No. Cheapo adult bikes are typically 30 to 40 lbs. The difference is that these modern cheapies are built with thickwall aluminum or steel tubing to avoid lawsuits and are burdened with modern accoutrements like shifters and brakes. The 1874 race bikes are penny-farthings with very little framing and likely thinner tubes than cheap steel bikes of today.
In the late 1980s, early 1990s, sub-30 lbs was the reference for a high-quality off-road bike. That'd be aluminum alloy rims, steel frames (cro-mo alloy) and aluminum bars/stems/seat-posts. A principle that applies at all times (1800's, 1900's, 2000's), is that rotational mass is what kills you; Roughly, if you can save 1 lb on the wheels, or 1.5 lbs on the frame, save on the wheels. It's mass that has to be accelerated/decelerated, versus (eg) the frame, which is 'static'.

Edit: qualify "at all times", "late 80s, early 90s"
Given that wheel diameters are given, these were likely penny-farthing models: direct drive, one large wheel, one small, no chain.

How is it that this person was convicted on three gun charges, when two of them were (according to the article) based on nothing but the testimony of a single person? The sentence is absurd even if the gun charges are all true, of course, but this seems like an amazingly lax standard of proof as well.
Something I find really interesting is how VIM takes up a huge chunk of the TILs.

One of my personal quirks is I feel like those terminal-based editors consume an undue amount of time and energy to learn and maintain. This TIL seems to give a bit of extra evidence for that suspicion. Simpler options have been available for years now (e.g., Sublime). In those rare moments when you do need to edit files on a remote server, nano is always available.

"[p]olicies that discourage private-sector investment put at risk the world-class broadband infrastructure American consumers deserve and enjoy today"

They do. We should be discouraging both government and private company monopolies because the end result is higher prices and worse technology.
Even Google's "now" is still a little fuzzy -- their system doesn't so much define "now" as it defines the uncertainty around "now", which you can take advantage of for figuring out ordering. This paragraph (from section 1 of their paper) summarizes it pretty well:

> The key enabler of these properties is a new TrueTime
> API and its implementation. The API directly exposes
> clock uncertainty, and the guarantees on Spanner’s timestamps
> depend on the bounds that the implementation provides.
> If the uncertainty is large, Spanner slows down to
> wait out that uncertainty.

...so really, GPS and atomic clocks aren't for defining "now" they're for providing a keeping the window of uncertainty around "now" to a small value. The value mentioned in the paper for this is "generally less than 10ms", which is pretty good for a large-scale distributed system, but massive in terms of precision timekeeping. It is, after all, an uncertainty that's three orders of magnitude larger than the GPS glitch that started this discussion...

I sent you the gist of it in an email. It's not really that clever, nor something that a typical AA undergrad wouldn't be able to come up with. Hence, I don't put a lot of stock into my own idea.

You were making a great point until They'd walk into the office and immediately start up some useless conversation and they'd just shut the f up.

They both illustrate you suffer from the same condition they are: that neither one of you respects the way the other is. What silence is to you (an me perhaps) social interaction and "pointless chat" is to them. If your productivity went up by them not talking, theirs will go down for the same reason.

It's perhaps not altogether useful to regard c as a speed. Or rather you should redefine your idea of speed. It's a universal constant relating matter to spacetime. Time is a length measurement, and you're already moving at c in that dimension. If you start accelerating then you are trading time velocity for spacial velocity, so as you approach c your movement through time approaches zero.

> does that really mean that space is really so constantly twisting and turning that SOL can't be exceeded?

The speed of light stays the same and both time and space twist and turn around it. It's weird, but having a preferred reference frame would be just as weird. c is a dimensionless constant, and light happens to travel at that speed because it has no rest mass.

Do you have a source for this? At the same time, they used lead acetate to sweeten wine and food, which is way more dangerous. If they made the weaker connection between health and water pipes, they should have been able to connect health and this as well.

Yes, an individual website can't track you throughout the whole web and compile a demographics and interest dosier. Only advertisers have that capability because their Javascript is served up by thousands of websites. But that's the whole conondrum! Advertisers want to track, people do not want to be tracked, thus adblockers.

You don't appreciate office cultures involving alcohol or dog-friendliness, and you roll your eyes and put up with them. Some people do value those things, and they also value having coworkers who value those things, which isn't a surprise because most humans value community (though of course different humans have different ideas about what constitutes community). So when you flat-out lie to your coworkers about your feelings, you're undermining the social fabric, for your pecuniary gain (e.g. because you don't want to be correctly labelled a "bad culture fit", because you like the salary). That deceit is straight-up unethical.

It's also disrespectful to assume that your coworkers don't know what's actually valuable to them. Some people prefer an extra $5k in salary, some people prefer $4k of free meals. Or $6k of free meals that costs the company $3k because of scale. Or whatever. Some people are investing in their long-term growth by deeply immersing themselves in their careers (and perhaps working non-long-term-sustainable hours), and if the company provide some cheap bennies that make that easier to do, so much the better. Yes, the company profits, and no the employee isn't maximizing short-term earnings, but maybe it's still win-win.

If employees really can't afford recreating or adequate living space, then of course that's a problem. I'm skeptical that's a real problem in software, though. And if that problem does exist, btw, then I think the best solution is those employees going and finding careers/lifestyles that fit better.

I want to add that I found this comment particularly startling because most of the comments I most agreed with on this page were also by you, p4wnc6.
You're right. My only point was that in this case the guns are a double whammy, they both caused the ridiculously harsh sentence and then also probably the political reason he's not getting the sentence commuted.

Not just that, but Trump supported marijuana legalization as far back as 1990. That was right around the height of the war on drugs, in between "Just Say No" of the Reagan years and the anti-drug, tough-on-crime propaganda of the Clinton years.

I can't really endorse pretty much anything else Trump says, but it really can't be overstated how rare it was for anyone to be standing up for marijuana legalization (publicly) 25 years ago.
Nassim Taleb taught me that the absence of known danger is not the same as safety.

Welcome to 2016
It is basically an end run around the 2nd amendment. Since the anti-gun lobby cannot outlaw them completely they tack on automatic sentence multipliers for any crime where a gun is found even if the gun was not directly used.
Having a look at the company in question, and the products that they produce. I only got as far as the "Diversity Dashboard" to realize that this organization doesnt actually produce anything.

If you don't produce anything real, then you probably don't need any space to do it in.

Meanwhile, the ranks of the unemployed, the hungry, the homeless, and the disenfranchised continue to grow, as any useful capital that remains in circulation is eaten up by these parasitic sectors of the economy.

Im sure that the country has a bright future ahead, where everyone can make a meaningful contribution - such as serving hot dogs and coffee with a smile, or just helping everybody else establish an impressive social media profile.

The rest of the world will be so grateful that they will continue to purchase our debts, extend additional lines of credit, and provide all the manufactured products, food, and energy that we need (but can no longer produce)
Thanks, I did not know about the SEQUEL acronym.
If each request has a session cookie in the log it's easy to track a user's movements through your site, so you can figure out bounce rate, conversion etc no problem. Things like Piwik have pretty dashboards to generate whatever reports you want from server logs.
I wish world realizes this makes this happen.... I think for manufacturing work and so on it made sense build cities.. now if we make as much as work from home then the villages and towns will keep its face and continue have facilities and will grow. Cities wont be over crowded, less traffic etc.. i think there is value to coming to office and social network and so on but i also it is based habits so once majority works from home (with video etc..) then it will become norm... In countries like India we can easily tap top talent which is actually women(in the schools).
Huh, I've had more problems with other blocklists, but never with google. It certainly can be a pain. We need something simple, maybe sort of like EV SSL certs, to allow more painless establishment of email sending reputation on new IPs and domains.
Ok that is a valid argument against remote work.

I still don't agree. In my experience, the added productivity gains from working in a Peopleware-ideal office, where I could occasionally stop by a colleague's office to ask a question, were not much greater than what could be accomplished through video and chat. The personal "comradery" gains were slim to nil as well.

The negatives are tremendous. Wasting time traveling to the office. Wasting time appearing to work, which is probably 50% of the average office workers day if we're being honest. Having to arrange your life around work instead of the other way around.

If nothing else, I think a fully broken-down cost analysis of your office layout plus the higher cost-of-living expenses built into employee wages when hiring in a big city would convince you that remote is the way. Probably looking at 30-50k per employee savings for hiring remote vs SF, and getting happier, more productive employees.

I've wondered this also. Can you point to case law for this?
I've seen some seemingly authoritative sites[1] suggest that owning a legal copy is a mitigating factor under "Market Effect".

Separately, I've seen some reference to opinions that say that the "Four Factors" are just a starting point, and that other factors (presumably including legal ownership) can also be considered. For example, here[2] Posner says "the four factors are a checklist of things to be considered rather than a formula for decision" and "the factors and purposes are not exhaustive".

The hype about Crypter is misplaced and overall dangerous
at the end of the day I can flip from 'work mode' to 'home mode'.

This is by far the most important decision criterion: the psychological cost.
Not only that, up to the late 20th century many products other than pipes contained lead. Lead paint, leaded gasoline, etc. The jury was out on lead in everyday use until quite recently.

I doubt the poisonous nature of lead was well known when these cities were built.
Then they suffer the concequences of people not going up to them. That, or they want people "to know" that the door closed means they can come in - those who they haven't told will shy away. Its kinda a way of filtering, or they're socially inept.

> Music that is predictable is boring. Or music you've listened to a lot and have learned to predict.

You just haven't learned to pay proper attention. I can listen to the same piece of music over and over and over again and not get bored. I stop usually not because I'm bored of it, but because I've had my fill of that kind of experience at that time. I might return to listening to that piece later. The piece falls into a 'rut' in my head and becomes a platform on which I can have all kinds of related thoughts and experiences.

When I'm of a mind to do so, I might listen to a particular piece of music hundreds of times over the course of a week or two.

Here is an article that describes a similar kind of practice:
