Stryd, Boulder, CO, Techstars Boulder 2015 | Intern | web Developer
http://www.stryd.com

Stryd is a talented, multidisciplinary team that is enthusiastic about creating the future of wearable technology for runners. By using Stryd, runners can train effectively, race strategically, and unleash their full potential. We just released a new product that detects the air resistance the runner needs to overcome during the running in real time.

We are looking for web developers who are knowledgable with mordern web development. Our main tech stack for web includes ReactJS and Vue.js.

Good sense of design is bonus.

Being able to relocate to Boulder for the internship is required. BTW, if you like running, Boulder is pretty much your dream place. You get tons of opportunities to run and train with LOTS of elite athletes who are Stryd ambassadors here. We welcome people of different backgrounds, experiences, abilities, and perspectives. Our work environment is open, supportive, and fast-paced. There is tremendous room for growth.

If interested, please send an email to kun@stryd.com.

Sorry to be pedantic, but no, those people were called "Martians". (His term, "homo ares", is referring to Ares, the god also known as Mars.)

The Belters lived in the Asteroid Belt, and were opposed to both the Terrans and the Martians. The Belters were the most different biologically because the gravity is so low, whereas the Martians got to enjoy the relatively high 1/3 g gravity of Mars.

https://en.wikipedia.org/wiki/Links_(web_browser)

Note I do not recommend using a text-only browser interactively for any sort of commercial or important online activity. I use it for recreational activities like reading HN and the websites posted here.

I used lynx many years ago in the early 90's. After switching to links, I would never intentionally use lynx again. It amazes me that people still mention lynx when the topic of text-only browsers comes up. I would be shocked if these people who recommend it are using it as their browser on a daily basis for decades.
I've not been keeping up; what's the obstacle to getting tested? Insurance companies not covering? Hospitals not willing? Patients not going in?
Management science fundamentally cannot be science. There’s nothing isolatable or replicable in humans in the workplace (or outside for that matter).

The best you can do is apply statistical approaches to arbitrary abstractions, and the main thing we learn when we do that is that return to the mean is the only thing we can really be sure of?
Silent Running (1972)

A space ark. A major stylistic influence on ones like Star Wars and Alien.
Here (below) is one of the referenced papers from that article, which basically asserts that the worst case long-term scenario (solar minimum) would give about the same amount of dose that the mice had in the study in about two years in space. Of course, a solar event would give a lot more dose quickly, but that is the kind of thing one can have a shelter for.

https://academic.oup.com/rpd/article/115/1-4/44/1600988

The interesting thing to me is that the dose to the mice in the study was so low, and still had measurable neurological effects. 30 cGy is not nothing, but in humans 30 cGy is about what a radiation worker might receive in 6 years at the legal limit, and is about 11 times lower than the lowest estimates for LD50/60 in humans (the amount of radiation which will kill 50% of the exposed population within 60 days). I don't normally work with mice, so I had to look up some info on them. Apparently the LD50/30 for mice varies a bit depending on strain, but it is in the range of 7 to 8 Gy. That is not that incredibly different from humans, because humans can have a similar LD50 if proper care is given.

Sources:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3743168/

https://dental.nyu.edu/content/dam/nyudental/documents/Irrad...

I don't know if the reason for the neurological effects at such low doses are because of the heavy ions used (which would be bad for space travel) or if it is because of the way it was measured in mice (not my field, I can't speak to that). But I note that airline pilots regularly receive career doses a bit lower to what the mice did (30 cGy ~= 300 mSv). And this dose is directly from cosmic rays, the same thing we are worrying about here.

I mean, sure, but chromium is still happy to spy on you, integrate with Google services, and contributes to the Blink monoculture. I'm just surprised that there are people who would object to Chrome on principle and not to chromium.

> The real culprit is the domain registrar and the DNS server software. Neither of those should be enabling invalid domains to be accessible.

They already don't. DNS does not forbid underscores, and places hardly any restrictions on labels.

Hostnames do forbid underscores, and that muddies the water quite a bit. While disallowing A-records on labels with undersores would make sense, a CNAME on a label with an underscore can point to a domain without one, and the one it points to may or may not have an A-record.

It is really up to the client to decide that a domain name is invalid for their use case, but clients don't want to disallow something that appears to otherwise work fine. And so we end up in a situation where none of the specifications are truly followed.
Can you share where my to-do list data is stored? In your cloud or locally on my machine and you never see it. Thanks! The idea is interesting overall.
>Universal means covering everybody.

Wouldn't this mean it is an impossible goal since unemployed people don't have it. This might sound a bit snarky, but I am being serious because unemployed does account for people who are working under the radar, often through illegal means. An illegal sex worker, panhandler, or someone doing odd jobs and taking straight cash payments are likely not covered even in places that would be said to have universal paid sick leave.
Nice insight!

While I agree there are some very hard trade offs that we have to make along all of those axes, I do also think there times when people aren't being ... thoughtful and you end up with situations that are far off the pareto frontier.
JSON is also missing a date type. Sure, you can use a string serialization but that's ambiguous.

It's also non-extensible so these types it's missing cannot be added without assumptions or overhead from convention.

Transit is a good solution to this.
It's not "oddly", it's deliberately deceptive and trying to exaggerate the problem to advance a political narrative.
> How does feeling Reiki establish it is real?

That's a good question. The subjective sensations correlated with various external events. What I mean is, I satisfied myself that I wasn't hallucinating.

> What sort of objective effect did it have?

Accelerated healing.

I've never tried to make a physical instrument to measure "chi", but the subjective effects of it on living tissue would be measurable with scientific instruments, I'm sure.

I'm not sure a different architecture would have mattered much. NeXT was trying to launch a Unix workstation right at the twilight of the age of Unix workstations. They got clobbered using 68K, but then at around the same time Sun got clobbered using SPARC, DEC and Compaq got clobbered using Alpha, etc.

Intel and Microsoft were busy eating the world, and one of the things that got gobbled up was the market segment NeXT was hoping to sell into.

The main benefit I've found to making the bed is that it shrinks your subconscious to-do list and helps you concentrate. If you make your bed, clean up the plates on your desk, and pick up your clothes from the floor, then your brain has nowhere to hide -- the only thing left to focus on is the task at hand.

It might be better than text formats, but it still encodes most things as variable-size and this is not particularly machine-friendly. A format with separate metadata and fixed length encodings for most of the things (eg numbers) would be much more efficient to serialize / deserialize.

The difference in means might be a useful measure of effect size if you are interested in comparing the results of two experiments, each with large n. It tells you what difference to expect if you repeated those experiments with new samples.

If, however, you are interested in the effect on a single observation, then the variability in samples/populations needs to be taken into account.

> no cross-version compatibility: Cap'n Proto, FlatBuffers

This is incorrect: Cap'n Proto absolutely allows cross-version compatibility, using roughly the same semantics as Protobuf. I believe FlatBuffers does too. (I'm unsure about the rest, haven't studied them in a while.)

> I'm using "self-describing" here to mean simply that you can recover the structure of the encoded data without a separate schema, rather than that you can attach any semantic meaning to it.

Protobuf, Cap'n Proto, and probably several of the other binary formats can parse data into a message tree without the help of a schema, but all the fields will be labeled numerically. MessagePack is only considered "self-describing" in comparison because in encodes human-readable field names on the wire.
You have totally misunderstood how bonds work on a "present value" or "mark to market" basis.

(All of the below assumes the bonds actually pay as agreed. Actual default risk is something totally different, and still present here.)

When you buy a bond and hold it to maturity, you're sort of right. If you put in $10,000 into buying a coupon bond, you will get the coupons plus the $10,000 back at the end. And if you buy a zero-coupon bond for whatever amount, which will be worth $10,000 at maturity, you'll get the $10,000 back at the end.

In fact, you don't even need to "assum[e] yields stay positive." When you buy individual issues and hold to maturity, you don't really care what everyone else's yields do; you get what you contracted for.

The problem comes if you want to actually sell out of your position, OR to know the true value of your position (essentially equivalent operations) along the way.

If you put in $10,000 into a bond yielding 5% coupon, and the next day yields spike to 10%, nobody will want to buy your bond for $10,000 any more. You most certainly have lost value. "Aha," the naif says, "but I could always hold to maturity and get my principal back!" Sorry. Do the thought experiment where instead of buying the 5% issue on day 1, you instead buy the 10% issue on day 2. Compare the cumulative sum you receive under each scenario. Investing on day 1 (at 5%) is strictly worse than investing on day 2 (at 10%).

Likewise, if yields instead crash from 5% to 1% on day 2, your position will be worth much more. Your $10,000 notional bond yielding 5% will net a buyer so much more than $10,000 spent on a 1% yielding issue that she will pay more than $10,000 for it. You have had a real gain, even if not realized.

The same thing applies to bond funds or indices but with much more smoothing across a portfolio. With bond funds, however, there is not even the illusory "X dollars out" guarantee; since they are marked to market every day you might well never enjoy a breakeven price.
> But it still seems intuitive that language should matter.

Am I the only one that thinks this is a naive assumption? They aren't really languages like English is a language--so much for intuition. Don't definitions matter to science? Does science carry a selfie stick? I'm suddenly keen on the antithesis of science or a less social science.
Could you do the same with time after 500 (or 1000) cases. There is a whole bunch of parallel curves that seem to be displaced mostly because of differences in early testing but otherwise show the same growth rate.
Getting back from Venus is as easy as launching from Earth: i.e., completely doable with present-day technology. The only issue is getting it there to begin with, but that's not really hard, though we'd probably need to launch several rockets here on Earth, and assemble stuff in space, to get all the mass needed for a single launch on Venus. Landing stuff on this hypothetical Venus would be much easier than on Mars, since this Venus has an atmosphere, and Mars only has an "atmosphere" (one that's 1/200 the pressure of Earth's, not really much of one), so we'd be able to use aerobraking, parachutes, etc. In fact, landing stuff on today's Venus is pretty easy, and the Soviets were doing this ages ago; the only problem is that landers didn't last long because of the heat and corrosive atmosphere.
Rather than criticize public health messaging for being at odds with popular political positions, shouldn't we put the onus on popular politicians and parties to embrace whatever health policy is best suited to public health needs?

Take full advantage of today’s multicore processors with Unity’s new high-performance, multithreaded Data-Oriented Technology Stack (DOTS).

DOTS makes great games run faster on multicore processors without the heavy programming headache.

DOTS provides programmers with a convenient sandbox to write safe multithreaded code for massive performance gains, while also optimizing thermal control and battery life on players’ mobile devices. By moving from object-oriented to data-oriented design, it will also be easier for you to reuse your code and for others to understand and work on it.

The new Conversion Workflow converts your GameObjects to entities with one click. At runtime, check the new Entity Preview Inspector to see how DOTS turns your GameObjects into entities
The other day I spotted in the SF Chronicle a picture from the 1918 pandemic showing a gathering of people manufacturing gauze masks. [0] Gauze appears to be out of favor as a barrier material today, although I suppose one could get creative and add a paper barrier layer. There are several viable materials for the goal of mitigating transmission. At any rate, this is something open to some guided improvisation with existing supplies.

The voting public in the US need to care as much about “keeping their doctor” as they do about keeping their doctor alive.

IsoAlloc author here. Thanks for reading the post and linking to the security properties. I plan to expand on those in an additional post and how I implemented them.

You're right that Electric Fence takes a different approach and is more geared towards finding bugs and isn't really suitable as a general purpose allocator. The easiest way to describe it is taking some allocations and placing them on their own page of memory, surrounding them with guard pages, and then setting the page PROT_NONE upon free so that any access results in a segfault. For a more modern attempt at this check out GWP ASAN which is doing something very similar but in Chrome across millions of installs https://chromium.googlesource.com/chromium/src.git/+/master/...

As for the allocator in glibc, a lot of its internal data structures either live on the same pages as user chunks or write meta data to free chunks. So using aggressive strategies like page permissions to protect that data is often not an option.
I'd like to hypothesize: the cerebellum "tunes" other circuits into alignment, which produces hebbian learning through synchronization. That sort of hebbian learning (novel synchrony between populations of presynaptic neurons) is both reinforcing and rewarding.

If I start from there and am looking to confirm this hypothesis (or disabuse myself from it), might you suggest a reference?
No, and that's a good point. I've lost a lot of faith in Amazon since it turned out that their Apple chargers were counterfeit (or were actually Apple but from a different country with different safety standards, or something).
If I may nitpick your response: the data from the Bureau of Labor Statistics is from 2009. 2018 data suggests 71% of workers receive paid sick leave. [1]

BUT, the data is highly skewed if you look at income. [also 1] The worst paid workers also have much less paid sick leave. Only 45% of the lowest 25% income group do. According to the BLS there were 130 million workers in 2019, thus leaving roughly 15 million people (130 x 0.25 x 0.45) without paid sick leave and likely without the financial means to go on unpaid sick leave or get medical help (like testing).

Also, the average paid sick leave varies between 6-10 (working) days. Suggested quarantine is 14 days. [2] Only 3% of workers have sick days "as needed". [3] This supports the argument that these circumstances make matters worse. I tend to agree to the general argument.
