I like this heuristic, and have a few which are similar in intent to it:

 Hiring efficiency:

How long does it take, measured from initial expression of interest through offer of employment signed, for a typical candidate cold inbounding to the company?

What is the *theoretical minimum* for *any* candidate?
How long does it take, as a developer newly hired at the company:

* To get a fully credentialed machine issued to you
* To get a fully functional development environment on that machine which could push code to production immediately
* To solo ship one material quanta of work
How long does it take, from first idea floated to "It's on the Internet", to create a piece of marketing collateral.

(For bonus points: break down by ambitiousness / form factor.)
How many people have to say yes to do something which is clearly worth doing which costs $5,000 / $15,000 / $250,000 and has never been done before.
How long would it take an employee, utterly convinced that the CEO needed to know a material fact urgently, to communicate it to the CEO.

How long would it take the CEO to acknowledge receipt. (Would it be by their designate?)
Given that you have the full name of a coworker, how long does it take to determine:

* who their manager is
* what their title or role is
* what their primary project as of today is
Everything breaks and the world is on fire.

How long:

* Until the first responder responds
* Until the second responder responds
* Until someone says the local equivalent of "I am in charge of the incident."
A coworker is in obvious distress for uncertain reasons.

How long until someone offers to help?

How long until someone factually helps effectively?
An idea is floated for a new business unit / product / whatever the local equivalent is given company/industry/stage.

How long until it launches into the hands of customers who perceive it as a generally available offering?
How many keystrokes would be required to do an A/B test of the H1 on the homepage?

How many minutes from first keystroke to first person seeing it in production?

(I'm being very generous to the software industry here. *sigh*)
How long does it take an email from an unrecognized email address to the most generic tier 1 support alias to reach a senior responsible engineer / lawyer / executive given clear relevance to them?
What percentage of emails which an omnipotent, benevolent deity would route to a senior responsible engineer / lawyer / executive factually make it from tier 1 customer support to a senior responsible engineer / lawyer / executive?
You might sensibly read these heuristics and think "Hmm, you seem to over-focus on speed. Aren't quality, price, etc also really important?"

These questions don't *really* test for speed. They test for *repeatable competence at scale*, which is another thing entirely.
Incidentally these make good questions to get informal reads on companies and/or fill the "So, any questions for me?" part of interviews, because they're much more specific than "Do you like working here?", less likely to elicit social desirability bias in answers, etc.

One of the big promises of software is composability. You can build rich, powerful experiences out of basic building blocks.

APIs add new things to the toolbox. For example: Treasury, which lets an app/platform store, move, and track a business’

I've been a small business owner and can talk at length about SMB banking, and will later, but let's put on the software developer hat right now.

Lots of software talks about money, keeps records about money, does calculations about money, but can't *touch* money.

This is extremely frustrating when you're building SaaS apps for businesses, because you have total control over your UX right until your app needs to touch money... at which point all data about it lives in a silo you can't access.

So you generally push work to the operator.

For example, suppose you’re writing a business-in-a-box system for electricians, including an invoicing feature.

You need to be able to read bank transactions to reconcile. You probably can't. The owner can. So you ask the owner to do mind-numbing work a computer does better.

It sure would be great if your business customers had bank accounts you could actually introspect and operate on their behalves! You could just get the list of incoming payments and match against the invoices.

There is some software to write but it is not rocket science.

The payments wars in Japan are heating up and one of the battlegrounds is convenience store coffee.

“Coffee? What does that have to do with payments?” I’m glad you asked.

Convenience stores are low net margin businesses, which sell some high gross margin goods/services but a lot of low ones, and have high fixed costs and a low ticket size. The typical transaction is under 500 yen ($5) and many are about $1.

They need repeat custom.

A few years ago, all of the chains had a good idea for increasing frequency of use: make a minor capital investment in automatic coffee machines. Sell access to them for the price of a cup / ice; customers self-serve with the machine.

The price point is $1 to about $2.

Coffee quickly became one of the most frequently repurchased items at convenience stores, in no small part because it’s the one thing they can sell which is phameceutically habit forming but totally unregulated. (Just telling it like it is.)

But the coffee is not very defensible

The problem, such that it is, is that competing chains are everywhere and *all* of them serve Thoroughly Adequate Coffee at similar prices, so you’re back into the brutal economics of “Who is 3 meters closer to 40 customers at 1 office?”

Enter payment apps.

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

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.

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.

How you can filter stocks for Intraday trades - 🧵

As a kid, we would do homework before school the next day - you have to do homework here too. A specific sector performs on a particular day and studying things a day before will help you spot that particular sector. (1/11)

To prepare for the next trading day, you got to check the Index charts of all sectors. You got to keep an eye on a specific Index if you see a few factors:

- If any Index closed exactly at the resistance, you can get a trade on either side on the next day. (2/11)

- If it gave a rejection candle at resistance.

- If any Index closed exactly at support, you can get a trade on either side the following day.

- If there was a bullish signal at the support.

- If any Index gave a breakout or breakdown and then gave a good closing. (3/11)

- If any Index has taken support at 50 or 200 EMA.

Once you spot the Index, look at all the stocks in that particular Index. Pick at least 3-4 stocks from that Index and add them to your watchlist for the next day. It's ideal to check both higher and lower timeframes. (4/11)

What you should do next day? (When I am unable to check Indices and stocks a day before, I sometimes directly start with this process.)

- Start with checking the top gainers/losers list. I observe market from 9:15 to 9:45am to check the sectors performing well on that day.(5/11)

So when it first appeared in Normandy, the Sherman Firefly and it's meaty 17 pounder represented an ideal combo of reliable chassis, great gun and devastating firepower right?

Ummm...

Truth is a bit more complex. /1
#WW2 #SWW #History


Deliveries of Firefly to units only commenced in April 1944,
just a few weeks before Overlord & left minimal time for familiarisation.

Armoured Regiments mostly utilised Fireflies on a basis of 1 per troop of 4 tanks. /2


Finally each armoured regiment troop had access to integral, meaty, anti-tank firepower capable of dealing serious damage to any German AFV likely to be encountered. /3


The dual purpose 75mm gun was quite capable of laying down a reasonable HE shell or AP round for dealing with Panzer III or IV.

Firefly's 17 Pounder had.... problems with HE, but excelled at tank killing. So Tigers and Panthers would need to be wary. /4


Firefly's design history dated back to March 1943 when the General Staff published "Policy on Tanks" which effectively stated the majority of tanks should have a good HE weapon and...

Dear fellow musicians, performers, technicians etc. Here’s a thread about how our lives are going to change re touring/working in the EU in 50 days time. Think of it as a kind of Bad News Advent calendar. Here goes 1/

First things first, you’ll need a passport with at least 6 months left on it. And you’ll need full travel/third party/health insurance, since if you get ill or have an accident every penny of your care will have to be paid for 2/

To work or do a gig you’re going to need a work visa, just like you do for the USA. But here’s the thing. Work permits & visas and the conditions attached are a matter not for the EU but for the member states themselves 3/

Yes, every member state controls who comes in and who doesn’t and what the rules will be for work and residency. It’s almost as if the Brexiters have been lying about this ALL ALONG. EU members CONTROL THEIR OWN BORDERS 4/

So you’ll need to get a work permit for every country you’re intending to work or gig in and the rules are often different, as are the rules on eg taxation of that work (eg Spain has a withholding tax, France does not) 5/

1) The Temple of the Divine Claudius was a vast temple complex on Rome's Caelian Hill, overlooking the valley that would later be occupied by the Colosseum. Though almost nothing now remains of the structure, its scale and grandeur once rivalled anything in the city.. #LostRome


2) The 'Claudium' was intended as a sacred complex to revere Claudius and the imperial cult. Construction began soon after the death and deification of the emperor in 54 AD, initiated by his widow Agrippina who was likely responsible for his supposed death by poisoning. #LostRome


3) The sprawling temple complex sat on a gigantic podium that spread across the Caelian Hill, measuring 180 x 200 metres; with towering retaining walls of travertine that raised the structure 20 metres above the valley below. #LostRome


4) The elevated sacred area was likely entered by steps facing the temple on the west side. The temple itself had a projecting hexastyle porch and was surrounded by gardens and a grand portico, probably the 'porticus Claudia' mentioned in Martial's 'On the Spectacles'. #LostRome


5) Statues of both Agrippina and Claudius’ ill-fated young son Britannicus, sculpted in sumptuous dark Egyptian greywacke, were discovered among the ruins on the Caelian Hill in 1651 – and had almost certainly been displayed in the temple precinct. #LostRome

This day was inevitable. Indian Muslims always lived in La La Land. They bad mouthed real well wishers & slept with the enemy who never considered them as part of them. In Gulf, Indian Muslims were busy with Javed Akhtar & Sonu Nigam. Never interacted with South Asian diaspora

Now when Indian Muslims are thrown to wolves it’s Pakistani & Bangladeshi Muslims with whom they kept distance are the only ones feeling their pain. None of the people who they invited for Eid Milan. Qawali & Mushaira are there for them. Such people invoke wrath upon themselves

Indian Muslims never spoke for Kashmiri Muslims. Distancing from separatist was understandable but we never even bothered to highlight their human rights violation & rapes carried out by forces. We could have sent them humanitarian help we didn’t. Our silence made us complicit.

When Sania Mirza married Shoaib Malik it was something legal. A Muslim married another Muslim. Entire Hindutva media went after her. They launched a witch-hunt for months. No Indian Muslim stood by her. All were silent. Now days come when Muslims are arrested for marrying a Hindu

Indian Muslims particularly the elite downplayed communalism in India by saying it will pass or Hindu majority is good. Fringe are bad. They misguiding others. Muslims were always others. Indians were happy to see Muslims sing & dance & eat their food but never considered as own
