Interesting - will check out Suarez. You're right that doing this in a privacy protecting manner is going to be Hard: by definition it's asking users to disclose their views - although this doesn't have to be to the general public; it could be an opt in thing: eg "Alice wants to subscribe to your reputation data - Yes/No". Storing the reputation data so that it doesn't become a honeypot of metadata is harder however.

There is absolutely the problem that widely trusted people would use their position to push an agenda, deliberately or unintentionally. This is inevitable, as far as I can see, given we are assuming there are no moral absolutes here. So the best we can do is to ensure that users have visibility on the amount and shape of content being filtered out, access to whichever 'authorities' they chose to trust, and make it easy to view the world from different viewpoints.

Fun problems! I can't wait for Matrix to properly focus on it.
OP here.

Use redis if you can. Use something like diskhash if you cannot afford the extra overhead of sqlite/redis.

In my case, the alternative we were using before is an in-memory hash table built at startup from a text-based representation of the data. It was pretty good and worked very well up to millions of entries, but at the current scale we work with, it takes least 10 minutes at startup were necessary to build up the thing and it used ~200GB.
Yep! I Twitched the development live! I only lost the first episode where I wrote the first lines. I'll re-enact it this week (maybe tomorrow) and upload it too and make it a series.

The original idea of McCarthy was to have a list processing language on the IBM 704.

Lisp was always as much as an idea as a real proramming language and both were developed together. Lisp was developed as a practical tool for AI research, especially for his AI research.

Exactly. But DRY does not give you fast github stars nor makes your work sound significantly interesting (I used a perfectly fine but boring 15 year old lib versus I rolled my own). To the Mongo point; investors often want to hear you rolled your own as well. So it will not change soon.

PXL Male Enhancement – Pills to Improve Sexual Prowess?
If you want to strive out male enhancement products but don't need to turn to pharmaceuticals, it might be tremendous to look for some thing all herbal. Luckily, there are a number of natural merchandise available in the marketplace nowadays. Irrespective of which treatment you make a decision to go for, even though, make certain you evaluate all the materials there and ensure you compare the dosages very cautiously while you're at it.

Ask HN: Will I ever find a job?
Hello,
I have graduated for 3 months already. I have a B.S in Computer Science... until now, I just got 2 interviews after sending 180 or more applications and countless cover letters.

Since I could not find a job, I started to work on my personal project and I decided to share with the public:

https://github.com/woguan/Legend-Wings

I am losing my hope to get a job, and I feel like I must find a work not related to computer science.
What do you think of my project? Is it good to show for recruiters?

Owner of Alibaba said he got rejected like 20-30 applications, rejected for applying for Havard, rejected to work at Fast-Food. I am getting close to him? I sent countless applications, cover letters, but I just got 2 interviews... Both of them told me I have no professional experience.

I've spent much of the last year down in the internals of pdfs. I recommend looking inside a PDF to see what's going on. PDF gets a hard time but once you've figured out the basics, it's actually pretty readable.

Some top tips; if you decompress the streams first, you'll get something you can read and edit with a text editor

mutool clean -d -i in.pdf out.pdf

If you hand mess with the PDF, you can run it through mutool again to fix up the object positions.

Text isn't flowed / layed out like HTML. Every glyph is more or less manually positioned.

Text is generally done with subset fonts. As a result characters end up being mapped to \1, \2 etc. So you can't normally just search for strings but you can often - though not always easily find the characters from the Unicode map.
3D (smartphone) LCD displays by light field backlight – RED?
It blows my mind that virtually every major city in the developed world is facing this same problem, yet nobody is doing anything about it.

It's a pretty simple problem with a pretty simple solution. The problem is that local city councils have restricted the freedom to build through excessive zoning laws and regulations in order to increase housing prices for their own private investment benefit.

The solution is to relinquish them of this self-interested tyrant-like overbearing power and set these policies on the national level - basically how Japan does it. The more localized the power, the more self-interest is going to favor a minority of private individuals at the expense of society.
Isn't it more like the artist wrote his text using all kinds of font sizes that require the user to zoom in and out all the time to read it comfortably? Compression would mean that the range of font sizes is compressed so that one zoom level works reasonably well for the whole text.
The guy forgets the main thing here: length, type and range checks!

I'm finding issues like API servers hanging/crashing due to overly long or malformed headers all the time when I work on front-end projects.

Programming in a language with automatic range and type checks does not mean that you can forego vigilance even with the most mundane overflow scenarios: lots of stuff is being handled outside of the "safe" realm or by outside libraries.

Google seems to have built their brand intentionally to be the opposite of what you're asking for though; and absolutely they could be blacklisted with a simple "GMAIL ADDRESSES NO LONGER ACCEPTED HERE".

I'm not sure which one you are saying is security through obscurity here... blah+real.id@gmail.com... or the high entropy mkKAjgsdf788hf87hf@gmail.com, both are obscure, but its a stretch of imagination to start labelling this a security issue.

> Cameras are about to get a lot smaller

No, scientists have developed a prototype which can take fuzzy photos of barcodes.

They then go on to tell you what would be necessary to have their device equal a present day sensor in a phone, but they haven't made one yet.

In fact, no estimate is given for when this technology might be competitive with CMOS sensors. The article just points to his previous work as proof he can get some of his ideas to market.

Relevant XKCD: https://www.xkcd.com/678/

I am excited by advances in camera technology, but this headline is peddling research as a pending disruption to the industry, and I don't see any evidence of that in the article.
No, it still depends how it was mastered. You can have crap sounding vinyl and lossless, too.

> Most PDF files do not look readable in a text editor. Compression, encryption, and embedded images are largely to blame. After removing these three components, one can more easily see that PDF is a human-readable document description language.

Of course, PDF is intentionally so weird: it was a move by Adobe because other companies were getting too good at handling postscript.

Embedding custom compression inside your format is seldom worth it: .ps.gz is usually smaller than pdf.

I don't have an answer for you unfortunately, but this is exactly what I have been feeling too and I am interested in the replies.

It's so difficult. I love building products, I get paid very well, and I have the freedom to work remotely, which has allowed me to travel. I know that I would take a significant pay cut and probably that fear alone of being uncomfortable and struggling is what keeps me plugged in. I feel stupid for being so ungrateful and yet at times I think my computer is killing me.

I honestly daydream of a cabin in a forest somewhere. To stop time.

It might just indicate that Microsoft's recruiters don't talk to each other.
> In other words, it's compression for images.

No, it’s not.

There are two parts to this. First is capturing a HDR image, either by stacking photos or using a sensor with a good dynamic range (and capturing in raw). This is a good thing as you are capturing more information.

The compression you talk about is called tone-mapping and is used to make it possible to view HDR images on a non-HDR display. It can either be (over) done intentionally or it can just be an unfortunate consequence of HDR displays not being mainstream yet. Fortunately HDR is becoming a thing now for TV’s so computers are sure to follow.

Now, viewing HDR material on an actual HDR display, that is something different and can look absolutely stunning.
Google mostly solves this with spam filters instead.
Mighty interesting, sure. Still, I can't stand these awe-driven narratives. The formula is getting old and in the jumping from one wow to the next a lot of the real questions and facts are left half-explained. And as somebody already pointed out, the units... football fields, Hiroshima bombs and the area of California... they should standardize those already, right? Journalists could use abbreviations and the rest of us would get to write unit converters when learning a new programming language.
No, Notepad does one thing but it doesn't do it right. Can't open large files without locking up. Still saves UTF-8 files with a BOM. It can't deal with unix-style newlines.
Windows has NtLockVirtualMemory, but (a) it requires special permissions (meaning random apps can't do it without admin privileges), and (b) something about it feels like it's the wrong way to do it, but I can't pin down what it is exactly.
yes you are right you can have very crappy sounding vinyl, your best bet is vinyl but you always do your research.

I used to trade domains back when I was in college in 2007 (before the market crashed in 2008). It was still wildly lucrative. You could buy a domain for $10k one day and sell it for $30k two days later.

A lot of people had similar stories: they registered Cars.com or some other major domain back in the 90s, sold it for peanuts, and watched with dismay as it was eventually flipped for 7 figures 10 years later.

I know a guy who, on a whim, registered about 100 double-letter domains (AB.com, AC.com, etc.), then let them expire.

Each of those would be worth a minimum of $250k today
12 Powers of High Impact Presenting – Mindful Presenting
I'd suggest you might have more luck with a desktop app. Could wrap your existing web app with Electron or Sciter to avoid needing to rewrite the GUI. Businesses need to know they can rely on the software they use, and that's an easier sell when they can run it on their own hardware. I'd suggest a better business model is a relatively low cost for the software but charge for an optional support subscription.
> I wish my sound system had a "constant loudness" function that I could just engage and put the remote down.

Any half-decent A/V receiver has this option. My Marantz receiver for example can scale the compression automatically depending on volume. The more you turn down the volume, the more it will compress, if you turn it up to max there will be no compression.

Really impressive bridge to drive over. Our bus driver (regular travel bus) stopped on the bridge so people could take pictures. Nobody could tell us why he stopped on the bridge. We figured only afterwards that it is the worlds highest bridge we drove on.
That was a serious question.
No particular insight here, but the bridges and the new roads are all part of the Chinese infrastructure initiative. Besides the new towns being built to replace old ones you also have whole road networks and bridges being built to connect the country.
The area where this bridge is consists of mountain after mountain and driving through theee giants is pretty impressive. Same goes for train routes: also over bridges over mountains, through mountains etc.
If you look left and right there are NO traditional old buildings, even though it is clearly rice and potatoe farmers you are looking at. And they all have new cars. Working the fields by hand but a car they have...

I don't think you can categorize each bridge for its commercial or strategic value. Before it took you X hours to get from location Y to Z now it is less. It's not about connecting two potatoe farmers it is about connecting the county and modernizing its infrastructure.
Right. I could probably rewrite it in about five sentences, plus footnotes ;)
Clearly you're better at driving than me - it takes all my concentration and is very mentally taxing, so I can't afford music in that kind of environment. If everyone did things like obeying the speed limit, and overtaking only on the left, and allowing even a couple of metres more space between cars, it would become orders of magnitude easier. Similarly, the road markings here seem to be quite a bit less clear than in the UK - in terms of how much warning distance you get before something happens (the difference is enough to outweigh the fact that the speed limits in CA are lower), and even just in terms of contrast between the markings and the surrounding environment (e.g. on smaller roads, I've seen lanes marked by uniform light-brown studs in the road, rather than bright white paint). Self-driving cars can't come soon enough! But yeah, if you enjoy driving and/or are good at it, I'm sure driving is fine.

Personal climate control is an unequivocal win for cars, yes.
> nobody can just sit together and cooperate

Doesn't work. If you want fast standardization at all costs, only way to it by forced standardization with "obey or goto gulag" orders send from a "tyrannical government" and "violent" and feared standards enforcement authorities.

When you let people vote standardization takes aaaages. When you let corporations vote, it gets even worse... it may never truly happen because the agreed upon "standards" have purposeful ambiguities sprinkled everywhere 'cause "but that's too hard to implement", and practical implementations never fully obey because "what you gonna do, can't practically sue us for not implementing this". Also standardization favors commoditization, hence doesn't make much business sense to do it if you're the "big guy", and isn't so easy to do if you're the little guy (and you're also eating away your future profits if you're the small guy that knows it's gonna grow bug fast).
How independent is your digital marketer from your tech/UI/data team?
I was reading few articles recently and started wondering how independent are our digital marketers to perform their day to day operations from developers/UX/data analysts?

Below a snippet from VP of Growth at Segment in a recent AMA.

"Pace of experimentation.
We’re not testing nearly as many things as we should. As you pointed yourself a lot of times, one of the key factors to success is the pace of experimentation. So why are we not testing more?
Mostly because we lack technical resources.
I usually manage to get engineers dedicated to Growth, but after landing in the Bay area I discovered that engineers are (surprisingly) a rare thing around here, thus hard to get.
Most of the interesting growth experiments we work on are fairly technical and require some kind of engineering.

Then, the honest answer is internal politics. As most heads of Growth, we’re facing the reality that this role is new and not ingrained in the organizations yet. So we face a lot of pushback from the product/engineering teams when we try to push significant experiments in the product. As a result, we’ve retreated to a safe space, outside of the product, where we can still have a ton of impact but face much less overlap."

With increasing role of marketing across the customer lifecycle and by the introduction of new roles like Head of Customer Lifecycle they need access to every area of the business and product.

Even to run small experiments they rely on developers - there are not enough tools to support digital marketers in those aspects. These aspects pull down the productivity of our DMs.

I would like to know digital marketers/growth hackers views.

What do you guys think of this situation?
Increased trading volume driven by bot-written blogspam produced by the company PR department with the express intent of pumping their share price definitely isn't "better price discovery"
