As long as you are loading with a resonant load then yes, it can work. But as soon as you are in any way reflecting power back on the line or have an impedance mismatch (which will result in reflected power) you're in big trouble.

Another problem is if you use one to switch from say an antenna to a dummy load, you might find that you are leaking quite a bit of power onto the supposedly disconnected antenna link. RF is tricky, especially at higher power levels.

One trick you can use is to use only single contact relays and to bend open the contacts as far as they will go as long as they reliably close again when the relay is energized.

That way you minimize capacitive coupling between the contacts. DC relays are your best bet for a starting point because they already have larger gaps than most AC relays (to inhibit arcing).
You could put the site itself on an external drive via USB - and ideally most of it the access be read-only for a static site, so the life of the sdcard shouldn't be as big of a concern.

That said I'd agree, Raspberry Pi's a great but not quite fast enough for serving a high-traffic website.
Leaving aside the politics and economics, what do you think a better feedback mechanism might look like?
The Implications of RethinkDB and Parse Shutdowns
One of my favorite discoveries, thanks to a suggestion a teacher made, was how inverting a pattern can help you learn something really difficult.

I was learning Beethoven's Appassionata sonata and there's a section where the right hand has a series of five-note arpeggios that gradually decrease in register until the left hand takes over and continues down into the bass (while the right hand takes a climbing melody that originally started in the left).

Those five-note arpeggios were really hard in the left hand. So the technique my teacher recommended was to basically play an inversion of the left hand pattern at the same time as the left hand was playing. So when the left hand started on a Db, the right hand started on an Eb an octave up, and then basically play a mirror version - mirrored by the physical key, so E vs C, Bb vs F#, etc.

It sounded like crap, but it was very effective - since the right hand is stronger, the left hand would basically learn from the right. Pretty quickly, my left hand got very strong at that pattern and it became one of my favorite sections of the movement.
For one thing it is a bad idea for a hiring manager to advertise that the company wants a new grad because it can be perceived as age discrimination; they could get sued. What they can say is that the position is "entry level".

Startups often like to hire young people for various reasons but in a company that has 2 or 3 employees, everyone has to carry their own weight -- they usually cannot give you a lot of on the job training.

One trends I have seen is companies who hire young people to make cold calls; often these people have a PMA and some sales skills, but they don't understand the offerings they are selling well and don't have a complete set of sales skills.

An established company with name recognition and a well-worn playbook can get away with that, but I see many small (<25 employees) companies that struggle because there are two kinds of people you can talk to: (1) busy people and (2) people who will talk all day and never buy anything. Since you get one chance to make a first impression, an initial contact with a poor salesperson can be a very bad thing.

Don't ask "do you hire new grads?" because the real question is "will you hire me?" which can have a different answer if you communicate that you can bring something special.
You either have a hardware problem (mechanical disk?) or a problem with some preinstalled software running in the background.

8GB with even a several years old CPU should be perfectly usable. SSD is absolutely required though. No number of cores and gigs will compensate for the lack of ssd.
Ask HN: Father Is a 61/yo Dev and Just Got Laid Off. Advice?
Just had a very dishearting conversation with my pops about his career situation. He's been programming since he before it was cool (he's got wary stories that involve punch cards) and he was "the guy" I always turned to for advice when I was stuck.

Today the roles have flipped and he's asking me what I'd suggest he do to be "competitive" in the job market.

The only problem is I run a startup and don't have any corporate experience... so I'm at a loss on what advice to give him.

Any insights from some more "seasoned" devs about how to get traction in the job market despite his age?

(His most recent roles as a senior developer on mission-critical Java and PHP applications.)
The uncertainty of investigation pales to the uncertainty of funding.

Su seems almost blind to the fact that you can do math outside an academic environment. You don't need to go to school for math to experience truth, beauty, play, etc in the context of math. You can read books, play around with the results, read articles on places like Quanta. You probably won't discover new things this way, but it will enrich your life.

If your goal is for math to make people's lives better, then assuming school is involved at all is another unnecessary restriction.
Microsoft has successfully trained me that OS upgrades can be very traumatic. I consider myself an early adopter, and I always run cutting edge on my phone or win laptop, but I only ever upgrade my primary workstation when it dies and I have to.

Maybe in place upgrades are fine now, but I haven't trusted anything but a fresh install for as long as Windows has existed.

I agree. I think that mathematics is being teached the wrong way. Especially in the USA, the state of math education is absolutely terrible.

I suspect a more visual approach to be more useful than the classical textbook approach. It is true that a lot of textbooks do use pictures, but video's would help a lot, I think.

I use RankScience for 7 Cups and Edvance360 and I've seen a huge ROI. They always find time to meet with me and my other team members. The advice and feedback they provide is worth the cost of the service alone. Highly, highly, highly recommended!
Do you have a source I could read? This is super interesting.

Sounds like GitHub foots the bill.
I know someone who optimized searching the leaked Adobe database (of a few hundred gigabytes if I remember correctly) on a Pi to a sub-second search. That was super impressive and the method used wasn't even obscure (binary search). The same doesn't apply here, but I'm trying to say a Pi isn't entirely worthless.

For example, what pages get accessed the most anyway? I'm guessing the latest source code and maybe the latest release, though most people probably just apt-get git instead so it's probably mostly the source code. Then there are man pages and some other info pages, if I remember correctly. Sounds like the latest release + 90% of those text pages can easily fit in RAM. So memcached? Nah, the Linux kernel happily caches the files that you read from disk.

I don't know the actual numbers but it doesn't sound infeasible to me. A $230 hosting bill is very heavy though, I guess you'd need some serious fiber as well to provide the uplink. But again, without numbers it's all "maybe" and "probably".
Ask HN: Small, economical office gifts

> I'd much rather have a nice UI to deal with settings than have to figure out that, say, in order to show line numbers I have to modify "editor.lineNumbers" and set it to "on" (or is it "true"? or 1? I can't remember... let me go waste more time looking it up...)

Maybe you've taken a look at it a while ago. It's still a big json file (great! everything at hand) but very easy to edit since it provides a lot of assistance: there's icons to set a new option, references for everything, and intellisense/autocompletion for the schema of every option you want to change. It'll even show invalid options with a squiggle (e.g. when some setting becomes deprecated).

IMO it's the best way to have settings in an app, especially when you can install extensions that adds settings of their own or when you want settings to be version-controllable.
..if you're on an Enterprise SKU. Maybe.
Probably the best/cheapest solution is:

A) Get a Linode VM, put elastic search on it and have it load the text. Probably $20/month with that little text, tops.

B) Use something like KeyCDN to cache everything for long periods of time.

I doubt it'll cost $50/month.
Theoretically the best way to maximize an edge is to just wager larger amounts at all times. This has a beneficial side effect of deviating from 'standard' human play which can be further exploited, although I doubt this the intention of the AI.
Boston Dynamics New Wheeled Robot Called Handle
Su opened his talk with the story of Christopher, an inmate serving a long sentence for armed robbery who had begun to teach himself math from textbooks he had ordered. After seven years in prison, during which he studied algebra, trigonometry, geometry and calculus, he wrote to Su asking for advice on how to continue his work. After Su told this story, he asked the packed ballroom at the Marriott Marquis, his voice breaking: “When you think of who does mathematics, do you think of Christopher?”

It doesn't sound like he has that bias to me. He opens his talk speaking about someone who is a non-traditional student doing match outside an academic environment.
Just because he isn't using the new features, doesn't mean they aren't useful. WSL is great - still needs work but on the insider previews it's on 16.04 LTS and they're slowly knocking out the nagging little issues with it. If you've got a 2-in-1 like a surface book, the switching from desktop to tablet mode is awesome.

If you aren't paranoid (and completely understand why some people are) about the security possibilities, cortana is actually pretty nice too. And as they slowly tie it into xbox and their other platforms it will just become that much more useful. Virtual desktop support is finally there.

I mean, outside of that, what were you expecting from Windows? It's the most widely used desktop on the planet... it's not like there were any major feature gaps that were just deal breakers.

In vintage radio repair, they sometimes will replace old caps (usually electrolytics) with new ones, but put the new ones inside the old cans - to preserve the look of the device.

Obviously, though, this won't work with all parts...
Well, MIDI data itself is still in heavy use in music production, both to interconnect hardware, and within software itself. It's the standard way to represent notes, timing, events, etc. within music-making software (DAWs).

Actual MIDI files themselves? Mostly just used as a file format to share musical/rhythmic motifs or export between music apps, not as an end product in itself.
It probably wouldn't sound terribly great; the site doesn't make any attempt to make sure that the flipped version is in the same key as the original (and in fact that would be extremely difficult, if not impossible), so you'd get a rather dissonant-sounding MIDI.

I was curious though, so I tried it out on the Für Elise example. Here's the unedited version: http://automidiflip.com/merge-experiment/furelise-merged.mid

As expected, it's rather horrible. I tried editing it so that they began on the same note but an octave down (as with Andrew's original video), but it wasn't much better: http://automidiflip.com/merge-experiment/furelise-merged-shi....
I think this is hardly surprising. It seems many Nobel Prize level discoveries, are for significant shifts in the understanding of a topic or field.

I was thinking the same thing after reviewing the repo and output HTML but I wonder if that would really lower the monthly hosting costs for the Heroku instance and the various addons. It would be simple to modify the RoR app to output the proper caching headers that would allow any CDN to cache the HTML output and obey the various cache limits, but on demand rendering the output from time to time is still required once the cache expires.

I think moving the site to a normal static site generator (like Jekyll) would deliver the most bang for the buck but would be quite the transition. The site would only need to be built upon a new commit and with the proper site generator it will only update the underlying HTML files that require a change. Then syncing the update HTML to whatever CDN is chosen.
You woudln't. This would be for an intial obfuscation pass. You'd not do this for release but for sufficiently scrambling the code base.
Sometimes one has to pay that price. Can you suggest an alternative that reduces complexity?
I graduated with a CS degree in 2004 from Carnegie Mellon University and Google didn't give a shit about me until 2011 where they told me they would only hire me if I were working for another local company first. The other local companies didn't want to hire me, because they thought I would just go work for Google. Never met anyone at Google who cared that I was a good programmer or had devoted my life to it. They seemed focused on stealing workers from their competitors. If they want to hire computer scientists, then tell their employees to focus on that in the hiring process. If they have someone with a Computer Science degree who is a great programmer who wants to work with them, maybe they should find the time to speak with them or to explain how they could get a job in computer science or programming.

My experience is that Google things a Computer Science degree is worthless. It can't get your foot in the door to speak to them, you have to be a race or gender they are looking for.

On the one hand, academia has become rather harsh and intimidating and there is room for all kinds of improvement.

On the other hand... there is no world where whoever just wants to study math can just go study whatever they want for as long as they want, regardless of how well they do it. Of course, when I spell it out, that probably seems obvious, but I suspect this may be the unexamined assumption in a lot of people's heads.

So, it's not dead, but it's a very crowded space, and discovery is a challenge. It's the classic red ocean. If you're going to build something, I'd spend the time elsewhere.
