RachelF··on Jelly Star – The Smallest Android 13 Smartphone
iPhone 4 or 12 mini size is probably ideal for me personally.

While this is small, it is double the thickness of most modern phones.

Still, it is great to see a bit of creativity in the smartphone market. Most phones are pretty much the same these days.

RachelF··on Anna's Archive Faces Millions in Damages and a Permanent Injunction
Yes, too much for one person, but collectively it is possible to keep it alive.

If anyone wishes to help, you can generate a chunk in 1TB units and seed via BitTorrent here:

RachelF··on Reverse Engineering the Verification QR Code on My Diploma
There are a few applications that do that - but it is a patent minefield, courtesy of the biggest patent troll in history:

RachelF··on NexDock turns your smartphone into a laptop
Yes, Samsung has had their "Dex" which looks just like NexDock.

Modern Motorola phones have a similar feature.

VNC has been around for a long time.

It just seems like something people don't want to use. I'm not sure why, though?

RachelF··on An unexpected journey into Microsoft Defender's signature World
Nice big attack surface there. I wonder what's to stop someone modifying the vdx virus definition files to include something like Edge.exe or Explorer.exe?
RachelF··on Company offers unofficial security patches for Windows 10 until 2030
Ironic, because MS are now saying that anything on the Internet can be used to train AI, and their ISO's are available. Perhaps using AI in the process of making these patches will make it OK ;-)
RachelF··on Ask HN: what are examples of successful "open-source alternatives"?
Don't forget BSD - all Apple operating systems are based on it.
RachelF··on Writing GUI apps for Windows is painful
No one wants to talk about it or Delphi anymore.

Programmers are just as fashion-concious as the Milan catwalk designers.

RachelF··on 6 months ago, I left the bullshit industrial complex
Sadly, advertising is the best way to pay for your online product in most cases.

Micro-payments have been tried a few times but most people did'nt like to pay for stuff that they used to get for "free". Since everyone is now locked into a few big tech platforms, they can now supplement their ad income by charging users, too.

RachelF··on LINQPad – The .NET Programmer's Playground
Thank you for that!
RachelF··on LINQPad – The .NET Programmer's Playground
I agree that MS is not completely serious about C#. They spend too much time on adding new language features but not enough on the essentials: There are big holes and missing bits in the Windows API wrapper that have been there for two decades. Most new MS apps like Teams of VS Code are not written in C#. I suspect it will limp along with hot and cold support from MS.
RachelF··on Japanese words and names sound African (2022)
Something amusing about Japanese vs Xhosa (a Bantu language) is that their words for yes and no are reversed:

Japanese Hai = yes, Xhosa - Hai is a no

Japanese eeye = no, Xhosa - ewe is yes

RachelF··on Faxes From the Far Side (2015)
> what the tolerance on something like this is?

They are pretty wide. You can find the answer by looking at some online antenna calculators. Bear in mind that it also depends on the orientation of the rod relative to the incoming wave, and to the polarization of the wave.

Modern stealth aircraft tend to reflect the signal away from the transmitting radar or absorb it. The windows tend to have thin conductive gold layers on them to stop radio waves getting into the cockpit and finding a resonator. Similarly joints on the fuselage are sealed.

However, the design of stealth is limited to a frequency band, normally X-Band (8 to 12GHz, a few inches in wavelength). At a lower frequency, like 1GHz they are not stealthy, which was one reason why an F-117 Stealth fighter was shot down in the late 1990's.

RachelF··on Australian Border Force searched phones of 10k travellers in past two years
There's another symptom of this. Those in power are exempt.

When an MP, called Julie Bishop, had her bags searched, she used her power to get those involved sacked.

RachelF··on How many photons are received per bit transmitted from Voyager 1?
What is equally impressive is the number of photons received from radar imaging of asteroids.

They are closer, but the radar equation received power is inversely proportional to range to the fourth power, not range squared as with Voyager.

Anything proportional to 1/R^4 degrades very quickly.

RachelF··on How many photons are received per bit transmitted from Voyager 1?
Two main reasons for recognizing the photons: They have a specific frequency, 8.3GHz in this example. It's like tuning an FM radio to a station. The photons are coming from a specific direction.

As to how they are decoded, you'll need to understand some modulation techniques.

RachelF··on An intuitive guide to Maxwell's equations (2020)
A great article. Good to see they give Heavyside the credit he deserves for what everyone now calls "Maxwell's equations".
RachelF··on Mobifree – An open-source mobile ecosystem
Large parts of Android (Google Play Services) are not open source.
RachelF··on Mobifree – An open-source mobile ecosystem
The main problem now with many custom ROMs is VoLTE support. Many countries are shutting down 3G networks, and many VoLTE solutions (for 4G and 5G voice) are not available in the open source ROMs.
RachelF··on Fractal Geometry
I don't know - the machine I played with it on was a 16MHz 386, and the IFS software was not optimized. But it was way slower than DCT-based JPEGs to compress.

The odd thing about it though, was that it could upscale smoothly. A 320x200 source could be decompressed at 640x400, and it would sort of intelligently "fill in the gaps" on textures etc.

RachelF··on Fractal Geometry
For a while in the 1990's IFS (fractal) image compression was a serious competitor to JPEG.

Microsoft Encarta used it on the encyclopedia CD-ROM.

I don't know what happened to it. It was pretty slow to compress.

RachelF··on An adjustable filter that can prevent interference in the range 600 MHz to 6 GHz
Yes, this article is marketing. They've just made a prototype smaller filter.

YIG filters have been around for decades. They are electrically tunable. However, they are slow to change frequency and can have an odd phase response.

RachelF··on Ask HN: What makes Windows 11 perform much worse than Windows XP?
I'd add to 4, having seen a bit of the Kernel code. There's a lot of duplication of code, when new developers or teams come on board, they often just re-invent the wheel, rather than using existing Kernel funtions.

I would guess that most of the 15 NT developers from 30 years ago have long since left.

RachelF··on Ask HN: What makes Windows 11 perform much worse than Windows XP?
Yes, take MS Teams for example. Takes around 1000MB or RAM. Older chat apps used way less. IRC used less than 1MB, sure it didn't do voice or video, but it could do things Teams still cannot do.
RachelF··on Ask HN: What makes Windows 11 perform much worse than Windows XP?
Windows 11 won't run most DOS or Windows 3.1 or Win16 Windows 95/98/ME programs.

XP does.

RachelF··on We're ending our Samsung collaboration
There's a economic reason mobile phone manufacturers don't want you to repair the phone - they prefer you to buy a new one.
RachelF··on S3 is showing its age
Thanks for that.
RachelF··on S3 is showing its age
Yes, it can't write to parts of a file.

It also can't read (seek) into the file (or couldn't when I last looked at it).

It is not a file system, but is often mistaken for one.

RachelF··on ICC prosecutor seeks arrest warrants against Sinwar and Netanyahu for war crimes
ICC signatory countries are meant to arrest anyone on the ICC warrant.

South Africa did not with a Sudanese war criminal: "As a signatory to the Rome Statute that governs the jurisdiction and functioning of the Court, South Africa was obliged to arrest al-Bashir when he was in the country, and to extradite him to The Hague to face trial."[1]

Last year, Putin cancelled a visit to South Africa as there's an ICC arrest warrant out for him.

RachelF··on Introducing Copilot+ PCs
Yep, I have to do it occasionally.

The same with Visual Studio. It is referred to by a year, eg Visual Studio 2019, but then you need to look in the make files for the actual version number of the project, and then look on Wikipedia for a table matching versions to years.

Wikipedia at least has decent docs on versions.
