I was working full time and did my PhD at the same time. My employer let me do the work at work (there was a lot of overlap) and only had to travel to university to take a few classes (made up the time by working longer hours and sometimes on weekends) and meet with my academic advisor. I also had an advisor (mentor) at work that I would interact with on a daily basis. The downside was that I had to pay tuition, but the company paid for some and the rest I paid from my salary. I still made more than a graduate student at the institution. Overall, it was a great experience. I would recommend doing it this way if you are interested in going into industry and you already have a built-in job. I was upfront when I got hired and told them I was looking to do a PhD and they agreed.

Sure. A lot of the playground are kinda dull today especially as the kids get older. My kids learned to climb trees in my yard and in the parks around. They also sometimes climb on top of the playground elements to get their thrills.

A few jobs back when I was working for a fairly large telecom company there was a similar kind of thing for the software department. I was in hardware but sometimes I would interview software people if they were hired to participate on my project. The software department asked me to rank the interviewee on various categories and give a score. If the total score from all interviewers were larger than some value, they wouldn't hire them because they didn't want them to get bored and leave. Needless to say, this process frustrated many people. It was not consistent across the company though. For the hardware department there was no such system.

This! I've been doing BJJ for 8 months now and I am addicted.

Brazilian JiuJitsu. After trying and failing for many years to exercise, this sport keeps me coming back. I feel the difference from before: better posture, strength, and flexibility. I also feel happier.

Not sure about that. If Matlab is their main competition, then they are much cheaper and you get tons more (that you may never use but its there...) for the price of just Matlab's base software. The downside is that the engineering community by and large uses Matlab because it's what the legacy code is and it is taught in school. I've used Mathematica and I enjoy using it (and Python) more than Matlab but at the end I have to use Matlab because that's what my colleagues use.

This reminds me of the documentary Race to Nowhere. They talk about the high suicide rate amongst teens due to burn out from school and how some were brought back from the brink. https://en.m.wikipedia.org/wiki/Race_to_Nowhere

It doesn’t seem to be the default anymore on iPhone. Mine was set to private and doesn’t show on the feed. I got Venmo about a year ago.

Only 150 people with 35 intubated. There are several factors that could explain (at least part of) their results and one is age. They do mention that age denotes a statistically significant difference between intubation and no intubation under Table 1.

It is not easy to tell but depends on how you read this it could be that they had some data and they went fishing. You can always find correlations by fishing through the data and looking for when does the p-value become low enough [0] but its not a valid way to do data analysis. It is also data from one hospital and one region. I don't think you can draw too many conclusion from this one study.

It is published in a journal with impact factor of 6.36 and a metabolic journal. If this was a significant finding I would think they would publish in a higher impact factor journal.

So overall it calls for some skepticism. [0]https://en.wikipedia.org/wiki/Data_dredging

None at all. When the democrats are in office you kick out far right. When the republicans are in you kick out far left. This way you avoid getting regulated. It’s a free country and your company it’s all good. It opens up opportunities for other companies to come in and take the business. Oh wait... are you a monopoly?

Yeah you are right. Instead they burn down businesses and riot in the streets and go attack far right rallies. It seems both far left and far right are embolden these days. No science on either side. No one wants to listen to the other side. Not a good situation.

Here is the Nature Communications article. https://www.nature.com/articles/s41467-020-19183-0 Before we get too excited: "In particular, we deliver light-absorbing graphene particles (100–1000 μm in size) to the space between the electrodes using a slowly diverging laser vortex beam (see “Methods” section) propagating through a round hole in the first electrode." This is far from self contained. I know that in the past people seeded clouds [0] to get rain but this is a lot of extra work that's needed. At that point it may be still easier to use the high power laser and guide the discharge. Saying this technology can help reduce wild fires is a bit premature but I wish them all the best of luck.

From the credit card. They will then deal with the company. So then it becomes their (the credit card company’s) problem.

Similar issue with Aeroflot. They cancelled my flight and issued a refund but said it would take weeks. After 4 weeks called my credit card company and they issued a credit to my account immediately. The credit card company said that I could have called after a week, didn’t have to wait 4.

Yes. Sorry. Ultralight can have one seat. Sport can have up to two.

Agreed about the student pilot not getting an endorsement on an on-going basis. It's too much of a risk to them.

You can fly a category of airplanes called ultra-light and you don't need a pilot's license. You can take a single passenger. It is based on airplane weight and horse power. Different countries have different standards. https://en.wikipedia.org/wiki/Ultralight_aviation

As a student pilot in the US you can fly without a passenger but also with other restrictions like your flight instructor has to give you an endorsement to fly and most won't give you an unrestricted endorsement. It is really there to get you a certificate and not as a way to bypass it. All other require a certificate (technically it is not a license but rather a pilot certificate). https://en.wikipedia.org/wiki/Pilot_certification_in_the_Uni...
