I would also recommend this book: https://nostarch.com/gettingstartedwithfpgas

And it's associated starter FPGA: https://nandland.com/the-go-board/

If you outgrow this I would recommend moving to some sort of Xilinx Arty Spartan board

I loved smith charts during my microwave classes in college. I've always felt like there should be a fun game based on the mechanics of using a smith chart.

If you (or anyone else) are interested in getting into embedded email me at my username @ gmail. We're currently looking for a couple. Coming from Java/Python is a plus

I almost never turn on my camera unless I'm hosting a status meeting (and I don't expect other too). Most of my 'video' calls are with one or two other people debugging something and sharing my screen. When compiling and running stuff my pc is already struggling, no reason to bog it down more with someone's face.

The only people that seem to care about people turning on their camera are those who's job is to communicate with people all day long. I get it, but at the same time stop trying to change others behavior to make you happy.

It's a lot like those who hate work from home because they no longer have a social life. Don't make ME commute to work and fake 9+ hours of work so YOU can have a social life

I know you're asking specifically about results from on board the ISS but here's something more broad https://en.wikipedia.org/wiki/NASA_spinoff_technologies

I think this is a result of adults making up a much larger share of gamers and profits to gaming companies.

I've noticed myself doing this and I can pause it if I try but I don't think I can turn it off. Playing games as a kid, it was all about exploration and doing fun things. I didn't beat many games but I played a lot of them. As an adult, I need to be setting goals and earning achievements. There always needs to be something I'm working towards.

It's fun planning/achieving at first but after a few weeks it just feels like i've given myself another job then i get burnt out and reset.

I haven't played battlefield 2042. I bet you're right that portal mode is fun but I'm willing to bet if I was to play I would probably start to express the same sentiment that there's no point in playing portal mode if it doesn't help me progress in the game. It's stupid and I have a hard time admitting it but it's true.

Sometimes I wish I could just enjoy a game for what it is and not be thinking about "what next?" or "what does this accomplish?". I think its just because we're adults (and probably because we have fully developed prefrontal cortexes?)

+1 I started using this to keep track of university assignments. 8 years later it's still my go to for personal things. It serves a different purpose then a calendar but the two together solve everything I need

I've always thought it was like a smoke shop. They say their products are for tobacco but everyone knows what its really for. Same with VPN, they say it's for all those things above but accessing geo-restricted content seems like the real reason.

To your point about others not teaching well to preserve their status, I'm sure it exists but not that prevalent. I think people who have known something for a long time just forget how to empathize with not understanding what they've known for so long.

For this reason alone I think this is why fellow students tend to be much better at tutoring/helping each other instead of their professors.

The issue is that the scanning happens on your device just before upload. So now your own device is scanning for illegal activity _on_ your phone not the servers.

The second issue is that it will alert authorities.

In regards to CSAM content those issues may not sound terrible. But the second it is expanded to texts, things you say, websites you visit or apps you use it's a lot scarier. And what if instead of CSAM content it is extended to alert authorities for _any_ activity deemed undesirable by your government

It will probably work as well as it does for murderers. There's not really a demand for murder so there's not continually new people filling their shoes when they get arrested.

Drug dealers on the other hand will never go away no matter how many you arrest. There will always be more people willing to buy drugs and a new dealer ready to step up and make a profit.

I wholeheartedly disagree. I have an undergrad and masters in Electrical Engineering. I work as a Digital Signal Processing (DSP) Software Developer. On the lower end I've improved DSP C code by rewriting important sections in assembly. I've had to debug with JTAG, logic analyzers and instruction accurate simulators. On the higher end I've had to use Matlab and Python to create a tuning tool to tune active noise cancellation (ANC) on one of the most popular selling ANC capable wireless headsets to date. I'd like to think I have a solid programming background.

I have been trying to write a basic webapp that's a duolingo clone for piano chords on and off for years. Every single time I try it ends up falling apart because there is so many things to tie together.

I started with plain html, css, js. It quickly grew to the point where every change was breaking something else. Clearly I need to test so I try to learn to how test web code. Documentation and forums everywhere only help with testing assuming you're using a framework. I get busy with my dayjob again and don't pick this up for another few months

Screw this, I really liked the rails tutorial by michael hartl I completed in 2013 I'll give that method a shot. Turns out nothing from 2013 is relevant anymore. Server side rendering for a dynamic front end is confusing as hell. I have similar problem trying Django. Keep in mind every place I look for help react and various js backends are being shoved down my throat. I get busy with my dayjob again and don't pick this up for another few months

Ok fuck this I'll just bite the bullet and learn react and backend js. Now I'm in webpack hell. every problem is solved by making further complicated changes to babbel and sucking in 100 more js dependencies. I still don't have a SQL database integrated, authentication, a front end or tests and I'm miserably confused. I get busy with my dayjob again and don't pick this up for another few months

Time to give asp .net core a try. Holy shit one command gives me an entire hostable front end and backend with authentication. I'm so close. Oop nevermind there's so much black magic in this sample app I have no idea how to start associating my database schema with the logged in user. The sample does so much for me, I barely understand how to extend it. I get busy with my dayjob again and don't pick this up for another few months

Finally I just accept that it's all too complicated and try to integrate a react front end with firebase. I'm still struggling with so many issues but I've never gotten this far before. I can finally see the light at the end of the tunnel. I get busy with my dayjob again and don't pick this up for another few months

There isn't a single tutorial/documentation/sample that I can find that uses a database outside of sqlite, a backend, a front end, authentication, unit/integration tests, and how to host it all. As soon as I get two or three of them together it becomes such a mess that I can't complete the rest. This is the bare minimum for a webapp. Everybody expects to be able to login and view/modify/add their data. Every developer expects to be able to make a change, run some tests and push to production.

I don't think I'm incompetent. Given enough time an energy I could get any of my above attempts to work. But I have a dayjob and a social life and want to have a bit fun toiling around with a website on the side. A webapp is not very simple. If it is then prove it. Show me your codebase and explain it to me. My email is in my bio. Or at least link to someone that has

I've noticed something similar in University that was very frustrating for me.

Freshmen and Sophmore year all math classes had tens or hundreds of problems that get progressively harder and bring out every corner case e.g. take then derivative of x^2 then 2x^2 then x + 2x^2 then sqrt(x) + 2x^2 + 3x^3. Eventually you could derive the most archaic equations

Junior and Senior year Engineering homework is like 2 Epic questions with 10 parts that feed into eachother. I would have learned more and been more confident if they gave like 10-20 starter problems and then one final epic one at the end.

I feel like this is similar to the story of a pottery class having half the class make as many items as possible while the other half had to make just 1 perfect piece. The group that was targeting quantity actually produced better pieces then the group that was targeting 1 perfect piece

edit: typo

Thank you I really appreciate your encouragement. I understand why you may want to be anonymous and especially for the example you gave. I don't think that's my blocker however I can certainly give it a try.

Organizing my thoughts and second guessing everything feels like the main blocker. If you look at my response to a sibling comment, it's worth pointing out that it took over two hours to write (while in work meetings with only a few times I needed to chime in). For some reason a response like this only took about 10 minutes. Perhaps because this is more of a thank you with a fact/comment. The other is much more of an idea/concept.

While a bit of a tangent I think this is a wonderful exploration on reasoning how complex writing things down can be. Remembering a dream is a very apt comparison, it all fragments and falls apart the more you try to put it together. I believe this is why writing can be so powerful though. It forces you to connect and clarify everything.

With all of this said it's incredible that people are able to post on social media often. It's a crushing amount of mental energy. You could chalk it up to others not being critical thinkers but that just feels like a subconscious way to insult them and simultaneously compliment yourself.

I had to tell my girlfriend when we first started dating that I usually see her texts within moments of getting them. However if I don't respond soon then I'm not trying to play mental games, build tension or whatever. I need time to formulate a response and type it out. When she sees me text others she is appalled at how difficult it is for me. I can coordinate plans, answer a short question or relay facts with no effort. The second it becomes a conversation or small talk I just lock up. This is with everybody not just someone I'm attracted to.

I'm hesitant to declare this about myself because of all the biases that can be at play and what not but I generally feel I may be similar.

Sure once I make a post I'll check back for responses/likes but it's never on my mind when I create the post. More importantly I never find myself wanting to post anything. In fact its borderline difficult. I hate having to put my thoughts down and try to be conscious of how other's might perceive this. This is becoming increasingly frustrating as I type this right now.

I generally feel like I have nothing significant enough to say to put myself through the effort to write it down. I much prefer verbal. Maybe it's not so much a resistance to social media addiction as much as it is despising the process of writing.

I almost did this exact thing. I guess I do regret it but there's no way I would have ever held on to any of it after it hit $1000/ea. Maybe less. It's a lot easier knowing I passed up on a couple hundred thousand dollars and not tens of millions of dollars
