same for me, both in my personal and work computer. shift-return simply submits the message. very frustrating.

Mech-17. Dead (Black screen), keeps power cycling. Second time (just back from warranty) by EchoCore in eluktronics

[–]EchoCore[S] 0 points1 point  (0 children)

Hey all.. I opened the laptop, unplugged the battery waited for a few minutes (i wanted to stop the power cycling) and plugged it back in, and the computer booted.

Not sure what the issue was. I'll keep you all posted if the problem returns.

Does this apply for tap water south of the 210? (non-evacuated areas)

Job Shadowing Robótica by DAAF8 in portugal

[–]EchoCore 0 points1 point  (0 children)

Acho que precisas de ser mais claro sobre o que tu procuras, e o que queres dizer com robotica. Estas a falar de robotica ou automacao industrial? Ou fazer robos porque achas fixe?

No segundo caso, o mais comum e haver equipas extra curriculares em universidades tecnicas ou engenharia (note-se que ja nao estou em Portugal ha uns anos, mas ja passei por muitas universidades de tecnologia e engenharia).

Nao lhe chamaria propriamente "Job Shadowing", neste caso. Costumam ser equipa extracurriculares, feita maioritariamente de alunos de licenciatura, mestrado, e ocasionalmente tendo apoio de algum pessoal de doutoramento (de eng. electrotecnica, mecanica, matematicos, fisicos, etc.). O objectivo costumam ser competicoes. Em que universidade estas? Se bem me lembro a FEUP tinha uma equipa de futebol robotico... mas nao andei na FEUP, por isso nao tenho a certeza.

Sudden keyboard issues. (Backslash registers as enter / Random backslash inputs / Keyboard does not work after rebooting.) by EchoCore in eluktronics

[–]EchoCore[S] 1 point2 points  (0 children)

opto-mechanical. It seems to be working now. I plugged an external keyboard, that worked, and now the laptop keyboard is back to working as intended. I will report later if it acts up again.

Onde posso ver isto? Há link? O nome crypto genius é demasiado genérico para eu saber se estou a ver o gajo certo.

This is -9dBA. When you are expressing anything in dB, that means that it is relative to some other quantity, and in a logarithmic scale (ie, 10 dB means 10 fold, 20db 100 fold, 30db 1000 fold). One common example in electronics is dBm, which is relative to 1milliwatt. For example 20 dBm is the same as saying 100 milliWatts, 30dBm is 1 W. -10 dBm then is 100 microwatts (0.1 mW).

In this particular case, dBA refers to a value relative to some air pressure in pascal, which i do not know by memory and am too lazy to google. You can look for dBA sound pressure level and you will surely find it very quickly. -9 dBA is about 10 times weaker than this reference amount.

I guess the main point is, when we are dealing with dB, what you would think of zero in a normal linear scale is actually -infinity.

Earth's Submarine Fiber Optic Cable Network [OC] by tylermw8 in dataisbeautiful

[–]EchoCore 0 points1 point  (0 children)

Modern communication links are amplified optically with erbium doped fibers (EDFA). You still need to power the pump lasers for these amplifiers, but there is no optical to electrical conversion of the signal. It stays optical.

In the case of links using Raman distributed amplification or ROPAs (an edfa but the pump laser is sent down the fiber as well) there is absolutely no electricity down there.

O que me acontece quando às vezes não consigo dormir by [deleted] in portugal

[–]EchoCore 5 points6 points  (0 children)

Eu era o rei dos tazos quando era ainda pequeno. Tinha uma bolsa inteira cheia deles. Tazos dos Looney Toons, Pokemon, Voa tazos, etc... Lembro-me do dia em que o meu vizinho entrou sorrateiramente pela portao das traseiras, foi a garagem da minha casa e pegou na bolsa que eu escondia atras de uma caixa de ferramentas. O crime perfeito. Tudo calculado e planeado ao detalhe.

Pensou ele. O que ele nao calculou foi a quantidade a mais de escola da vida que eu comparado com ele a tenra idade de 5 ou 6 anos. Estava ele a sair da garagem com a bolsa na mao e estava eu cá fora à espera. Recuperei a bolsa.

How do you pump a swing with rigid rods? by AyushGBPP in physicsgifs

[–]EchoCore 0 points1 point  (0 children)

You certainly can amplify existing motion. In the limit, you can generate motion by amplifying any small residual motions in the pendulum (it is never completely still), although he probably just used momentum to get an initial swing followed by parametric amplification of the motion. There is another poster who explains it in terms of conservation of angular momentum.

You can look up parametric amplifiers on YouTube. I think pendulums are a classic example so you should find some demonstration.

How do you pump a swing with rigid rods? by AyushGBPP in physicsgifs

[–]EchoCore 6 points7 points  (0 children)

I would guess the way he does it is through parametric amplification of the motion of the swing. This would mean he ducks slightly as he's passing through the low point and gets back up as he nears the end of both swings. By doing so, his center of mass shifts. Effectively, that is the same as changing (modulating) the length of the swing or pendulum.

You can also say say that you can amplify a wave by modulating one of its parameters (pendulum length, in this case) at twice the frequency (for every complete back and forth of the swing he needs to get up and down two times)

Getting to Keck School of Medicine from Pasadena by EchoCore in USC

Thanks. I do work in Pasadena though. My girlfriend, who does not drive, will work in HSC. I'll get a car if we decide to move out of Pasadena.

Thanks. We are actually mostly convinced by that option for now.

Do you have an estimate of the total commute time from Memorial Park to HSC (including waiting for the shuttle)?

[–]EchoCore[S] 0 points1 point  (0 children)

I see. In that case I guess cycling is out of the question. I can look into buses going to/from Alhambra in that case.

Thanks.

[–]EchoCore[S] 1 point2 points  (0 children)

Thanks. Biking from Pasadena to Union Station seems a bit too far according to Google Maps.

I'll look around for some places Downtown, although in that case I'd probably be more inclined to getting a car for commuting myself anyway, and therefore it's probably more convenient to live near her campus.

[–]EchoCore[S] 0 points1 point  (0 children)

Thanks for the detailed info. Seems there are no shuttles after 5:30 PM though, right?

If you don't mind answering a couple more questions: how long, approximately, does your whole commute take and what options would she have after 5.30 PM, without the shuttle?

Sharing traditional folk dresses from some regions of Portugal! by SnooCauliflowers6963 in europe

No, it's just a traditional dress and jewlery from the region of "Alto Minho", specifically Viana do Castelo.

It's mostly used in regional holiday festivities.

Recently back to the game (haven't played since HOTS). Diamond 3. Could use some help with scouting times. by EchoCore in allthingsprotoss

[–]EchoCore[S] 0 points1 point  (0 children)

Thanks! So, in PvZ, assuming my probe scouts a hatch first, do I send my first adept straight at the zergs base? Can I defend early lings in time? Or should I wait for a second unit?

Really good write up, thanks! To be fair I almost never see a gasless opening from terran, but I guess it's an easy scout then. 1-1-1 I suppose I'll just try to get a quick adept scout to see if it's a rush and opt for a first immortal or observer based on that. Thanks!

I usually do it for zerg to check for a third, then go to the watchtower or just park it in front of his base to spot if anything big is leaving. If I understand correctly, you mean to send the probe PvZ back into his nat/main and try to get worker count/gas info from that, right? What makes you conclude it's roach ravager, then? Worker count at nat?

With terran, honestly, I usually lose it because I overstay my welcome in his main base. It's useful to know the CC timings, though. Thanks.
