jalayir··on Why does sorting in computer science mean ordering rather than categorizing?
Ordering is just a special case of categorizing.
jalayir··on Ask HN: Why does P2P encrypted messaging still suck?
I think part of your question is, why does every p2p app not work on all platforms equally well. This is true of pretty much 90% of apps and software - they don't work on all platforms equally well. This is because of conscious design and business decisions taken by the builders.
jalayir··on Norwegian Shipbuilders Turning to Battery Power
The decks are stacked up with containers. No room for sails
jalayir··on Repairing the card reader for a 1960s mainframe: cams, relays and a clutch
The prices of modern appliances have come down due to really intricate miniaturization of many components, which enables larger scale manufacturing and cheaper supply chains.

Because of the prices being low, it's not really worth it to repair consumer goods anymore. And if it's worth it in some cases (iPhone), it can only be done by a specialist due to the extreme miniaturization.

jalayir··on Lessons from France's first cyber-attack, nearly two centuries ago
Yeah that was classic Man-in-the-Middle attack.
jalayir··on PostgreSQL 10 Released
Have your run ANALYZE? ;)
jalayir··on Fast food and obesity in developing countries
> The big Mac will constitute nearly 50% of calories in a meal

The big mac in India is chicken, and a lot smaller. Edit: Also, it's called The Maharaja.

jalayir··on A 400-year story of progress – How America became the world’s biggest economy
India is hardly resource rich. Especially not per-capita.
jalayir··on Hunting for a Canadian Legend: The Avro Arrow Jet Fighter
Wow looks a bit like the venerable MiG-25 foxbat
jalayir··on Reported difficulties getting help on Equifax's phone lines
Equifax worked, the other two failed for me
jalayir··on What the Industrial Revolution Tells Us about the Future of Automation
You also missed out violence inflicted on colonies, in Asia and Africa.
jalayir··on Sundar Pichai Should Resign as Google’s C.E.O
The big assumption in David Brooks' piece is that the so-called "manifesto" was Damore's one and only "transgression". Were there other, previous internal complaints about him, and this was the straw that broke the camel's back?
jalayir··on India wasn't the first place Sanskrit was recorded – it was Syria
In the article, the author clearly provides clickable references in the form of hyperlinked text. I don't think he claims "he dug the proof himself".
jalayir··on Show HN: An interactive guide to compression basics
The first example (tree represented in Japanese) seemed a bit misleading, because the "alphabet" has not been kept as a constant. Since the Japanese alphabet is much larger, it may be argued that the number of bits actually occupied in storage by "本" and "tree" are about the same. Could someone clarify if this is correct reasoning?
jalayir··on Why we should learn German
Mr. King sounds like inspiration for some part of George Smiley's character.
jalayir··on Say Goodbye to Spain's Three-Hour Lunch Break
Yes, in India, shops don't close in the middle of the day. But business is very slow during those few hours.
jalayir··on Ask HN: Do you think career and family is either-or?
I think every story is different, and it all depends on the individual circumstances. I worked for a startup where the founder was a "family man" - with an extensive family, and he was doing great at work afaik. Wasn't sacrificing much on either front. He did have to employ a part-time nanny, to free up time for his wife and himself could both simultaneously have good careers.
jalayir··on California solar power output sometimes exceeds predictions
Could excess power from CA be exported to Mexico or Central America?
jalayir··on The Bibighar Massacre: The Darkest Days of the Indian Rebellion of 1857
Yes, but they did hold a lot more of Afghanistan than the British.
jalayir··on The Bibighar Massacre: The Darkest Days of the Indian Rebellion of 1857
> there never was one power that controlled the whole subcontinent

There were several - indeed, the British had it easier because the Mughals had dissipated within living memory, and all their bureaucracies and systems were still functioning.

jalayir··on Ask HN: Why shouldn't I leave Google?
> My mentor suggested to stay at Google until I find an interesting startup idea to work on.

This is a sound piece of advice.

However, it looks like you're very keen on traveling. Maybe you can take a 3-month unpaid sabbatical from Google, and see what it feels like?

jalayir··on Sand and gravel mining “greatly exceeds natural renewal rates”
Not really. You can't use just any soil for construction, it has to be a sandy/grainy variety.
jalayir··on The Higgins Boat: Wood, Steel, and Purpose
> Almost everything the Soviets built

The T-34. The epitome of sound, sensible, pragmatic engineering.

jalayir··on AWS Training and Certification Portal
Do you mean the ones who are actually employed by AWS, or anyone who works as a Solutions Architect focussing on using AWS technologies?
jalayir··on Engineering management lessons (2014)
> lowering our bar for hiring

Let me guess, Amazon?

jalayir··on Wipro, Infosys, Tech Mahindra, Cognizant Slash Jobs
Not sure about the quality of this piece. One company, Cognizant, is obviously in some form of trouble. The others are laying off a few hundreds/thousands jobs, on a base of 100K+ employees, as part of the performance review process. There's also no mention of hiring being reduced for any of these companies.
jalayir··on Data Science Workflow: Overview and Challenges
Do a lot of these "data quality" problems go away if you were simply to use a relational DB, and related best practices, like table versioning, PKs, using a last_updated timestamp for each row, etc.?
jalayir··on Consider a Dell Optiplex FX160 Instead of a Raspberry Pi
The hackability of the GPIO pins is what keeps me going back to Raspberry Pi.
jalayir··on Maintainers make the world go round: Innovation is an overrated ideology
> Maintenance is something very, very specifically Western

Not really. The need for maintenance occurs when a specific "Thing" has been around for long enough, and when the institutions, schools of thought that sustain that Thing persist for long enough. When there are radical, rapid political/economic/political changes, "maintenance" and the need for maintenance goes away. This article focusses on maintenance of industrial artifacts, and nowhere in recent times have industrial artifacts (boats, lifts, software), the companies that produce them, and the living standards they create, and the governments that encourage them been continuously existent longer than the "Western countries" (since the early 1800s at least). If you were to look outside the sphere of industrial artifacts, for example at old religious buildings - churches, mosques, temples - you'll see solid examples of good maintenance all over the world. The Koran, a literary artifact, for example, has been well-maintained for over a thousand years across the world by a mostly pre-industrial society.

TLDR: Keeping something running isn't just a "Western" thing - but keeping industrial products running is certainly Western, because only the West has seen a continuous and sustained industrial movement for over 200+ years.

jalayir··on SQL is 43 years old – Here’s why we still use it today
> What _are_ the "correct" use cases for NoSQL?

When you need a highly available and reliable DB for your application, then you need a cluster approach for data replication. Most popular SQL DBs are single-node, with some application-level clustering solutions, so the only option is to scale vertically. However, a lot of no-SQL DBs like Redis and DynamoDB do clustering/replication closer to the iron.
