Well, the article does explicitly say that if you can do this then you don’t have “big data”. Maybe you see TB level processing a lot in your line of work, but most developers never will. Whenever I deal with anything a bit bigger, I break off the smallest section I need to deal with and work with that.

That does require recusing yourself from politics, though. Not unreasonable but if everyone does it the field is abandoned to cranks and exploiters.
6.2% social security drops off after $132,900.

https://www.irs.gov/taxtopics/tc751

50% is a high estimate, good for budgeting though. With property taxes, vehicle registration fees (aka taxes), school fundraising (aka taxes), tolls (also tax), health insurance (a tax if it’s mandatory), and other fees for dealing with government, you get pretty close to 50%.

The only way to beat this is to make a significant portion of your income via capital gains, that’s one big advantage of the real estate business, various loopholes exist to let you minimize taxes (like 1031 exchanges) on increases in your net worth.

Both methods succeed. At that point it's just choosing between plague and cholera.
Funny enough I'm deploying OpenStack right now for us as an internal playground. It's decent - but hell, the learning curve is nasty and the documentation is incomplete. Many things I could only get working after asking on IRC and waiting hours for a reply.

But still, it's better than having to manage KVM by hand and cheaper than buying VMware.

Lua means moon in Portuguese, not Spanish.
One time I met a company who insisted they were sending tens of TB of data per day and would need multi-PB per year storage compressed. Took one look at the data: All json, all GUIDS and bools. If we just pre-parse it, the entire dataset for a year fits in a few 100s GB uncompressed -- literally could fit on a macbook air for most of the year.

The funny thing about "big data" in my experience, is just how small it actually becomes when you start using the right tools. And yet so much energy goes into just getting the wrong tools to do more...
I got one from the same company I got my bike from. I honestly can't recommend it. The parts are cheap and seem pretty off the shelf chinese-made. I expected better. If this thing dies I'll probably go with a more time-tested brand, or roll my own (cheap).
> We couldn't even run our basic Logstash offerings on our OpenStack cluster without them having bizarre performance issues.

I'd really be interested in post-mortems. As long as you're not using SDN/overlay networks/weird plugins for Cinder instead of plain NFS, many components of OpenStack are nothing more but a config generator and deployer for core Linux iptables/bridges/KVM virtualization.

> It could never run anything reliably and they scrapped the entire project and re-purposed all the servers for DC/OS, which was super nice and reliable and every team migrate hundreds of services onto.

We're moving our stuff away from DC/OS as we're sick of the instabilities and especially the UI and configuration changing every release. It's been two and a half years of banana-ware for us.

Unexpectedly for me another thing that is becoming relaxing as I grow older is to use my free time to stay on top of my household's chores.

Still far from perfect at it because procrastination run deep in me, but it's something I'm trying to slowly improve.

* If it's simple transforms, use cli tools.

* If this is data you're using over and over again then load it in the database and then do the cleaning, ELT.

* If it's 2tb of data and under, still use bzip2, get splittable streams and pass it to gnu parallel.

* If it requires massive aggregations or windows, use spark|flink|bleam.

* If you need to repeatedly process the same giant dataset use spark|flink|bleam.

* If the data is highly structured and you mainly need aggregations and filtering on a few columns use columnar DBs.

Much better for those who can arguably restructure their salary as business income (e.g., real estate developers, some contractors), then they only get a 15% tax. Far worse for those who cant make that argument and live in high tax states like NY, CA, and many others.

Having launched a startup, my most memorable goal was not hitting $100k, but hitting $1.00. Getting someone to shell out a penny out of their pocket for something that you created was an incredible motivator. I'd focus on that first dollar that doesn't come from friends, family, or investors.
Idk, it's fuzzy, obviously, and a moving goalpost, but in the end it comes down to this: do I buy/rent a bigger server? Or do I put more engineers to the task of replacing the naive algorithm. The latter is Big Data and usually the case when you run out of RAM, not out of disk. And the first one is an underrated option.
I use an awk interpreter called mawk.[1] This is noticeably faster than gawk or other standard variants.

That's a ridiculous equivalence. It's like saying a government backed army and a guy with a gun are the same because they can both shoot people.
I think I agree on the core idea, but if you extrapolate this into font selection, for example, you would rather pick Comic Sans for more "strategic" and abstract projects? ;)
Spaces, tab and newlines are not a problem.

The fact that there are some standard tools available doesn't mean you are limited to that.

If you have a CSV file with spaces and newlines use cvskit or a small python script importing the relevant library. If you have to parse JSON file you can use jq to pick the relevant fields regardless of how the document is formatted. You can even process binary data as long as the file format is understood by the tool.
Best practice is using a new tool which makes this impossible account wide, so hopefully not!

I think the tldr here is that questions/challenges require significantly less energy than answers for many types of questions; and this is more true the more expertise the answers require.

I think one problem is that expertise have been a bludgeon for a long time and intellectuals have done an awful job of not over reaching their expertise and at sticking to their levels of confidence.

I also think that the once important role of “public intellectuals” and philosophers as critics of everything was an essential role to keeping participants honest. We don’t have this any more.
It's related to Purchasing Power Parity [1] and a good example of that is the Big Mac Index [2]. Basically, even if you adjust for exchange rate, the same amount of currency can buy 2 apples in one country and 4 in another. This should not be possible in a globalized market because of the Law Of One Price [3]. However, that only really applies in the long term, for buyers with perfect information (i.e. full knowledge of all price/quantity options), and for goods that are tradable. Land is not tradable internationally. You can't just move 1000 sq ft. from Argentina to US. Same with labor e.g. people who speak a specific language or perform a specific skill. Add to that local taxes, transportation, and energy costs and you can see why the same apple costs more in a different place.

Gas stations next to each other but divided by a state line in the US have different prices. Taco Bell sells the same burrito for different prices. The same factors apply internationally too, nothing to do with exchange rate.

Hope this was as ELI5 as necessary for HN-level discussion.

> Maybe you see TB level processing a lot in your line of work, but most developers never will.

I doubt this is the case. If you're working on even a medium sized team, you'll see this level of data, whether it's internal server logs, publicly-sourced data, or a variety of other applications. Almost by definition, any company that runs a cluster is probably dealing with TBs of data (otherwise they could probably run it on one machine). I don't know the percentage of developers that deal with this, but I do know that it's pretty common.

It’s possible to bring your own encryption to AWS. You can put an HSM you control on your own infrastructure and keep your keys there. As a step further you can encrypt before sending any data there in the first place, though you’re then operating more critical systems yourself, of course.
You are wasting your time trying to use reason with people who have made up their minds already. I am disgusted at the xenophobia and indoctrination going on in West regarding China. There is a lack of respect for Chinese people and this idea that if you repeat whatever CNN et al. tells you enough times then it must be true.

The thing about parasites is that they have to convince the host that they are not the problem. The military industrial complex in the USA has Hollywood and the news to do this for them. Some doublethink happens and despite all the hard evidence of wrong doing by the 'intelligence agencies' in the West the Chinese tech firms rather than those in the West known to be complicit with snitching are portrayed as the bad guys.

I don't know why China bothers to make so many nice things for us. Or to bail out our financial system when we consume so much.

Despite this vulgar atmosphere of sino-phobia it is important to challenge the pervasive groupthink by wasting time on made up minds by presenting more reasoned arguments. With Hauwei it would destroy their business if it were discovered that they had snitch-code in their products. No snitch-code reporting back to some ogre in the dreaded communist party of China has ever been found but the haters gotta hate even if it makes no sense to do so. None of these China haters would tell their own lousy capitalist rent-seeker governments to go to hell no matter how much domestic spying there is or how many more NATO wars against fabricated enemies happen. These sino-phobes are mice, not men.
It's not, but putting up a moral argument based on "hey, we're SLIGHTLY less evil than China because the scale of same crimes are smaller!" is still a bit wierd.

You can argue many other avenues (like having better quality of life if we stay aligned with US vs. China), but doing moral handwringing about Huawei after Snowden's leaks and failings of current US government is a bit hypocritical.

Investing in stock and bond markets is "giving money to strangers for a promise of a return".
> But if your choice is between being spied on by the US or by China, why would you prefer China?

My only argument here would be that choosing China means we're choosing equipment where everyone involved knows that due diligence must be made to keep spying out and communication channels secured. I feel like this is not done enough when using US equipment and has exposed us to too much risk, considering the increasing hostility of current US government and its also increasing push to leverage spying to attack our companies.

This passage caught my eye :

> Researchers have estimated that sustainable use of biocharring could reduce the global net emissions of carbon dioxide (CO
2), methane, and nitrous oxide by up to 1.8 Pg CO
2-C equivalent (CO
2-Ce) per year (12% of current anthropogenic CO
2-Ce emissions; 1 Pg=1 Gt), and total net emissions over the course of the next century by 130 Pg CO
2-Ce, without endangering food security, habitat, or soil conservation.

It feels like every other week I read about one approach which has the potential to save us from climate change, if scaled correctly. Suberin rich food crops. Autonomous ships that produce artificial clouds. Biochar. Painting things white. Olivine rock weathering. Greening the Sahara. I don't believe any of these solutions alone is going to save the planet, but surely doing several in concert would help

I wouldn't consider either HN or Reddit to be addictive.

I guess it depends on a persons mental state though and if they've anything else going on. Lack of friends in 'real' life etc might lead people to over compensate on platforms like this.

Although it's very brief, they touch this topic in the intro: "OCaml does a great job of clarifying and simplifying the essence of functional programming in a way that other languages that blend functional and imperative programming (like Scala) or take functional programming to the extreme (like Haskell) do not. Having learned OCaml, you'll be well equipped to teach yourself any other functional(-inspired) language."

This course is for teaching students who know how to program but are new to functional paradigm. The way I understand the above is that OCaml is impure, so it's easier to have some parts in imperative style to get unstuck and move forward at first. That may reduce frustration for some students. Then over time, as the functional approach sinks in, you move to a purer style (with sometimes imperative parts, but well encapsulated). Haskell would be more like "let's jump at the deep end of the functional pool" --- which can work for some too.
Saving it. This is what I dreamt of for the ETag header of a list of items in a REST API (when caching each of the items separatly).
I was surprised at how much slower the Jump Point Search variants were than vanilla A-star. I thought it was meant to be an order-of-magnitude optimisation over A-star?

Also, any idea what the 'Trace' algorithm at the bottom is? It seems significantly faster/more efficient than the others but I can't find it in the github repo and the live version of the library is minified.

You're pretty much now relativizing based on scale. When I get locked up and harassed without any kind of due process by an American customs official (because economic ties require me to travel to US), I really don't care what China does. And based on my few last trips, the Americans have been significantly more hostile to me on the border than the Chinese.

It seems that some European countries are already reacting to this needless hostility by slowly realigning themselves to China: https://www.economist.com/briefing/2018/10/04/chinese-invest...

Transcoding CSV to TSV using csvkit has been a life saver for me the last few months due to an old industry's insistence on CSV as an information delivery method. jq has previously been a lifesaver too.

(Clearly you're joking) but this isn't an extrapolation. Lines that make up characters in a font don't have any semantic meaning related to the words. Lines in a graph do have semantic meaning related to the data they represent.

[edit] maybe you could make this argument for a language like Chinese. At least for characters with semantically meaningful radicals.

Ask HN: How do you datamine yourself?
Hello HN!
I was thinking about collecting data about myself and using it to draw conclusions about correlations between my actions, feelings and health.

So far, I was not able to find a good way to track all this data. There seems to be no application I could find that
- I can host myself (this data is very sensitive)
- can track all properties I want via computer / webinterface / mobile app.
- is extensible

Apart from that I was thinking about what kind of data to track. So far I could come up with the following:
- data about health and physical activity like sports, step count, walking distance, weight
- movement profile
- Usage of my digital devices (computer, mobile device): When did I turn it on / off, keystrokes count, display brightness, which apps / websites did I use, meta data about messaging, ...

Most of the data will probably require a lot of effort to track. I would later not only draw conclusions about myself, but could also learn about data science.

I would also be interested if you do something like this and what kind of things you found out!

Thank you! :)
