safog··on Tech can't remember what to do in a down market
There's several issues here though:

1. For most people symptoms are so minor that they don't go to the hospital at all and don't get counted in the reporting stats. This means that the 18% number is higher than reality. How much higher we don't know.

2. The disease disproportionately affects older people: If you're between 0-50 your chances of dying are ~0.2%. From what I can tell these mortality odds are better than if you have the regular flu.

safog··on U.S. immigration policy has been a boon for the tech industry in Canada
How did you infer that from the post?

Doesn't matter even if they did because GC wait times for Indians are ~50+ years right now.
safog··on IBM Names Arvind Krishna CEO
The language / the cultural barrier isn't as high as it is for an American living in China though. I've grown up speaking English and watching a lot of American / British movies and TV, reading a lot of english literature. I assume this is not the case for most Americans with Chinese culture.

There's definitely a culture shock when you first move here and are figuring stuff out - How do you order food at a subway or a chipotle? (not a big deal anymore given the explosion of these restaurants in India in the last few years). Why is called Cilantro and not Corinander? How do I get a phone when I don't have any credit history at all? What is a turn-pike?

safog··on Autistic futures trader who triggered flash crash spared prison
The autism bit aside, it looks like why they got him in the first place was that a technique he used (spoofing) was illegal in the US.

Given he lives in England why was he extradited to the US? Is the summary that US has enough political power to have anyone who breaks US law wherever they are situated extradited and tried here?

safog··on Leaked documents expose Avast antivirus subsidiary selling web browsing data
I think there's several different underlying causes to Windows feeling more secure (not needing antivirus) these days:

1. Security on desktops has been improved quite a bit. You can no longer simply email someone a .exe file that's the equivalent of `sudo rm -rf /` and have it work, multiple levels of safeguards (from the browser, to the email virus scan to windows defender catch it). OS's also simply won't run unsigned binaries anymore unless you force them to which is (maybe?) a good thing.

2. Piracy has been on a downtick, and people seem to be more open to paying for software since App stores made it somewhat more acceptable. Less likelihood that people download sketchy binaries off the internet and run them on their PCs.

3. More hours spent on mobile OSes which are inherently more secure. casual PC usage at home is declining.

safog··on Finland’s Prime Minister Calls for Debate on 4-Day Work Week
It's surprising to see so many on HN agree with a 4 work week. As a programmer, I will definitely get more done in a 5 day week than in a 4 day week.

I assume manufacturing jobs will need to be 5 days or America will be even less competitive and the same for service jobs, gigs.

I wonder what jobs will actually benefit from a four day work week.

safog··on Ask HN: A New Decade. Any Predictions?
I think these predictions are way too safe, to the point that they aren't predictions at all. These are all very widely accepted views already (in the tech community / HN atleast) which explains why this comment is top currently.
safog··on Where Are the Tech Zillionaires? San Francisco Faces the IPO Fizzle
Who are all these tech workers who want private parties and yachts and pent houses and sommeliers in their apartment?

Everyone I've worked with up to director levels at FAANG are mostly content with just investing their riches and maybe thinking about retirement or sending their kids to private schools. I haven't seen any extravagant displays of wealth - some BMWs / Teslas in the garage but never a Ferrari for instance.

safog··on Rob Pike on good commit messages (2014)
I feel you here, but it's up to tech leads / Sr. Engineers to push back on management bullshit like this because otherwise the commit messages aren't the only thing in that culture that'll make an engineer miserable.

My management horror story here is having a SCM (source code manager) who was responsible for taking code checked into a VCS and deploying it to prod (using a CI system no less). He used to insist on engineers sending him a word document with a very specific template on what files changed, what binaries need to be re-deployed etc. etc. for every single commit or it wouldn't get deployed at all and his day was made up of yelling at engineers because the template was incorrectly formatted, or used the wrong font or whatever.

Noone else could touch prod (or even staging) except him and all of this process originated from an engineer messing up a deployment and bringing down prod.

My takeaway from this entire experience was tech middle management at smaller, enterprise-y shops was just completely broken and all these guys were capable of was playing silly political games. If possible, just work with smart people, if you can't evaluate if someone's smart during an interview process, just work for one of the big tech-cos and you can't go wrong.

safog··on The Great Cannon has been deployed again
The real question is if anyone would've even cared about the atrocities of Nazi Germany if it wasn't in their national interest to go to war.

The reason England and France got into the war is because of Germany's expansionist policies and not because of moral reasons at the time.

safog··on AMD’s Entire Ryzen 9 3950X 16 Core CPU Inventory Sold Out in Japan
What's the latest on VM tech? Is it still using Virtualbox + spinning up multiple VMs?
safog··on AMD’s Entire Ryzen 9 3950X 16 Core CPU Inventory Sold Out in Japan
Haha, I think it can be tastefully done. Of course, the PC shouldn't look like a Unicorn puking rainbows, but I'm a fan of having a glass panel that shows off components with some subtle single / dual color lighting.

So yeah, I made some questionable technical decisions purely for aesthetics but yeah form is kind of important too.

safog··on AMD’s Entire Ryzen 9 3950X 16 Core CPU Inventory Sold Out in Japan
I bit the bullet and upgraded from 4670k + DDR3 --> X570 Mobo + R5 3700X. Costs ~$500 assuming you can keep your GPU, PSU, Case, fans etc. and you don't want to go all our RGB on everything.
safog··on Uber loses licence to operate in London, will still operate while appealing
I'm honestly pretty cynical about EU laws these days. All they're designed to do is to whack around American tech companies until they cough up $X bn for their coffers.

Not that America is any better these days, NJ recently decided to get into the game and started to go after Uber.

Inspirato keeps spamming me on Instagram with this exact ad. $2500 / mo, any of their hotels across the world. No idea if this is some glorified time-share.
safog··on Uber Sinks to New Record Low as IPO Share Lockup Expires
They claim they'll be profitable by 2021.

safog··on Uber Sinks to New Record Low as IPO Share Lockup Expires
From Q3 results, it sounded like the company was profitable just on ride-sharing itself and was losing a ton of money on eats + cargo + autonomous vehicles R&D.

I wonder what a fair valuation would be for just the ride-sharing business if they were to spin off / shut down every other part of their business and essentially become Lyft.

safog··on One Tether Trader Didn't Cause the Bitcoin Bubble
Yes, some of it was organic, but towards the end of the bubble, folks were looking at tether printing and using that as a signal to buy / sell. People even during the bull run called out tether for being the biggest risk to crypto markets and understood that without this well-timed injection of cash into the crypto markets, the price would fall flat.

Given Crypto markets' propensity to scam, I'd be shocked if finex & co didn't engage in manipulation. Maybe not to the extent that the paper's authors claim - China, S. Korea, India all banned / tried to ban crypto and I think Chinese volume drying up was a major cause for the bubble popping.

safog··on Ask HN: What's a promising area to work on?
Re: upscaling, I was reading another article on HN about a specific species of plant when grown in sufficiently large quantities (6x size of Texas I think) would basically bring us down to carbon neutral. We can probably scrounge up that land if the world works together but who knows.

Re: engineering biosystems, I imagine engineering native plants (if possible) has much fewer ecosystem wide chain effects) than using gene drives to eliminate mosquitoes or whatever.

Re: crispr, I see photos of glow in the dark monkeys and super muscular dogs, so as a layman it seems like cutting a gene and vaguely throwing the desired gene near the cut location seems to work. We don’t have as many ethical implications about rapidly iterating on plants as we do on animals, so it seems like if an experiment doesn’t work, just repeat 1000x until it works would do it. People talk about off-target effects etc. but you won’t really know unless you try I guess.

safog··on Ask HN: What's a promising area to work on?
Yup I agree with you almost entirely. The only thing I was thinking of was if evolution would optimize for the amount of energy a plant receives vs other things like survival, reproduction etc and how much efficiency we can gain by optimizing purely for photosynthesis.

Also I don’t know if plants are adapted to the high CO2 atmosphere yet so even if evolution optimized the ability of a plant to photosynthesize, given this happened in relatively low CO2 environments like forests and without man made climate change, it’s possible that human intervention can improve it.

safog··on Ask HN: What's a promising area to work on?
One thing I've never been able to figure out is that given Crispr, why it wouldn't be possible to engineer an organism that can suck much more CO2 out of the air than any existing tree / algae could. Even more ideal if we can make a good building material out of the engineered plant to sequester Carbon.

It's easy to see how the manual selection process would work here - plant a bunch of trees, see how much O2 each produces and pick Top N and repeat. Of course, this needs thousands of years to run manually because the improvement with each generation would be minimal.

Is the issue that we don't know what gene(s) control photo-synthesis?

safog··on Bank of America's CEO says it's saved $2B per year by building its own cloud
So one thing people seem to be ignoring is that cloud != automated provisioning of VMs by engineers.

There’s so much more AWS, GCP and Azure offer these days that trading away all the stuff like metrics, monitoring, dynamo-dB, s3, lambda, scalable RDS, Spark pipelines and generally a whole suite of products that go into building a modern web app for some scripts that can provision on demand seems to be a poor choice.

safog··on iPhone 11 Pro Camera Review
It seems very unlikely that they are unedited. Any link to that claim? I just re skimmed the article and didn’t find anything along those lines.

For example I would guess this pic has some photoshop to emphasize the light and atleast some simple Lightroom.

safog··on iPhone 11 Pro Camera Review
So I want to throw out something quickly - just because someone claims a photo has been shot on an iPhone doesn't mean that they shot it in the same way as you or I would. Lots of people have special lenses that they attach in front of the iPhone camera lens to get a macro / wide angle view. They almost always shoot RAW with an app that supports this. They also use a mini tripod to stabilize the photo and use techniques like long exposure.

https://pbs.twimg.com/media/EEH38ZxUYAQDPBT?format=jpg&name=...

There's also a lot of editing skill that goes into this - a photographer won't simply take whatever processing the phone comes up with use it out of the box.

I personally use the lightroom mobile camera to capture RAW photos and play around a bit with curves, exposure, hsl etc. to get the look I want. I assume if they're a pro photographer, they move the RAW photo to the PC / iPad and add some photoshop magic as well.

The output (depends on the photographer ofcourse but for the ones I like) looks very natural and doesn't have the same look as simply applying an instagram filter on top of an iPhone camera shot image.

Obviously the composition etc., that folks are talking about matter a lot as well but IMO, these days camera hardware is so good that you can get all sorts of detail out of what you assumed was a blown out camera RAW. Crops work fairly well too because of how high-res the photos are, so if you're not too pleased with your initial composition, crop + photoshop fixes will get you a long way. As a whole, photography these days is about 70% editing and 30% photo taking technique (lighting, composition, aperture, shutter speed, iso etc.)

safog··on Commercial Solar
I was trying to run a similar arbitrage operation when the Tesla powerwall was first released but the breakeven was ridiculously long. Mine was to charge the powerwall when electricity was cheap on the grid and sell during peak. I found that a lot of the grids don't really support this kind of arbitrage at all and with the ones that do, the profit margin is so thin that it's basically not worth it.

As you say, Tesla is reframing the argument from renting your roof --> you selling clean electricity to the grid to make it more palatable but I don't see a problem with that.

safog··on Uber proposes policy that would pay drivers a minimum wage of $21 per hour
You can put a price on those things.

Insurance: 2400 / yr (guesstimate, maybe lower) Miles driven per year: 50k [1] Cost per mile (Incl depreciation) = 0.26$ [2] Cost per year to drive = 0.26 * 52k = 13520 Total = ~$16k per year in post tax earnings.

(Assuming numbers above still work ) Min 21$ / hr = 43,680 Minus taxes = 40,175 Minus driving costs = 24175

post-tax income per month ~= $2k

Assuming a single driver lives outside the immediate SF area, "commutes" to work, and shares an apartment, it's enough to survive. There's plenty of other jobs that pay less, so it seems unfair to target Uber on this number. You can expect to get by temporarily or make a bit of extra cash with Uber, but it's not a long term career for a driver - but I expect most drivers know that already.

safog··on Show HN: IAvisa – Explore visa requirements worldwide
There's a bunch of special cases along these lines - As an Indian citizen, I'd normally need a visa to visit Mexico / Costa Rica but I live in the US on a work visa which means that the visa requirement is waived.

This is just one citizenship, country pair and I assume there's a lot more.

safog··on Empress trees absorb about 103 tons of carbon a year per acre
That's like 6x the size of Texas. Can probably pull that off if everyone in the world pitches in.

Not sure what other effects like invasiveness of the species factor in.
