  1. Some days it just isn't a good idea to open your front door.  Happy Monday!  :)

  2. Got to sleep in late today, but also working until midnight on a Friday. :(

      This was a one-day thing supporting a special event.  Looks like it isn't happening though so I'll likely be going home early after all.  They did feed us at work too.  I guess I should be thanking ISRO?  They might not be in a mood to appreciate it much at the moment however.   :(

      One day working late is one day too much for me 😂

      Yeah, too bad for India, quite a lot of money down the drain, but let's see what the reason was.

      Yeah, too bad about the lander but they still have the orbiter, which has most of the science instruments on it.  It would have been great to have the lander (and rover) to ground-truth things, but it isn't the end of the mission by any stretch.  ESAs MEX lost Beagle, but years later were still tracking them every day.

  3. Just thought I'd poke a bit at an entry-level threadripper system.  I know, that's kind of a strange thought when all the gamers are still salivating over a i9-9900k for the single-core performance, but it turns out that a low-end 1900X CPU, 2 sticks of 16GB, 3200MHz DDR4, and a really (like, really really) nice motherboard can be had for less than $1k.  The motherboard is totally overkill for the initial RAM and CPU, but with AMD it should be upgradable for many years.  Maybe in a year or so - when the bleeding edge has moved on - you replace the 8-core 1900X with a 16-core 2950.  At some point you buy another couple sticks of RAM.  Did I mention the MB supports quad-channel?

    If you already have a decent case, power supply, etc., then swapping out the guts for an 8-core system (that would have been considered a monster just a couple years ago in the old Intel era) might make sense.  With that MB you could go all the way up to a 32-core/64-thread CPU and 128GB RAM.  It also has *3* nvme m.2 slots, not to mention dual network ports (one of them 10Gb).  For games.. ok, maybe not so much.  (Yet?)  But if your workflow includes things that might benefit from a lot of cores..... maybe.  It is also quite possible I'm just a tech geek looking for new toys.  :D

      Sure.  I don't mind advising, and I like planning new builds, though do I tend to spend way too much time obsessing over little details.  I'm also not a "cheap at any cost" advocate.  The systems I build for myself tend to be a bit on the pricey side.  (My current system, for example.)  Unless I'm building a system for a specific task I like giving myself a bit of elbow room.  Consider yourself warned?  :)

      You get what you pay for. Generally speaking, if you just go with cheap parts, they probably won't perform as well or last as long. 

  4. Happy Landing Day!  My dad worked on Viking back in the day so I got a day off from middle school (or "junior high" as they called it back then) to stay home and watch the second pictures ever from the surface of Mars come back.  Line. by. line.  The first pictures were from Viking 1 which landed a couple weeks earlier, but as that happened before school started during the summer break and I didn't get the day off from school I don't count it.  :D 
     

  5. I've been "working" on my computer today, just cleaning up and doing some file maintenance.  Found some *OLD* text files from an online game called Dragon's Gate.  DGate was a text-only multiplayer game hosted by GE's "GEnie" online service back in the early 90s.  Pre-internet.  Pre-MMORPG.  Dialup-only.  It may have even predated Compuserve and AOL.  One of the files shows a 2400 baud connection at the beginning.  :D  I think this may have been the first multiplayer online game I ever played. 

    Not for long though.  Long distance phone calls cost around $0.25/minute so playing for an hour was like $15.  This back when gas was like $1/gallon so that'd be around $50/hr at today's prices.  I knew a trick to call through a chain of "local" BBSs to pay about 1/4th that, but it was still expensive.  Especially for a lowly student whose only regular income was a monthly allowance!

      I remember watching my friend play Dragon Realms, same type of setup... I was soooo jealous 😁

  6. OMG, the hype for KSP2.  Have to admit I'm catching the fever too.  Hearing all the right things from Star.Theory.  I just hope they can deliver (somewhat) on time & w/out screwing it up.

  7. Sooo hungry.  And hot.  Needed to run a bunch of errands this weekend so I ran out the door early w/out breakfast, then the place I picked for lunch was too crowded so I just skipped it.  Between that and the 107F temp... finally done and home but 🥵, 😫, and need 🍲    Think I'm just going to hide here in the air conditioning and eat 2 sandwiches.  :D  

    On the plus side I did manage to take care of all my errands so tomorrow is clear.  Maybe some anime?  Games?  Reading?  🤔

    In case you're wondering, this is a "tinybopper" from a microgame called "RIVETS" that was released in the mid-late '70s.  I bought them all as they came out, and still have most of them.  Er.. somewhere.  :)

  9. Trying out a new avatar pic.  I'm thinking I like the old Taurus better, but I'll keep Hachirota for a week or so.

      Once upon a time there was a guy in the local mall who did walk-in portraits/caricatures.  He was good, but kind of expensive.  Enough so I that I never did it, but I always thought that would be the best avatar.  If he was still there it'd be fun to see what he could come up with if asked for something anime-ish.

  10. Contemplating an upgrade/refurbishment of the solar-powered lighting on the "back forty".  (This is Los Angeles so that's in square centimeters.)  There's no AC run out there so a number of years ago I installed a solar panel, battery, charge controller, and motion-controlled LED lighting system.  It has been working pretty well, but it is showing its age.  The battery is/was lead-acid (basically a motorcycle battery) and needs replacing and the LEDs were pretty dim from the get-go.  That's what was available at the time so I'm not complaining, but these days it could be done better.  I can reuse the panel and (maybe) charge controller, but I'm thinking a new, custom-built LiFePo battery (built out of 18650s or 26650s) and some modern, bright LEDs are definitely in order.  Maybe even some RGB lighting if I want to get fancy.

  11. Einstein, Newton, and Pascal are playing hide and seek. It’s Einstein’s turn to count so he covers his eyes and starts counting to 10. Pascal runs off and hides. Newton draws a one meter by one meter square on the ground in front of Einstein and stands in the middle of it. Einstein reaches 10 and uncovers his eyes. He sees Newton immediately and exclaims, “Newton! I found you! You’re it!”

    Newton smiles and replies, “No, you found a Newton over a square meter. You found a Pascal!”

    (This is the kind of thing I have to put up with at work. The offending party has been dealt with. 1f642.png )

  12. They delivered the two new widescreen HD monitors and stacked them outside my office, but they didn't deliver the computer they're supposed to be attached to. That's just cruel.  :angry:

  14. Shift over at 11pm then home to sup, sh!t, shower, and shave to get back to work by 7am for another full shift. Getting too old for this kind of thing.

      I don't miss those back-to-back shifts, they're just cruel. Hope you can get at least a little bit of rest! I remember you did say you were expecting a busy summer- with any luck things will come back around and normalise for you?

  16. Found out I "get" to work 2 extra days this week.  Joy.   😿 

    At least that means my weekends are back in sync with the rest of the world's.

      Lol...at least it's only 2 days and not practically the whole month. Been crazy here, like some kid kicked over our anthill and we're scrambling all over the place trying to put it back up again. I'm so tired. 

       

      Enjoy the weekends :) are you having to meet a deadline or did something else come up at work?

    2. efaardvark

      Kind of a combination of factors here.  Higher than average workload this year with chandryaan-2 launch and testing/training for them plus a bunch of cubes going up on the one hand.  On the other, in the last several months we've also lost 2 workers.  3 actually, one retired, one got fired, and then one of the replacements didn't work out & we had to start over.  We're a 2-position, 24/7 operation so losing two out of 8 people .. we're feeling it.  2019 has not been a good year so far.

      I talked to my boss today & he says he's hired a replacement for the replacement so there's light at the end of the tunnel.  However, even best case it'll take a couple weeks for badging, background check, and other bureaucrazy before he can even start training for the actual job, and another couple/few months after that before he's pulling his weight.

      I've been there too. We lost 5 of 9 once and it all fell apart. Right now, we did this to ourselves buying up more business than we can handle so I'm just trying to help cover shifts, give some overlap to help catch up and ending up working nearly every day. 

       

      I hope the new guy works out for you.

      @Wedgy Actually, now that you mention it I think I did see that movie.  It didn't turn out well for the humans.  :)

      @Nono Not kawaii at all!  :D  

  18. Well, looks like Chandrayaan-2 launched successfully.  Launches are fun to watch, but the DSN's job doesn't really start until they actually deploy and we start getting data on the ground, and the first few tracks after launch are apt to be .. interesting until the critical spacecraft checkout is done and things settle into a routine.  

     At least it is a swing shift schedule for me so I got to sleep in.  My boss had to be there at 2am for the launch.  :D  OTOH, I'm once again batting cleanup so I get to deal with any issues not caught in pre-launch testing that crop up.

  19. Thank you, USPS.  😠

      I think my two cents might actually be relevant here 😂 My comment in one sentence would be that we are not even close to being ready to actually implement something like this in any reliable way.

      As it happens I both studied and now work in a closely-related field (although my focus has changed from empirical to theoretical/philosophical). I was quite enthusiastic in the beginning, but I can say with quite a high level of confidence afters spending some years in that field that we don't understand the brain. We have accumulated a lot of both empirical data and models, and we do know a lot more then just 100 or even 10 years ago. But we are far from knowing how the brain works when it comes to any function that is a bit more complex than simple neural networks or even action potentials (even those are very tricky if they deviate from the prototypical neurons usually studied).
      When it comes to BMI specifically, there is some interesting stuff going on right now. One of the research groups at my university is working in a particular field regarding BMI which got me interested in it, and we even established a new research group dealing with philosophical problems related to it (although I would not say that I have much expertise when it comes to the technical aspect of BMI). What Neurolink is showing here is promising in achieving the goal of activating certain sets of neurons but their possible application (at least as presented here) a bit oversimplifying how certain functions are represented in the brain (especially when it comes to localization). The basic idea is not new, but how they are implementing ('wireless chips') is something that has been notoriously difficult (but has been researched for quite a few years).

      When you take these aspects together, I think even if we successfully implanted even much more complex devices, we are still far from knowing how to use them in order to achieve something we want ("to tap into those representations") in any reliable way (meaning without serious dysfunction or non-functions). This can be used for research which might one day enable a much more successful implementation of course, but we should be realistic as to the actual mid-term achievements we can expect from it, given the current state of knowledge. This is disregarding the huge ethical issues concerning malfunctions and risks.

      So yeah, interesting stuff but as it often is with publications or innovations, the actual immediate usefulness is still quite 'hypothetical'.

    2. efaardvark

      efaardvark

      I totally agree that we don't understand the brain.  It has had literally hundreds of millions of years to evolve, and genetic algorithms are notorious for producing idiosyncratic designs.  I'm reminded of one research project that used a large chip with an array of identical circuits that was used to develop some software using a "genetic" process to evolve the software.  Each bit of software was slightly modified/mutated and assigned one of the array elements to use, then evaluated against the software design criteria.  Evolve, repeat.  It worked extremely well, with the best software being roughly 5x as good as the software developed using more conventional means.  Then they tried to figure out why.  Turns out that the "evolved" software had figured out that the supposedly identical and independent hardware cells were NOT compeletly independent and was actually using the undocumented interaction between cells to achieve its results.  :)

      So yeah, there have been and will be moments of confusion and misunderstanding on a science and engineering level.  Politics and public sentiment will no doubt also play a big role beyond that.  (Though both will be decades behind in actual understanding that's never really mattered before.)  That said, there is progress being made as well.  I view this as basic research.  There are goals, and the researchers know enough to think and expect those goals are attainable.  I tend to agree, but there's a HUGE grey area (no pun intended) that they need to navigate through before they get where they want to go, and plenty of opportunity for things like frustration, serendipity, and even tragedy along the way.  It will not be easy or quick.  It will definitely be interesting, and very likely extremely useful, though perhaps not exactly in the way(s) expected at this point. 

      I do think that the gross motor areas they are targeting now is a good first step.  They're not trying to put anything INTO the brain, just read the motor signals that the brain is outputting.  That's ambitious enough, but also limited enough, that they can make progress towards their goals in a reasonable time frame, and if they reach those then they'll be in a good position to move on from there.  Clearly though Musk is thinking beyond that however.  "Having the option to merge with AI is important."   😮 

    3. Illusion of Terra

      Illusion of Terra

      the grey area pun was hilarious 😂

      I totally agree. And I think targeting something like the motor cortex is a pretty reasonable starting point since it at least seems to be less complex than, say, the hippocampus (or at least the parts they are investigating).
      This reminds me of people who lack substantial parts of their brain but show little to no impairment. A senior neuroscientists in our department told us of a case from someone who literally lacked most of what we consider to be a full brain but showed almost no symptoms. Such cases make brain science quite difficult because of the huge flexibility it portrays. But this is not to disregard the huge advancements, both in research and treatment, made in the last decades.

      Merging with AI, at least what people would usually understand, is however something I don't think will happen in our lifetime. Would be extremely interesting though to see what kind of effects it would have.

  21. A Joule is a measure of work energy. It is about equal to the kinetic energy of an apple dropped from a height of 1 meter as it hits the ground. A human being radiates about 60 joules per second of heat energy.

    A Joule is equivalent to 1 watt for 1 second, or a watt-second. A watt-second uses the same units as the kilowatt-hours on your electricity bill, and the power company could just as easily bill you in Joules as in kWh. If you use 1 kWh then you've used enough energy to light a 100W lightbulb for about 10 hours, or about 3.6 million Joules, or enough to get my car about 3.3 miles down the road.

    Yes, it has been a slow shift, now that you mention it.  :D

  22. They delivered lunch to us operations folks here supporting the Chandrayaan-2 launch. However, as it turns out the launch itself was scrubbed due to technical difficulties. The schedule was pretty much cleared for the launch so there's really nothing to do for the rest of the shift, but plenty of grub. Best possible outcome IMHO.  :D

      I could probably work from home.  All our monitor and control tools are unix-based, and I'm running Linux at home.  It Is a simple matter to log in and redirect the display(s) to my desktop's display server.  I've done it before, even over my glacial (1.2Mbps) DSL.  The voice nets might be a bit tricky, but everything is VOIP these days.  There's probably a software solution out there somewhere for that as well.

      However, just because you /can/ do something doesn't mean you should. ;)
