grn··on Germany paying $5.5B for Intel fab
I used to believe that but have started to serious doubt it. Some counter-arguments:

1. It's reasoning a'la "It's economically inefficient therefore it's less likely to happen". In my opinions, governments are absolute experts in implementing economically nonsensical policies, international conflicts included.

2. Any link between nations can be weaponized, i.e. imposing tariffs, banning imports/exports, and so on. The greater your dependency on me the more ways I have to harm you.

3. Such weaponization will naturally harm your own citizens but you, as a decision maker, will bear very little cost.

4. The easier it is for me to replace you with an alternative the more likely I am to use that against you -- this is classic BATNA. You don't like my export quota? So what, I've got more interest than I can handle and you can build your batteries without lithium if you don't like that.

grn··on List of Tech company layoffs in Europe
It's much more convenient if you have a system for doing groceries. Compare visiting 2 stores in walking distance (~ 90 minutes total) vs putting a predefined list into your basket and optionally add or remove a few items (~ 10 minutes).

I didn’t realize there’s a pro version so thank you for posting this. I’m going to give it a try and will pay happily if it improves my workflow.
grn··on Ask HN: At what point do you have 2 pages in your resume?
I’ve prepared a three-page version with the intent of reducing it down to a page or two per application. I ended up using the full version in all applications with project specific highlights in each.

I’ve never had a one-page resume. It was two pages until recently. I’ve played a lot of roles (backend, front end, kernel, system level, infrastructure, product design, leadership, consulting) and a longer resume makes it easier to show that versatility — its my major selling point.

I think what to put there and how to phrase it is MUCH more important than length.

grn··on The Financial Times’ 404 page
I love that kind of attention to detail. It's easy to treat the 404 page as something not needing any thought at all so it's refreshing to see some still care about such seemingly irrelevant details.
grn··on Amazon warehouse employee in Poland dies at work
According to https://kanbantool.com/kanban-guide/water-spider:

> A water spider is a Lean production personnel role centered around timely and accurate stock replenishment. The water spider team member is similar to a mobile Kanban system that refills the production line with the required materials to maintain a steady flow.

grn··on Bypass Paywalls – A Firefox extension to bypass paywalls of many news sites
Correct me if I'm wrong but I think publishers are trying to have the cake and eat it too. They want their content to be discoverable in search engines. They also want readers to pay for it. Given how search engines currently work this is a self-contradictory model.

I imagine search engine could offer publishers an API to send content for indexing without having to publish it. Google and others could even charge publishers for that and then published could ask readers for subscriptions.

grn··on Juno Solves 39-Year Old Mystery of Jupiter Lightning
You got the formula wrong. The surface area of the sphere is 4πr².
grn··on Juno Solves 39-Year Old Mystery of Jupiter Lightning
A given amount of light emitted by the Sun is spread over a sphere of radius r. As the light propagates the radius gets bigger and bigger. The light per area is proportional to 1 / 4πr². If the radius grows 5 times then the area of the sphere grows 25 times.

I was puzzled by the difference in ETR in Q42015 and Q42016 (5% vs 22%). What happened in Q42015 that made the ETR so low?

I’m a full-stack engineer and have some availability in my calendar. Example results companies I worked for got: - Smaller risk of unwarranted automatic payouts (the total payouts volume measured in millions of EURs a year) - Ability to enter another market and implement features customers requested. - QA feedback cycle reduced from weeks to minutes. - Support overhead reduced from 40 to 4 hours a month. - Less unwarranted payouts in an online for-money gaming site. If this sounds like something your company could benefit from please send me an email to contact@gregnavis.com. Also, I’m happy to provide info — feel free to ask here or over email.
grn··on The Free-Time Paradox in America
> The rich were meant to have the most leisure time. The working poor were meant to have the least.

Only in fairy tales. The conclusion in economic textbooks is always the same: if you're rich the opportunity cost of having a day off are _much_ higher so the more you can create in an hour the _less_ likely it is you'll have a day off. That's why CEOs of larger companies have assistants or, in case of mega corps, helicopters or planes.

Practical conclusion: if you're an independent professional schedule a fixed number in a year of weeks for vacations. If you plan for it you'd be less likely to hesitate than when making the decision on a week-by-week basis. (Said a person who had longer vacations about 5 years ago)

grn··on Abstractions and the role of a framework
I'm not sure whether we can draw conclusions about _adoption_ from this chart. A simplistic model could assume that

    adoption = integral of popularity over time
The peak adoption is where popularity is zero. This model doesn't include software that's been decommissioned or migrated to another platform.
grn··on Before I Can Fix This Tractor, We Have to Fix Copyright Law
I'd even say that a license clause that forbids users to modify the software is really not well-defined. Modification of what is actually forbidden? I have no access to the source code (assuming closed-source software). I have only binaries. Can I replace the first byte with 0x00? The second one? What if I accidentally overwrite the whole file with 0x00s? What if I truncate it? Can I start the software and modify it at runtime? Can I modify the dynamic libraries (or even the OS) to alter the software? What if a virus infects the binary?

It'd be great if anyone could point to interesting resources on this issue. It seems to be an intriguing intersection of law and economics.

grn··on Where to hate daylight saving time and where to love it
I'm wondering what the potential for savings is given that only 2.5% of the whole US energy consumption is lighting of commercial and residential buildings. Could anyone estimate the savings?

grn··on Finding bugs in Tarsnap
If I recall correctly the source and destination of strcpy cannot overlap. If they do it's an undefined behaviour.
grn··on The sad state of sysadmin in the age of containers
I'm guilty of using this method in my side project (https://github.com/grn/bash-ctx). My goal was to solve the installation problem quickly. I absolutely would love to offer proper installation methods. However my experience with building *.deb packages makes me think that it's not something that I'd like to do (especially it's a side project).

The question, therefore, is: what is the simplest alternative installation method for OS X and Linux?

grn··on Dell XPS 13 Review
Amazingly, Dell claims 15 hours 12 minutes of battery life, and on our Light test we hit exactly that.

That sounds really impressive. Congratulations!

I have mixed feelings when it comes to Dell. I use Dell U2713HM. Initially I got the first revision which had issues with a buzzing sound emitted when displaying a pattern on the screen. It completely died after a few weeks. I got a replacement (third revision) and haven't experienced any problems since.

I haven't owned a Dell laptop. How good are they when compared to other PC laptops and MacBooks?

grn··on Source code of Polish electoral voting system?
The government messed up the public procurement. They wanted to have the system done in a very short time (one month?). Only one company submitted an offer.
grn··on China Just Blocked Thousands of Websites
I think that, from the economic perspective, it's just a form of protectionism. You help local producers at the expense of consumers. Few benefit at the expense of many.
grn··on The Great Lightbulb Conspiracy
It will be worth more than the competing products (all else being equal), but it won't be worth twice just because it lasts twice as long.

Absolutely agree. You rightfully point out broad simplifications that I made, though I think we agree that there's still an incentive for companies to build better products. Even if the price of the new bulb lower than 2 USD, but above 1 USD, the produces has an incentive to sell it - lower sales costs (you need to do it once), lower warehousing costs, etc. On the other hand the new technology can be more expensive than the old and offset these benefits.

grn··on The Great Lightbulb Conspiracy
If it were possible, say, to create a light bulb that lasted 1,000 years for a dollar. Who could afford to make such a thing?

I sense that you think manufacturers don't have an incentive to produce quality products like bulbs that can be used for a long time. I think you're making a mistake which I'll try to illustrate with an example.

Suppose light bulbs cost 1 USD each and last 1 year. I invent a new light bulb that is the same except it lasts 2 years. Would you say selling it would be a bad deal for me? Of course if I were to sell it for 1 USD then it certainly would be. But the value of my bulb to consumers is at least 2 USD, because it's equivalent to buying and using two competitors' bulbs! Manufacturing costs aren't relevant - if my bulb is cheaper to produce then it's even better for me.

You shouldn't look at the cost of production because it isn't the only factor. Take a look at e-books, for example. Sometimes they're even more expensive than paperbacks!

grn··on The Great Lightbulb Conspiracy
I think that the problem of pollution, and other externalities, can be best handled by Pigovian taxes, not by explicit bans or heavy-handed regulation.
grn··on The Great Lightbulb Conspiracy
When there are two ways to light a room, yielding the same amount of light, but one uses much less energy, it is the superior one.

Not necessarily. What about manufacturing costs? If manufacturing a CFL/LED is more labour or capital intensive then it's production uses resources that could have been used to produce other goods. If that's the case then a ban on incandescent light bulbs has a hidden cost.

You shouldn't look only at the visible effects but also at those invisible. A great essay That Which is Seen, and That Which is Not Seen [1] by Frederic Bastiat comes to my mind. It explores this kind of situations.

grn··on Poll: Are you a drinker or a teetotaler?
I haven't seen the term before too. It's etymology is interesting: 1830s, from total, the reduplicated tee being an intensifier – “T-total” (see https://en.wiktionary.org/wiki/teetotal).
