mathattack··on Red Hat cutting hundreds of jobs, CEO says in letter to employees
Keep in contact with everyone who thinks highly of your work. A strong recommendation (“you must hire person X, they’re perfect”) is the best defense against age discrimination. You can’t help it if your employer moves your job to India. You can lay the ground to make the transition faster.
mathattack··on Red Hat cutting hundreds of jobs, CEO says in letter to employees
Welcome to life under IBM. They’re in the business of a financially engineered shrinkage. This is what happens when innovation and growth stops.

What you see from IBM:

- Cut expensive (old) employees.

- Market everything as the New thing. (Watson)

- Audit your customers. Settle by forcing them to buy the New thing even if they don’t need it.

- Current and former execs go on book tours.

- Buy back shares.

This is all rational when you can’t put capital to good use anymore. It just sucks to be a customer or employee of them.

mathattack··on FerretDB: open-source MongoDB alternative
Probably a huge cost savings to turn off Al those MongoDB nodes.
mathattack··on 3 years after Sprint merger, T-Mobile employs 9k fewer people
I guess it’s all semantics to me, as when I read “merger“ or “merger of equals” there is usually a dominant partner. Either way it gets to the end you’re pointing at. Less need for excess sales, support, etc.

I see this in some acquisitions too. (Like when IBM buys anyone)

mathattack··on 3 years after Sprint merger, T-Mobile employs 9k fewer people
How many people were at YouTube and Instagram before their mergers?

It all depends on the stage of the companies. When companies are still in growth mode it can create more revenue and jobs. When companies run out of ways to grow (mature industries like telecom) then mergers are almost always about economies of scale and cost savings.

mathattack··on The Kissimmee River has been brought back to life, and wildlife is thriving
I’m curious on the economics of this. Sounds like a billion dollars to reclaim 20 square miles. How many more square miles are still to go?

What was the benefit of draining it in the first place, and who received that benefit?

Awesome - thanks!
mathattack··on ‘Alien calculus’ could save particle physics from infinities
Thanks! Would you be aware of any kid-friendly sources that could be used to inspire students? Of the “We love calculus because it explains how a ball moves. Now let me show you something really cool!”
mathattack··on How to be a -10x Engineer
Yes. Disorganization is the largest cause I’ve seen of preventable waste.
mathattack··on Lyft Hires New CEO as Founders Step Back
Seems like they took the foot off the gas over the past year and let Uber push them around. It’s hard being number two in a “winner takes all” market with such strong network effects.
mathattack··on Google was beloved as an employer for years. Then it laid off thousands by email
Part of the reason the average tenure is so short is companies usually quote Median, and that’s low by definition in high growth companies. If you double your headcount in 2 years, your median will be less than 2 years even if nobody quits.
mathattack··on SVB Hall of Shame
The VCs did what they had to do. It’s poor financial management to not run for the door when the last one standing may be holding the bag.

I just find it strange that after all that SVB is using the bailout as marketing. “All your new dollars are safe too!”

mathattack··on How Silicon Valley Bank Avoided Oversight
These aren’t engineers running the bank. It was always Finance people. They understood the concept of bond duration (interest rate sensitivity). They just made a calculated bet on interest rates to goose their bonuses.
mathattack··on Stripe announces new round of funding and plan to provide employee liquidity
I think it’s more nuanced. The issue bigger than market cap is just being able to IPO at all and give your folks liquidity.
mathattack··on Silicon Valley Bank unmasks the hypocrisy of libertarian tech bros
SVB failed because of an interest rate bet gone bad. If they invested in short duration treasuries instead of long duration, none of this would have happened. The main difference is their bonuses would have been lower the past few years.
mathattack··on SVB shows that there are few libertarians in a financial foxhole
They chose to. They didn’t need to. If they were getting too many deposits, they could lower the interest they paid on them.

The problem is they bought a bunch of long dates securities yielding 1.5-2% and when the deposits flooded in they started paying more than 1.5-2%.

They have been better off buying T bills or something else without duration risk and paying something less than Fed Funds. This is what most banks do.

mathattack··on SVB shows that there are few libertarians in a financial foxhole
It’s not a matter of being prescient. They made an explicit bet. “Rates won’t go down, so let’s get as much yield as possible via long term securities”

They could have just as easily done what most other financial institutions do: match the duration of their liabilities with the duration of their bonds. If people can quickly pull their money, then keep the money in short term bonds and money market funds.

The problem with that is it’s harder to make big bonuses when you’re being fiscally conservative.

mathattack··on SVB in talks to sell itself after attempts to raise capital fail
SVB wouldn’t have these issues if they monitored the risk better. If they put the money in short term govt bonds they would be fine. Or if they kept the rates they paid on deposits low to discourage the excess, they would also be fine.

Banks are in the business to manage risk.

The sad part is this risk management and investment process is concentrated in a very small group. Most of the bank employees are very good, had no idea what was happening, and some will lose their jobs as their equity goes to zero.

Or for Athletic Greens. :-)
mathattack··on Airbnb nightly rates shot up 36% in 3 years
Same issue with airlines and aggregators. No way to know the true cost on Travelocity until you’ve finished the purchase.
mathattack··on GitHub staff are required to use Teams by Sep 1, 2023
Seems natural to be forced to eat the owners dog food. At least they don’t have to deal with the Microsoft sales reps.
mathattack··on Small SaaS banned by Cloudflare after 4 years of being paying customer
Imagine their size and market cap if people could trust their Sales organization.
mathattack··on Small SaaS banned by Cloudflare after 4 years of being paying customer
My experience with the Cloudflare sales team is they were woefully disconnected from any ability to make good on their promises, and that it didn’t matter to them at all. It was a strange narcissism -bit wasn’t that they were deliberately lying, it was as if the notion of truth and lies didn’t matter. That if they kept blabbering assumed that they’d get the sale.

In general you can’t trust salespeople and need to get everything in writing. Cloudflare is a prime example of why.

And I’d add in my case because we were keeping track of their promises, we caught them before the sales process completed. It cost them seven figures a year. But maybe it doesn’t matter - their sales approach still has them worth $20 billion.

mathattack··on Where our gasoline comes from
Prices of commodities are global if they can be shipped. Gold has only one price. There’s no difference in a Bitcoin price if it’s mined in the US versus abroad.
mathattack··on Ask HN: Why Is Everything Declining?
When I see posts like this I think “How would I measure this over time?”

Software projects were notoriously late and brittle in prior eras. (Ask anyone supporting a mainframe that they’re afraid to reboot)

Fraud and monopolies are as old as money. (Look up the history of Wall Street and railroads)

It’s very hard to come up with good time series data so here is my wish list to test the “we are going to crap” hypothesis:

- Air Quality Index over time.

- % of the World Population with sub-0 net worth over time.

- % of World Net Worth in discovered financial crime.

- % of technology projects overbudget and overdue weighted by dollar value over time.

- % of population literate.

Some these are hard to measure. I’m open to other measures. Absent that it’s about as accurate as asking someone “Are you busier than you were 20 years ago?”

mathattack··on Stripe sets one-year timetable to decide on going public
The use I’ve seen in the vernacular is “what are the cash flows worth on their own?” (Discounting back the future ones adjusted for risk) Sometimes people state they know it with confidence, but it’s subjective too (the science on discount rates and predicting growth is a lot weaker than Physics).

It leaves out things like “what might the IP be worth to someone else?” and “What could the company do with better management?”

To your point, it’s frequently less than what the company trades at. Sometimes the opposite is true, and the company trades for less than the cash value of its assets minus liabilities.

mathattack··on Stripe sets one-year timetable to decide on going public
Intrinsic value involves discounting future cash flows. With rates up that should punish Stripe similar to the rest of the market.
mathattack··on PagerDuty to Lay Off 7% of Staff; Revenue Officer to Exit
I wasn’t a fan of their Oraclesque sales techniques. They have a lot of customers waiting for them to fail.
mathattack··on Ask HN: What do you do to start and develop friendships?
Almost exclusively through school, work, shared hobbies and volunteering. As I age through my kids friends too.
mathattack··on CEO Jack Altman’s email to Lattice employees
Id like to see Lattice work on the usability of their product as well. If they don’t fix that the other 85% of the company will lose their jobs too.
