rathel··on Danish military intelligence uses XKEYSCORE to tap cables in co-op with the NSA
They always sound so memorable yet mysterious, especially so the ones created by concatenation of two ordinary words, like ETERNALBLUE or FOGBANK.

We should make a GPT-based generator of USA secret codenames ;)

rathel··on AMD to Acquire Xilinx
Apparently after Altera acquisition they sought "synergies" in all the different divisions. My friend was an intern who was tasked with porting some of the network protocol stack to SystemVerilog. Apparently it did work and SystemVerilog was the right HDL to use because of support for structs that can map to packet headers. I'm not sure it's being used in production.

It'd be interesting to see how AMD will execute and integrate this acquisition, considering they are less of a madhouse company than Intel.

rathel··on BL602/BL604 RISC-V WiFi and Bluetooth 5.0 SoC will sell at ESP8266 price point
Yeah, it's interesting considering that supposedly engineers are not significantly cheaper in Chinese tech hubs compared to the West.

The Western chipmakers are being disrupted with chips that are good enough, not realizing that cheap price creates a new quality, enabling devices not possible before.

Sure, the firmware and SDK had some of bugs and missing features to iron out, but they came a long way since the release and now are solid enough to put devices like Sonoff inside your electrical boxes and walls.

rathel··on A Programmer’s Intuition for Matrix Multiplication
True, but I don't agree with what he said here @ 8:00

https://youtu.be/ZxYOEwM6Wbk?t=481

Is this really the case? I checked Wikipedia and MathWorld and nobody makes a distinction between e^x and exp(x).

Even if it's a "white lie" for didactic reasons, I don't buy it, it will be much more confusing down the line for students.

Math is about finding structures governed by some rules and then generalizing them. To me the e^x defined as repeated multiplication conceptually is the same thing as the exponential function, just over broader domain. Why? You can interpolate between integer-valued X's using geometric mean. e^3 = sqrt(e^2 * e^4). What stops you from interpolating this recursively to achieve in the limit the exponential function over real numbers?

rathel··on I reverse engineered McDonalds’ internal API
This map uses OpenStreetMap-based map tiles (this style is called OSM Bright) served from MapTiler.

But the attribution (see https://osm.org/copyright and https://www.maptiler.com/cloud/terms/ ) is not there.

Could someone ping the author on Twitter, as I don't have an account? Thanks.

rathel··on New version of Mapbox GL Native SDK core will be closed source
There's somewhat of a resentment at Mapbox from the OSM community that they hide the required attribution [1] behind an "i" icon on mobile. This information besides satisfying the licence requirements serves as a "powered by" acquisition channel for OSM, like discussed earlier this week on HN [2].

That said, Mapbox does offer some QA tools for OSM mappers to use, so the net result is hard to judge.

rathel··on New version of Mapbox GL Native SDK core will be closed source
Probably being butthurt about OpenMapTiles and MapTiler "stealing" their business? But then again, Mapbox, judging by the buzzword-laden landing pages and focus on "contact the sales team", seems to be catering to the corporate big fishes. (I may be mistaken though).

Another thing is that Mapbox is owned by SoftBank which hasn't had a good year so far and has to recoup WeWTF losses somehow.

And thank you for the link - I wasn't able to unroll the thread in Threader. I'm probably out of the loop if Twitter has broken their API.

rathel··on Car Paint Colors Have Gotten More Boring over the Years
You say "greige-ification" while Polish architecture and design communities lament the pasteloza ("pastelosis") trend. It came to be when existing commie blocks were thermally insulated with styrofoam and their façades painted with pastel colors in 2000's and 2010's. You can't please everyone, I guess... Although some of the designs created in response to "pasteloza" use bright colors sparingly, so there's that.
rathel··on Tell HN: FB tracked my sensitive buy outside FB, cant delete a suggestion in app
For FB, I use an e-mail that is no longer my primary one for almost a decade - all other activity is on a different one.
rathel··on Tell HN: FB tracked my sensitive buy outside FB, cant delete a suggestion in app
I _suspect_ I might have clicked a link for order tracking outside private mode (Gmail's Chrome WebView, go figure...)

Now, to prevent such events in the future I installed Firefox on my smartphone along with uBlock Origin. I use FF on desktop since forever, should have used it on mobile as well.

rathel··on Tell HN: FB tracked my sensitive buy outside FB, cant delete a suggestion in app
Deleted app data completely. Made no difference. (I'm on Android).
rathel··on Suicide Linux (2009)
Oh no, someone jokingly acknowledged that cultural differences exist. How horrible of them.
rathel··on Amazon hid its safety crisis
Speaking of Amazon trying to downplay its wrongs, I recall there was a post here that counted Amazon PR team at 400-odd people. But I could not find it. Are they so effective or have I Mandela'd myself and this did not happen?
rathel··on The Forgotten Ones: HP Nanoprocessor
It seems kind of an inelegant solution to me. They could just solder a resistor to the package at the factory or do some variation of that idea.

Now, modern processors are binned, too, depending on the CMOS process corner they turned at. Slow ones have advantages too - leakage is much smaller, so better suited for mobile.

Or, in case of some SoC, if it's FF (fast NMOS, fast PMOS), they can reduce core supply by tens of mV.

There's even a company specialized in PVT (process, voltage, temperature) monitoring for newest SoC's - Moortec.

rathel··on Ask HN: A kind request please about the use of acronyms?
I second that! Considering how crap Google results are these days, even usual methods to decode acronyms often turn futile
rathel··on Autodesk criticised by architects
If we're talking about IC EDA - then the OpenAccess library format (anything but, more like InteroperableAccess at best) is binary.

The industry standard version control here is Perforce. Perforce being Perforce, there even are 3rd party solution to de-duplicate users' workspaces in order to save gigabytes of disk space.

rathel··on The internet is multilingual but you need to learn Mandarin
Weren't it for the really un-pragmatic script, I'd considering it learning it as well, even if just for the "it's frustrating there's something outside of our reach". Because, well, it is.
rathel··on Editorial board of Index and more than 70 staff members resign
It's a consolation that Kaczyński was not able to gather supermajority in the parliament to change the constitution. It's unlikely to happen anyway, as he divided the Polish society in half. His party will probably rule for some time, but not gain much more support than today. He antagonized simply too many worker groups and professions out there. Another thing pointed out is that Hungary has somewhat more unequal development than Poland - and in both countries the ruling parties catered to the poor regions. Last but not least, for better or worse, there's dissent against authority in Polish blood.

Tl;DR it will suck, but Poland won't have second Hungary.

rathel··on The AirPods Pro “Rattlegate”
To reify something you have to name it, apparently.

I see nothing wrong about it. Apple spends billions on R&D yet still manages to push crap designs to the market (as evidenced by Louis Rossmann).

If naming something *-gate will make a dent in the public's "premium" image of Apple, I'm all for it. They sell the same crap as others, just overpriced, maybe with software that's better in some aspects.

Apple almost never owns up to their mistakes when it comes to defective product design.

rathel··on Chipmaker Analog Devices to acquire Maxim Integrated for $21B
A bit of a premium? I'd say their prices are an insult to their customers. It's not even new chips where you'd expect this as they need to recoup NRE. Oh no, they price gouge on designs that are decades old.

Avoid them at all cost.

rathel··on Invite Rick to Rick Roll Your Zoom Calls
Polish politicians had this in 2013:

https://www.youtube.com/watch?v=vljNIU38sUU

(For context: Macierewicz is a nutjob politician at PiS, then opposition, now ruling party. He led an unscientific "investigation comitee" to explain how Smolensk 2010 plane crash happened. It obviously never really explained everything, for its goal was to accrue political capital on the death of president Lech Kaczyński (PiS), claiming it was Russian interference, TNT, artificial fog, birch and whatnot.)

rathel··on Openstreetmap, a global map for worldwide insight
Because of the OSM data model, changes can't be really held in "unaccepted" state. One would run into editing conflicts[1].

On Wikipedia withholding edits until review works in some language versions [2], but because Wikipedia pages are "atoms" that stand on their own, they have it easier.

rathel··on Openstreetmap, a global map for worldwide insight
There is no validation team, however everyone can check the latest edits [1]. If there's a developed community in a location, say someone in your city, you can validate it yourself. Someone can use Notes feature [2] and report that the street has inaccurate information - by linking to some photo proof.

Thankfully many (not all, like POI) edits can be checked via satellite imagery [3], of which OSM has permission to use many - global ones being Bing, Maxar, Esri, Mapbox. With so much sources of imagery, the update rate is acceptable for most places.

All in all, the result is not as bad as you'd expect. From normal people I hear that OSM is "very accurate" (at least here in Europe). Oddly enough, nobody says anything about blatantly fake info, which indeed does very rarely slip, but apparently gets reverted.

Now as I am thinking, there is "validation team" of sorts, that's Mapbox data team, which uses OSMCha [4] to flag suspicious changesets and checks them (albeit not by physically going there).

rathel··on Openstreetmap, a global map for worldwide insight
Examples, please. There is bad info here and there, but it's minority (if you want 100% accuracy it's delusional, even Google Maps has a ton of crap, starting from skylights that AI recognized as buildings [3] to businesses you can't even tell they exist).

Also, for a long time now each changeset can be discussed. [1]

I have a hunch you may be from a country where the community has not took up too much [2]. These tend to have more dubious data.

rathel··on Die shrink: How Intel scaled down the 8086 processor
The shrink is usually done at the fab. I.e. layout designers pretend to draw in a higher nm node, then the fab scales the layout. Like 28->22 nm, or 16->12 nm and so on.

Transistor models stay roughly the same, often they include SPICE command .option geoshrink=x where x is a desired shrink factor.

There may be additional DRC rules for the layout in the lower node that necessitate corrections.

rathel··on Jim Keller Resigns from Intel, Effective Immediately
Might be true, recently there have been highly boasted improvements in the RTL-to-GDSII pipeline, using AI, as one does. Both from Cadence and Synopsys.
