Lumicks | C++ & Python Developers | Amsterdam, NL | FULL-TIME, ONSITE, VISA | lumicks.com

Lumicks is bringing novel tools for single-molecule biophysics and cell avidity to market, enabling scientific researchers across biology and medicine to unlock new types of experiments.

Our primary technology, C-Trap, can be used to "grab" a single molecule, and apply precise mechanical forces to it. At the same time, one can visualize the molecule using highly-sensitive fluorescence microscopy. Our customers use it to watch DNA being copied by the molecular machinery of the cell, or observe molecular "engines" walking across the scaffolding structures of a human cell. Lumicks systems are currently in use in opinion-leading labs across the globe, including Stanford, Johns Hopkins University, Tsinghua University, NIH, Max Planck Institute, TU Delft, and Imperial College London.

We also produce z-Movi, the only instrument that can directly measure the overall strength of interaction between cells ("avidity"). This new technology, based on acoustic waves, could have an enormous impact on research in immunology, paving the way for new therapies for cancer.

We're an academic spin-off from a research group at VU University Amsterdam. We care deeply about providing our users with easy-to-use, reliable software that actively supports Open Data and Reproducible Science. To make this happen, we're looking to expand our software engineering team with additional:

- C++ developers -- https://lumicks.com/vacancies/c-software-developer/

- Python developers -- https://lumicks.com/vacancies/python-developer/

We use the following technologies. When applying, it's fine to be familiar with a subset of these:

C++17 for the core code, Qt5 for the UI and Python 3 for bindings. CMake builds everything. Libraries we use include abseil, asio, caf (C++ actor framework), catch2, cereal, fmt, hdf5/highfive, opencv, ranges-v3 and spdlog. Our GUIs are a mix of Qt widgets and QML (we are migrating torwards the latter). Our Python bindings are implemented using pybind11.

For Python, we use Python 3 with the usual scientific Python stack: scipy, numpy, matplotlib, h5py, jupyter.

On the hardware side, we have lasers. Lots and lots of lasers.

Every other F100 was outsourcing IT like crazy in the mid-2000s because of that Harvard Business Review article that talked about outsourcing everything non-essential to your primary business. Meanwhile, Werner Vogels (Amazon CTO) thought that was a stupid idea because every business was being transformed by its IT and that it's a revenue multiplier, not a cost center (something that every other decent person in the rank and file of IT has believed since... ever). The whole "digital transformation" boom that swept the F100 in the past 10 years is essentially back-tracking on all these divestures and off-shoring efforts.
It also sometimes "corrects" queries, forcing one to click to rerun the original query as intended. This very infuriating.

I'm into design myself, but not so much into designing for SaaS, form layouts and stuff like that. That's why something Refactoring UI or Tailwind UI is interesting, they're designed by people from that space, they're basically selling their design domain knowledge.
Exchange risk is a real thing. For all the positives and fun that Robinhood provides, dealing with immature platforms that aren't backed in full by the faith of the US government and social contracts is in most cases not worth the cost.

$10k a month is a 'sustainable full-time job' for a senior developer once you factor in health insurance and the additional 7.65% self-employment tax.

> tries to do

If one were unconstrained by development effort and sales, concerned only with deep transferable understanding, I wonder what one might explore with representations that were less cartoonish, more physically realistic?

Directly rendered electron density? With "bonds" implicit. Plucking, distorting, ripping, and assembling molecules grabbed by their nuclei. Or poked with others. With realistic and explicit time/space scale and dynamics. Captures of ab initio simulations, with their rich complexity and ambiguity.

Nuclear density, with alpha clusters, liquid drops, interesting shapes, and again, a hands on realistic dis/assembly and messing around.

It's pragmatically hard now. But arguably possible. So now, or years from now, there exists the question of how might it be used, how much might it help. How hard should we be trying to make it happen some years sooner rather than later. But we don't seem institutionally set up to explore such questions.

Algorithms that recognize people in photos aren't (and probably never will be) 100% accurate, especially in this context (people in the background of photos will often be partially obscured, poorly lit, maybe really small/far away, etc.).
I didn't say he is angry, my main point was not advertise for free for a company that is built off the work of a single man, especially when it's FOSS, especially when it's a technically piece of genius like WireGuard, while not supporting the man himself. There are known ways for companies to market their paid product, it's called ads.
Does Braintree support this? I’m currently in a situation where I need to ping pong between stripe and Braintree and this would be the perfect solution.

We're hiring backend Python and Java developers, frontend Angular developers, QA engineers, data scientists, data engineers, product managers, engineering managers and more. Job openings can be filled in Santa Clara or Charlotte, North Carolina.

https://hire.withgoogle.com/public/jobs/leantaascom

Everyone complains that our healthcare system is inefficient and costly. If the idea of working with smart people to actually solve the problem and make it significantly better for our future generations seems worth your time, reach out to me directly at hireme@leantaas.com and I'll put you in touch with the right hiring manager.

We're a Series C funded healthcare tech company based in Silicon Valley obsessed about making our hospitals more efficient with data science and machine learning. 65+ healthcare organizations including the likes of Stanford, Duke, NYP, Dignity, Memorial Sloan Kettering, Tenet and more rely on our products to lower patient wait times, improve staff satisfaction and overall financial performance.

Our team includes successful entrepreneurs, engineers, product managers and data scientists from Google, LinkedIn, Apple, Symantec MIT, Stanford, UC Berkeley, Google, McKinsey, and more. We've raised $55 million to date from top tier VCs in Silicon Valley. CBInsights recently named us among the top 100 AI companies in the world.

We're fully cloud hosted on AWS and leverage modern tooling and automation to produce high quality code - and we ship every week!

Our vision is to build an "Air Traffic Control" for hospitals - a centralized command and control center that routes the right information to the right department as patients flow through the system - if we get that right, we'll be able to significantly make our hospitals more efficient and eliminate waiting and wastage and solve the problem once and for all.
The OP said they were in Wuhan in November when they got the flu.

It would make sense for the doctor not to know what it was at that time. Covid-19 wasn’t a concern until January.

We didn’t have these quick tests until ~February.

I've worked at both level -1 and level -3 organizations. -3 is usually doomed because the organization is actively self-sabotaging and the money is going to run out quickly unless management identifies the toxic actors and gets rid of them. And that rarely seems to happen.
This is neat, I've been daydreaming about this being possible to make for years now. Practical? Probably not, hard to beat a multi million dollar budget, but still, neat.
Generally it will only fail if your machine is getting forkbombed. If you are currently developing an application that forks you are most likely the one doing the fork bomb.
I wouldn't say you 'countered' OP with that quote, but you did add some very pertinent and helpful info. From my perspective, though, your info is syngergistic with OP's, not counter to it.
What is the support like for storing payment information with a site? Ex: example.com wants to store my payment information to help expedite future purchases.

I ask this as someone who works at a large online retailer whose CISO has specifically asked to keep them informed of things that could improve our security posture around payments. Inability for a site to store payment information would discourage large sites from supporting this, or at best slow the implementation and support of it.

Apologies if this is somewhere in one of the two documents. I tried to skim through the ~150 pages to find related items.

Really? I have almost the exact opposite opinion of it. If anything Pin validated the construction of Rust the language and it's approach to structuring types in the standard library. We got to express something at the type level without implementing it as some kind of custom language feature. It's complicated, but it's describing a complicated problem so the complexity is inherent. And luckily, most users will never have to interact with Pin anyway.
Too little! The cost of replacing an iPhone dwarfs $25.

The reason they settled was likely due to guilt, because proving innocence is cheaper than $500M. They should not be allowed to get away with a slap on the wrist

Python2 implicitly converts int to long and str to unicode:

>>> 2**100
1267650600228229401496703205376L
>>> 'x' + u'y'
u'xy'

All Pythons implicitly convert int to float and int or float to
complex:

>>> 1 + .5
1.5
>>> 2 * 3j
6j

Methods like list.extend now, in recent versions of Python (since
2.1), accept arbitrary iterables rather than just lists; it's more
debatable whether this is an “implicit type conversion” or not.

>>> x = [3, 4]; x.extend((5, 6)); x

The github trick is pretty cool. I'm running into an issue though where it opens the link but in the wrong repo. Have you ever experienced that?
If it's that easy, then the original submitter can post that link just as easily.

I appreciate your first comment. I appreciate the reply supplying the substantiating link more. And this particular subthread is regrettable.
It's.... a bit hard to define my current workspace. I do software development but a lot of that development is on legacy applications using some obscure API, perhaps a super old version of a known open source project that nobody uses anymore, or simply dealing with an application written two decades ago in C and I have to know specific things.... and I'd have to say searching on Google is just handy when it comes to this.

It's not easy to describe I guess. For my normal "John Doe" usage I have no problems using DDG. But when it comes to work where I need to narrow it down the best I can I guess Google will always come to the rescue (but not always, haha.... nothing like dealing with undocumented libraries).

I wish it was just language-specific behaviors at least I know there's always plenty to search on but... it's a little bit of everything.

The code posted by dbaupp shows how violating Rust's immutability/exclusivity guarantee can also violate the lifetime guarantee. The implication being that the lifetime guarantee depends on the immutability/exclusivity guarantee (as supermatt claimed earlier).

It's a good example, but I'm still not enirely convinced that the implication is necessarily correct.

I wonder if a sufficiently smart compiler could not detect this particular special case and relax immutability/exclusivity in other cases where no references to the internal structure of a value exist, or if it could even keep whatever r is referencing alive to uphold the lifetime guarantee.

I realise the latter could have some undesirable side-effects wrt memory usage and it raises ownership questions if there are multiple such references. It's essentially what persistent data structures in functional languages do and it may not be a good fit for Rust.

The reason why I'm even interested in this is that Rust can sometimes feel restrictive in situations where having both mutable and immutable references or more than one mutable reference to the same thing is reasonably safe, such as in the local scope. Obviously people are working around mutability restrictions by using indexes/handles instead of references, but that doesn't seem any safer.

I'm not aware of any aftermarket EMS's using FPGAs, and there are quite a lot of them. The engine position sensing isn't something that requires a lot of specialized hardware: The sensors are usually one or two reluctors or hall effect sensors that give, say, 12 to 64 clock edges per engine rotation. Determining engine position is pretty easy with most microcontroller's built-in timers. I know that megasquirt, and freeems use hardware timer capture inputs for this purpose.

It is certainly something that is easy to cause engine damage if you get it wrong, but the application for these is usually offroad vehicles. There is a community of people that do convert their engines to use these systems. I've eyed rusefi for a while, I've personally used freeems, and even started to write my own EMS for fun (https://github.com/via/viaems/).

I don't think engine position sensing has changed even with the most modern engines, though the direct injection engines certainly have more specific timing requirements for fuel injection.
It's still not clear, but I doubt they will fully ditch it. My understanding is that Hangout Chat is going to replace it, but the current iteration is very enterprise centric (feels like Slack). The fact that they still haven't killed Hangout makes me think that they will adapt Chat to be closer to the old Hangout and swap the two.
