tool (besides curl ofc) for calling REST endpoints, since this article didn't provide that ;)
jalk··on ESP32 WiFi Superstitions
Same as Cargo Cult programming: https://en.wikipedia.org/wiki/Cargo_cult_programming
jalk··on In S3 simplicity is table stakes
PDF is not a product. I get what you are day but I can’t say that I’ve ever liked Adobe Acrobat
jalk··on Repairable Flatpack Toaster
I recently replaced the timer dial in a Dualit. Super easy since wires have crimped connectors. The replacement part could have been cheaper (~15% of new toaster)
jalk··on Executive wealth as a factor in return-to-office
Can you elaborate on the tax/rent incentives, as it's not obvious what those are.
jalk··on May 5, Microsoft's Skype will shut down for good
My banks mobile app has a Call Helpdesk button, which simply dials the support number with ',,,<long random number>' appended. That gets you into the fast-track queue and they don't need to ask any security questions as they know it's you. They don't look at the dialing number at all.
jalk··on Despite sticker prices, the real cost of getting a degree has been going down
I guess you skimmed the article, as inflation is not the main argument, but rather that most people don't pay the "sticker" price, but get various "discounts"
jalk··on DOGE's only public ledger is riddled with mistakes
I would not be surprised if that "no option" list involves videos of Trump from FSB bugged hotel rooms.
jalk··on Hard disk fraud: long runtimes on new Seagate hard disks
Yet the Chinese Garbage is not CE marked, but CE marked :( https://www.hqts.com/differences-between-ce-conformite-europ...
jalk··on What Have We Forgotten?
I believe that google login cookies, are persistent cookies with a longish max-age/expires value, so that is not surprising, and hence why you have to use google periodically to "refresh" the cookies.

Here is what MDN[1] says about session cookies:

> Session cookies — cookies without a Max-Age or Expires attribute – are deleted when the current session ends. The browser defines when the "current session" ends, and some browsers use session restoring when restarting. This can cause session cookies to last indefinitely.

I was unaware of the "session restoring" point. This has to be considered if wanting to "unforget" the use of session cookies.

(edit for layout)

jalk··on What Have We Forgotten?
The browser session concept has “eroded” over time. Many, if not most, laptop users rarely closer all browser windows and hence sessions can last months. Haven’t checked but I wouldn’t be surprised if session cookies survive a browser update, started from the menu at
jalk··on Human corpses keep moving for over a year after death, scientist says (2019)
If it was a steak through the heart, then maybe.
jalk··on DeepSeek releases Janus Pro, a text-to-image generator [pdf]
If it issues tickets on site, we will at least have easy access to toilet paper. Saw a documentary about that once ;)
jalk··on The Taylorator – All Your Frequencies Are Belong to Us
Otherwise known as frequency swifting
jalk··on The case for letting Malibu burn (1995)
The insurance companies did say "enough is enough", which is why the FAIR plans exist - i.e. https://www.cfpnet.com/
jalk··on CCL: Categorical Configuration Language
> You want to introduce data validation and type-checking in your config? Fine, you can just ask users to provide type annotations in the format you want...

No - the users cannot choose type - they cannot suddenly decide that they want to provide a date where your parser expects an URL, or you are suddenly just making users repeat the schema

> Every software MUST WORK WITHOUT A CONFIG!! > So, empty config or no config file at all must be a valid configuration

Loads of scenarios where I want fail-fast over a running but broken system: "WARN AlertSystem URL not configured: alerting disabled" "WARN No credentials store configured, adding admin/111111" ....

jalk··on Making Beautiful API Keys
I'm 99.9999% sure that your 1% risk is incorrect, given they are just reformatting UUIDv7
jalk··on Who would buy a Raspberry Pi for $120?
and keyboard!
jalk··on US could ban TP-Link routers over hacking fears: report
> fundamentally we need to move to a home networking model that involves isolating all clients completely (especially cameras and smart TVs) That is currently solved by using separate SSID's on individual VLANs (i.e. main, guest, iot) and firewall rules "mediate" the connection between the VLANs. I'm handrolling this with OpenWRT on APs and main router (NanoPI R5C) with ISP cable router is in bridge mode. Can't say it was easy to set up though
jalk··on 2400 phone providers may be shut down by the FCC for failing to stop robocalls
Can you elaborate on how using a VoIP client, makes it clear who is calling?
