j/c but why are we still maxing out at 1gb ethernet connections? why have the speeds essentially not progressed in 20 years? you can get a 40gb connection by just using usb-c on modern machines. what's going on? (curious about why this is the case industry-wide, i think this project is really cool)
Copper Ethernet standards tend to be specified for over 30 metres, and go (preferably) up to 100m. That’s pretty tricky to do, you need quite thick cable with individually foil shielded pairs to achieve those kind of long distances at 10Gbps. 40 Gbps USB-C on the other hand is recommended to travel over a maximum of a metre or so of cable, with the recommended being 0.8m (2.6ft) of cable or less! Thunderbolt cables that go longer need active driver chips inside the cable in each connector to make the whole thing work.
Then there is the power issue, 10Gbps Ethernet uses significantly more than 1Gbps, so a 40GBase-T switch would be even more power hungry.
The combination of these has meant that basically most people just use fibre if they need more bandwidth.
The intended use-case for this board is some robotics applications. I don't think parts of robots need to communicate via gigabit. 10/100 Base-T is presumably easier to implement and thus cheaper and smaller (which is the point of this project)
You can get 40+ Gb/s over USB-C or connections like DisplayPort and HDMI by using thick expensive cables that top out around 10ft of length. Beyond that, price starts shooting up as you get either optical transceivers or active retimers/redrivers built into the cable assembly.
Ethernet over copper is designed for cable runs of over 300ft and has to be much more forgiving of poor quality cables and connectors. That means for the same level of complexity and power consumption in the transceivers, you're just not going to be able to get as much bandwidth.
Ethernet equipment suitable for 2.5Gb/s and 5Gb/s in consumer equipment (cheap, low power) is now readily available, but there's not enough demand to drive pricing down to parity with 1GbE and completely supplant it. 1GbE is good enough for most consumer use cases, especially given the dearth of multi-Gig WAN connections in the consumer market, the lack of popular use cases that would benefit from slightly faster LAN connections, and the continuing improvements to WiFi.
Typically I like to read HN comments for insightful discourse focused on details of the topic at hand by relevant experts. It is a terrible failing of HN that this useless comment is promoted to the top.
It is like if there were a detailed blog post about rusts type system and I was to comment “Why would anyone use rust when they could use X instead?”
- he lent his own hedge fund $8b collateralized by tokens he controlled issuance of (FTT, SRM, MAPS, OXY). At full size, the liquidation price of these tokens was 0 (he also purchased billions worth of FTT off the market when he could print them himself for free?).
- Sensing alameda was insolvent and customer funds were misappropriated, customers withdrew until they ran out of liquidity.
- Withdrawals were suspended
- Citing Bahamian authorities requests to unfreeze assets of bahamian residents, withdrawals were opened back up for bahamian residents. Hundreds of millions were withdrawn. Bahamian authorities have since made statements that no such requests were made (so this was just insiders stealing even more).
- Approx $500m of assets were drained from FTX wallets at the same time as FTX databse records were cleared (obviously not a hack, just insiders stealing even more).
- SBF goes on twitter to make new one-letter tweets while simultaneously deleting incriminating tweets so as to not trigger deletion bots picking up that he deleted said tweets.
Ongoing theft and destruction of evidence out in the open after stealing 10 billion dollars from over 1 million depositors. SBF has still not been arrested. This all but confirms the wildest of conspiracy theories.
> - SBF goes on twitter to make new one-letter tweets while simultaneously deleting incriminating tweets so as to not trigger deletion bots picking up that he deleted said tweets.
This part seems to have been mostly speculation. He deleted 118 tweets & retweets, so his one letter tweets did little to cover his tracks[1]. I have no idea why he did the one-letter thing. Maybe to get attention?
I dont think he didnt delete any tweets. The counts were off because people like Tom Brady and other famous people associated him where deleting re-tweets.
You kind of went off the rails there in the final sentence. Are you saying that any of this adds credence to the silly idea that Democrats are beholden to SBF campaign money?
It’s a silly idea that being the second largest donor to a political party in the US buys you special favors? Why else would anyone give that kind of money to politicians without expecting something in return?
I'd expect that the something in return buys you a king's seat at the regulatory table, not quite a get-out-of-jail-scott-free-for-stealing-billions card.
I'm sure that in a few years, once the courts get everything sorted out, we'll learn which of our prejudices is closer to reality. As of today, though, we're both just speculating.
Bingo, and the line from electoral politics -> regulation is straight, legal, and requires one step. While filtering political donations through judicial + investigative bodies with egads of separate oversight & career employees & little to no electoral influence would be impossible to manage. Not for 28 million, you would have to buy a loooooot of people off and get extremely lucky. That’s why it doesn’t happen. The get out of jail free card, that is.
Donations buy you access, not specific outcomes. Just the ability to get a hearing for whatever kinda-reasonable-ish parts of the stuff you want there might be is really, really valuable.
And yes, both are corrupt, but one is business as usual and the other is a serious federal crime that prudent members of congress avoid.
"This tax credit gets extended" is an outcome. "30 minutes with the Member and their chief of staff to discuss the vital importance of this tax credit to industry X" is not an outcome. You can problematize and subvert any scheme of categorization if you like, so go wild if it makes you happy, but honestly who has the time?
Sorry but the "wildest conspiracy theory" is that Democrats sent money to Ukraine, Ukraine deposited the money at FTX, and SBF donated the money to Democratic congressional campaigns. Nothing about what we know today lends any credence to that theory.
That some guy with access to a lot of cash tried to buy influence is not a "conspiracy theory" because it is unilateral. And, if that's what he was trying to do, it seems like a really poor strategy since you cannot really buy influence over law enforcement that way.
> Nothing about what we know today lends any credence to that theory.
I'm personally much more interested in the billions or the tens of billions that disappeared (in the bank account of tether/Deltec?) than in the petty amount that went to the democrats but... It's a fact that media were posting articles explaining how crypto was helping Ukraine (and there was a government ran website in Ukraine accepting crypto donation).
SBF's very mom was running a political fundraising thinggy.
It's also a fact that at least one US congressman is saying Gary Gensler was allegedly working hand in hand with FTX to allow SBF/FTX regulatory capture of crypto exchanges.
I'm not saying they did: I'm saying a US congressman says he has records indicating that.
These are facts. Now did these donations to Ukraine found their way back to FTX? (and if that's the case there's at least some truth to the conspiracy for it's a fact that SBF was donating stolen money to her mommy's fundraise)
I think it's a bit early to dismiss with the back of the hand the information people are digging out.
The one thing that seems certain is that if we were to depend on the journalists from the New York Times to investigate on that we wouldn't go very far.
The usual angle is also going to be used for sure: "The wildest conspiracy theories are false, hence nobody besides SBF did anything wrong".
People are trying to connect the dots. And with 130 companies, blinded journalists, a political party receiving $40m in donation, etc. there are certainly dots that do need connecting.
Congress hearings in december for a start. Should be interesting (even if I don't have high hopes).
I could see Ukraine donations that hadn't been withdrawn getting caught up in all of this, but I'm highly doubtful there was some weird shell game going on. Not because it wasn't possible, but because it wasn't necessary. SBF was openly throwing cash around to buy political and media influence. There wasn't any need to skim government cash when he could use ~$8b of customer's deposits as his slush fund.
I've heard a lot of wild conspiracy theories, but that one is new to me. To be fair, I do not believe the conspiracy theories, just that the inaction we're seeing is feeding credibility to the people peddling them.
I think that donating money one time buys you a photo. I think donating every cycle and especially anticipated into the future buys you access - which is correlated but not the same as outcomes.
> Why else would anyone give that kind of money to politicians without expecting something in return?
Because they think the candidates they support will make the world better either personally for you or in a more general sense? Oil companies give money to manchin because they know he agrees with them and if he wins will fight for their legislation, whether they funded him or not.
> Oil companies give money to manchin because they know he agrees with them and if he wins will fight for their legislation, whether they funded him or not.
Neither they or you know that. And nobody but you assumes that Manchin fights for his beliefs, rather than for what benefits him personally. And no, I'm not assuming the opposite. I instead choose not to fantasize about his internal states, or speculate about what he would do if an industry that has always supported him ceased to support him.
>Why else would anyone give that kind of money to politicians without expecting something in return?
There's a polite theory it is done for altruistic reasons to make the country a better place for all and that it is the exercise of free speech and you are also free to give Trump, Biden, Pelosi & McConnell vast amounts of cash.
It’s unclear to me how that affects anything? If anything it lends credence to the idea that he was making these donations solely for special favors and not for altruistic reasons.
Not just the democrats. Republicans, Bahamian officials, members of the media, regulators, etc. The most recent New York Times piece did not mention fraud or criminality a single time, painting SBF as someone who simply got in over his head.
Yes, it was fractional (in the sense there wasn’t enough gold to redeem), but the peg held. Economies grow much faster than gold reserves! The US still has the most gold in the word by a vast margin.
the ironic thing is that the US did tons of direct check-type helicopter money and yet our growth is healthier and more robust than anyone else in the world (and the dollar has also outperformed).
given other countries did not undergo similar fiscal programs and have faced similar levels of inflation, i would argue that the larger component of inflation was the sudden global start-stop supply-chain shock from the pandemic rather than purely excess demand from the too-large fiscal programs. and i do not consider that shock to be self-inflicted (tho the excessive fiscal spending certainly was).
When I hear it from business leaders, there are three logical reasons 1) exposure to the housing market 2) poor performance by the company (its the economy's fault!) or 3) an excuse to trim fat from a high-margin company that's aware of how bloated it is.
I have two kids under two. It's tough, but i dont personally know any parents that don't have a ton of fun with their kids. I love spending time with my 2 year-old. We have tons of fun together (like many 2 year olds, outside activities are a must). I'd rather be with him than any of my friends or other family and wouldn't trade it for the world.
