Yet Linux is way more popular option both on the server and the desktop. Way way way more people and companies contribute. And it seems that BSD use is declining on servers? [1] MacOs is a unix but how does that help the BSD community, as most code is build upon it and the changes don't really trickle back. Companies just take, if you can do whatever you want with the code. You can wish that everybody shared back in a perfect world, reality proves this is simply not true. At least the company trying to influence development has to contribute to gain influence, and you can fork it (with their changes!) if you don't like that.

The GNU license at least somewhat protective. To each their own, but I would never release software under a permissive free license.

Yes the compromise is worth it. These are the best SoCs available on the open market. If we aspire to more open and repairable devices then we need to start somewhere, and we have to put our money where our mouth is. If volume goes up we get better open products. Luckily Pine64 is doing really well so much so that non geeks are buying their products (with all the software support problems that come with them)

I bought a pinebook pro and i have some SBCs. The PBP is perfect travel laptop with long battery life that can run on my phone charger. Firefox runs buttery smooth on Manjaro i3.

An incredible project pushing for open hardware.

Very happy with my pinebook pro and rockpro. The pinebook pro has amazing build quality and usability for the price. When my oneplus dies hopefully there will be a pinephone 2!

With uMatrix in "unless withlisted no js configuration" the test does not run. The noJS fallback does not progress. Probably means a pass :)

Unique fingerprint is really interesting upon enabling first party js. Fonts and gpu give lots of unique information.

Dont get the message to unblock ad providers that follow DNT. This trust is too easily betrayed.

Not really. Picked it up as a child, loved programming and tinkering. Had to choose between computer science and medicine. There are actually lots of things in common, debugging complex systems, building a mental model, abstraction, looking up solutions based on certain hints. Orthopedics is a highly technical field, working with implants, computer surgery, imaging and such so its very useful. Programming trains your problem solving abilities. I really believe everybody should have the opportunity to learn to code.

Not really a startup in the sense of a VC backed multi million dollar company but three working friends and me have bootstrapped a fitness websites with science based health advice, mostly free, to basically the largest fitness related website in the Netherlands. Currently employing people, which i think still sounds insane for a hobby project. https://www.fit.nl. 700.000 pageviews a month. App, 2 books, system for training and meal schedules etc. One now works full time as a lead/writer.

As a day job I'm a full time resident of orthopedic surgery. Busy days. I've done most of the programming of the website (custom theme on wordpress), product comparison engine and other custom pages. And server admin for discourse, mattermost etc

Some important findings:

- You have to care otherwise it becomes a chore. In this case it keeps people healthy. We give free advice that i think is pretty good, e.g on the forum, I love that part. The link with the day job is here. Lots of stuff i tell people during clinic hours applies here as well

- As its completely different it still feels like a hobby. Learning to do stuff is fun

- Clear separation of responsibility, do stuff you are efficient in

- A ticketing system for jobs, pick up stuff when you have time. Anybody can add to the ticket list but the list owner decides what comes first.

- Keeping the tickets bite sized. GIT to deploy, deploy often

- A time tracking system (Toggle) tracks time spent.

- Mattermost for private discussions and planning

- Meetups and fun activities to keep the group focused

- Managed main server (websynthesis) in case the website goes down and the other technical guy or me are unavailable. More expensive but less stress this way.

2nd year Surgical resident, part of my education to be an orthopedic surgeon. Currently working in a town 100km away.

05:45 wake up, quick breakfast and cycle to the train station 06:20 train. Grab the laptop, prepare for procedures or work on research 07:45 handover or 08:00 start of first procedure. Do timeout, grab a coffee while the anesthesist does his job 12:00 when lucky time for lunch behind the PC, administration 16:30 usually last procedure, handoff when on wards or clinic duty 17:00 see patients of the day, check for question from the new shift of nurses 18:00 train home. Do some coding for a company my friends and me run 19:15-19:30 home

Excerise, work on scientific papers or meet with the team at the office. Work on some points in the job queue. Sleep at 23:00.

Just a few more months and I'll change to a job closer by

These articles are always way overhyped. A lot more development is needed before it can even be safely used as a tool alongside radiologists. The dermatology example is an excellent one. It would be great to have a simple image classifier that can help the diagnosis before the clinical appointment.

Software on its own can't even tackle a 'simple' task as reliable 6 lead EKG (electric heart film) analysis yet. A chest x-ray has a lot more variables. Plus clinical variables as patient history etc can make a big difference in diagnosis on a similar image.

Brilliant piece of software. Perfect to gather data from different devices to backup in the cloud or to sync documents or a massive music collection.

The only thing missing is an encrypted external sync node so I can put it on a VPS somewhere

Very interesting article, his previous book 'The emperor of all maladies' is also highly recommended. A lot of medicine is not level III evidence or better backed.

As both a doctor (surgical attending) and programmer medicine feels not just like debugging a very complex non linear machine. Patient psychology is one of the hardest parts of the job. Is the stomach pain caused by a psychical problem or can it be functional? The use of protocols (part of the science) can help in catching non typical presentations of illnesses, especially if the patient is not adequate in presentation (drunk, very young, old, trauma etc).

But sometimes medicine comes down to an art, when you have the feeling something does not add up, you have to dig. The same with (older) attendings with very attuned diagnostic skills due to lots of experience that can help solve non-obvious cases.

The Selfish Gene - Dawkins, The Red Queen - Ridley

I've read these books midway through high school, already interested in biology and medicine. The depth and complexity of how life forms handle evolutionary pressure is mind blowing. Why you favor relatives over strangers, the competition between mother and child, progress through collaboration of genes etc. You see the world completely differently (after reading many more books on geology, genetics, anthropology, anatomy, cellular biology etc) afterwards.

For a novel: Cryptonomicon by Neal Stephenson,

Truely changed how I look at computers and encryption as a not mathematically inclined reader. Building a computer out of church pipe organ components etc.

Yes, some standard procedures on ASA1 patiens do not require a lot of sophistication. However do not underestimate how hard anesthesiology is, while 90% routine, 10% is incredibly complex stressfull scenarios in trauma/emergency, surgical complications, adverse events. Its much more than just heart rate, RR, oxymetry etc. Its knowledge about medicine interactions, organ systems, physiological systems and the skill to perform under immense pressure (trying to provide a permanent airway through facial trauma or large bore IV access for fluid replacements on a patient in volumetric shock) And while uncommon it can happen during standard procedures in ASA1 patients. I'd rather have the anesthesiologist close please.

As a quick sedation system these sound wonderfull though, for example for resetting joint dislocations in the OR where all emergency staff and equipment is already in place.

Because your immune system, a highly complex interaction between countless cells, is not fully determined just by your genes or your environment. There is also a stochastic factor.

Underestimating own skill and especially judgement of a situation as a young employee. Fear of larger organisations, complex processes that leads to avoidance of these type of projects. I've gained confidence over the years, now its easy. But it has led to regrets about missed opportunities. Also, not starting earlier with a side-business.

The United States can request an extradition for crimes committed by an individual(as argued under the US law). However this does not mean that the Netherlands has to comply. If a Dutch person committed a crime in the Netherlands according to the US, but its legal here, he/she will NOT be extradited. The same is true if the punishment is unreasonably severe according to Dutch law (death penalty.). For the latter there is a clause in our Dutch-US extradition agreements however you can still argue against this in court. (trias politica). It also stated in the treaty that the Dutch convicted can serve their jail time in the Netherlands. The punishment is then even converted to Dutch punishment standards.

There have been cases where it was argued that US electronic law (hacking and piracy cases) is not fair to the accused. This however does not always help.

This will however not help if you refuse a hearing on this. The article states: "Nomm agreed to waive his extradition hearing in the Netherlands"

Bittorent sync? Discoverability and multiple folder syncing has been a problem for me. I would be very interested in a perfect method to track and sync multiple folders on multiple computers

The complexity of the weapon systems goes up, and so does the price. The F-35 design already accepted a decrease in stealth capability, over for example the F22, to reduce price. Networking, sensor integration and related tactics is another revolution in progress that the F-35 does have. It's hugely expensive to be the first one to develop this.

Awesome, we use a lot of PET/CT/MRI fusion imaging for computer assisted surgery and have an EOS scanner (statistical shape modeling). Just really awesome tech. Good ultrasound -> CT fusion would, I think, be indeed be a major breakthrough, allowing easy matching / guided procedures everywhere in the body but also for us as a secondary check on CAS / robotic accuracy.

Yes it was a bit of a generalization, but i mean the practical use of the tool. The technology behind it is wonderful! For my specialty its relatively easy (bone being a rigid body). But this type of software already works quite well for lung, liver etc. With careful manual alignment it can work for soft tissue sarcoma (muscle) and other types of more movable tissue, providing a quick overview. Volume measurement is also an option. But as you say its always complimentary to standard workflow.

paradoxically there is also a risk involved with false positive diagnosis (be it unnecessary procedures, CT scans, surgeries, anxiety etc.) Also the detection window can be small from detectable to symptomatic for (especially) aggressive tumors. An example is the very difficult discussion on general population mamma carcinoma (breast cancer) or colon cancer screenings.

However being well informed and questioning everything is the very best way to be a patient.

Interesting article, glad the operation was successful.

The most interesting part of the article is not the advance in technology (nothing new, we've been using 3d prints as models for complicated fractures / bone tumours or even custom prostheses for years (academic centre)) but the low use rate of this technology by most hospitals.

The trick with overlaying follow-up scans is called image fusion and is easy and can be done by one-click applications (for example http://www.blackfordanalysis.com/) but outside of lung noduli i know of little clinical use. I've seen these types of mistake made before and trying to introduce it locally. Image fusion is also an awesome surgical procedure analysis tool (both for research and clinical applications), complimentary to the standard PA examination.

The patient education part is enormously helpful in practice. Cost per patient is however still high quite high for large models. For example a cardiac tumor model was printed with transparent plastic for around 500e. Our bone models luckily are a lot cheaper (non-clear plastic). When the price comes down i hope acceptance will improve.
