_callcc··on Update on Meltdown and Spectre
In the Spectre paper they note that while Chrome degrades the resolution of `performance.now()`, they were able to get a timer with sufficient resolution by using a Web Worker (thread) which repeatedly decrements a value in shared memory. As far as I know the EVM intentionally doesn't provide any concurrency because execution must be deterministic, and it seems doubtful that any kind of message-passing from outside the contract would be fast enough to provide the resolution needed.

However, the block-lattice cryptos like RaiBlocks that find a way to build in concurrency and shared memory might be different.

Yes, they would have been better off leaving out this "cycling" bit altogether.
_callcc··on The great error: the Bolsheviks were not a party but an apocalyptic sect
All these anti-Bolshevik treatises of late merely profit from the decay and ruin of Left-wing consciousness and culture that has taken place in the last century. The old Bolsheviks I once knew would have laughed at this "thesis". But who is around anymore to argue against it?
_callcc··on Why does American medicine still run on fax machines?
> Create a protocol or API spec on top of HTTPS or something else and use it.

This is basically what they've done with EDI/X12 over AS2, which was also mandated by HIPAA. The problem is that EDI is a pain to work with as a data format and hooking up to other trading partners can take weeks of coordination between IT teams (sending "implementation guidelines" back and forth). When EDI is the alternative it's not hard to see how the fax machine survives.

_callcc··on Bitcoin blow as fund drops U.S. exchange application
To get live data from ICE--the exchange that withdrew the request--I'm currently paying a broker $120/month.

By comparison, just about every crypto exchange currently offers push feeds and historical data for free. In most cases you don't even need to sign in.

In some sense this is a measure of the immaturity of crypto markets.

But it's also a reminder that with main institutional players moving in, the barriers to entry will go way up.

We'll probably start to see more brokers and vendors and more consolidation/buyouts of the crypto exchanges.

_callcc··on Snowflake macro photography (2013)
Such a relief to see the word in a headline with its actual meaning.

Plus, the pictures are sublime.

For Hegel this form of Skepticism/Pessimism is one of the "moments" of Spirit.[1]

_callcc··on Death to C, ++
As a younger programmer, speaking honestly, it seems to me a significant part of the motivation behind Rust evangelism has to do with distinguishing yourself against older colleagues who have 20+ years of C systems programming experience. When you find yourself in a field that's supposed to be new and fast-moving, yet you're stuck in a junior position waiting for the old guys to retire, potentially for years, as if you're a journalist or academic or something, it's not hard to see why people look to develop a different skill set.
_callcc··on Recovering from Burnout and Depression
I had really bad sleep issues for years and what finally fixed it was not keeping my phone, laptop, or desktop anywhere near the bedroom. When I was younger I would fall asleep quite naturally no matter what I was doing or where. But now, even if I wasn't on them, having them near to hand would keep me up. They sort of sabotaged that in-between phase, just before you fall asleep.

If the question "How would you turn Twitter around?" is being asked in public with tons of people giving great answers, I'm sorry but you have a major leadership problem.

_callcc··on Trump White House Withholds Cyber-Security Executive Order
Does anyone know what's going on inside the White House in terms of who is working on these drafts and why the first differs so drastically from the second?

We have no reporting on this, only these "leaked" drafts.

The two drafts differ substantially. I don't see how the difference has much to do with the immigration order debacle. That certainly happened in the meanwhile but if anything it seems the second draft has changed to reflect the confirmation of new "agency heads".

The second is noticeably less ambitious too. It's written as if to have little to no effect whatsoever on the status quo.

_callcc··on The Human Toll of Protecting the Internet from the Worst of Humanity
I think we'll see more stratification on the internet in the coming years with subscriptions, etc.

There's probably even a market right now for a paid version of reddit or HN.

The sad fact is that the internet has gradually become a shithole as the entirety of humanity has joined in.

Twitter, for example, is being dragged down by low quality user accounts that add nothing but noise. It's actively hurting the stock price.

_callcc··on Time to Take a Stand
The sort of facts-and-figures type of Democrat doesn't realize that politics is not the same thing as the technocratic administration of society.

Politics is not an optimization problem, it's not about finding the "optimal" state of affairs or whatever.

It's about hopes and dreams. It forms the horizon of the destiny people imagine for themselves, both individually and collectively.

It's also about virtue, morality, sacrifice, etc.

You may sneer but the masses do not.

This is why Democrats lose. They have no vision. What they offer right now is the same boring, stagnant, soul-less status quo, guided along by accurate reasoning about facts and figures.

Why is it acceptable to be so downright anti-political?
_callcc··on Time to Take a Stand
What this is really about for executives like Sam is Trump's meddling in the free movement of labor.

Where the action goes wrong is in its banning of our Kurdish and Iraqi brothers and sisters who have fought alongside US & NATO troops for years now.

_callcc··on Time to Take a Stand
People like Sam Altman are alarmed now that Trump has shown he is willing to meddle in labor markets and potentially impose protectionist labor policies. As Sam says, "This is not just a Muslim ban." Indeed not!

_callcc··on Google Criticizes Impact on Staff of Trump Immigration Order
Management is upset they will no longer be able to use H1Bs to cheapen the value of labor. This executive order won't have a big impact but they see it coming.

The real issue is competition on the world market.

If capital loses a single cent due to this competition they argue for (and win) trade protections and capital controls.

If labor fights against increased competition they're seen as provincial racists who can only compete if they maintain an artificial advantage.

Google should be forced to repatriate its $50 billion in cash held offshore and pay some damn taxes for a change. If they get a tax holiday on $50 billion I should get one for life. Why am I paying nearly 40% of what I earn in taxes while these companies pay nothing?

_callcc··on Ask HN: What is the best Linux distro for a development laptop?
Having spent years on debian, and having run stable and sid, the only really sustainable arrangement is to use stable+backports. Don't run sid! Gradually your system will become a mess and you'll end up doing a reinstall.

If you need a library that isn't in backports, just compile from source and install to /usr/local, it's not hard!

_callcc··on Rust vs C Pitfalls
Go is against the sort of programming that builds up conceptual dream worlds of gratuitous abstraction and needless complexity. When that's the only way you want to think, Go will indeed seem anti-intellectual.
_callcc··on Malcolm Gladwell got us wrong: here’s what got oversimplified
Gladwell is a well-known hack and has a terrible reputation in journalist circles for the shilling he did for tobacco companies while being paid handsomely for it.
_callcc··on Set server timezones to UTC
No, consistency is what matters. If you can get away with working with localtime then there's no reason to opt for the faux-universality of using UTC instead.

`map` and `filter` should take their functional argument first, then data second.
_callcc··on Set server timezones to UTC
Most people in this thread don't seem to have experienced how irritating it is to work in UTC. The argument they make is mainly about logging--they basically want to make sure the log line timestamps are in UTC for the sake of avoiding ambiguity. Fine. But when I want to generate a daily report and all the timestamps in the database are in UTC, it's a pain. Measures of time and weight are necessarily conventional so what really matters is consistency.
_callcc··on Ask HN: What would your ideal programming language look like?
Felt the same about Go syntax. For scripting in C I've had some fun with tcc: "C script supported : just add '#!/usr/local/bin/tcc -run' at the first line of your C source, and execute it directly from the command line."[0]

_callcc··on Mad Map: Python Road
IIRC the change is related to the change in `iter` which in python2 returns `None` after exhausting a list but in python3 will raise `StopIteration`.

Very annoying TBH. I had some really nice list chunking functions using `map` on python2 that no longer work on python3.
