I reached the same conclusion for my own static blog. One step beyond just having an email link is to run an AWS lambda that takes a web form post and sends you an email with the contents. That way you can add a captcha (hCaptcha seems like a good alternative to Google), and your email address doesn't float around on the public internet. It's fairly low maintenance and easy to replace if you ever did want to step away from AWS.

I've been playing around with the Lego and Raspberry pi combination on and off through the years [1], with the goal of building a standalone tracked vehicle (pi on board) that can move around my apartment. There were various ways to do this already, mainly by using off the shelf motor controller boards and later the third party Bluetooth motor bricks. This was all for the old "power functions" system though, Lego has since revamped their lineup with a lot of new parts that all use a different connector. I'm really looking forward to getting one of these.

I love cycling. Did my first solo touring cycling trip over ten years ago when I was in my twenties. I've done a cycling trip every couple of years since then, until I got a mortgage. Then I started focusing on my career and kept delaying the next trip, thinking "next year will be the year that I'll make time for it". Now I'm approaching my 40s, I have a medical condition that limits the enjoyment I get out of cycling, and due to covid travel restrictions I can't travel to the country I want to cycle in.

Don't delay.

Wow, this is a lot more in-depth than I was expecting. I started out with the O'Reilly book (Hands-on Machine Learning)[1]. There's some overlap there, but I'd say both this course and the O'Reilly book are well worth your time if you're starting out with machine learning. [1] https://amzn.to/2kKaNiQ

I had never heard of Krypton before, but the decisions and the message in that article make it abundantly clear that I won't need to bother. Moving from golang to C and switching to a completely different blockchain in 'a single sleepless night', and then asking the community to bail you out? Zero confidence.

You're right about the parking bit but I have a hard time believing you about the rent or the building quality. I lived in Kanagawa for 5 years in a very old (for Japanese standards) apartment building, and it was rock solid. Don't forget that these buildings are designed to withstand earthquakes, whereas London buildings are just slowly rotting away. Regarding rent: http://www.numbeo.com/cost-of-living/compare_cities.jsp?coun...

Nowadays I'm living in London and have seen housing for way higher prices and way, way worse condition than the apartments I've seen in Tokyo. London build quality is utterly terrible. Japanese build quality is quality.

But if everything that could possibly reference a class or tag or attribute is inlined into the same file then you know exactly what the scope of your CSS is for that particular request. So it should be possible to minify even the names.

You could argue that finding out hidden possible requirements in a high-stress situation is also part of a developer's job.

This was utterly fascinating. Is there a Japanese version of this? I would love to rub it in some people's faces.

The article assumes that if 1000 positive gene changes are responsible for increasing intelligence, you'll get 1000 increases of intelligence. It's much, much more likely that a lot of those gene changes overlap, meaning combined changes won't affect the IQ any more than either/or changes would.

Programming can be art, but only extremely rarely is work programming also art programming. Even when you have the best of tools at your disposal, even when you're working with the best people and the most reasonable clients, you're still solving business requirements, not freeflowing into a design that just jumped into your mind a few seconds ago in a flash of inspiration. Solving business requirements should not, cannot be art. It should be robust and maintainable and boring. If you keep art programming and business programming separate then you'll inevitably find that one or the other does not agree with you.

What you are describing is optimal task scheduling. Procrastination is what you do with the time that you're not spending on your task.

Oculus Connect 2014 12 years ago

Integrated audio is going to be a dealbreaker for me. If I can't use my own high-quality headphones I will not use an Oculus.

It's partly, or even mostly, a problem of trust. Back in the wild days of the internet you just couldn't trust a website to have a lot of control over your computer. You could argue that this is no longer the case since we're slowly building up the 'web of trust', but I think we're not quite there yet. Since there used to be less facilities to write speedy online software (secure offline storage, closer-to-the-metal 3D APIs) people were stuck with the old HTML+Javascript and never really evolved out of it. It's not the right way to go, but it's a necessary step to develop the infrastructure that'll be necessary for the next big leap.

How to Be Polite 12 years ago

Excellent article, and I feel it also applies to me, so I wrote down some thoughts. maqr's comment about this being dangerously close to social engineering rings very true, although I doubt that it's intentional/by choice. Personally I've never had a lot of natural conversational skills, so I find myself falling back to old tricks that work at times when I'm not confident, and sometimes they happen to be tricks that relate to social engineering. I'd like to think that this doesn't make my interactions less genuine. Finding a polite way to proceed through the conversation has not been a problem for me since I learned this.

Lately, rather than moving towards politeness, I'm trying to move away from it. The examples of always replying positively to people, never steering towards or even approach hostility is a very, very tiring path to walk. In my experience, it does pay off on the whole, but I've spent a lot of time talking to people that were just never 'interesting' or 'rewarding' to be with, simply because it always seems easier to please than to confront.

These days I'm trying to move towards blunt honesty with people as soon as I can (after an initial period of polite conversation to gauge if they'd be comfortable with it). So far, I think the people I know appreciate me more for it, and the people who wouldn't appreciate me for it are not in my life.

Or perhaps it just feels good to try something different.

No actually, I meant the MtGox source code that deals with transactions. The malleability issue was known long before MtGox announced the exploit. It's possible that MtGox initially handled transactions correctly, but later introduced the malleability issue so they can blame their problems on that. Like I said before, I don't believe that's the case though.

Assuming that MtGox (let's say MtGox, not Mark) did indeed introduce transaction malleability as a feature, that should be very easy to prove with source control commit logs. But if the malleability vulnerability was already there to begin with, it would be very hard to prove indeed that MtGox was taking advantage of it.

Edit: I should also add that Mark in particular has not proven himself smart enough in my eyes to pull something like this off. In terms of technical skill, yes, but this requires a very human approach to deception which I, based on the conversations I've seen him have, do not think he possesses.

To up the conspiracy theories a bit, do you think it's at all possible that someone skilled in programming and cryptography, well-versed in English and with a priority for keeping his identity secret, just might attempt to obfuscate his language by altering his writing style? If you don't think that's entirely unlikely then you'd better adjust your p-value.
