useful··on U.S. government limits exports of artificial intelligence software
imo, working memory at scale via improvements to more obscure methods like a DNC is what will be the next leap and make todays 'AI' seem mundane. Most AI today like deepfakes involve giving the model all memories available via input.
useful··on How a preventable disaster killed six marines
I saw a proposal a long time ago on TEDx or something on how the military should be split between people who fight wars and the people who support wars. The premise was that the supply and support mission should be handled by the department of state in times of peace and the department of war in war. Things like supply ships, bases, hospital ships, aircraft carriers, merchant marine, peace corps, etc all go to providing aid in peacetime and supporting the military in times of war.

Maybe I'm naive, but I always thought it was a nice way of approaching the rest of the world. In reality, the most effective militaries in history have been the ones where everyone can fight.

useful··on A lot of complex “scalable” systems can be done with a simple, single C++ server
PCI-e 4.0 and 5/6 enables consuming absolutely insane amounts of data. I can't think of many applications that need that.

128GB/sec? sure! and 256GB/sec is coming.

With 10Gb, 40Gb and 100Gb internet links becoming mainstream the roadblock to having cool stuff is developers to make it.

useful··on Evolutionary history and why physical activity is important for brain health
Climbing reduces cortisol (stress hormone) by producing testosterone. I also think fear makes you forget about everything but the problem and grounds you in what matters in life (usually not work).

useful··on A Dropbox account gave me stomach ulcers
haha this is the kind of shit that happens when the engineering team cant get anything from the either the sysadmins or leadership.

Can't run an application? Can't afford a license? Use the network share. No network share? Use dropbox.

useful··on Uber and Lyft Suggest the Days of Cheap Rides Could Be Over
I think it is still a race to the bottom while you can get all rideshare prices in google maps.
useful··on S&P 500 Buybacks Now Outpace All R&D Spending in the US
I don't.

If only 20 widgetshares exists in the world and we each have 50% (you have 10 and I have 10) and the market for widgetshares is $200.

Should you be taxed for your theoretical $5.26 gain if I destroy 1 widgetshare but you haven't sold any. Buy backs are no different. You will pay taxes if you sell.

Personally, I think you should pay taxes if you take out a loan using the market value of the shares as collateral. This is where everything starts getting funny and companies and individuals start being able to avoid taxes forever.

No, I assume it was paid by the company paying me.
useful··on Bill.com Files for $100M IPO
As a contractor, I've been paid via Bill.com it was very easy to collect and send money. (not like I had a choice in the platform)
useful··on Intel publishes misleading benchmarks against AMD
people are having trouble going AMD in cloud because their monitoring, while written for x86, is intel specific. All that virtualization software is going to take a few years to be rock solid on AMD.
useful··on I Accidentally Uncovered a Nationwide Scam on Airbnb
Hotels have horrible inventory management. They don't have the revenue management tools that airlines have. I believe there are whole call centers of 1000s of people at expedia who call hotels to verify room availability and rebook customers.

Another example is Marriot will commonly let the local management control inventory. They commonly use the cheapest room to book to max capacity and upgrade people until they are fully booked. It almost never makes sense to book a more expensive room unless you are booking within 30 days.

useful··on Xfinity Is Man-in-the-Middle Attacking My Internet
You don't re-wrap. You just downgrade to HTTP.

This is why TLS1.3 and HSTS exists.

useful··on Xfinity Is Man-in-the-Middle Attacking My Internet
This is related but what is the best trade-off for security vs privacy? Personally, I'd love the ability to inspect what goes over my network and devices. I should be able to choose to intercept/log unencrypted content. (I guess this is actually the NSA-lite argument) With key pinning and HSTS it makes seeing what the content of a packet is really hard. On android you actually have to hack apk's to replace the keys.

It used to be very easy to put everything through a proxy server or mitmproxy and install a certificate on a device. While I value privacy and security it seems like everyone tech company moves to "protect users" is really a way to keep their adware and spyware running on their walled gardens.

useful··on Not even Airbnb can turn a profit
Airbnb has done a good job at defending their platform while uber/lyft has not. The best example of this is how you can compare prices on google maps for ride sharing, flights, and hotels but not for home sharing.

They have no immediate pricing pressure, they control the margins and the advertising. As long as they spend on marketing and avoid creating channels in aggregators they will be ok.

My only worry is that they do 5-10B/year revenue? So maybe they become a 30B company. It already looks like they will IPO above that, which will be unfortunate for any retail investor.

useful··on Companies Use Borrowed Billions to Buy Back Stock, Not to Invest
Most people miss that this is a way to move money without paying taxes. If you pay to onshore profits, you can avoid taxes until another tax holiday by taking out a loan, paying minimal interest, and avoiding having to onshore money for a long time.

ROCm is supported natively in TF 2.0, so they will benefit from that.
useful··on Webvan
cookies are sent with every request, you were lucky to have >28k modem back then. Json didn't really exist, xml was king.

There were plenty of reasons. Apache needed a mod to store a session in a cookie instead of a url and HTTPS was really hard to do. Java had its way, PHP had another, ASP had another... everything was different and there were no patterns.

useful··on Olivia: An open source chatbot build with a neural network in Go
Someone here described chatbots really well. They attempt to address a failure of your product.

The problem I see is that if you want to know what it's doing you could probably spend less time fixing the issues that the chatbot attempts to solve.

useful··on To Message Bus or Not: Distributed Systems Design (2017)
Some of the most complex systems in the world use a message bus. The entire car and air industry come to mind.

Being able to see a message between systems and have an analyst figure out whats wrong and what it needs to be is an awesome way for a developer to actually code.

useful··on Openpilot – open-source self-driving agent
Cool, I'd really like to use this for a small scale toy car. I'd never put it on something that could do more than bruise an ankle.

You can now do an instant ACH transfer of 5000 or less with Chase. Takes about 5 minutes. I do it between Chase and BofA.
useful··on Fastly S-1
I think you underestimate what the edge will become. There are already startups trying to store your data at your house, cellphone tower, isp, etc. In ways where there is no central store or in ways that everything is eventually consistent. Computing at the edge is a very interesting topic.
useful··on Why I Switched from Visual Studio Code to JetBrains WebStorm
In my experience this is the same for people who use a low level text editor as an IDE.

The code that comes out of developers that use IDEs is normalized in a way that makes it very easy to change. Sure, if your big enough you can spend all your time inventing linting rules and creating templates to generate scaffolding and tests.

Can you hide your contact details? The service is super cheap but that spotlight has a hidden cost.
useful··on Wondering about the link between intelligence and meaning
It feels good to learn something at the intro/hobby level. It provides an easy dopamine hit.

In order to become an expert in the population it requires a mastery that is hard. It requires a few orders of magnitude more effort with less and less reward as you become more and more competent.

Collectors of basic intro knowledge could be looking for something they enjoy but there are a large portion of people who do it because it feels good to learn. This is a trap for smarter people and I'm sure everyone knows the career academic with a multitude of academic degrees or a friend with a new hobby every month.

I think everyone should try to be a in the top 1-10% of some pursuit at some point in their lives to see the amount of effort and planning it takes to be at the top of something. You don't have to stay at the top. It makes you appreciate the people at the top of things more because you more easily recognize the effort it takes to be great. Too much of society is focused on the natural ability or luck involved to be at the top. It could be argued that a PHD is this, but I believe that its sort of forced because there are economic and structural motivations that are available that aren't the same as only having a personal motiviation.

useful··on Air Canada agents reveal overselling practices
Airlines are built around operations and scheduling. Some disruption/reaccommodation software is quite advanced and even takes load factor, cost, status, and customer LTV into account. Being able to reorganize entire schedules onto other planes and other airlines in minutes while still maintaining a 1-3% profit margin is non-trivial.
useful··on SoftBank’s next bet: $940M into autonomous delivery startup Nuro
It moves the needle in ways that have not moved much since the advent of fast food and microwave dinners.

- It saves you time.

- It reduces your need for expensive appliances and electric bills.

- It reduces your need for an expensive car.

- It reduces food waste/spoilage.

- It allows cheaper access to delivery for all, especially the disabled/elderly.
