I've been using a few - in the end I landed on sakura: http://www.pleyades.net/david/projects/sakura

I don't quite remember why I ended up moving from urxvt to sakura (and not eg: roxterm) -- but I think it was a combination of it being light (enough), easy to set up without any kind of window decorations, as well as a sane way to pick and choose fonts. With the current gtk ~/.conf-scheme it has a nice ini-like config file, and I can easily have different font preferences on my laptop, my netbook and my desktop (all different screen sizes and different PPI).

FFW I use a spartan xmonad setup, and typically run one, or a handful of terminal windows, each with their own gnu screen instance (typically one local, and a few remote screen instances over ssh. Sometimes I'll have more than one view/windows to one screen session -- and sometimes I might have a screen for a chroot or local vm/container of some sort).
You'd probably shave much more that $400 by using dedicated servers (rented monthly) rather than EC2 instances.

Example pricing (from OVH):

(You'd probably need to do some homework to find the most price effective platform for your workload. For CPU intensive workload, I usually start with https://www.cpubenchmark.net/ given than OVH gives the exact reference of the CPU they're using).

I was about to ask this on reddit, Tourette is very awkward, borderline difficult, to witness (had a few classmates suffering it) because it's really tense and chaotic, but at the same time the randomness of it make it easily dismissible on the emotional side because it's not necessarily coherent. On the other side, comments that Terry can throw are so logical, they do pop randomly, disrupting his trail of thoughts, but it's far from bursts of slang and F-word, it means something. I can't wrap my head around that.
This includes a year of Prime, which is priced at $99, which makes the math even funnier.
ConEmu works fine with colors. Your ssh client does not...
They do, but of course, it also needs to be generic enough.

But you can optimize their usage in your code.

They probably could save that amount of money by maybe trying different machines/providers.

I wonder what's the annual worldwide cost of parsing XML for example.
I didn't think I put a negative spin on it. I was responding to the other person's rant about 'collectivists'.
I like roxterm, but I recently switched to xfce's terminal, which lets me load it without a menu bar, (I like having more vertical space).

More options are good.

Yeah, I have noticed it improves compression on many of my photos. Why isn't it the default? It probably takes more time / memory to decode.

I haven't looked at the code of this demo but it seems there's no dynamic lighting at all, the "lighting" of the face of each cube depends only on which side it's facing as far as I can tell.

You can see that the underside of trees is pretty luminous for instance.
That was also my first idea about solving it. No idea why they didn't took this route.
I am unable to see any explanation in that article but merely unsubstantiated claims (basically rhetoric). People are disillusioned with democracy and capitalism ? Really ? 1/6th of world's population (India) just had one of the most peaceful election voting in a "minimum government" capitalism oriented leader with unprecedented voter turnout and thumping majority.

Any ways, I will not take even a Noble winning economist seriously if he says he can "explain" global economy. These systems are far too complex. A Computer Scientist with exceptional knowledge about Compilers might be as clueless about machine learning as the next guy. No one can really explain these things. The closest explanations about such things in my opinion is given by either Milton Friedman or Nissim Taleb, and their explantions seem to be that there is no explanation.
Well, thats a problem you can see a lot these days. People just throwing software together without thinking about the efficiency anymore. Because "We'll scale it in the cloud". I'm wondering how much energy and money could be saved by just having efficiency in mind again.

I've used gnome-terminal, sakura and now I'm using terminator: http://gnometerminator.blogspot.co.uk/p/introduction.html

The main difference with the other terminal emulators is that I can easily do horizontal and vertical window splits.

Many use screen or tmux for that but I find them too limiting, especially in their scrollback implementation.
What an odd article - He basically said, "We have a function we call a lot, and so we reduced how often it gets called, and therefore saved money on EC2"

No Details, No how they tracked down the issue, No mention of how they captured the timing. It kind of read like the status reports I send each week to my boss. But lighter.

Aren't the boom and bust cycles more due to central banks, rather than capitalism, itself? I have read it successfully argued that the United States hasn't yet practised true capitalism, but rather forms of mercantilism.
The reason is that the comments would 100% turn into a flame war ("This posting sucks!", "Why are you even looking for software engineers when you haven't raised any money?", "Steath-mode startups which hire are stupid.") I don't think there's another constructive outcome.
The radical promise of the multi-touch interface
I'm not sure in what meaningful sense of the word tmux isn't also a terminal emulator, thus doing more than it should, if I follow your reasoning all right.

" 18 c1.medium (2 cores x 2.5 units) = 3,700 per second"

sounds like bloated js, python, or server side php
Will do, looks cool!
Found the book: How Capitalism Saved America, Thomas J. DiLorenzo, 2005.
I suspect that boom and bust is more fundamental than that. The essential problem seems to be that when there is an opportunity for profit, capitalism very efficiently drives us to exploit said opportunity. In almost all cases, this causes a usage of said opportunity beyond sustainable levels leading to an inevitable bust.
suckless sounds quite like a good name. I'm currently also working on some terminal style I/O and I can totally understand why there are programs with >30k lines of code just for being a terminal emulator. terminal communication is not really standardized. It has grown since a time where "computer" meant a person who calculates things. So I'm not sure it St could arrive at a stable state without also having a few thousands lines more than it would like to have.

But what is wrong with Gnome-Terminal? For me it works well enough out of the box. I literally didn't do anything beside increasing the scroll buffer and haven't run into enough troubles yet to switch.
Just for fun I tried to estimate the performance characteristics of this service.

My initial assumption is that the 2.2M pages per ~18h are the main workload. This is also supported by the chart at the bottom, outside of the 18h timespan there is hardly any baseload. The blog additionally gives the following facts: 18 c1.medium instances and ~60% utilization after the optimization (taken from the chart).

Now this allows us to calculate the time per page. First the time for the total workload per day is num_machines(cpu_time_per_machine)=18machines(18h*0.6)=194h of processing per day.

On page level this is than 194h/2.2M=317ms per page.

This feels really slow, and should even be multiplied by two to get the time per cpu core (the machines have two cpu cores)! I would guess that the underlying architecture is probably either node.js or ruby. Based on these performance characteristics the minimum cost for this kind of analysis per day is $25. For customers this means that on average the value per 1k analyzed pages should be at least $1.13. I think this is only possible with very selective and targeted scraping, given that this only includes extracting raw text/fragments from the webpages and does not include further processing.

Yes, I have forgotten about apps behind pay walls.

As for native apps, good luck with the business if the full code is available and then you have to start fighting against clones that just relabel your work.
Next step would be a laser sintering device (additive metal manufacturing). Floating powder might be a problem, but could be solved with rotating the device to use centripetal force to hold the powder against a surface during the process.

That depends on how stable their server requirements are. EC2 comes into its own when it comes to scalability.

Show HN: 52Metrics,employee feedback application for companies who value people
I have been working on an employee feedback application for over 9 months now, and it is complete. To signup, you need to use the link: www.52metrics.com/signup

My motivation to make it was because it is clear in research that the annual employee survey is broken. And that employees are not able to direct their issues to someone who can help them. The feedback that is taken annually becomes either insufficient or too late. Therefore the management does not get enough time to know and act upon the employee feedback.

In the app, I have divided the variables concerning an employee into four major parameters: management, personal growth, team and company culture. Every week, questions are sent out to the team who can answer one question a week related to any of the four parameters.

The questions are intentionally kept to be open ended, in order to evoke qualitative responses that can be acted upon.

I want to know the feedback from the community if you think this is the right way to go or any ideas that you might have.
Also such controls exist for the CAD/3D market for a long time.

For example 3dconnexion has a 'SpaceNavigator' available for around $120
Fair enough, in a way, but I'd say you can't launch it stand-alone inside an X session without using another terminal emulator (st, xtrem, whatever).
I did see one at the Houston Museum of Art, was very large, (to my eyes) uniformly brown except for a roller-wide of slight other-color brown. I also went to the chapel in Houston. It was all black (vertically rolled) with a black (horizontally rolled) swath on the bottom in a dim, concrete building. I didn't like the feelings of dark, gloomy, and depression they evoked; not really what the word "chapel" inspires in my mind.

I'm not really a modern art fan, but I'll try to keep an open mind next time I see some. Scale, texture, subtlety, I'll keep that in mind. (Certainly the scale is impressive!)

New social music app to find friends, find music
Hi Guys,
we are glad to host a giveaway for you. Our great new social music app-Duorey(www.duorey.com) will be launch in couple of days. Now we host a giveaway for all of you who show your attention.

Simple Rules:
1 Visit our webpage（www.duorey.com) and sign up our early invitation for beta test!
2 Test our app and give us feedback (via email)

Easy, right? We will randomly choose 30 participants who join our app beta test to get the offer by Dec,15 (all winners will be listed in the page)

Why Duorey is so great?

We usually get music recommendation via apps and billlbords. we try to introduce a new way to make each of us feel sense of participation.

In duorey, we can create and share playlist with others who have the same interest. Also, others can easily subscribe and add songs to same playlist. It is a brand-new concept of music mixed with social contact. You will no longer enjoy music alone and realize what you like can be incredibly hot and popular!

Who need Duorey?

Are you seeking someone who grow up on the band you like? Do you want to share what you like to others? Have no idea where to find songs and want to be recommended some fantastic songs you never heard before? Come to join Duorey!
This problem has been ongoing for two years: the post you linked described their new data center design, which may not even be online yet.

Yeah, I just learned that I should use ConEmu + Putty. At least now, I don't get weird colors and a grey background filling all when I open vim.
But I keep missing having something like Yakuake or Konsole.
OVH isn't really production grade hosting, so it's not quite fair to use them for comparison. On the flipside, SoftLayer has been overpriced for a while now, and the IBM acquisition really didn't help any.

Thankfully, there are a plethora of dedicated server providers out there, which can easily beat Amazon's uptime record while still being considerably more cost effective without going as cheap as OVH.
Most of the time, the average HN reader is not the user of the product. Getting feedback from people who are not your users can often be counterproductive.

If you actually want to give feedback, there's nothing stopping you from actually using the product. Most YC companies (actually, looking at yclist.com, virtually all of them) have some way of getting in touch with them on the site, either via Twitter, Facebook, or e-mail.
Most definitely for larger pieces, but it isn't suited for precision welding applications, or complex structures as selective laser sintering would be.
You are right about Latvia tech start-up community - before 2012 we had only 1 monthly meetup group, and only later TechHub Riga - a co-working space for start-ups was launched, and now it is expanding, and other places are being opened as well. So basically the start-up community is active here for about 3 years.

Thank you for the tips.
Thanks for this comment. I hate how many analyses use PSNR to represent “quality” (especially academic papers; I don’t understand why academic CG/CV people have such a love for nonsense metrics).

I think you’re being a bit too hard on JPEG 2000. If you try compressing images to a very very tiny size, I find that the regular old JPEG encoders I’ve tried produce much more objectionable artifacts than the JPEG 2000 encoders I’ve tried, at the same filesize. I haven’t done any very comprehensive study though; do you have a link to a study showing JPEG 2000 performing worse? What type of images and what level of compression was that? You’re right that the JPEG 2000 encoders and decoders have abysmal performance though, making them impractical in many (or even most) use cases.

The big use case I can think of for JPEG 2000 is archival of very high resolution images where disk space is limited/expensive and encoding/decoding speed doesn’t matter much.

I personally thought Google’s WebP was very underwhelming on all the stuff I threw at it 2–3 years ago when I did some ad-hoc personal tests. Basically pretty similar in filesize vs. subjective quality to regular old JPEGs for the images I tested (and noticeably worse than JPEG 2000 at the same file sizes), except brand new and not supported by anyone but Google.

[But note my little hour of ad-hoc testing based on personal judgments of a small handful of images was certainly far from comprehensive or authoritative, and it was a few years ago, so YMMV.]

Seemed to me like the advantages were more political (i.e. giving Google control and helping push support for their video codec and their fight against MPEG license fees) than technical. And it didn’t help that their publicly published comparisons and marketing material were full of obviously bogus tests. Felt like snake-oil sales.

Have they improved the WebP codec since then, or is there a better analysis somewhere of when WebP is a better choice than JPEG?
Usually bad comments are offset by good comments. I don't see any good comments that could come from talking about YC Job ads.
Advancing Biology with an Open-Source Robot
In an age where our pocket phones take excellent pictures, I can see how representative painting does not do well.

I never said I was expecting representative art. I'm confused by your statement "some of the most renowned art does exactly the opposite [of reproduction]," though. Could you explain it?

I'll freely admit I'm not much of a modern art fan. I'm not sure that colored stripes really clears the bar, even if you make the gigantic (although as another poster said, maybe I need to see them in their intended setting). I feel like just as art is more than simply reproducing a scene, art is also more than just producing a feeling.

I looked up Duchamp, yeah, not a fan :) I think I probably understand the works better than Rothko, though.
I doubt bringing fine metal powder to the ISS is a good idea. Any powder that escapes (and escape it will) will end up everywhere, and can short out electronics. Breathing it in also isn't that healthy.
People tout EC2 scalability all the time, but the reality is it only allows you scale down. You can easily find dedicated servers more powerful than the hardware that EC2 runs on, for vertical scaling, with hardware specifications tailored to your workload to boot. And if your infrastructure needs require horizontal scaling, you may need more flexibility than the generic use cases that the tools Amazon provides or can easily find alternatives for less than the cost of the EC2 premium anyhow.
sounds good！
Smartphones are largely unexplored as a secondary input devices. It can be a input for gestures (zooming, dragging, etc), as an extra place to add custom keys (think macros), custom sliders and other touch-based UI controls, or it can be a notification device ("compilation complete")
Fixing corrupted non-starting PostgreSQL database
But the cache is oblivious to which links the TCP connections are going over (well, except via latency & throughput as the post showed). If I understand what you propose, they need to add more bookkeeping to track what the connection did, instead of just doing pool.insert(conn_fd, time.now()). It sounds like the fix was just swapping the side you evict from, which could have been as little as a one line change.

Without a bit more information I think I am just speculating and don't really know. Their solution doesn't really taste bad to me though.
st uses the Xembed protocol so you can use tabs with it using the "tabbed" utility from the same site (ie. you can embed many st instances into tabbed).

Or just use tmux for "tabs", you'll need something like that anyway for scrollback, etc.
Forgot to mention that, the drone works like a dream!
This one may be larger, though it depends on what one means by "largest". It is certainly more powerful.

Estimating Uncertainty for Massive Data Streams
Look at the impact of mobile phones in rural Africa where they have been transformative. The ability of farmers to know things like the price their produce will fetch at market that day without having to go to the market first should not be underestimated.

HTTPS is a good idea but it really doesn't work for me. I am one of those paranoid people who want full end-to-end SSL without exceptions. HTTPS Everywhere doesn't fill the bill.

This is why the company I work for created PanicMode (https://chrome.google.com/webstore/detail/panic-mode/lamdafc...).

PanicMode is ridiculously simple extension. Once activated, it will swap HTTP for HTTPS without leaking even a single packet. Not even pre-flight requests are spared.

PanicMode is not good for general purpose browsing mainly because 99% of the site break badly, i.e. they do not support SSL at all. That is very telling and sad reality. The way I use it is with profiles. I have a bunch of chrome profiles that I use for different purpose. One of my profiles is just for social browsing - facebook etc. I have another one for company stuff. Those profile have panic mode installed and activated. Because I care about security in those profiles I don't mind if I click on a facebook link and it doesn't open up because at least I know that I am protected against side-channel attacks.

It is a very simple mechanism but works well when used effectively.

How to hire the performing growth hacker your startup needs
That isn't really a problem. The problem is that people never pause and reflect over it once they reach some critical adoption. OPs software might never have been a productive business if he micro optimized some C++ code in pursuit of best possible performance. Make it work, then make it fast if you need to, but only if you need to.
