Change to SMS API at @aaisp :-

Later this week.

Basically we are no longer handling or reporting the invalid UTF-8 byte sequence 0xC0 0x80 for a NULL (used for 8 bit coding SMS).

We are now treating U+2400 (i.e. ␀) as a NULL, i.e. 0x00 in 8 bit coding, so a UTF-8 sequence using only U+0001 to U+00FF and U+2400 is treated as 8 bit coding for values 0x01 to 0xFF and 0x00.

UCS16 also now treats 0x0000 as U+2400 each way, but we don't know of 0x0000 USC16 use cases that this would impact.

@revk @aaisp 0x00 as in @? or like binary SMS?

afink,
@afink@mastodon.sl avatar

@revk @aaisp so its "@" according to gsm character set

afink,
@afink@mastodon.sl avatar

@revk @aaisp gsm does use 7bit character set (gsm TS 03.38) or ucs16. There is no utf-8. 8bit encoding is only used for binary sms and if its text (no udh etc) gsm character set is assumed. in smpp you send 8bit data which get packed into 7 buts by the SMSC but its still GSM 03.38 character set, not utf8 or latin1 or so.

hence someone sent a @

@afink@mastodon.sl avatar

@revk @aaisp ok so you have 0x00 on the API side not the GSM side. And yes you can have that in UTF8 if you have escapes and multibyte characters. And besides that: cusomers sometimes send rubbish. be ready for it, no matter what.

afink,
@afink@mastodon.sl avatar

@revk @aaisp 8bit encoding on the GSM side is not meant for text. There is no ASCII or Latin1 on any GSM phone. Its GSM charset or UCS2. GSM charset has been extended to include some national variants by escape sequences (wikipedia has it nicely documented). And of course its all a messy workaround to put something modern on to some old tech wich was never meant for it.

@revk @aaisp I bet with you its not the case

As a web developer in a past life and doing it pre-broadband (56k all the way!) this is gross and unnecessary. Having had to poke around under the hood of a few webapps over the years you can tell no one knows any HTML (or CSS for that matter). Making shit on the web without knowledge of the fundamentals is a broken way of doing things. Enjoy JavaScript Bloat in 2024 @ tonsky.me https://tonsky.me/blog/js-bloat/

I want a cross-platform Photos gallery app that manages photos in real folders.

When you "favorite" a photo I want it to create a symlink to the original photo inside of a "Favorites" folder.

Does this exist?

@taoeffect its called Finder?

Has anyone here used a smart plug to detect when an electrical appliance has finished doing something?

For example, I want to plug in my rice cooker and get an alert on my phone when its electrical use drops to zero.

Ideally using something like - but I'm not fussed.

@Edent @revk your ISP is not supporting IPv6? He only knows since 30 years that IPv6 is becoming mandatory. Maybe you should change to a more modern ISP

afink,
@afink@mastodon.sl avatar

@Edent @rayrob complain to your ISP that you can not reach certain websites which are ipv6 only... . maybe they wake up then

@Edent wow. DOCSIS is waving from the middle ages... what a bummer. send them faxes to complain! they probably still read them

@nblr sure but its still precedented by a #. Why they choose that strange name for routing table nr. 1 however is beyond my knowledge. I modify that file often

Cursed network cable.

Still somehow got 100mbps link

@Ryanteck @revk 4 wires is enough for 100M

afink,
@afink@mastodon.sl avatar

@revk @Ryanteck If your port is 1G capable its mos likely supporting MDX which crosses over for you

afink,
@afink@mastodon.sl avatar

@revk @Ryanteck i dont see any ALT text nor broken wires. some potential cracks in the plastic maybe

afink,
@afink@mastodon.sl avatar

@revk @Ryanteck PS: the wirepairs are wrong as 1-2, 3-4 , 5-6, 7-8 instead of 1-2, 3-6, 4-5, 7-8 but at the end every pin 1-8 is electrically connected to 1-8 at the other side. deprnding on the lenth you get more crosstalk, bad impedance etc. thats also a reason for being less performing on higher speeds which are more selective on HF issues

Stop complaining about 8 gigs of RAM on a $1600 machine. Don’t you realize every M3 Mac comes with this amazing bit of software?

@paul yes except it does need a 68020 emulator to run which didnt fit the disk...

If a car manufacturer like makes a car that's connected to the Internet, with no off switch, do not buy it.

It's that simple.

There are so many great used cars out there that you can buy instead. Give the cabal the 🖕

@taoeffect when you buy a car in europe you have the GDPR allowing you to opt out. They cant reguse it. I forced my car dealer to find the form to opt out. Dealers are motivated to sell. Make them work for you to get these things stopped before it fires back on you one day.

@taoeffect why not write a clone instead which can contine the work hitlist did?

If I want to run a dead simple VPN from a Mac into my house network what should I look at? Router is pfSense, can run any VM needed, don't have a static IP, do have DDNS setup.

@paul I use Wireguard on my Mikrotik routers. great performance. Setup easier than OpenVPN which I never ever got to work.
