TetraScience | Lead Backend Engineer, Lead DevOps Engineer, Full-Stack Engineer | $100k - $160k + equity | Boston | ONSITE | http://tetrascience.com

TetraScience is a Boston-based SaaS company and rapidly growing startup that is applying the Internet of Things (IoT) playbook to lab research. We build both hardware and software components that allow research organizations to connect their existing lab instruments to a single online dashboard where they can coordinate experiments, monitor equipment parameters, and manage experimental data. With the insights and extra control provided by TetraScience, research organizations can more intelligently plan for future research cycles thereby alleviating equipment and process bottlenecks. In short, our goal at TetraScience is to use IoT to reduce the cost of doing science and while simultaneously increasing researcher efficiency overall.

Because our goal at TetraScience is to effect industry-wide change, we have intentionally built a team of passionately curious engineers of diverse backgrounds who support science and value scientific advancement. As a result, our team is an excellent counter-example to the claim made by Jeffery Hammerbacher the founder of Cloudera when he said “The best minds of [our] generation are thinking about how to make people click ads.” In a time when aspects of common consumer technology has created problems like filter bubbles and fake news, TetraScience empowers researchers to seek truth from fact.

We looking for a several roles in engineering: a Lead Backend Engineer, a Lead DevOps Engineer and a Full-Stack engineer to join team who love to build, who share our interest in facilitating scientific advancement, and who want to be an early and significant contributor to such an ambitious and impactful venture. See these and all of our available roles here: https://tetrascience.workable.com/ or email me directly dmorgan[at]tetrascience[dot]com.
On blockchains and why secure ledgers don't require proof-of-work
I should probably go back to playing this. I only got about halfway through the first campaign and never got around to installing heart of the swarm, even though I paid for it (like $20). I enjoyed the game, there's just too many damn games out there now vying for my attention.

I wonder how much of an effect being free to play will boost its popularity for esports. I know Blizzard was pushing for it.
With both the kernel and userland being replaced what, exactly, do you consider the Android OS to consist of?

I assume you're referring to the Java based frameworks and Dalvik/ART runtime pieces, but I would usually consider those part of userland, and your comment is a little unclear.
this only affects multisig
Sorry, I refuse to read white text on a black background.
For anyone unfamiliar with Minix, it appears to be a tiny OS:

> MINIX 3 is a free, open-source, operating system designed to be highly reliable, flexible, and secure. It is based on a tiny microkernel running in kernel mode with the rest of the operating system running as a number of isolated, protected, processes in user mode. It runs on x86 and ARM CPUs, is compatible with NetBSD, and runs thousands of NetBSD packages.[1]

Something about this [2] made me feel bad for the author, I can't imagine building software for a few decades, getting excited about a conference and then no one submitting any papers.

As much as I love The Lord of the Rings trilogy, I don't think I'd like to see Amazon take this on. In my mind, the Peter Jackson movies (not including the Hobbit series) were done so well they kind of put the definitive stamp on the Tolkien epic for me. I guess Amazon could mine some of the extensive Middle Earth history but there are so many other fantasy and scifi master pieces that have not been successfully adapted. Dune and Foundation come to mind or, for more adult fare, something like Kushiel's Legacy. How about bringing China Mieville's Bas-Lag and New Crobuzon to life on the small screen? I think Amazon should take a bigger risk than a LOTR retread.

They could do something like Fargo. The TV show exists within the same fictional universe but isn't really related to the movie.

I don't know - I've never thought to myself "I've had enough Tolkien stories represented in film". I'd love to see another representation.
His code is running on the vast majority of PCs produced, thats something to gloat over regardless of whether he agrees with the usage or not.
As with much of this, I can see amazon eating it all [0].

They have the marketplace and the tooling already, just artificially limiting scale.

That's true. Releasing other open source software using GPL software is much simpler. But if it's desirable to deploy closed source software GPL may not be the right choice unless you have time to sit down and consider the legal ramifications. In many cases there may be none if you use it in the right way but it should be and is being considered when companies decide consider whether or not to use open source software.

That part is often significantly simpler with BSD which is why it's significantly easier to just allow BSD and have a case-by-case basis for GPL.
>Do you have a better word for that behavior?

That's just people on the internet, my friend.

Is it mansplaining when men do it to each other or is it only if it happens to be a receiving woman? And do we call it womansplaining in the reverse direction? Do we pause the discussion until we know the genders involved so that we can use the correct word? Is it always about gender if someone responds to us in a less charitable way on the internet?

Or should everyone just make more charitable interpretations of each other's posts online?

Also, if socially charged topics are supposed to be ignored when embedded in another topic, what other topics are off the table? Can you say anything you want as long as it's tucked away in a small enough footnote? Or do we only walk on egg shells around topics regarding women? Is that the path towards equality in tech -- to only address topics that concern men?

If we have a responsibility to stand up when women are being attacked, then I think we have a responsibility to stand up when people dilute the issues that women face, like pulling the gender card when it happens to be a woman that receives the same sort of banter that we all have to deal with and ignore on the internet.

>It wasn’t an offhand quip like your gun control example, it directly related to the tweet she was talking about.

BTW the author is, as far as I can tell, a man: https://shkspr.mobi/blog/about/. He linked to the tweet and annotated it with the word that ignited this comment thread. The contention here is that many of us disagree.
Working Notes on Chalktalk
One use-case I can see where this would come up: ancestry/genealogy websites. Someone's grandparents may have been born in the Soviet Union, not in the modern Ukraine, from a cultural-historical standpoint.
Gmaps is so far ahead of anything available in 1983 that a comparison is almost silly.
you have good points. but what I belive gates was refering to at the time was what he was seeing as a threat to windows. if you ever have the chance, buy a used SGI workstation from ebay and play with the system. SGI had an affordable business workstations (pizza boxes) that shipped with irix5. the mais thing for irix 5 was that most of the in house applications (e.g. settings pannel, doc library, etc) were mozilla XUL+js applications! I kid you not. that was 1994 and the electron concept was alive and strong with mozilla 2. iriz 5.3 or 6 (i am sure i am getting the versions all wrong from memory) even had the first CSS implementation! and it was mostly to ease the transition from the motif gui framework to XUL.

this is what gates calles the figth for the web. saving windows. thats why they integrated IE so heavily on explorer. ...again, they did hit very hard in the actual internet ecosystem, but that was a side effect. and they would be silly not to try to take some advantage of that too since they were getting this for "free" while fighting for windows dominance.

"I've had enough Tolkien stories represented in film"

I don't know - that was pretty much my reaction to the Hobbit movies - which were pretty dreadful. I didn't even bother seeing the 3rd one.
There are in the Ember community. They do such a fantastic job of transitioning between versions.

I have had my complaints in the past when I don't touch an Ember app for a year, but for the most part, they provide ample "stepping stones" to bring the community along without too much anxiety.
It is not uncommon for smart, experienced people to suddenly become ignorant rubes in the context of lawsuits.

I might be wrong, but it seems PyO3 is more for going from Rust to Python, versus ctypes being for Python to C.
VR will succeed because it doesn't involve a whole suit to make work. That's why the Vive and Oculus ship with only two controllers and a HMD. No glove or shoes to be fitted correctly, put on/off, cleaned, etc. This is also why the Vive Tracker won't ever go mainstream for gaming. People aren't sticking 3 large sensors on their body outside of edge uses cases and now you have 5 things to remember to recharge. If good full-body tracking comes to mainstream VR, we'll be doing it with cameras, not wearables.

This is absolutely the wrong way to go about this. Its clear that Hyneman is trying to ride the VR hype to sell motorized shoes, which sound more interesting to me as a mode of transportation than anything having to do with VR. Especially if you can put in Segway-like logic in them to help with balance.

On the flip side, considering how long walks are most people's only form of exercise its probably a bad idea all around like those hoverboards or that new mini-segway. If I bought any of these I'd be cutting a lot of calories I'm burning and lowering physical activity drastically. Short range travel should be by foot and losing that will just make our obesity epidemic worse.
Recently I discovered how well sapGUI works from the UX perspective. It is essentially an glorified graphical 3270 terminal emulator which runs applications that very often rely on user entering cryptic but human readable IDs (there is lookup functionality integrated in essentially all such fields, but frequent users typically do not use it that much).

Another interesting fact is that the 3270/sapGUI/dynpro model is almost perfect match to how HTML forms work (with the inline lookups and such stuff being the small part that would require some trivial JS/AJAX). I don't understand why today's web apps universaly try to reinvent the wheel by being "single page", emulating desktop WIMP interfaces and such things when simple HTML would work perfectly fine.

Edit to add another point:
For our anime conventions I wrote our own online ticketing system. It has web interface for customers and general administration, but the on-site box office uses ncurses interface which intentionally has very ISPF-ish feeling to it, genral consensus of the staff seems to be that it is significantly more efficient and intuitive than web based systems used by other local conventions.
I thought the choice of medium was itself an ironic comment on the crappiness of modern computer usage. Tweetstorms are essentially unreadable, even with a tool like this thread aggregator.
There are definitely a good number of fantasy series that could be adapted to television. just like GOT the vast majority of them aren't household names. GOT certainly wasn't until it became popular on HBO.

LOTR, is there even enough content in the three books for a multiple season show? deviation becomes very difficult because the stories are widely known and all sorts of cliques exist around what is what. While the LOTR movies did good work with the books there is always the danger for Amazon that we would end up with a LOTR meeting a Hobbit style treatment so that it moves so far from the books that fans of the source material tune it out.

rehash, the fact they want to use a known story such as LOTR shows they are concerned only about money and not a good show. They are approaching it from the wrong angle
I can see it how it would work for forward/backward movement but not how it could possibly work for lateral movement like pushing off of one foot.
I don’t understand the premise that “Google (or anybody) is better at AI”.

How can anyone make such an assertion? Because Google or Amazon’s AI efforts are more visible? Has someone totaled up all the AI innovation (secret and not) at these companies and scored them? Are we talking PhD head count? What is the measure?

This reminds me of when I was fighting in Baghdad in ‘04 and everyone back home was arguing about a war happening on Mars or somewhere. They sure as hell weren’t arguing about Iraq because nothing they were talking about seemed to have anything to do with the facts on the ground. Facts that were nearly impossible for them to obtain.

This is a narrative not an analysis.
I agree with all of what you said, but I’ll just point out that I opened by saying that many people are definitely overreacting. Those are all reasonable points in general, though, and I don’t think they’re incongruous with what I’m saying.

"Hack" DNA. This kit is nice if you want some hands on molecular biology experience but really boring as far as what you'll do; mix some liquid in tubes and then watch ecoli grow on a plate.

CRISPR is really overhyped, there are a lot of problems with it still. No one will be hacking human embryos in their garage anytime soon.
Introducing AR view Shopping for your home
Perception of speed means a lot. I once was evaluating reporting apps back when people did reporting on the desktop. One app would render all the pages and then start displaying them. Another app would display each page as it rendered them. Which was faster? Overall, the first. Which felt faster? The second.
Great analysis. Altough i'm not sure that about the shopper side - since t-shirts are a self-expressive medium and not just a commodity like wine, probably there's value in offering a large selection.

And if we'd change the old model to something like this:

No prize. N designers competing. Top 1/3 win, and take all of the royalties of all the shirts in the competition, forever.

How would you analyze that ? would it be a good model ?
This is off-topic but you seem like a good person to ask: I've been thinking a lot recently about college football recruiting and machine learning. Do you know of any universities or companies working on this problem? Specifically, I'm interested in the possibility for lower-ranked schools to use ML to identify and recruit diamond-in-the-rough players who won't get attention from the top programs.
I'm pretty sure that Christopher Tolkien still owns the rights to The Silmarilion and has not sold off movie rights yet. That's why the hobbit movies didn't reference it. He was not a fan of the movies.
Personally I like pybind11 much better, it is incredibly easy to wrap even fairly complex c++ (and by extension c) projects with it. The best thing about it is its very good and thorough documentation. It is even fairly simple to autogenerate most of those bindings using libclang (The example he gave fall in that category, it gets trickier if you want to be able to subclass in python).
Another thing I realized it's nonsense lately: object oriented programming.

It's often an over-engineered bloat that only works for trivial Programming 101 courses (yeah the famous Employee or Bike class). But in 10+ years of programming, I found that OOP is just a complete mess (you end up with awful classes in your code like Service, Manager, AbstractFactory, and so).

I wish we could just use variables and functions, that's all we need really. :)
What license allows one to take credit for another's work?
More like, release your signing keys to us so we can fix the problem (and future similar problems) or go to prison.
Network latency can be one reason but I found the lack of optimisation to be a bigger factor. As long as a programme somehow works many developers won't try to optimise it. That gives us Electron apps which are easily 10x slower than a comparable native app (pgAdmin is a prime example).
I would have said that the Wheel of Time series might be a better idea than rehashing LOTR so soon, but apparently that is already in the works -> https://www.tor.com/2017/04/20/the-wheel-of-time-tv-serie-so...

Another one that might be interesting is Glen Cook's Black Company series, but that is apparently also taken... http://deadline.com/2017/04/eliza-dushku-star-the-black-comp...
Why are there no robotic airships available? They'd solve most payload and airtime issues that drons currently have. Also great for video since they're not as noisy as a quad and you could also turn off the engine.
I've experienced this. My first computer managed about 100 flop/s, or 3 Gflop/year. A modern PC can do that year's work in a millisecond! Yet when my current computer struggles to display a web page there isn't much interesting computation going on.

I ran into this a few weeks ago with a USB 3.0 thumb drive interrupting my Wi-Fi network communication on my PC.

I fixed this by putting the USB 3.0 thumb drive through the washing machine in my pants pocket. After being washed, the thumb drive no longer works, but my wi-fi is working great now, thanks to the washing machine. Problem gone.

That's not really the way it is. It is possible for something like this (these two being related) to not appear on wikipedia, and it is also possible the commenter is not able to come up with something interesting on google (maybe he suspects he's not using the correct search terms).
(Aside: it doesn’t matter whether B calls A; linking with it is sufficient. In your example, B’s source became GPL licensed because it was linked with a publicly released A)

My logic was incorrect. I assumed that the exact same source code for now GPL licensed B from earlier revision revisions would have to be GPL licensed, too (and because of it, anything linked with that, linked with code linked with that, etc.).

However, licensing (unlike copyright) doesn’t work that way. Copyright owners can even release the exact same set of source code 7nder multiple licenses.

My conclusion still stands, though. Companies are right to worry about using GPL-licensed software.

I'd be interested as well. Some of the 3rd-party DJI software can do geofencing.
Heh. Overflow? Funny (maybe not to "winners").
I love the Indian govt. So shortsighted. Something like bitcoin cannot be killed by them singlehandedly. Similarly, with big players like Russia and USA potentially playing against each other, it becomes a game of prisoner's dilemma.

This kind of dilemma exists in despotic and dictatorial govts regarding the Internet. If they don't let their people have access to Internet, then they risk being left behind and potentially weakened against their enemies. If they let their people have the Internet then they risk getting their populace awakened.
Because the library you are trying to use it is written in C / C++, which is more likely than that is written in rust.

Ah okay, thanks for the explanation. I've heard of multi-sig wallets, but wasn't quite sure what they actually do. From what I can tell they are supposed to be more secure, so it is a bit ironic that this is the second time multi-sig wallets have had issues.
To be fair, most likely someone's teenage son added a scroll listener when he built the small church's website before going off to college.

He'll almost be 100 then. The chances of a man reaching that age are pretty slim.

Not sure why people pay attention to this guy considering his expertise is in tech, not medicine. His analogies are often mockingly simplistic (no Ray, cell phone adoption rates have nothing to do with medical research and longevity) and seems to be the standard bearer of the kooky futurist stereotype.

I feel my life got a lot easier when I dismissed guys like this and accepted a more dignified idea of dying.

Tax collection and tax incidence are indeed separate issues.

The tax incidence falls on owners - probably at least until profit taxes reach ~80% or capital became magically very scarce for some reason that clearly doesn't apply to the present day.

> I didn't try to promote or define subjectivity, I challenged you to define an object without making any references to something subjective

I can easily posit an ontology that references no subjects. Just because I formulated said ontology from sense perception doesn't entail that it references subjective concepts.

> Mind you, I'm not saying objects and subjects are real, but that they are co-created by the mind and as such are equally unreal as far as representing what actually is.

Except as per Moore, this sort of skepticism necessarily presupposes the very knowledge that it attempts to undermine, and therefore it contradicts itself and is literally false.
