richev··on Palm Oil Was Supposed to Help Save the Planet
I think that it's the predictions of doom that call attention to the risk, and allow us (or have done so far) to avert the crisis just in time.

True, but leading by example would be a good start.

Personal anecdote: about four years ago, living in London, I needed a plumber to do a small job just before Christmas (replacing a leaking shower tray).

Of the three who came out to quote, we went with the Polish one because he was the most professional in his manner, gave us a written quote on paperwork with a company VAT (tax) number, and gave us confidence that he would do a quality job using quality parts.

This he did, for the amount he quoted.

As for cost? His quote was the most expensive.

Yellow IKEA pencils - in what country? I've only seen unpainted ones (in the UK, and also the US from what I remember, circa 2004-5), with IKEA printed in black on the side.

richev··on Ask HN: Getting to onsites, but consistently failing
A mistake I used to make: not preparing for the onsite interview.

Things like...

* Researching your interviewers beforehand. I start with LinkedIn. It can be useful to know if they have just joined the company, or have been there for years.

* Making sure you have some good stories to tell about your most recent role, what things _you_ did/influenced/changed. Practicing them with a friend or spouse.

* Being physically prepared for the interview, getting a good night's sleep beforehand, arriving at the office in plenty of time so you're not flustered. I aim for >30 minutes early. Don't actually go into the office until 5-10 minutes before the interview is scheduled to start though.

* Finding out about the dress code at the company, and dressing accordingly or, if in doubt, slightly (but not too much!) smarter than the dress code you expect.

* Being ready to give a good handshake - warm, dry, and politely firm. If you notice your hand is cold and clammy beforehand, sit on it for a bit!

* Making sure you are polite and courteous to everyone you meet in the office. Maintain your posture. If you normally chew gum, don't. Assume that the interview starts the moment you set food inside the building.

* Be ready to appear fascinated and interested in the job role. Have some smart questions to ask at the end when they say "any questions?"

richev··on Ask HN: What are some of the best documentaries you've seen?
If you have any interest in the Apollo missions...

In the Shadow of the Moon [0]

The film follows the manned missions to the Moon made by the United States in the late 1960s and early 1970s. The documentary reviews both the footage and media available to the public at the time of the missions, as well as NASA films and materials which had not been opened in over 30 years.

For All Mankind [1]

A 1989 documentary film drawn from original footage of NASA's Apollo program which successfully landed the first humans on the Moon from 1969 to 1972.

Moon Machines [2]

The miniseries features interviews with around 70 of the 400,000 engineers who worked on the Apollo program during the 1960s and early 70s.

These are variously available on DVD and YouTube.

For back pain, the first step I'd recommend is to see a physiotherapist and get their opinion on your situation.
richev··on Show HN: Let’s Encrypt SSL Certificates with Azure Cloud Service
I agree, the approach had loads of limitations, as you've identified.

1. Yep, this is my scenario, so the steps are written for this.

2. When my certificate expires in about 2.5 months I'll pick this up again, and will be trying to work on automating more of the steps. Suggestions welcome!

richev··on SpaceX is working on a kid-size submarine to extract those boys in Thailand
Full face diving masks are designed to have an air flow that helps minimize CO2 buildup[0]. The greater concern is that they might leak due to not fitting properly, and/or the user might panic and pull the mask off while underwater.

With a flexible pod, you'd partially deflate it to get it through awkward areas, which would make it negatively buoyant. Once re-inflated to the previous pressure it would be neutrally buoyant once again.

Re-inflation could be done via the same gas cylinder that's being used to replenish the air in the pod.

richev··on SpaceX is working on a kid-size submarine to extract those boys in Thailand
Of the difficulties the pod solution poses, I don't think that neutral buoyancy us one of them, so long as the pod is rigid (e.g. steel) in construction.

The best succinct definition for neutral buoyancy I could find was this one, from Wikipedia:

> ...a condition in which a physical body's average density is equal to the density of the fluid in which it is immersed.[0]

This means that once the pod has been weighted to be neutrally buoyant it will be so at any depth of water, since neither it or water are compressible[1] and thus their average densities are unchanged by depth.

The challenges of maintaining neutral buoyancy arise when you submerge a compressible object, such as a scuba diver wearing an inflatable buoyancy control device (BCD). The water pressure (caused by the weight of the water above) will squeeze them and their equipment, compressing anything that is air filled.

To sink from the surface, the diver has to deflate their BCD, and then put sufficient air in it to achieve neutral buoyancy at their desired depth. If they swim downwards, the higher water pressure will squeeze them some more, the air in their BCD will compress some more, and their average density will increase. They will now be negatively buoyant and will sink.

The deeper they sink, the higher the water pressure will be, the more the air in their BCD will compress and the more negatively buoyant they will become. So they'll sink faster and faster. This happened to me once when I was first learning to scuba dive. It can be scary.

The opposite applies to ascending. This is why good buoyancy control is such an important (and difficult) thing for scuba divers to learn.[2]

From a buoyancy perspective, a metal pod is more like a camera in an underwater housing. These are rigid in construction (usually either plastic or metal) and their buoyancy characteristics don't change with depth.

Summary: get checked-up every now & then, or if you experience any sudden change in your health.

richev··on The rise of the pointless job
I saw a similar thing at a Mars chocolate factory in the 1990s: a lone worker with a conveyor belt of chocolate bars to one side, and a robot opening up boxes to the other. The worker was grabbing handfuls of chocolate bars and filling up the box that had been presented to him. When full, the box would head of down another conveyor belt and be automatically stacked on a palette ready for shipping.

Long-since automated I suspect, but at that point in time I presume that the human was cheaper and more reliable than the equivalent robot.

Aside: the equivalent job on the M&Ms production line _was_ being done by a robot, and required the packets of M&Ms to be neatly lined up in their boxes.

I've seen this at airports that had seemingly small or poor quality luggage belts, and figured that their actual role was to help ensure the smooth running of things and stop the belt jamming up with too many bags.

The use of "chrome" in this context isn't limited only to browsers[0].

My recollection is that Google Chrome was so-named because one of their design goals was to _minimize_ the amount of GUI chrome, so that the maximum amount of screen space was available for displaying web page content.
