Solar is much cheaper and wind was already cheap, however the question, for both carbon and cost, is what is the price of the renewable intermittents with storage and backup. Batteries and storage in general have not had the step changes in cost and performance that solar has. Backup tends to be fossil plants. Ultimately energy density is a zero sum game for the environment and cost. In more detail:

On storage:
Rough calculations show, if there were just enough Powerwalls to backup US peak demand for one hour it would require 10x the global annual mining production of lithium. And that's just one hour. And that doesn't include the electricity production.

On panel material required for production:
It's generally estimated that US power, with good transmission, would require enough solar panels to cover the entire state of Massachusetts. Most non solar advocates think it's this square footage that's important. But of course this can largely be put on built land or in deserts so that is a relatively moot point. In fact, I want to get solar panels on my roof. However the real concern is what does this look like in terms of material mining? In immense panel production factories? (which isn't the greenest mfg process ever, likely one of the reasons it is largely done in China)

On mining and transporting material required:
Mining is almost entirely powered by fossils, it has to be. And so is most transport. And so is recycling of metals. So the energy density of an energy source really is a zero sum game. If it takes a millionth the material for one source versus the other, that adds up.

On maintenance
Then in maintenance, solar farms are truly "farms"- they require a lot of water to wash away dust to operate optimally. A states' worth of water is significant.

On lifetime/end of life
First of all the lifetime of a panel is very optimistically 30 years/for a nuclear plant 60-80 years, and for the UPower fuel in particular can be used and recycled repeatedly for about 70+ years.

afterlife/recycling
Then in recycling at end of life, and this is why I got so excited about nuclear as a somewhat hippie child growing up around oil companies in Oklahoma, solar is going to require a lot of energy (and fossil fuels or nuclear) to recycle, while nuclear can produce energy in recycling its fuel.

The main import, to me, is: what is the energy density of this energy, and if emitting, how much pollution? Coal is far more energy dense than wind, which is why humans evolved from windmills and wood to coal. But it's so polluting which is why we are all working towards better sources, and the greater energy density (nuclear on order of 2M x any other source) that's roughly 2M less trucks transporting, 2M less mining to do, 2M less recycling, etc. Thats more on the environment than pure cost like you are saying but the costs add up if the full life cycle is taken into account on both sides.
I'm pretty sure it does according to this wikipage[0]. It may not load _all_ the rules into every page, but it definitely does create a stylesheet and inject it into the page.

I guess we'd be stuck with Make. I can't say how happy I am that that isn't the case.
I personally think that creating laws to prevent government surveillance is a pointless endeavor. The NSA has ignored and broken laws in the past, why would we expect them to follow new ones that are passed?

The only way to prevent surveillance is with a technical solution (encryption), not a legal solution (more laws).
It seems that the vast majority of these open-source TSDBs are focused on fairly technical event stream data arising specifically from IT infrastructure... is anyone using them with success in more business-oriented domains, e.g. energy meter data, stock trading, other telemetry?

I can finally go back to ABP!

Firefox used to crash a lot, and freeze a lot back when I was using ABP.
ublock has never worked as well for me, I also dislike the element selector. Sometimes I want more than blocked something being displayed, like blocking a script. And ABP allowed that easier, that's something I miss.
I'm connecting fine to us-east.
Fastmail web interface users + ABP|ABE|uBlock users:

When I have any of these three blockers installed, and then use mail composition on the Fastmail tab, the page jumps around while I type. Eventually the line that I'm typing has scrolled itself down to the bottom of the window, and sometimes even jumps between below the window and just enough above the bottom.

Anyone seen that?
I would have hoped that as web devs we would have learned our lessons from the IE6 fiasco. The only browser web devs should be supporting and evangelizing is Firefox. Admittedly Firefox isn't always the best browser, but it has always been good enough, and if the people spending time, money and effort improving WebKit or Blink spent that effort on Gecko and Firefox instead, it would be a better than it is now.

Personally, Firefox has become my only browser on every platform but iOS and it isn't even for ideological reasons but simply when combined with extensions it is the best browser around. Once it (finally!) incorporates isolated processes for tabs, it's gonna be head and shoulders above its competition IMO.
> On the flip-side, joining a consulting firm is like a 10x multiplier on experience. You're constantly updating your resume for clients.

Starting out at an agency was so incredibly valuable for me–the endless train of projects provided a massive boost to my skills and confidence. I started out self taught, basically programming for fun ever since I was a kid, never really considering myself a 'programmer'. My boss (and somewhat of a mentor) basically threw me in the deep end with client projects.

I somehow managed to actually do well on my first project, and wound up getting to tackle some of the more ambitious projects we'd land, eventually participating earlier and earlier in the planning process and having more influence in how things were done. It was such great all-around experience. Now I work at a startup (and quite a fast moving one at that), which is great, but I've realized that it would take me so much longer to get to the same level if I'd started out in a single-focus type of company rather than an agency/consultancy taking on all sorts of different projects.
What do you like about the JS build systems more?
As someone from the target audience of this document I find it really helpful and descriptive. I was looking for such a resource for ages.

Also keep in mind, that the whole thing is created maybe yesterday, so it's ok if it's not perfect yet.

Safari's new approach of using a built in (natively compiled) rules engine to block content seems more and more to be the best option. But it's also the kind of option you'd only see from a vendor who doesn't make any money from ads (Apple... and possibly MS).
Poorly worded on my part. By "actual" Court, I meant a court whose personnel are appointed pursuant to the appointments clause of the US Constitution.

Sure, they're all created by congress, but the District and Circuit courts have clear, long-established, transparent mechanisms for figuring out who is on the court.
Should we so easily accept that premise? Sure, we must guard against an erosion of rights. But, it seems that in some cases, we are guarding against subversion of the very tools emplaced to aid us in that objective.
Yeah, it's really oddly worded. Whether or not the 2nd Circuit is binding on FISC is not at issue. The question is whether or not the 2nd Circuit is binding on the NSA (or at least NSA activities within its geographical jurisdiction).
I can't see where on that page it talks about using style sheets. Last week I searched the µBlock sources for use of the nsIStyleSheetService, which is Gecko's internal interface for adding style sheets without manipulating individual documents, and the only use of that interface is for adding css/legacy-toolbar-button.css, which I assume is for some UI.
Thing is, the agency is probably billing the client at least double your rate. If they can string you along without a raise, all the more free money for them.
I agree, with a caveat:

The encryption game is rigged since the NSA and other government actors are able to use public funds to sabotage it. So the legal angle is still important.
Yeah, masks everything with spicy flavours. It doesn't matter the tastes of a potato ...

Fastmail user here. Firefox + ABE + EFF Privacy Badger, no problem.

Fastmail's web interface doesn't even have any blockable items once you log in.
This is good but do not use Adblock Plus. Use µBlock. Adblock Plus let's through some 'kosher' ads. If that's acceptable to you, all good. If you want no ads whatsoever, use µBlock.

It works out of the box and blocks everything. Uses even less resources that any other alternative.

Some AWS specific functions, particularly for newer products or options, aren't always there immediately so you end up having to use boto in those cases. You also sometimes use provider specific options on functions, so it's not totally write-once and ignore.
I think I came around to that realization when he starts comparing Postgres to HTML tables.
I keep wondering just how far off "olde fashioned" microwave cuisine is.
They already teleported information via similar means, so I would hope this doesn't mean FTL communication is impossible.
Additionally, it's provable that in the context of a physical computer, no data structure actually has O(1) read / write / anything performance over an arbitrary amount of data.

Consider that the universe enforces both a maximum information density per cubic meter, and a maximum speed at accessing a given physical location.
We're using ElasticSearch for events, too. The aggregation operators are really surprisingly fast.

That said, one major downside to ES is that it's not schemaless. You can try to use the dynamic mapping system, but it will most likely just bite you eventually, since ES is strict about coercing data types. If your data isn't completely consistent, it will actually refuse to index it. Any changes made to your schema also requires reindexing. (For some reason ES can't do in-place indexing, despite supporting storing all the original data in the "_source" field.)

If your data isn't perfectly consistent, one way to work around the mapping problem is to append a type name to every field. So instead of indexing {"user_id": "3"}, you index {"user_id.string": "3"}. This means that if you get some input data where the user_id is an int, it doesn't conflict because it will stored in "user_id.int". You have to handle the inconsistency on the query end, but it's possibly better than micromanaging the index.

Grunt is as elegant as a penguin on land, and about as fast. My gulpfile is a fraction of the size of my gruntfile, and executes much quicker. Gulp has some control flow edges, and requires some workarounds that can make it tedious to maintain when you get into edge cases. Broccoli is ideal, but too difficult for all my team member to understand (and was still a tad flakey when I last used it).

I like to play with new ideas, and some of them don't end up hitting critical mass, but I appreciate their creation all the same. Often, they cause me to reconsider approaches I've taken on other projects.

I'm starting a new project tonight and will give this a go. It may not work, and all I've lost is a few hours. Creation for creation sake is what we should be about. Not everything should be about differentiators, and productivity gains. Sometimes, it's far more rewarding to just create, or to use someone else's creation. Almost every painting I have ever seen did nothing to differentiate itself in style, but I'm glad every single last one of them was painted.
That's my prediction as well, but I wouldn't have put it so....abrasively.
(1) Point me towards the studies that prove SSRI's are so much better than placebo in the sickest patients. I really want to change my mind, but when I read the literature-- it's almost like they just can't admit they were fooled? Plus--take away tri, and hetro-cyclic drugs--the arsenal of cures goes way down, along with patient count? There's a strong reason to protect anti-depressants?

(2) "Eli Lilly, the company behind Prozac, originally saw an entirely different future for its new drug. It was first tested as a treatment for high blood pressure, which worked in some animals but not in humans. Plan B was as an anti-obesity agent, but this didn't hold up either. When tested on psychotic patients and those hospitalised with depression, LY110141 - by now named Fluoxetine - had no obvious benefit, with a number of patients getting worse. Finally, Eli Lilly tested it on mild depressives. Five recruits tried it; all five cheered up. By 1999, it was providing Eli Lilly with more than 25 per cent of its $10bn revenue."

That seems very short-sighted. With (what appeared at the time as) a looming epidemic, what made them so confident that conditions at the sanatorium would be maintained in the future?
Also the FISA court has been called an "almost parallel supreme court" by the New York Times, and given that it only hears one side of a case, makes this all the more troubling.

When I read this I immediately recognized it as a PDF that I have in GoodReader (where I store all my technical PDFs). So I'm curious if it will start a good conversation about b-trees this time :)

To get the conversation started, a couple of years ago, I decided to write a b-tree data structure to refresh my skills a bit. I wrote it in C since I've been doing a lot of Java the last 10 years or so. I only got as far as an in-memory b-tree and had started working on getting it stored to disk before I abandoned the project (think I was working on it during Christmas holidays and the holiday ended).

I subsequently read that in-memory b-trees can actually outperform other tree data structures like rb-trees due to cache coherency. I never bothered to performance test my b-tree vs. an rb-tree I also wrote for fun.

Anyway, that's my story about b-trees!
Anyone surprised that a fake court with no accountability says that the organizations it oversees can do what they want?
I've been having issues all week reaching a lot of different AWS websites including atom.io.

Switching my DNS to 8.8.8.8 fixed it for me. Something is up though.
sounds reasonable. normalization vs denormalization

ok, the last paragraphs kind of give it away... but there are good points in terms of keeping the data flat
it seems like it always is green even when they have issues, perhaps a static page? ;>
We were using InfluxDB for web analytics (generated by user interactions such as "viewed page", "viewed product", "refined search", etc.).

0.8 way okay, but very slow and unstable. But in 0.9 the data model is very different and no longer a good fit for this type of analytics (it looks great for devops metrics, though), so we're abandoning InfluxDB altogether.

We're now in the process of migrating to ElasticSearch, which is looking much better. ElasticSearch has its own problems, though, and we will be evaluating the same dataset in PostgreSQL soon.
Interesting how it took them over 3 months. Mozilla and Google revoked their certs almost immediately

Dark mass, not dark matter
The notions of dark matter and the dark matter particle are incorrect. The mass which fills 'empty' space is beginning to be referred to as the 'dark mass' in order to distinguish it from the baggage associated with dark matter.

'Dark Energy/Dark Mass: The Slient Truth'
https://tienzengong.wordpress.com/2015/04/22/dark-energydark-mass-the-silent-truth/

"That is, all that we are certain about [is] the dark mass, not dark matter, let alone to say about the dark 'particle'."

Particles of matter move through and displace the dark mass, including 'particles' as large as galaxies and galaxy clusters.

The Milky Way moves through and displaces the dark mass.

The Milky Way's halo is the state of displacement of the dark mass.

The Milky Way moves through and curves spacetime.

The Milky Way's halo is curved spacetime.

The state of displacement of the dark mass is curved spacetime.
Gulp 4 is still 'beta'. That trick works with gulp 3 too though.
I have actually heard of Kx and Kdb+ and Q and have looked into those products. You're right that I should have mentioned them, because they are important in that space, and in many ways they are miles ahead. The state of time series query languages is quite poor (outside of Influx's effort), so there is a lot to learn from Kdb+ as well.

I was however focusing on recent Open Source efforts and on the general approaches. Hence, I didn't really discuss in detail my own tsdb.

I also find virtually everything to do with K and Kdb to be be simultaneously impressive and utterly unfathomable:

http://code.kx.com/wsvn/code/kx/kdb%2B/s.k

This is a cheap jab to make, but it makes these systems pretty impenetrable from a source level.
Yet no one has standing to request the Supreme Court look into this. Ah the joys of secret courts.
Nope, people literally did say things like "a certain company in California." But yeah, I'm exaggerating a bit, because the name "Apple" did come up occasionally.

The problem is that when everybody wants to discuss the hot new browser features, mentioning Apple is just a big downer. We all know we're going to have to polyfill at best, or just not support Safari at worst. Nobody wants to be reminded of that sad fact when you're trying to get excited about the potential of the web platform.
> comport with what the applicable statutes authorize

If the statutes are extremely broad and permissive of surveillance, then he could well be telling the truth - FISA could be rigorously scrutinising every request and finding that the statutes permit almost all of them.

A fiber cut in Oregon could be responsible (https://puck.nether.net/pipermail/outages/2015-June/007906.h...). I've been seeing connectivity issues with us-west-2 for most of the day.

Agreed. With the ability to carry out correlation attacks and the proven information content of metadata, encryption can't provide a complete "technological solution."

systemd-timesyncd is not an init daemon, so it's not really a question.
So, this might be a case of me assuming too much, but I basically read every instance of _cosmetic filters_ basically as _css styles_. There are a couple CSS files in the git repository that have "filter" in their names[0], but yeah I can't actually be 100% certain at a glance that they're using CSS and not manipulating the DOM with JS.

I'd imagine it's similar to how Circuit rulings are binding on the IRS. They only have to follow circuit rulings when the taxpayer resides there.
Somewhat off topic, but in the referenced Google blog describing their leap smearing technique, they say that their correction factor is "lie(t) = (1.0 - cos(pi * t / w)) / 2.0" (where w is the length of time over which they are smearing). Does anyone know why they do not just do a linear correction?
this is not for systemd the init daemon, but timesyncd - the optional network time synchronization daemon [1].
The bug is simply filed as part of the overall project.

I use kdb/Q at work and it’s a fun tool to play with so long as someone else is paying for it. It is quite common in finance (and comparably uncommon outside of it). It’s very expensive of course, and the learning curve is hard. In fact, there are plenty of businesses that have sprung up around kdb that offer consultancy services to help you get started. In an unusual maneuver, one of these consulting businesses actually ended up buying majority of Kx Systems, the developer kdb/Q. Anyway, if you know your Q and C++, you will always have a job in finance.

Part of the reason why it’s hard to learn (unless your job depends on it so you are forced to persist) is that the syntax is very terse. Check out this Java API for example: http://kx.com/q/c/kx/c.java. Yes, that’s the actual code you copy-paste into your Eclipse to get started.
