Attorney General Bonta: Unredacted Federal Lawsuit Against Meta “Damning”
OAKLAND — California Attorney General Rob Bonta today announced the public release of a largely unredacted copy of the federal complaint filed by a bipartisan coalition of 33 attorneys general against Meta Platforms, Inc. and affiliates (Meta) on October 24, 2023. Co-led by Attorney General Bonta, the coalition is alleging that Meta designed and deployed harmful features on

Ed Zitron is really on fire preaching against the general malaise we're all feeling from the Rot Economy and the enshittification of everything, like this recent post:
Never Forgive Them
In the last year, I’ve spent about 200,000 words on a kind of personal journey where I’ve tried again and again to work out why everything digital feels so broken, and why it seems to keep getting worse, despite what tech’s “brightest” minds might promise. More

I decided not to open a #Bluesky account because I have my hands full here following a chronological feed on a variety of topics. I was able to transfer enough friends I knew from the old Twitter when I made this account to get going, and now I just follow anyone who posts anything I find interesting or insightful, to keep building a network.
#Mastodon is at heart a hobbyist platform, and that's okay. There's no imperative for growth at all costs, or even forcing consistency between instances.

I can only put 500 chars in a toot on this server, but I see others posting really long toots, the bulk of which is hidden for me behind a "Read more" link, thankfully.
I'm old enough to remember the BBS days, and this is not a whole lot different than FidoNet, UUCP, BITNET, or other federated forums of years past. Of course those systems had to be store-and-forward because instant high-speed Internet from anywhere at all times was science fiction and reality was often a 2400 baud modem.
-
To put that in perspective, "baud" is bits/second, but on an RS-232 serial link you have a start and a stop bit for each byte so you have to divide by 10 to get bytes/sec, not 8.
I'm just old enough to remember Commodore selling a 300 baud and a 1200 baud modem, and I was fortunate enough to have the $70 to buy the faster one. I still have it, although I'm not sure what it's good for. I have a lot of retro stuff I need to sell. I had a friend with the 300 baud one, so I know it was painful.

@jhamby Um, actually…
Baud is voltage changes per second (technically “symbols” per second, but a symbol is voltage level)
Each symbol can encode multiple bits.
Up to 2400 bps they used simple 2 state logic. Thus a 2400 bps modem ran at 2400 baud.
I was going to say that 2400 baud was the theoretical limit to single twisted pair copper wire + POTS bandwidth limitations, or at least it *was* the limit in 70s and 80s. Trying to drive a signal faster than that results in signal echos I believe. (I don’t think I ever knew the physics.) Either way, the signal gets corrupted.
But how did modems get faster? Encodings. A 9600 “baud” modem actually ran at 2400 baud, but used some encoding tricks to send 4 bits per symbol (4 * 24 = 96), and so was more correctly a 9600 bps modem.
Something must have changed by the mid 90s, because I just read that 56 kbps modems ran at 8000 baud.
Anyway, undergrad networking class ftw!
-
@jhamby ahh, so in your thread you mention that 56k modems required a digital end on one side of the transmission (I’m thinking the phone switch) and so that’s the technology change that allowed bauds in excess of 2400.
-
@jonathankoren You can get up to 33.6 kbps with analog phone lines at both ends.
I believe the downlink speed (digital to analog direction) was limited to 53 kbps in the USA due to power limits (of the analog signal, I guess).

@[email protected] @[email protected] I mean hell nowadays if you don’t mind some digital modulation you can get megabit speeds over twisted pairs (VDSL2 https://en.wikipedia.org/wiki/VDSL) which is how I’m typing this. I have two bonded phone lines providing me about 100mbps of download when it’s all said and done. of course you know back with 56k modems you didn’t exactly have access to the same sort of digital logic we have now (and especially not the sort of compactness either)
-
@[email protected] @[email protected] it’s interesting to note that bell labs was responsible for doing some digital modulation (I think they reached gigabit speeds?) I don’t remember though.

@[email protected] @[email protected] digital signal processing and analog signal processing are like comparing our modern tools made from tool steel and materials like tungsten carbide to the Stone Age

@puppygirlhornypost2 @jhamby the 2400 baud limit idea comes from my memory of a lecture almost 30 years ago.

@puppygirlhornypost2 @jonathankoren
I had AT&T U-Verse fiber-to-the-curb in 2009 that was quite impressive, but that's only traveling a short distance. I didn't realize phone company DSL could go that fast.
I'm sure most people are unaware that a selling point of 10BaseT was that you could run it over two pairs of UTP that your office building installed to use for phone lines. I assume that trick doesn't work for gigabit.
Gigabit needs 4 pairs (vs. 2). I wonder if it works over phone wiring.

@[email protected] @[email protected] mine comes from an offhand comment regarding bell labs so I am not sure its accuracy. Gigabit sounds like a stretch but considering we can do terabits in the lab it’s entirely possible. Could have required some very specific equipment or something else making it infeasible. I mean my home internet gets megabits out of phone lines buried in the 1970s (or earlier - hard to date those but we have signs from the original bell and AT&T just plasters over with labels the current subdivision and who to contact)
-
@[email protected] @[email protected] which still I mean all things considered 100mbit is still a very respectful speed and it’s even more impressive that this is just 2 analog phone lines

In my day job, I'm working on an avionics app server + Ethernet switch + cell modem + Wi-Fi. I've learned more about Ethernet than I ever wanted to know, as well as about avionics protocols like ARINC 429 and ARINC 717.
Thankfully this application doesn't need AFDX, which is the special customized version of Ethernet with guaranteed delivery and redundancy.
I believe the AFDX switches in Boeing 787's need rebooting every 51 days.

@puppygirlhornypost2 @jonathankoren
"The US [FAA] has ordered Boeing 787 operators to switch their aircraft off and on every 51 days to prevent what it called "several potentially catastrophic failure scenarios" – including the crashing of onboard network switches.
The airworthiness directive, due to be enforced from later this month, orders airlines to power-cycle their B787s before the aircraft reaches the specified days of continuous power-on operation.
Boeing 787s must be turned off and on every 51 days to prevent 'misleading data' being shown to pilots
US air safety bods call it 'potentially catastrophic' if reboot directive not implemented

This is what happens when you try to use new-fangled proprietary technology instead of good old-fashioned 1970's protocols.
The new product I'm working on is really cool, and I'll be excited to see it in use when we ship it to airlines. The feature set is called AID: Aircraft Interface Device, and it talks to EFB (electronic flight bag) apps running on either an iPad or a more expensive and laggier permanently-installed tablet.
