Torn between "I think losing $100 million when someone beats you at security research is pretty much exactly what you signed up for doing yield farming" and "Maaaaaaaybe not the future of finance you were expecting, huh."

 How to put this in regular finance terms...

Suppose hypothetically you have an account at a brokerage with some valuable asset in it. You take a margin loan against that asset to fund your normal spending, or pay a tax bill, or maybe buy something at another brokerage.
For reasons known only to the brokerage, they don't denominate your loan in dollars. They denominate it in shares of a money market fund, which are worth $1 +/- epsilon and basically never deviate from that.

And you think "Hmm, I have a large equity cushion against this loan."
One day, a computer system at the brokerage reports, sorta-kinda erroneously, that the value of the money market fund is actually $1.30 per share. The equity cushion is gone. Your valuable asset is sold, at timing you didn't choose, at wrong price, to pay an inflated phantom debt
And your recourse is... probably tweeting at patio11 saying he finds too much joy in this.

Which I don't; I just feel like this is why you don't trust a CPU built out of redstone to build reliable financial infrastructure on top of.
"Hey patio11 could this happen in traditional finance?"

Ill-timed liquidations can and do, but attacking someone doing something not-risky to force a liquidation is harder, because of many built in safeguards.
One, you can actually borrow in your unit of account (e.g. dollars), and $1 = $1, so you can't convince a brokerage that a $100k debt is actually $130k.

Two, if you regulated financial institution has a goof in your data feeds causes you to mechanically disadvantage retail...
... your most likely outcome is having an internal meeting and saying "Which do we dislike more, covering their losses out of our equity OR getting our knuckles rapped by the regulators, paying a fine, then covering the losses with our own equity?" and choose door #1.
Three, it is enormously hard to pervert the most popular real markets in the world and that is a game you actually don't want to win, because the first prize is frequently go-directly-to-jail.

This is not the consensus viewpoint among engineers, who do not have good calibration.
Like if you somehow did security research against e.g. the monthly Treasury auction and somehow caused it to invert expectations around reality, that would plausibly have $X0 billion in consequences and you could make out like a bandit.
And also literally everyone you had talked to for the last several years would be taken out for tea by friendly serious federal agents.
("Do you really think that would happen?"

For the treasury auction? Oh heck yes I do. Expect a turf war between the money people and the terrorism people over who gets to lead the investigation.)
Crypto enthusiasts would probably suggest me to disagree with them on this, and I actually do not at all:

The financial system is in part of broader systems of state control. Seriously attacking it at scale would be treated indistinguishably from "kinetic" war.
"So is the state going to seriously come after crypto people then?"

While they flatter themselves into thinking they materially challenge the government, following their own logic pretty closely, if this were actually true their conferences would attract precision munitions.

There are a *lot* of software shops in the world that would far rather have one more technical dependency than they'd like to pay for one of their 20 engineers to become the company's SPOF expert on the joys of e.g. HTTP file uploads, CSV parsing bugs, PDF generation, etc.


Every year at MicroConf I get surprised-not-surprised by the number of people I meet who are running "Does one thing reasonably well, ranks well for it, pulls down a full-time dev salary" out of a fun side project which obviates a frequent 1~5 engineer-day sprint horizontally.

"Who is the prototypical client here?"

A consulting shop delivering a $X00k engagement for an internal system, a SaaS company doing something custom for a large client or internally facing or deeply non-core to their business, etc.

(I feel like many of these businesses are good answers to the "how would you monetize OSS to make it sustainable?" fashion, since they often wrap a core OSS offering in the assorted infrastructure which makes it easily consumable.)

"But don't the customers get subscription fatigue?"

I think subscription fatigue is far more reported by people who are embarrassed to charge money for software than it is experienced by for-profit businesses, who don't seem to have gotten pay-biweekly-for-services fatigue.

If an employer is willing to be abusive to you prior to hiring you, when you have maximum leverage and they are maximally incentivized to play nice, I think that gives you *extremely actionable* signal as to how they'll treat you when you're working there and dependent on them.

For candidates: evaluate prospective employers accordingly.

For startups employing e.g. engineers: given that your candidates should evaluate you accordingly, be *extra special* careful to operate like professionals with regards to e.g. interviewing, offers, and negotiation.

"Can you be more explicit about 'abusive' here?"

Not without violating a confidence, but as someone who has been on hiring side of table and is a capitalist, there are *clearly* things you could do which would be "sharp operating, but we're all sharp operators" in some contexts.

Hiring employees is often not one of those contexts. The nature of the relationship, the asymmetry in power, and the social contract strongly counsel you to be a lot better there than you are minimally required by law / contract.

A thing which aesthetically frustrates me is that a lot of the things I've heard companies do here serve *no legitimate business purpose.* In some cases it's getting tens of dollars of advantage. TENS! On an engineering candidate!

It’s underremarked upon that stablecoins accomplish basically all of the original design goals for Bitcoin qua a transactional mechanism (instant free value transfer anywhere), but that nobody cares about this because nobody ever cared about that part of the pitch.

“Why do people care about stablecoins then?”

A mix of “they encourage dollar-denominated liquidity in the cryptocurrency ecosystem and discourage withdrawal of the same” and “they’re good for money laundering.”

“But they make value transfer between exchanges much faster!”

This was a solved problem in traditional finance, too, mostly through the extension of credit. (It doesn’t matter how long settlement takes if there is sufficient trust to enable credit.)

The Bitcoin ecosystem is *positively allergic* to credit, so you have to call it a coin for them to accept it. And after you call it a coin they ignore everything the world has learned about credit, like risk management.

“Stablecoins aren’t credit!”

They’re pretty much exactly credit? A tether is a zero-coupon Bitfinex bond with a non-functioning call option. I

FAQ: “How do I get better at writing?”
Me: Write a million words.
Follow up: “Hah but seriously.”
Me: Start with 20,000 words. Everyone gets to that 50 times in their first million.
Follow up: “No seriously.”
Me: Nobody expects 10 Quick Tips To Play Violin At Carnegie Hall.

The Internet is so much better at teaching writing than the traditional educational system principally because it removes an artificial and limiting constraint on output imposed by ability of gatekeepers’ limited time to evaluate output.

(Interestingly in fields where we actually care about performance we’re good at encouraging students to practice when no one is watching but for writing we basically assume all the value is created by the teacher-minute of attention. Teacher-minutes are scarce and rationed.)

If you ever want to be deeply, deeply disillusioned about the state of the world, compare what we do where we care about output quality and what we do where we don’t, and which domains sort into which column by revealed preference.

Bitfinex files discovery in "Yo bro, where did our $800 million go?" action and it is every bit as interesting as you'd expect it to

Here's their CFO describing their agreement (which we know from other litigation was never contractualized because, presumably because money launderers hate paper trails):


Bitfinex's CFO was shocked, shocked to learn that the money launderer they engaged to provide money laundering services while I-swear-to-God-this-is-an-actual-quote "we learned to bank like criminals" may have from time to time lied to banks.


"Institutional constraints" means, here, "We were attempting to avoid velocity checks placed by our banking partners to detect fraud and money laundering, which would have detected our fraud and money laundering."


Money at the speed of code, yadda yadda yadda, the Bitcoin economy is surprisingly blasé when several hundred million dollars is in an interstitial state for months.

In a situation never before encountered by a financial institution: the check was not, in fact, in the mail.

I think about this a lot, both in IT and civil infrastructure. It looks so trivial to “fix” from the outside. In fact, it is incredibly draining to do the entirely crushing work of real policy changes internally. It’s harder than drafting a blank page of how the world should be.


I’m at a sort of career crisis point. In my job before, three people could contain the entire complexity of a nation-wide company’s IT infrastructure in their head.

Once you move above that mark, it becomes exponentially, far and away beyond anything I dreamed, more difficult.

And I look at candidates and know-everything’s who think it’s all so easy. Or, people who think we could burn it down with no losses and start over.

God I wish I lived in that world of triviality. In moments, I find myself regretting leaving that place of self-directed autonomy.

For ten years I knew I could build something and see results that same day. Now I’m adjusting to building something in my mind in one day, and it taking a year to do the due-diligence and edge cases and documentation and familiarization and roll-out.

That’s the hard work. It’s not technical. It’s not becoming a rockstar to peers.
These people look at me and just see another self-important idiot in Security who thinks they understand the system others live. Who thinks “bad” designs were made for no reason.
Who wasn’t there.

A thread on HN about bad code in legacy projects both makes me think how little we've learned as a discipline over the years and, honestly, how little credit we give ourselves for some pretty major

Fun going down this list and thinking: "Hmm, plausible at a well-run modern software shop", "Hmm, possible, but requires implausible tradeoffs", "Literally disallowed by languages", and "If you were to attempt doing that our test suite wouldn't let you merge."

I think we as an industry celebrate (not quite the right word) failure too much and don't celebrate success nearly enough. There is no DailyWTF for competent execution, word of which generally stays pretty local to the source while incompetence passes into legend.

Alrighty let me try to thread the needle on being the change I want to see in the world while not giving away anything that will get me in trouble:

Ruby has wonderful developer ergonomics. Typed languages are easier for machines to guarantee the correctness of. We built a type checker for Ruby (and I believe it is slated for OSS release sometime).

🙋🏾‍♀️ In 2011, I was hired into my first junior role in tech @Groupon

👩🏾‍💻 By 2020, I was headhunted into a VP role in a global tech company @Brandwatch

🤖 I achieved this progression in less than a decade, without ANY coding skills

🔮 How did I do it?

*a thread*


🤓 I established a track record of results.

💪🏾 No magic formula can replace hard work: do your job well & hit all the targets you are set.

😬 When you're struggling, ask for help so you can stay on track to get results, or collaboratively adjust targets.

🎨 I stayed creative.

🧙🏿‍♀️ When challenges arose I was bold enough to try new solutions. Not everything worked, but constantly trying produced valuable innovations.

🧠 I was proactive in finding new, better ways to get the job done.

🤩 I was a self-promoter. I recorded my achievements & ensured they were mentioned in any performance / compensation reviews.

😎 I put myself forward for any opportunities to gain recognition e.g. speaking opportunities or awards.

👀I actively worked on gaining visibility.

🙂 I was myself. Some say you need to be ruthless to succeed. I don't buy it. I'm a nice person so I'm nice at work, too.

❤️ I didn't fake it. I always acted on my values, and spoke up when something didn't feel right. I showed integrity.

🤗 I was a team player. To everyone.

So we had to develop technologies like this to barely manage control over limited areas in Iraq's few urban centers. Only ~8 in 100 Iraqi adults owns a personal vehicle. That rate is > 1 car/adult in America yet I have never seen any doctrine paper or work of fiction address this


We've seen and struggled in civil conflicts with instant, local, universal, distributed communications (cell phone era, basically every conflict since 2000). We've seen and struggled in conflicts with instant, global, universal distributed communications (everything since 2011).

The world's most overfunded military and glow in the dark agencies struggle and largely fail to contain conflicts where fhe vast, vast majority of people are locked into a ~5mi radius of their home.

How can they possibly contain a conflict in a nation with universal car ownership and the most developed road network in the world? The average car can travel over 400 miles on one tank of gas, how can you contain the potential of that kind of mobility?

I think that's partially why the system was so freaked out by 1/6. Yes, most of it is histrionics but you don't decide to indefinitely turn your capital into the Baghdad Green Zone with fortifications and 25k troops over histrionics alone.

2) Porus ruled the Punjab region and expanded his kingdom between the Jhelum River and Chenab River in the Indian Subcontinent. He was a legendary warrior and more war skills. He made the army most powerful with war skills. Even Alexander had also made difficulty to defeat Porus.

3)Word of Mouth Oral tradition in #Mohyal_Brahmin families since ancient times has kept the Great Saga of their Great Elder known to them as Maharaja “ #Puru” alive.

4) When #Alexander the Great invaded India in 326 BC he was challenged near Taxila by a mere chieftain of the Area. He was King #Porus, a #Vaid_Mohyal. After his encounter with Porus, Alexander met with more resistance near Multan where the forces were predominantly #Mohyal.

1) “Eliminationism” is a term you need not just to become familiar with, especially in today’s American rush toward authoritarianism. This will be a long, illustrated thread explaining what it means, how it works, and why Donald Trump is now our Eliminationist in Chief.


Warning: Some images contain violence and are disturbing.

Also warning: This thread is ridiculously long. 75 tweets is insane. I apologize. But this stuff is important. I hope you find it compelling anyway. If not, I understand.

2) So, what exactly do we mean by “eliminationism”? Here’s the academic definition:


3) It was largely coined by Holocaust scholar Daniel Jonah Goldhagen in his 1996 book Hitler’s Willing Executioners, about the role ordinary Germans played in the Holocaust, which he described as fueled by “eliminationist antisemitism.”


4) The book describes how in reality the largest numbers of Jews and other victims killed by Nazi directive were rounded up and gunned down or immolated en masse and buried in mass graves by ordinary Germans and non-Jewish residents of German-occupied territories.

#TodayInHistory Ram Prasad Bismil,Ashfaqullah Khan and Roshan Singh are hanged in 1927, as they give up their life for the cause of freedom and inspire many a revolutionary. #LestWeForget


Shahjahanpur was a hub of revolution during the freedom struggle. Most of the revolutioaries in the North, were from this town. And among them, the most famous were two friends, whom destiny would bring together- Ram Prasad Bismil and Ashfaqullah Khan.

Ashfaqullah Khan was born at the turn of the 20th century on October 22, while Bismil was born 3 years earlier on June 11, in the same town. Both of them were excellent writers in Urdu and Hindi.

Both of them would come together under the Hindustan Republican Association, not to mention the fact that Ashfaq was an admirer of Bismil’s poetry, and became close friends with him on that account.

And both these men were hanged on the same date, December 19, 1927 for their involvement in the Kakori event. Two men from different religions, different backgrounds, yet destiny would bring them together.
