Cassandra has an append-only log file during operation but unlike a RDBMS it's not just used for transaction replay, so you're half write. Cassandra periodically compacts the log and writes SSTable's to disk, but newer data and tombstones are stored in the log for a while which as you surmised does have a performance hit.
> It has nothing to do with technical necessity, or even expenses of delivering a specific user's service.

Exactly my point. Therefore it's driven by greed, and is an indication of monopoly abuse. To repeat what I said. ISPs already have tired plans for _bandwidth_, and those who are heavier users can pay more for more bandwidth, which has technical necessity behind it. There is completely no need in caps.

See https://www.dslreports.com/shownews/Senator-Wyden-ATT-Merger...

> Your focus on that indicates you have no understanding of the market.

I understand it. The only reason this garbage like caps and violation of Net Neutrality happens is lack of competition, and crooks taking advantage of that fact in the context of insufficient regulations to prevent them.
Factually wrong, it is already happening. It is tied to funding for these projects. Project management are afraid of losing key research members when the funding doesn't come through from the UK. So they exclude UK researchers altogether until things biol over. Problem is, these researches could be years/decades long, and joining in the middle of it is way harder than during planning phase.

How our Squads stay Agile
This reminds me when I once did a spot of consulting for a tobacco and cigarette company. Whilst I felt utterly conflicted, all the staff were pleasant, open and oddly conpletely honest about their situation in Australia.

Basically, tobacco is one of the most regulated, taxed and restricted products in Australia. The government doesn't take kindly to them, no matter who is in power, so they have to be incredibly careful to follow the rules as closely as possible. The company I consulted at decided that as they needed to do it anyway they decided to use that to their advantage and did something interesting: they tried to incorporate the regulations into their process improvement model and leveraged the regulations to, rather ironically, increase their efficiency and expand their market share in an increasingky shrinking overall market.

They used over-regulation to their advantage. I've never seen anyone else do this, and whilst I frankly find what they do deadset evil (hence my conflicted feelings on this job) I could not help but to be impressed by the most innovative response to a frankly impossible situation.
That isn't a very good synopsis. In all his books, he compares a "great" company to its closest, best competitor and look at what they do differently across many industries. That is pretty interesting and can give clues on what makes a company successful. I don't remember ever reading "do these specific things and your company will become successful guaranteed" in his books. I agree most business books are like that, but Jim Collins books are not.
Interesting discovery, however the energy density of such a battery would mean it couldn't ever be used to replace current lithium cells due to weight/space constraints. Might have a niche somewhere if gets to commercialisation stage?

Of course it's great if you're replacing normal cigarettes with it. But why should we pretend it's healthy to do if you weren't smoking to begin with? Nicotine is still highly addictive and causes heart disease. If you're not currently using nicotine, why start?
For sure it's not as dense as NY. But even 3,000 ppl/sq mi is more than enough to provide a bus/rail which drives every 7-15 minutes during rush hour.

It would help a lot if the Caltrain would be improved with more rides and less street crossings. Then there should be more buses bringing people to the Caltrain.
There isn't a drive to own a car, a house or other large purchases

Isn't it more the lack of spare cash for those, especially the large deposits required for housing?

so the concept of paying $200-500/more a month for leasing an apartment isn't as cumbersome as it was for the past generation

I think you underestimate the extent to which people have looked at the mortgage costs and would love to own a house if they could afford to.

To be fair though, Steve basically did it three times, once with Pixar, once with apple computers, and a third time with rejuvenating apple with mobile tech like the ipod and ipad. There has got to be something to it when someone can pull it off repeatedly. I remember Ellison once called it an experiment, you tried Apple without Steve and it failed, you brought Steve back and watched it succeed, that combined with the success of pixar suggests that Steve is either doing something right or he was chosen as tech emissary by God.
Off topic but I've used every touch interface that exists in the consumer market and I'd give my soul for a real keyboard. I'd pay 1200 for a real keyboard with a modern mobile OS. Touch keyboards suck... we've all gotten used to them and better with them but they still suck.

> By assisting India you're paying for their ICBM development

India is now part of MCTR (Missile Control Technology Regime) that limits ICBM development. So that's no longer a valid concern. Also, India has done well without the assistance of the US in space technology and will continue to do so. So if the US doesn't want to assist in technology, it's not going to be a show stopper for India. It will continue to eat at the small satellite launch business.
Not so random. We specialise in HFT trading technology and recruit the best programmers and researchers in the world for specific roles building trading systems, developing strategies using machine learning techniques, supporting big data trading applications, market connectivity and other very interesting aspects in very demanding environments hence why I am posting here.

Is it more likely I developed sensitivity after 2 years, or switched types without realizing it? I liked all the other benefits of vaping.
Nope. Gendering ships has always felt awkward to me.
Exactly. It's not a penalty shoot out. The margin of the majority is tiny. Overall the electorate was broadly split among Leave, Remain and Shrug/Dunno. This is in no way whatsoever a clear mandate to leave given that X% of Leave votes were by voters' own admission a protest, and another Y% seem keen to change their vote having had a taste of the upheaval ahead - where X + Y is likely more than 2.

Personally I don't think it "disrespects" the original vote, or the democratic process, where margins are absolutely razor-thin to feel an "are you sure?" followup is warranted. 70/30 Leave? Sure: a clear consensus, can't really argue. 52/48? Different matter entirely.
Well China and Russia already signed the agreement and they both already have very mature missle technology which I don't honk can be said for India at the moment.

Also I'm not sure how much it matters in this case but India only joined the Missile Technology Control Regime a few months ago whereas Russia signed it a long time ago and China has agreed to abide by the original guidelines and applied for full membership in 2004.
The driver itself is horribly, horribly unstable.

Also. I definitely do not have "the freedom to create my own workflow". No amount of my trying, including digging into window manager, UI toolkits, and application code for KDE, GNOME, or Xfce resulted in my being able to provide consistent keyboard shortcuts across the board. So I wasn't able to get to a point where I could use 30-years of muscle memory and predictability in and across the UX to facilitate my work.

I'm not a noo[n]. I'm a distributed systems engineer and functional programmer.

This "Linux is open source, so it can do anything!" trope is really annoying.
When you say "overpaying", what is that number for you? For context, in 2011, Clorox and other established Bay Area companies paid marketing managers with a few years of relevant experience ~$120,000. Visa is starting fresh Economics grads at $70,000 for marketing roles.

If you're not in that neighborhood, good luck. Startups don't seem to value marketing as much as the big companies, and then they wonder why they need 4 people for one job. Offering under $100K for a Director of Marketing (sadly common in startups) is a joke.

Agreed about identifying the real reasons why, habit wise, startup owners do things the way they do. I am talking psychologically, blind spots. Many of us can only introspect effectively when we're afforded sufficient space to think clearly.

I've been through almost all 7 items that Alex Turnbull lists in the article. In the end we had to lay off our single employee (prematurely hired), close office (prematurely leased) and put in storage most of our furniture. We were forced to reconsider all we did through the new lens of this criteria: is there a paying client?

It was a bitter and, memory wise, a cringe-worthy part of my recent history. I'm in my 40s (started our startup when I was 39 - three years ago) and only really had partial experience doing independent consulting. My experience and practical references have only ever been informed from the perspective of an employee and through the paradigm of that working ethic. This, the employee thinking, was the weakest heritage I took into the startup world. As a technical software developer I am sufficiently competent, but only ever lived in an employee (sheltered) worldview. This was a fatal disposition to take into the world of startup.

I learnt a few things in the months after we restarted (circa 2015 Jan):

1. Startup owners run scared 24/7

2. Fear drives most, if not all, decisions

3. The single most import source of fear is the quitting of a secure job

4. Fear affects your technical abilities

5. Hope is the ointment for the fear

6. Subconscious drive to drown out the fear usually means propping up hope, which is usually accomplished by spending, hiring and "growing" - and by spending time with people or groups considered "safe" (out of your field to give you objective feedback!)

7. Rejection feeds fear and affects momentum of progress. So opportunities are avoided because rejection is more likely than success is.

It takes courage and an endocrine balance that favours decisions made without influence of fear. This can only happen when you lose your blind spots.

They should rip up the train tracks and just do dedicated bus lines on the same routes. The delay between trains (esp Caltrain in late evening) is laughable.

Heck, most of the freeway HOV lanes are full of corporate bus routes during rush hour anyway...

I live in Livermore, and my commute to the South Bay averages about 2 hours each way. It sucks, but I've gotten used to it and you just have to accept it because there's really nothing you can do about it. There are only a few major road arteries, and the public transit options are a total joke--it takes LONGER because you need to drive to the train station, then bike or take a bus from the other train station to your work.

Honestly I have no idea what the solution is. Build more lanes on the highway and more people will choose to commute, quickly using those new lanes up.

Allowing commas on the last list item makes it easier to refactor.

Leading commas just shift the problem around, making the beginning of the list hard to change, instead of the end.
The first strike policy is irrelevant in this context. What matters is capability and parity. If a country develops a nuclear capability that they didn't have before, in his case weapon delivery, this is proliferation. This puts pressure on other states to come to parity with that new capability. In this case that pressure would be likely on Pakistan.
Only tangentially related, but this reminds me of something I've wanted for a while: Are there any languages for relational queries, but with improved syntax (composability, epxression capture, static typing?) and which "compile" down to SQL?

Ideally, I imagine something that looks something like RethinkDB's ReQL, but DSL-ed up a bit beyond what's possible when it's "just" a JS library (eg, a nicer syntax for referencing table and row instead of "r.table('table name').row('row name')" and support for operator literals so you can write ">" instead of ".gt" or similar.).
Ask HN: Build a sure-about-voting-trump? site in 48 hours?
Hi guys,

At our startup in The Netherlands we are worried that Trump might actually win... I would like to ask the HN community whether other people, inside the US but especially outside - want to help push the voting in the right direction. Not that we are such fans about Hillary. Its because we do not want Trump to be in charge of the US. Not even for a month. Not for a day. I ask this to people especially outside the US because as non-US people, I can imagine many feel frustrated that they cannot participate in this election. I do not want to wake up hearing Trump has won and I didn't try anything to prevent it.

My idea was to build a voting decision wizard (something like Typeform), targeted to people that want to vote Trump. To ask them if they are sure and to let them think it through. It should contain a lot of humor to go viral (this election proves again that facts alone wont get us far).

I am not that naive that I think we can change many Trump supporters to vote Hillary. I do think that something like this could push undecided people to vote Hillary AND to push Hillary voters to really use their vote. Nothing is built yet, and I am sure there are many other things that could help us with this mission. If there are other ideas out there, lets hear them! Who is helping!? We need devs, designers, illustrators and many many marketeers to get this viral.

I suggest we need something finished this Sunday. With all the tools to work together remotely I think we can make this work. Even if it wont go viral it can make up for a nice weekend project. Whats your thought?! cheers Flip
Another one to add in is "Buzzword Chasing."

I've been a part of a startup where we were growing our core product at a reasonable rate and having success. But some of our customers kept throwing certain buzzwords at us, "Millennials" being the most oft repeated one. As a result, our founder pivoted hard to a new product targeting that buzzword. The consequences have not been ideal. Another buzzword that is currently threatening to derail us again is "bots."

Buzzwords or trends are something big companies can afford to waste thousands or even millions of dollars chasing aimlessly (often for no real return). A startup cannot. Startups need to have a clear vision of a single product and pursue it relentlessly until they are in the black.

When our customers throw buzzwords at us they aren't expressing a need. Reacting to it as such is often self destructive.

It's easy to predict a war long after it has started. It's like predicting WW II in 1942.

The Syrian war, which we have a heavy hand in - before and after it began, started in 2011. That article was written in 2013. And did you check the bio of the author.

It's easy to predict a war after it has started and when you have inside knowledge and a hand in how the war should proceed and end.
The main problem in the above is the "city" of San Jose. it's low rise and tract housing all the way. It's an agglomerated suburb which calls itself a city. It could easily handle 4 million, if they built the transit infrastructure for it and allowed mid-rises --but no.
We need to encourage clustering/density/jobs in more remote areas where housing is cheaper, instead of downtown SF/SJ/Oakland. Wouldn't that help? Or just result in broader sprawl -- I'm picturing LA.
So in the past, you'd just render your template server-side and send the resulting HTML to the user. Easy peasy.

Then many developers switched to single page applications where users download the template and the javascript code and data to populate it, then render the template client-side.

As Varnish Software points out in this blog post, SPAs often have terrible performance, especially on mobile. What they seem to be suggesting as the fix is a strange hybrid: Your application server continues to serve the unrendered template and data to populate it, your varnish cache renders the template, and the user receives HTML.

That depends on what kind of resources do you have in more abundance or are more willing to invest in those projects... You might have lots of ideas and some spare time but not much money, in that case you'd be better off working on some of those ideas yourself (obviously time is a very limited resource so if it's only you, what you can accomplish is limited by the amount of time you can put into it). Or you might have lots of money and very limited spare time (or maybe you want to use the time for something else, or maybe you want to tackle several projects at once and just managing them all would take all of your time), in that case, if you can spare the money, it would make sense to pursue some of your personal projects with some external help...
I think the issue here is that society sets a taboo on certain views, no matter if they make sense or not.

In a sense we have gone back to believing that the Earth is flat when we deny uncomfortable conclusions based on society's (implicit) pressure.
>There isn't a drive to own a car, a house or other large purchases

It's not that millennials don't want to own these things, it's that they see them as out of reach. It's an uncomfortable economic reality that gets abstracted into "kids these days just want different things" like they're hoarding stockpiles of money and refusing to spend it unless the thing-makers read their minds.

100% on board with this. But I think the "dating a great guy" example is slightly off. In many languages, the masculine plural refers to a group of all men, or a mixed group. Whereas the feminine plural only refers to a group of women. And of course masculine singular refers to male only, and vice versa.

Saying "guys" in English refers to a masculine group or a mixed-gender group historically. Same with Spanish, for example. The suffix -o is masculine and -a is feminine. But -os is plural masculine or mixed gender group, -as is feminine only group.

That's generally just how language works. When I personally speak to any group (or person) I don't use gendered language, but although I like your example, I don't think it holds up to scrutiny.
