Citrix is a little more than teamviewer. And can be encapsulated in a VPN as well.

Teamviewer on a desktop, probably with a shared credential isn't very secure. Knowing this though, I doubt that it was a teamviewer exploit. My guess would be a disgruntled employee since they knew what to get into to change chemical set points.

That's an understandable scenario and good on you guys for balancing the risks.

I think these days it is becoming a business need though. These systems are made by vendors who probably need remote access. Also if the plant has a relatively unsophisticated IT department then someone is just going to shove an AP in the ceiling so they can check things when they get called at 1AM.

Several ICS vendors like Tosibox and EWON make devices to accomplish this. I think Tosi has the more secure model, though I hate their proprietary dongles.

VPNs are also used pretty successfully here. Several large companies also don't let you directly connect to anything. You vpn in and connect to a machine with Citrix and then you can use whatever was setup for your there. Usually whatever version of Logix/Studio 5000 the plant is on. You have to talk to someone in IT to get your files moved in/out.

I think Amazon went a different direction and uses Versiondog to monitor their automation systems and check for changes. I don't work there or know anyone on their automation team so I'm not aware of the details.

Still, I think you can have external access and be secure. You just need to balance things out with your business needs.

My guess is that the hardware engineer that originally designed the board picked a reasonable part for a traditional auto OEM. Then at some point software engineering decided to log all the things. Nobody actually looked back at what the storage system longevity would be with this new lifecycle.

It's a dumb mistake, but not exactly an uncommon one. I made the same mistake early on and I have contract engineers that propose inappropriate storage solutions to me still on projects. Some very insistently. I think a whole lot of people that work on the embedded side of engineering treat storage as a magic perfect box.

This seems to be a form of magical thinking cloaked in science. It might even screw up them getting the real covid vaccine later.

The smarter move for the CTO might have been to get things going. Keep networking with other companies for a same level position and then peace out when it looks like things are going to blow up.

At least you would have some reputation intact. Now he is just the guy that failed, couldn't recover and will have a hard time going anywhere.

Realistically? Nobody is going to let DTCC go under, ever. But they don't want to be the one begging for a government bailout either.

Because your collateral requirement can vary based on the stock volatility.

Because if RH were to collapse the clearing house would be left holding the bag. And clearing houses don't have that kind of money. So DTCC (the main clearing house) going under would stop pretty much all trading in the US.

So the clearing house requires 100% collateral for some stocks now instead of up to 5%. RH can't afford that and GME has been eating up 50% of RH daily trades.

So the argument here is that bitcoin is valuable so the energy is not wasted. Which I guess is an argument you CAN make.

But doesn't really answer why we need blockchain specifically instead of something that doesn't need energy intensive digital mining.

It did not take much effort on my part to get on TRT with my primary care physician. Less than 200 ng/dl free testosterone and another test to make sure it wasn't a bigger issue. Once I started within a couple month I was amazed at how much better I felt than I ever had. Even my 20s. Like vitamin D people need more than you would think and guidelines are too conservative. I could have probably had fewer issue if they would have just juiced me up with this in highschool. Rather than just let me be chronically exhausted.

EFnet was always splitting every few hours. I don't really miss IRC compared to modern chat systems.

They also want to be able to refuel super heavy in orbit off another super heavy.

My guess would be it will still have a launch escape system for the passenger variant. So if the belly flop doesn't look right or if it doesn't stick the landing it just ejects the crew.

Better than average chance that The Thought Emporium [1] will be responsible for the first bioerror of this scale.

I wonder if this is because of the SoftBank cash crunch. Or if it's just nobody has figured out how to make money with Boston Dynamics. Though if the 1 billion sale price is true, maybe flipping BD is the only way to make money with it.

Resume based development definitely happens.

Yea, but we've always referred to them as president elect once it's obvious they will win.

Lex is great at bringing the conversation down to a more accessible level for people. He isn't doing a presentation at a technical conference. It's a combination of entertainment and insight into how the interviewee thinks. In a way someone that is technical, but not necessarily a super engineer, can resonate with.

He speaking style can throw people off. I'm pretty sure I have heard this style from other eastern Euro and Russian people. It doesn't bother me, but I can see why it can be grating to some people.

That's good that 5.7 fixes some of the wifi issues. I actually ended up forking the driver for our particular usb wifi device and hacking whole sections of code out of it. There were some optional things that would just randomly crash the kernel (4.x).

I have a couple contractors I bring in part time when I need some heavy lifting on the embedded or web side.

I have back-ported somethings, but really a large chunk of the products had terrible technical decisions before I started. I spent the first couple years just dragging the company back from the technical and financial brink. I'm slowly eliminating old products from our sales sheet in favor of ones I engineered. So it will eventually be ok.

I have been doing embedded for a number of years. I'm the only fulltime SWE at my company and it just gets exhausting managing 5 different products on completely different code bases/technologies. Plus a web portal that does device management and reporting.

So a big thing people should consider when building something to scratch. Am I making something I can use again when I make my next product. Its a much higher mental load if you have no commonality between products. Also it can cause problems for sales, support and management when they have to remember nitty gritty details about each of your very divergent products.

I'm not really surprised by this. The pay and the work environment are shockingly poor in nursing homes.

I think most of the restaurants that are thriving in my area are ones that were able to adapt to the new reality quickly. Many just completely transformed their menu's for takeout centric foods. The city here shut down roads and creating large social distanced out door seating. Enhanced all the alcohol permits for takeout, etc.

Restaurants can survive this. But what they were doing in 2019 is not going to work.

Isn't that exactly what the fed is doing for the wealthy right now by buying up the bond market? They are creating a furious amount of money currently with no end in sight.

But if you are a smaller business you are just going to be left to rot.

Clearly what was required was a two year study of COVID's effects and forming a committee.

Ah perfect, I knew there was a similar concept but couldn't remember the name.

Its always felt like a better near term way to boost around is just use massive (literally) platforms that have large installations of solar, batteries and electric thrusters. Have enough ballast that its orbit is only going to change a small amount when throwing something. Then you just keep thrusting until you are back where you were.

Electric thrusters are getting huge specific impulse improvements and the future seems to be pretty bright for them. We can trade time for efficiency essentially.

For interplanetary transit, just keep the platform running a circuit between the planet and earth. It's going to be way easier to hit your entry without getting into an unrecoverable situation.

Oh I'm not surprised at all. I'm guilty of this at my job as is everyone else where we work. What is our problem, what is our customers problem is always a hard question.

One of my big goals right now is to figure out how to extract problems out of customers in a useful way. (I seem to be heading more and more to product manager/product owner skill set).

Thought Emporium has a decent video where he modifies an Adenovirus to inject the lactase gene into the cells of his intestinal tract. https://www.youtube.com/watch?v=J3FcbFqSoQY
