cliftonk··on 10Gb/s Ethernet: switching to a Broadcom SFP+ module
i have gfiber 8gb put in my house. a cost-effective high performance setup im using is unifi cloud gateway fiber + 2x microtik CRS305 SFP+ (for all my other 10G devices) + 2x unifi flex 2.5G. this setup gives me a lot of 10G ports for little cost. copper DAC cables are great (optical transceivers and cables also work for longer runs). another great hack for older houses is using goCoax MoCA 2.5 Adapter to run 2.5G around the house via coax cables to your wifi access points.
cliftonk··on Migrating from Go to Rust
I have preferred rust for many years now, but we’ll be using models spitting out 500-1500 or more tokens/sec soon and rust compile times are glacially slow (while go is almost instantaneous).
cliftonk··on Show HN: rstructor, Pydantic+instructor for Rust
sure. could definitely add that if someone needs it. thx for sharing!
cliftonk··on Show HN: We made a small and cheap network switch
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)
cliftonk··on Smart Contract Security Field Guide
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?”

Please stop upvoting this comment.

cliftonk··on Rivian R1T Fender Bender Turns into $42,000 Repair Bill
I once had a fender bender in a Tesla that cost 20k to fix (back in 2016). Downside of not having 3rd parties making the parts.
cliftonk··on How tech’s defiance of economic gravity came to an abrupt end
Most of the losses were from earnings multiples reverting back to historical norms… which is healthy.
cliftonk··on Sam Bankman-Fried tries to explain himself
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.
cliftonk··on Sam Bankman-Fried tries to explain himself
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.
cliftonk··on Sam Bankman-Fried tries to explain himself
to be clear:

- 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.

cliftonk··on Money Creation in the Modern Economy – Its a Wonderful Lie
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.
cliftonk··on Bank of England expects UK to fall into longest ever recession
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).

cliftonk··on US economy returned to growth last quarter, expanding 2.6%
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.
cliftonk··on 75% of the time we spend with our kids in our lifetime will be spent by age 12
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.
cliftonk··on Cloud services like AWS or Google Cloud Platform may be the wrong choice
I generally agree that no one that isnt a professional devops person (or has spent months tuning IAM and route53 policies) should be using AWS. That said, GCP is so much easier to use and easily usable by a novice because it has a lot of good defaults.

Compute and egress costs can be prohibitive at scale, but features like storage + bigquery (OLAP SQL db where u only pay for queries) are basically free for low-to-moderate volume workloads.

cliftonk··on Ask HN: 10k hours rule to master anything. Could I switch career when I am 43?
Sam Walton was about 45 when he started walmart. I've made career pivots several times, most recently this year, at age ~39. Just do whatever you're interested in... major pivots require the willingness and stamina to drink from a firehouse, so keep that in mind.
cliftonk··on Helium, Pump and Dump
so far as distribution, 25% to early investors and founding employees seems pretty close to market. a "pump and dump" would insinuate that founders/other management sold significant holdings during the run-up and made fraudulent claims about the business (they might have! but you arent providing evidence of that).

as for early investors, there is absolutely nothing wrong with those folks selling any amount of their stake as it becomes liquid. i generally agree it is scammy to give early investors short lockups on these token launches.... but the reality is that many of these projects do have short lockups and that should be part of your DD as an individual investor if you're investing in crypto.

cliftonk··on Tether ordered to produce documents showing backing of USDT [pdf]
definitely agree that if there were a ~50% depeg in tether things would get very, very ugly in crypto
cliftonk··on Tether ordered to produce documents showing backing of USDT [pdf]
They would be paying CP issuers with USD out of a bank account (the same USD used for creation/redemption of USDT).
cliftonk··on Tether ordered to produce documents showing backing of USDT [pdf]
and btw there are liquid tether credit risk products you can trade if you believe that tether is going to collapse that cost around 20bp / month (so something like 40x payout on annualized premium if tether goes to 0).
cliftonk··on Tether ordered to produce documents showing backing of USDT [pdf]
Virtually every take I read on this forum is uninformed. To hear it straight from the horses mouth, here's Matt Levine + SBF getting into the realities of tether (skip to 48 minutes): https://open.spotify.com/show/1te7oSFyRVekxMBJUSethH?si=05bd...

I agree with the general sentiment around tether acting very opaque / shady. That said:

1. creation/redemption of tether (read: actual USD wire transfers) has been done on the magnitude of billions of dollars a time by major players in the space

2. during UST collapse, something like $15b of tether was redeemed in less than 2 weeks. so they obviously had that much cash on hand at the time.

3. the academic paper that attempted to show that tether was being created to pump up bitcoin has an extremely simple alternative explanation: as bitcoin went up, holders of bitcoin sold it for tether on centralized exchanges on the way up.

so, IMO they could very likely have some bad commercial paper on their books, but i think its much more likely than tether is worth 90 cents on the dollar and not 0, and in the case that it is worth 90 cents on the dollar, it would be extremely likely to continue to trade at par as there's very unlikely to be a scenario which forces any kind of large-scale redemptions.

cliftonk··on Dark Moon: The Inevitable Collapse of Luna
You deposit USDC as collateral into dydx (or another derivatives exchange) and then you go short the perpetual (kind of like a future). I made 150% on my account equity shorting Luna when UST fell under 0.95.
cliftonk··on UST Stablecoin Loses Dollar Peg
ethereum is changing its consensus mechanism to PoS later this year. when it does that, the only major PoW chain left will be bitcoin. all other smart contract chains with large userbases are PoS already.
cliftonk··on Psychic Signatures in Java
That’s all true, but fuzz testing is very effective at checking boundary conditions (near 0, near max/mins) and would have caught this particular problem easily.
