> If you can raise your price without reducing rides (1), your prices are too low to begin with.

Yes (ignoring the possibility of wanting to discourage long-term competition by keeping margins low), from a profit-maximization perspective, but not necessarily a quantity-of-rides maximization as uber claims.

> only incur the wrath of users by raising the price when it rains? That's really poor marketing.

Some would argue that surge pricing is already poor marketing, given the negative reaction people intuitively have to it

> As long as the relationship is positive, surge pricing works.

No, depends on the elasticity of demand. If demand is unit elastic then an increase in price will result in a equivalent decrease in rides. In order for surge pricing to increase the quantity of rides supplied supply has to be more elastic than demand.
Not sure what your budget (power or $) is, but I use this for an almost identical situation:

AMD fanless barbone w/ dual NIC (Jetway $215)

4GB RAM (no ECC) ($38 gskill)

So, $315 and ~15W max. I bet this could serve a small office well. Someone should get this down to $200 with minimal specs (and no video or audio).

It has dual Realtek NICs; it runs pfsense and openVPN well, and you can also run squid and snort if you're into it (I haven't learned how to use them yet, but I plan to).

This is what makes so many people getting "breaking" sensational headlines from partisan blogs so dangerous. It becomes calcified reality for the vast majority of people; most folk are not hygenic with their belief structures.

From a link posted above[1], the Department of Transportation Statistics would seem to disagree with your assertion about ticket prices. Someone simply dismissed it as "misleading," but that wasn't exactly convincing. Especially since as a consumer, I care about the average fare I'm having to pay.

I do think baggage fees are a ripoff, and I don't pay for them. That doesn't mean that I have to like the fact that they've started charging for services that should be a part of normal service (like checking a bag the airplane has to fucking carry anyway). Nor does it mean that I have to believe their claims that it actually benefits me as a consumer to be nickled and dimed for everything I'm worth.

I'm surprised they haven't started charging more for seats that recline. Maybe that will be next.

That's the fight or flight response. We view intellectual questioning of positions we hold as an attack on our person. Our rationality goes out the window, our aggression ramps up, and it becomes impossible to back down. It's the main causative agent for flame wars.
The Samizdat programming language
I wouldn't say the younger generation doesn't have baggage.
As a young man I had a lot of fears I don't have now. I
think the biggest advantage to being young is taking on
risk, besides the obviousness of physical strength, stamina, truly original thought(which seems to evaporate in the end
of your twenties?). So yes, as young man I took on risk;
some out of naviete, some out dump luck, some because I
truly thought it was a good idea. As a poor youth, I realized I couldn't screw up too much/or be too risky. My friends who
had wealthy parents could afford to take on a lot more risk
than me, or my poor friends. There lies the rub--most wealthy kids have so many more opportunities than poor, or
middle class kids. I just can't leave the unseen advantage
wealth brings to a string of people and their spawn. In the
county I grew up in I can count on two hands the kids who
went on to be millionaires. They were all from wealthy families. So yes, the young do supplant the "older one", but they usually had a lot of help. An example is our current Luitentant Governer(you can guess which state). I saw his family pick up one
failure after another, and he just might be president of the
United States one day?

Smallpox is the least of the problems that the tribes faced.

Broken promises and laughing officials are the problems.

If you want to get more advanced knowledge then independent study will be way more efficient use of your time. Masters degree isn't all that advanced (after 8 years of programming you should know much more than a masters degree can provide) and in addition to teaching stuff you might be interested in, there's also a lot of wasted time on things that are not very interesting (in general and/or to you). Not to mention massive cost (you not only have to pay the tuition but also are not being paid
for doing software work).

If you want more recognition, blog about technical topics and create useful open-source projects.

I can tell you that no company ever has contacted me after seeing that I have MS in CS. That's not indicative of anything and after few years of professional experience, you're judged on your past performance and not your degree.

Plenty of companies contacted me offering job interviews after seeing my open source work that I wrote about on my blog.

How facts backfire - Researchers discover a surprising threat to democracy: our brains

"In a series of studies in 2005 and 2006, researchers at the University of Michigan found that when misinformed people, particularly political partisans, were exposed to corrected facts in news stories, they rarely changed their minds. In fact, they often became even more strongly set in their beliefs. Facts, they found, were not curing misinformation. Like an underpowered antibiotic, facts could actually make misinformation even stronger."

The Rise and Fall of FairmountBagel
I did it in one go with the rest of the studies. But I did work at the same time - not sure if I'd do MComp otherwise.

From my experience:

1. With 8 years of experience you're unlikely to learn anything new and interesting. Unless you have only coding-to-a-spec experience with no research and learning involved.

2. With 8 years of experience, I don't think anyone will even look at education field anymore. I didn't when I was doing interviews.

3. You've got 2 very different goals listed: "more advanced knowledge in the field" and "more recognition for my skills". You can easily do the first at any point without the second. EDx, published MIT courses, published research papers, etc. are available to you right now. Are you using them already? The only thing that a degree will give you is someone to talk to in person about those things - this may be a great thing, or not. Depends how you like to learn and who is available at the university you're thinking of.

Personally I had a few years of work experience already by the time of starting MComp and looking back: It was rather boring to spend time on stuff I already knew. It was cool to get really advanced people give you specific papers to read. The final project was painful - I never want to write ~80 pages on anything ever again. I don't think it helped with my hiring either - it was more just the professional network.

These days I try to pick up one EDx course at a time, every once in a while, or do some Rosalind problems to learn new things.

What do you oppose in the Common Core? Sure, they might make it easier to develop widely used standardized tests, but the assessment of the Common Core is not the Common Core. Teaching students to be successful with Common Core mathematics doesn't necessarily mean teaching them to pass tests. But the Common Core does ask students to engage with math at a higher level of thinking than did most of the state standards that preceded it. Common Core is actually pretty well thought out--at least the K-8 portion is.

Designing a curriculum around a set of standards does not have to be "teaching to the test" and a cursory reading of the CCSS makes it clear that the answer to questions like "Why is this important?" or "Why should we do it this way?" should never be "Because the test says so." Students should "construct viable arguments and critique the reasoning of others." How does this kill independent thought?

9 Pros and Cons of “Move Fast and Break Things”
> It is economically sound, but it's not ethical.

In this case on the one hand you have people desperately trying to leave a place, and on the other hand you have drivers sitting at home not wanting to risk their lives for $x/mile.

When Uber jacks up prices, you are creating incentives for those drivers to get out of their homes and start allowing people to desperately leave the places where they don't want to be in.

Highers prices>More drivers>More people leaving the dangerous places

There is nothing ethically wrong with it. I could even argue that the unethical thing would be not to jack up prices, since this would put less cars on the streets and consequently less people would be "rescued".

ProtonMail is a scam, much like Lavabit (although the nature of the scam differs). Lavabit at least had the decency to shut down once they realized their claims were fraudulent, once the government told them how they lied and that they would like to take advantage of those lies please.

They deliver JavaScript to the browser to decrypt messages. While it's true that they don't have access to user messages for as long as they remain honest, that's a profoundly useless property to have. You can just be honest and not try to access messages, which is what Fastmail does. There's no point in handcuffing yourself and holding on to the key.

As soon as a system administrator feels like accessing the messages (either out of curiosity / government order or because an unauthorized user gained administrative control), they can deliver modified JavaScript to the browser that sniffs the password and decrypted content and sends a copy somewhere. This is, very literally, "being able to decrypt data."

The encrypted messages that are sent to non-ProtonMail users require visiting a ProtonMail website to decrypt the message, which has all of the security concerns as above. Furthermore, it's pushing the line of what counts as "email". Fastmail is clearly advertising themselves as an actual email service, where you send content over SMTP and it shows up in the recipient's email client. You can't do that with ProtonMail encrypted messages; the recipient gets a link to the content.

You can build a new protocol that has the properties we'd all want out of a modern messaging system. You might be able to replace email. But it won't _be_ email, and Fastmail is email. If you want Pond, you know where to find it.

neat effect i suppose, but i can't imagine it looking very good in-game. doesnt this go against the whole style of pixel art, being aligned to a grid, low palette colors and keeping the same pixel resolution throughout? i see way too many things that change pixel sizes even through the same sprite. i think this would be better suited to larger svg or even pre-rendered images.
I've seen this anecdotally and it scares the shit out of me that it's been verified statistically. Thanks for sharing.
Defer view logic to CSS whenever possible.
Keep data in the HTML.

Ugg, hate the idea of having logic in my CSS. CSS is for style information. How things should look, not what should be shown. "whenever possible" also rings alarm bells for me. There should be one place for logic.

HTML is also View if you ask me and I like to keep my Model separate from my View.

I dont know what people have against JavaScript. I say write more javaScript and less HTML and CSS.
(5-year Scratch veteran here.)

Even though Blockly (and it's predecessor, "App Inventor") is made by Google (the great and the powerful), I have to say, I would rather be introduced to code by Scratch than by Blockly. Scratch is much simpler-looking, it has a beautiful interface, and (most importantly) it has one of the friendliest communities in case you need help or want to show off a project.
Contrary to media perception, the FI I worked with did put a huge amount of resources into preventing illegal activity. Of course trying to avoid legal trouble doesn't necessarily prevent it.

In my brief and painful experience, FIs genuinely do avoid breaking the law. But they don't mind breaking the spirit of the law by finding a way around it.

Nice try. Performance is a side-effect, efficiency is a feature. Nothing you can find will show MDBM to be 10x faster than LMDB. You must be talking about LevelDB.

Look at the results I posted again, and look at the benchmark code. Tell me that I've made a mistake, that's fine. The thing about open source is there's no reason to BS, anyone can build and run it and see for themselves. LMDB is faster and its data is more compact than MDBM, so you can get more work done using less resources, and you don't have to worry about losing your work for unexpected downtime.

Hashes suck for large volumes of data. That's just the reality of it, plain and simple: Low storage efficiency, memory-intensive, and cache-unfriendly. Whether people like or dislike me personally for saying so doesn't change the facts.

As for uptime - sure, and my PCs have uptimes for hundreds of days too. But I'd be a fool to just take that for granted and not take regular backups. The problem with your 99/100 days math is that you can't actually account for the cost of a crash that way. It might only set you back to 0/100; if you're unlucky it will set you back to -100 or more.

>When a person says we shouldn't send people to space, is that also an implicit claim they know the ROI to be insufficient?

Obviously. My point is that having an opinion either way implies knowing the ROI is greater/less than some cutoff.

>And insufficient against what measure?

According to economic theory, the measure is the ROI of the next best project. But even if you don't subscribe to this theory, I imagine most people implicitly judge projects by some criterion that can be expressed as a cutoff of ROI. E.g. most people don't believe we should be building an interstellar spaceship right now, because the ROI on such a venture would be too low.

>Postulation, iteration and testing, re-iteration, re-testing...

A bit confused here. From what I can see, exploration with robots is the path of iteration, while sending humans is the grand scheme. Do you see things differently? For example, there have been four successful Mars rovers starting in 1997. Each one has been incrementally bigger and better. Furthermore, improvements in computer and robotics hardware will happen regardless of investment by space exploration (I'm assuming improvements in the Mars rovers largely piggypacked on existing robotics technology, experts feel free to correct me), while improvements in human space travel will require specific investment in these technologies.
Does Debate about Social Impact Bonds Need a Shot of Realism?
This is great essay. Few points:

1. The more correct analogy would be training data and machine learned model rather than source code and compiled binary.

2. Lot of people move from book to book, always reading some book at any point in time. This provides great dopamine hit to brain and keeps boredome away. However one need to reflect on what they read to gain any significant "take always". The act of reflecting enforces recall which in turn induces analysis and memory storage. I try to create a book review to formalize my reflection process after I complete a book.

3. These days I also get digital (usually pdf) copies of most books I'm reading. This allows me to use tools like GoodReader to highlight striking statements and make notes of my opinions as I read along. You can sure just use pencil and margin of book :). This habit has rewarded me greatly because it makes me take a pause and think about what I read. I can come back to book anytime and refresh it 10X faster. It's also fun to know what my opinion used to be on some of the things years ago.
NICE is not perfect, but it is not bad at this problem.

Triage is not fun, but even with infinite money it is still necessary, and with finite money it has to be coldly pragmatic.

So NICE has a standard limit of £20,000 per QALY, or up to £30,000 per QALY, if certain extenuating conditions are met.

A QALY being: "A measure of the state of health of a person or group in which the benefits, in terms of length of life, are adjusted to reflect the quality of life. One QALY is equal to 1 year of life in perfect health. QALYs are calculated by estimating the years of life remaining for a patient following a particular treatment or intervention and weighting each year with a quality of life score (on a zero to 1 scale). It is often measured in terms of the person's ability to perform the activities of daily life, freedom from pain and mental disturbance."
I'm positive banks here in Spain were doing illegal stuff. And most likely still are if you ask me.

Just google about the very recent case of Rodrigo Rato and Bankia. That man was our Minister for Economy for 8 years and also head of the FMI for a smaller period. Bankia faked its own accounts prior stock listing at IBEX, among other beautys. It's a comic read if you are into that kind of stuff.

I understand what you ment, it just doesn't apply here. In fact, i think there is a market with reclamations to banks on behalf of clients.
