I've been a mentee, and I now mentor.

What I want when I see web sites like this is to see an understanding that mentoring isn't Q&A, and it's not "a chat over coffee".

The most successful mentoring arrangements I've seen have always had a clear agreement between mentor and mentee, a mentorship contract with specific goals and hopes outlined over a specified period of time, and a clear commitment to meet and stay on topic, discussing what needs to be discussed.

Training for mentors is therefore critical, giving a clear guide to them as to what they should and should not do (knowing when not to give advice is important, a mentor shouldn't feel they need to fix someone's life).

For mentees, who generally enter into this from the cold and with little experience... having a good mentor matters. And that is far more about having a person who is able to shape and manage the mentorship process rather than just a specialist in a field.

I would suggest going beyond just match-making, and helping to give online training, advice, and a mentor's forum so that they have a support network... such that you can really offer a strong benefit to mentors, and as a result have such high quality mentors that this becomes a key selling point to the mentees.

It is much harder to find mentors than mentees after all, so building an attractive proposition to those wanting to give time is critical.

PS: As an example of what mentors go through, I've uploaded the notes that were the outcome of the last training session I attended: https://www.dropbox.com/sh/a9c832pvsz2tn4j/zAEgACdZ8_/Mentor... . I think online training for mentors, education for them, would enhance the offering... it becomes clearer to them that they can do it, and will be shown how and have support to do so.
Wow, amazing

As someone who was just about to use Parse, what options are you looking at?
I've complied with a number of US federal requests made to a corporation that sells internet access and hosting. The requests started out as federal subpoenas detailing exact information to retrieve. Then they started to slide to unofficial requests for "everything you have" on the target and finally settled on, "please observe this account and search for anything we can use to get a subpoena." That was 10 years ago. What exactly is the victory here?
Thanks, I'll put it on the reading list.
I couldn't agree more, and to expand: what I've found so far on the path to finding a mentor is that initial contact is simply awkward and too much pressure is put on you in the first five minutes.

Finding someone who you think "yeah, I could totally put my faith in this person to give me advice and not me a jack ass" is pretty hard from a two paragraph introduction and a list of all the jobs they've ever had.

It's a great idea from a site but it could fail under the insurmountable challenge of making people feel comfortable around each other for that initial encounter.

It is really easy to figure things out at the cellular level because you can easily build experiments containing controls and the turn-around time on iterations is fast.

The human body has trillions of cells and even more symbiotic bacteria. We are clueless how the system functions as a whole. We know some simple things (iron and calcium compete for absorption in the intestine), but only the "big" stuff.

Maybe if you eat 20% of your RDA of Vitamin E at every meal, it makes your intestines toxic to a particular strand of gut biota that regulates half your body[1]. The space we know nothing about is huge, and jumping in with a product for the masses with so little respect for that is, IMO, very dangerous.

1. There is evidence that people suffering metabolic syndrome have significantly different gut biota than those who aren't and when "normal" biota is reintroduced, their health improves. My hypothetical is not an impossibility.
I'm also curious as to the demand figures. This and a related story concerning Bolivian lithium cite "demand" and (in the case of Bolivia) enough lithium to provide batteries for 4.8 billion automobiles. Which sounds like a lot.
http://www.treehugger.com/corporate-responsibility/bolivia-h...
http://www.bloomberg.com/apps/news?pid=newsarchive&sid=a...

But the Bloomberg piece does provide some quantification:

"By 2014, the mine will produce 30,000 metric tons of lithium carbonate, more than Rockwood’s mine in Chile, which is the world’s second largest. Bolivian scientists say there are about 95 million tons of lithium under the Uyuni Salt Flat"

So: 95 million tons supplies 4.8 billion automobiles.

Simple division gives us 19.4 kg of lithium per vehicle.

The Tesla Model S battery weighs on the order of 400kg. I'll assume half that weight is lithium. Clearly the Bloomberg piece isn't referring to high-range Tesla-style plug-in electric vehicles (PEVs), of which Bolivia could only supply 475 million batteries. That's enough to satisfy the US, but hardly the world, let alone give everyone in the world, or even one in ten, a PEV, plus LiON-powered smartphone, tablet, and other rechargeable devices.

And the rather more modest Wyoming find at 228,000 tons would be good four roughly 1.14 million vehicles.

The simple truth is that we've been able to rely on fossil fuels for much of the past century to provide a convenient energy storage package that's going to be exceptionally difficult to replace. And we will have to replace it.
"Yes, the client should change their software and infrastructure to better suit your product..."

The person you quoted isn't even a developer as far as I can tell.
It's really not that hard to understand why Facebook "actually" bought Parse. Parse has a great product that developers like to use. Facebook has a platform and that requires making users and developers happy. Buying a product that makes developers happy and making it a part of Facebook's platform is a pretty straightforward strategy.
Instagram's API broken again
Suits tend to be uncomfortable (mainly, they're too hot to wear in the summer, don't fit well if your body size fluctuates), are fragile and easily get damaged or stained or rumpled (eg, you can't casually sit on the grass wearing one) and are expensive and annoying to clean (you can't just toss them in a washer/dryer).

So there's a bimodal equilibrium. If you don't own anything that's dry-clean-only or requires pressing, it is a real pain in the ass to deal with one or two items that are. Whereas I suppose if nearly everything you wear is dry-clean-only, you evolve a very different set of habits such that it doesn't seem like a big deal to take care of a suit.

If you only wear a suit once or twice a year, it's not worth getting it re-tailored to fit you well or getting one perfectly matched for the seasonal weather...so when you DO wear it, you're wearing something that doesn't fit well and is too cold or too hot, which makes you less inclined to wear one often.

Scrum is risky
However we can look at what possible applications of rechargeable batteries are, and how known reserves fit into that picture.

Humans are looking very hard to replace our go-to energy storage media: solid coal and liquid petroleum, both of fossil origin. We'll have to replace them under one of two circumstances: we exhaust them, or we cannot continue to abide the CO2 they produce. We're likely to run into both constraints within the next 20 years, if not already.

And when you start scaling known reserves of known battery component minerals against the task of providing, say, affordable transportation to a large portion of the planet's population, or even that portion which presently owns cars, the math starts falling apart pretty quickly.

Lithium is nice for mobile and transportation applications because it's light and has a high storage density relative to mass. Lead-acid batteries also work, and there's probably enough lead to supply a lot of automobiles, but it's messy and toxic and heavy.

When you start looking to grid-scale storage, even lead, as abundant as it is, comes up short:
http://physics.ucsd.edu/do-the-math/2011/08/nation-sized-bat...

More likely: molten-salt or liquid metal batteries. They're heavy and have lower power densities, but the raw materials are cheap and abundant. Thermal storage (again, molten salt, but used as a heat transfer fluid) and flywheels (very expensive relative to capacity, and having their own engineering challenges) might also see application, the latter having benefits for being able to respond very rapidly to large changes in supply or demand.

So, if battery life is 10 years, and we can recover 93% of the lithium, in 90 years we'll have lost roughly half of it, and in 400 years we'll be left with 5% of our present supply.

That is: we lose half the original amount after 9 recyclings, and 95% in 40. Scale time to exhaust known lithium reserves accordingly in the event battery life is longer or shorter than stated above.
Knowing math and programming is important, knowing finance isn't.

The friends I have who have a degree in mathematical finance say that the finance portion of their degree was quite useless and only very weakly correlated with how 'finance' worked day to day at their job. Basically they learnt everything they had to know about finance on the job. The optimization and statistics they studied on the other hand is stuff they use every day, and if they could go back and do it again they would study less finance and more math at university.
In my experience of the big problems is that it's so hard and inconvenient to call other programs and capture/process or print-to-stdout (as required) its output from WSH (javascript or vbscript). Also, if cscript had been the default WSH handler (rather than wscript), that would've made it much more like batch files. It's in the details - I tried for years to switch to WSH over batch files, but each time it's those little annoying things that make me switch back.
One thing I dont get about maven is why the version number get embedded in the jar's filename. Everything has to be rebuilt when you switch to a new branch that has a different version number, deployed files cant just be "copied over" etc. Seems a huge impediment to any kind of efficient deploy system.

I am not that well versed in build systmes, but I have never seen another build system that does this. Usually version numbers is stored in some meta data not in filenames.

I have to agree with you, but I wonder will it ever be feasible to really understand that in a way that helps individuals? There's an amazing amount of hidden complexity.

For me this experiment is a testament to the variety of human individuality, and the resilience of the human organism.

I can't imagine wanting to replace most of my food with a powder shake, and I drink them fairly regularly post-gym. Beyond that, I think the author's self-testing and self-evaluations are so lost in noise, and so subjective, that they have virtually no measurement value. Finally, his method of picking out what he needs seems ad-hoc and partial.

While we can show lots of things are wrong with chronically bad diets, the human body is surprisingly good at dealing with sub-optimal quantities and qualities of food. The 'perfect' diet is a curious notion really, since the body is a dynamic system that responds to input.
Sometimes it despairs me how awkwardly big news sites phrase things when it comes to things they don't truly understand.

The user will probably not stop browsing, and they'll probably make a new account. But I guess 'quits' sounds so much more extravagant.
If proper studies were done on this, we could actually know if it is better or worse than burgers and pizza. From what I know of how the human body works (serious amateur interest), I'm exceedingly doubtful.

I really believe the combination of long-term liquid diet and an extreme uniformity of diet will be the cause of significant health problems. I also think we will find a bunch of "nanonutrients" that are critical to long-term health that we have no idea are important today.

There is no easy answer today for nutrition. If there was, the thousands of food technicians working everywhere from universities to food companies to NASA and the military would have already come up with it. They all have compelling reasons to try.

Nothing terrible happened at PyCon. The three people directly involved are all fine people.
the strategy of getting a PhD can be quite hit and miss - sometimes trading firms want very specific knowledge, e.g. specialist in solving certain kinds of PDEs, or DSP specialists, or bayesian/uncertainty statisticians. or sometimes they just want somebody who knows how to look at ambiguous problems and ambiguous term sheets and contract specifications and put it into solvable forms so that the already existing megabrains in the team can try to crack it. it really depends on the outfit. if one already has a phd and wants to get out of academia, then finance might be a good option. getting a phd purely to get into quant finance doesn't seem like a positive NPV investment (not just opp cost but also the soul crushing life of grad studies). as it turns out, quant funds also hire a lot of bachs and masters. not everyone needs to be churning out new models, 99% of the work is keeping all the systems and the analytics running and expanding existing knowledge to other markets.

Wow. This reply has only served to illustrate how broken the current system is.

If you are publishing articles with no source code, how is that even science? Why not just skip the articles and publish unsubstantiated assertions? After all, if you publish details of how you worked stuff out, even without source code someone else might reproduce your work.

If the new rule was that you had to publish source then there would still be the same number of jobs in astronomy. I don't seem how _everyone's_ careers could be negatively impacted. And don't you think if you are using the software from another group you would cite the authors?
They don't act differently, its just a dyno separate from the web and other processes.
Huh, subtitles are disabled by default for me and probably for many others (is it on by default for anyone?). It's a bad idea to add external subtitles if you're not actually subtitling! They should probably be embedded in the video.

I still don't get what you do. I know what you promise but not how it works. You should probably focus in setting up a website first and then promoting it.

IMHO the video is totally not worth it: the impression I got is that you're lazy, don't care about design and are tacky at the least.

Remember: you sell when you catch my eye, not my rational mind!

Also: not being concrete about what you do sounds fishy. Everyone promises profit! But how are you actually going to deliver?
Several reasons.

Firstly, it's a boys club up top-- a lot of PhD requirements are build around basically hazing rituals. It's designed to make you "prove" yourself-- instead of remembering the Frats founding members, we memorize moments of inertia and rotation matrices, but it's really the same thing, seeing as how I don't deal with those items on a daily basis at all, and a quick duckduckgo will give you more information than I ever could.

Secondly, astronomy and astrophysics is arguably the least essential of the sciences, so our funding shrinks accordingly when economies crash (what do we really make, coffee books?). We don't make quantum cryptography, and we can't levitate objects... although we have some remarkably military grade trajectory maps for all your satellites...

Thirdly I think it really is an attempt to make us work well past what any other industry would consider remotely acceptable. For a bit of insight into the situation, check this completely serious correspondence sent to an unnamed faculty which is now famous in the astrophysical community: http://jjcharfman.tumblr.com/post/33151387354/a-motivational...

I personally work with a 40 year old doctor, a leader in their field, who has not published a major paper in the last 3 years. They're being deported and are moving back in with their family if they can't get a job in the next month or so after having 2-to-3 3-month "pity" contracts. Of course this is just a hearsay example, not the norm, but it illustrates.

Another thing to remember is that we basically cannot have real families-- our jobs frequently require us to change states or countries at the terminus of our postdocs, and our salaries are on the order of entry position BSc coders 50-80k usually depending on skill. The hotshots in the field get 5-year contracts. At age 30 a 5-year contract is pretty much the best you can possibly do.
