>"Yet trying to recruit from agencies remains disappointingly difficult given the caliber of talent and training overall."

Source?

I'm an ex-agency guy on my second client-side stint. Having spent a significant portion of my career agency-side, I can say that agencies tend to be low-margin, serviced-based businesses, and that tends to suck for their employees. This is because the easiest lever to pull to improve the bottom line is assigning more work to the same number of people (or fewer).

I learned a massive amount in the agency environment due to my bird's eye view of the industry and best practices across numerous best in class clients. But I can confidently say that being client-side is almost always a better work/life balance, and typically better pay as well. Doubly so if you are at a high-margin, product-based company.

As such, the sales pitch to recruit agency talent is typically quite easy if you are actually offering a competitive salary and have healthy work/life balance at your company. Hell, simply mentioning "competitive salary" and "healthy work/life balance" in the same sentence may be enough to get them salivating.

But overall, I would agree that marketing as a profession tends to get a bad rap out here. There are good marketers and bad, just as in any profession. Unfortunately, given that the barrier to entry into the field is significantly lower than some other professions, it is not uncommon for folks to have encountered really bad marketers.

In my mind, a solid modern-day marketer needs to:

- Be able to model things in Excel in their sleep

- Have strong working knowledge (if not deep technical knowledge) of how data flows between various platforms, the strengths, weaknesses, and limitations of said data, and when to trust your instincts over the data

- Have some technical knowledge or at the very least be able to have an intelligent conversation with the engineers and PMs who are typically responsible for implementing what marketing is asking for

Those are a starting point in my mind. Some might argue there are strong marketers out there who lack these skills. I would argue they may be strong in some areas, but their skills are not current or fully fleshed out.
Ask HN: Best Redis production setup practices
Hi,

I am looking for Best production ready Redis settings. Most of the settings are straight forward in Redis, however what are the recommended settings.

FYI, We use Redis for Cache and not for persisting any critical information.
No, but those comfused would be people who haven't worked with plotting and charts and so don't know what "legend" means in this context.
Problem #1: They started in California. Bad move. California is the absolute worst state to start a business in. It's the perfect example of a liberal "utopia."
"People don't want to let just anyone into their home to clean."

And they want the same person each time whereas with drivers that doesn't matter, certainly not as much.

So one way that cleaning companies differ, and I employ cleaners for both my home and commercial properties, is that the cleaning is predictable in nature "every week, every two weeks, 3 times per month" and so on usually at a set time. [1] The only variable is the day that you "setup" with them. Rides don't follow the same pattern. With rides (also much simpler getting someone to the airport) you don't need the same driver and the time is typically not the same and nowhere near as frequent for the average user. With cleaning companies you want the same crew even in the sense that they get to know the lay of the land at your property (home or commercial). (Helps with pets as well). A host of differences.

[1] And once this time comes up it normally doesn't change and you are on autopilot.
I'm an epidemiologist, I've with post-licensure trial data, and I'm pretty for government oversight.

Because we have the "nutritional supplement" market as a working example of "We give people stuff without bothering to see if any of it actually works".
What a fantastic read! I wonder if they get any tech or materials from SpaceX?
This really bums me out :( -- My girlfriend and I have been making use of homejoy a lot lately, and it has really been helping us keep up with the house.
I understood your point of view. Netflix is better than us now, that's a fact.

I personally don't think Netflix could be exhaustive in every way because the curation work is very important here, to satisfy every segment in the world.
Netflix is not in Africa though,

Drama fever, Crunchyroll, viki.com did well in their segment. And we intend to be the best in ours.
I also wonder if there will be a way to "update firmware" on the fuse, so as to disable it, allowing remote self destruct mode. The advantage of a dumb fuse is it's basically going to work unless the laws of physics change, even though it's not as precise.
Sell them, not that they're worth anything now, keep the rips, steal all the new stuff and don't feel guilty about it. You've been milked enough.
Seems like much of that short-term profit would easily be negated by increased frequency of maintenance due to wear-and-tear on driver vehicles.
Does it cause it to go to plaid?
> They're very similar, 2.8 vs 2.9 is not that big of a deal.

It's not? At these rates higher acceleration is more than exponentially harder to achieve, that is the closer to zero you get. Someone should link a nice graph.
Nice writeup, the dominant color approach looks promising. I've also tried something similar using averaging.

Not sure if this is any better than your solution, but my approach with ffmpeg was this command:

ffmpeg -i "$myvideo" -r 1 -threads 4 -s 320x240 -vcodec mjpeg img%04d.jpg

The -r flag sets the framerate to 1, which in my understanding gets a frame per second. I also used all the cores of my laptop. The -s flag just does the same thing as your filter, though in my case I also fudged the aspect ratio of the resulting frames. I chose to save in jpeg to save some minuscule space.

In my approach I squashed each frame horizontally to one pixel, so I get vertical slivers that average each frame. Then I just added them all together horizontally. Here is the result of that for Requiem for a Dream before resizing [0] and after [1] to get a better overview. In terms of usefulness it might not give too much information, but it's nice to look at and sometimes you can even spot individual scenes.

At least they have a sense of humor about themselves:

request.onsuccess = function(event) {

The Ariel Atom 500 (with the V8) is a little bit faster at 2.3 seconds 0-60. However it's not really a daily driver kind of car like the Tesla: https://www.youtube.com/watch?v=SIiWhWpzFQQ
You should steal much more if you've already paid for it.
Mercedes-AMG E63S 4matic with 590hp ~$105k does it in 3.5s, and that is very fast. The Tesla is indeed ludicrous.
Pakistan Government Server Got Hacked
If only we had some way know knowing when we should sit, stand, or lay down. We need millions in government-provided funding to figure this out for us.
"Taking pride in what I do, and doing it well" is a kind of passion that transcends "Is this the best job ever?" and one I've definitely seen cleaners and other people with "bad" jobs care deeply about.
Most physics isn't done with space telescopes or particle accelerators; and very few groups require billions of dollars of equipment (considering the NSF budget is less than 10 billion dollars, there wouldn't be much to go around). Theoretical physics in experimentally relevant fields is about as cheap as its ever been; you really only need professors, a building, whiteboards, and travel funds.

And believe me, there are a lot of experimental physicists doing excellent work with two guys in a garage levels of equipment.
>This sounds like it will be an absolute disaster:

It does; but isn't the status quo also an absolute disaster?
Yes, basically slowing down enough to orbit Pluto would have required too much extra launch weight, although the difference isn't enormous. The best candidate, a nuclear-electric propulsion system, would have approximately doubled the spacecraft's mass. This Stack Exchange question has more information: http://space.stackexchange.com/questions/9851/requirements-t...
I believe this article today is actually a response of sorts to that one, judging by mikeash's comments from when it was posted here 2 weeks ago:

https://news.ycombinator.com/item?id=9830646
I run a company similar to HomeJoy in Japan, and I disagree with most comments here.

1. Those who claim cleaning is not a "skilled job" should get off their keyboard, spend a day cleaning their moms house, and get back to me when they learn they are 3X slower than a pro and destroyed something with bleach-based spray.

2. It feels like nobody here actually read Adora Cheung's quotes about multiple lawsuits coinciding with investment timing. That is obviously the reason they shut the doors.

3. Those who claim flaws in matching business model are to blame are making non-quantitative assumptions. Just ask yourself, how high of a percentage of users sharing direct phone # would cause a growing company to collapse? Also the supply side risks losing stable income or insurance coverage.

I do quite a number of things much differently than HomeJoy, and quality control being a major one. There are certainly a lot of challenges and operational complexity to keep my team innovating. Japan has the highest customer service standard in the world (and hardest to satisfy customers), which is great for building a more solid foundation. If any hackers are leaving HomeJoy and want to move to Tokyo, I'm hiring!
Yes. To get there in less than ten years, it had to be low mass, since a high mass spacecraft would require a launch vehicle we don't have. Since it is low mass, it can't take enough fuel to slow down. Thus, a flyby. Getting the Cassini spacecraft into orbit around Saturn was quite a feat. Pluto is even harder.
Tesla's seems to be beating a dead horse! Don't get me wrong; I love what Tesla does but making a faster production car seems to be an answer to the critics who I think have already taken home the message that the electric car is as fast as the best IC car!

I think what they should address is getting out the affordable Model 3 as fast to the market as they can. They may loose the game if the incumbents beat them to it. They would need volume to sustain their production and maintenance costs. Once every manufacturer gets onto the electric wagon, a lack of wider adoption, could become their Achilles heels.
Aparently the new Roadster will. [1]

Those are overhyped so as to be buzzwords. All the IO-MMU really does is make the data come to and go from a certain point of memory. What it does when it hits the system software or applications is a whole, different risk area. See OS process separation vs all the ways it's bypassed with app & kernel-level vulnerabilities.

So, you consider that the FPGA might sabotage data you send through it or what comes from it. Be monitoring or doing validation on both.
As i said, I hate the world Niche, and I never use it only to say I hated this word,

African descent movies are so diverse. We have an African Diaspora all over the world which produce a ton of contents you never saw, you don't even know their existence and thant's our goal to diversify the point of view of a maximum of people. Yes Netflix has resources, a lot of resources but we know our market well. They need to catch up, that's my word for now, fight is on
Is that why we're doing physics research? Practical technology?
OK it is the game I'm thinking of. I remember the set too. Never thought of it as modeling fog of war before, though.
Good points. I came to write 1) that they were trying to turn a match-making business into a transactional business (apparently unsuccessfully) and 2) that the labor problems sound more like an excuse for what was likely just a poorly run business.
a tenth of a second for a 0-60 time actually is kind of a big deal...the closer you get to zero the harder it is to shave off that additional tenth...traction also becomes a very real limitation...bravo to the Tesla team.

Also, i'm pretty sure the Tesla IS the only $100k luxury sedan with that performance right now. Very few pure sports cars make it under 3s.
Nice discussion, thanks for posting.
>but huge penalties if they approve a drug or device that goes bad.

What penalty does the FDA face?
The US government's "cybersecurity policy" is completely and utterly inadequate. Their thinking so far has been "well, let's leave aside the actual security stuff, and focus on getting cyber-weapons - the more cyber-weapons we have, the scarier we'll be and nobody will touch us!"

Yeah, maybe that can work against a mid-level country like Iran. But what about China or Russia? Are they really going to be dissuaded from hacking US agencies and private companies because the US will hack them back? Are they going to be afraid that US threatens them with actual war? Nope.

Then there are also the "guerrilla hackers", which could be anyone from random hacker groups, to cartels in Mexico to North Korea who doesn't care if you hack back its hundreds of PCs. Your scary cyberweapons aren't going to dissuade them either.

The US government needs to stop making encryption and strong security (that itself can't hack) public enemy #1, and instead actually promote them in every single agency and raise security standards that private companies have to meet as well, especially if they are storing sensitive customer data.

As Schneier said earlier, the US has the most to lose out of all the countries by actively trying to keep the web vulnerable.
Well, they will be a fraction of what they are today when the taxi company no longer has to pay an hourly wage to the taxi drivers
It's a $10k upgrade, not cheap! I wonder which Ludacris song[1] was the hold music looping before today's Tesla press conference call...

"Track day toys". Eg Caterham 620R, Ariel Atom 3.5r. I've got something very similar to a 620R, animal machines. Absolute animals. Stripped down, no creature comforts, really for one thing only...
Do you schedule the customers close by to minimize travel time for your lawn care guys? I know cleaners that drive across town to jobs, effectively losing money while they're stuck in traffic. I don't know if Homejoy did that.

To incentivize that, you could offer discounts for neighbors who use the service together. If Homejoy had a bunch of apartments in one location, then cleaners would make more money per day.
Well, I worked in medical devices for several years, and I think the level of FDA oversight was actually pretty appropriate.

There are two dangers: letting a bad device into use, and preventing a good device from entering use. And both "good" and "bad" are relative here, so it's a tricky dance. Personally, I thought the FDA was doing about right. They forced us to really have all our ducks in a row, but that's actually appropriate.

But with all that said, I personally found it a horrible environment for an engineer to try to live in, and I got out.
Basic security measures were taken in the valuables room. The jewels out-of-site and in the box were all fake. Whether the jewels were fake or real or whether anything was taken or not doesn't matter right now.

It was the experience of that interaction that mattered and I didn't feel that Homejoy lived up to that promise.
You're missing the point. The apartment is their property, even if the mess isn't.
> Is it because the fuel involved in slowing down the spacecraft would be forbiddingly heavy?

Yep. It was traveling about 31,000 miles an hour relative to Pluto when it flew by. You'd have to decelerate to about 3,000 miles an hour to get under Pluto's escape velocity - that's a lot of speed to bleed off.
Note that 0 to 60 is not always what matters.

I have a Porsche Macan S (small SUV) which has 0 to 60 times in the 5 second range. But the acceleration from 50 to 95 (the point that your realize you are going to fast) feels almost split second.

The 2012 911 that I had had much better 0 to 60 times (in the 4's) but even with a 7 speed manual transmission didn't have the kick that the Macan has at the upper end. [1] (And it's really pretty neat to hit the gas and in an instant be practically at 100 miles per hour. Helps greatly with passing truck..)

Likewise if you take a test drive in a Cayman S which has better 0 to 60 than a Macan S it feels quite frankly like a "pig". I had a brand new loaner [2] and drove one for about 100 miles and went to town with it.

Lastly, engine noise is pretty cool at least the way I have experienced it.

[1] Generally you are going to do more accelerating once you get to 40 mph than you are from a stoplight at least that is what I have found.

[2] Side note I have found that with the Porsches that I have bought they do get better once they are broken in (2k to 4k miles..)
I like the Spaceballs reference. https://www.youtube.com/watch?v=mk7VWcuVOf0
Should that happen, my guess is that they would be quite happy to sell their batteries to everyone else.
> Because we have the "nutritional supplement" market as a working example of "We give people stuff without bothering to see if any of it actually works".

Or, even, if its actually the stuff that it claims to be, much less whether the stuff it claims to be works.
Also, the origin of the FDA was a time when people could advertise and sell "medicines" which failed to treat or cure anything, and routinely lie about the ingredients and their medicinal properties (or lack thereof), a problem which the free market was conspicuously failing to solve.

So now, anyone can sell medicine, but if they want to claim it's effective for some disease or condition they have to actually back up the claim.
How can they get that many amps out of the battery? It seems like you'd need a capactior to have that kind of power?
Ok, I found it myself. It's "Beast Mode"! [1]

Hopefully once they iron out the kinks in space travel they can release it to the Tesla with a software upgrade, or maybe an even better fuse!
1. Totally agree.

2. I think that's just a convenient excuse for what was more likely a poorly run business.

3. It definitely seems like a match-making business to me. Perhaps things are different in Japan. I could perhaps see wanting a few different providers for diversification.
Exciting times is a bit of a stretch. I was cutting black and white pictures from newspapers of Viking on Mars when I was a kid. 40 years later we're finally checking out Pluto.

Things will get exciting when the cost drops 100x and we're beaming back hi-def video and images 24x7 from all the planets and moons in our solar system.

Let's dream a little bigger and set the goal much higher.
While I'm sure they gathered interesting data during the traffic surge, I'm not sure Amazon would want to damage their brand by risking failing so loudly with so many eyes on them. I'd bet that Amazon already invests heavily into load testing and ensuring the reliability of the AWS backbone their retail site runs on.

I think the real driving motivation for Prime day was to drive Prime memberships. I get the impression that Amazon is betting on the recurring payments and increased volume of sales generated from Prime members to offset the ongoing cost of free shipping/other services and user acquisition costs like Prime day offerings.
Well, Google doesn't need to increase their search engine ranking...

And they link directly to Wikipedia, driving traffic to their site, so they're not really wrongfully stealing the data.
I'm pretty sure they're working as hard as possible on that, but the key to reducing the costs is the battery packs and that won't happen until gigafactory comes online. Other manufacturers will face the same cost issues but won't own their own gigafactory
Healthy seaweed tastes like bacon
When I first heard of this company, I thought, "Too small a niche to grow--they'll never survive". This is a service for a very limited market--rich people who don't already have a housekeeper and can't manage to keep their houses clean. Nobody I know socially would actually pay someone to clean their house for them.

Yet, so many customer testimonials here on HN. Are there really that many people so busy/well-off that they can't take a few minutes once a day or so to pick up after themselves and rather pay someone more than their mobile phone bill to do something so trivial? I guess I was wrong about the market size but damn...
Interesting, my startup has the same name (with another domain)
No-one needs this, I predict accidents.

I hope insurance companies can determine which models have this and inexperienced drivers should pay more.

Just hope no-one kills anyone.
No I am implying that companies that avoid paying them are getting an unfair advantage versus the companies that treat their workers as employees.
At high levels of current it takes pretty drastic measures to break the circuit. Even if the conductor melts away you can still have arcing, turning the air into plasma and a replacement conductor.

Kind of nuts that they had to account for that in a car.
No, IMHO. The status quo is an attempt to walk a knife-edge ridge with cliffs on both sides. There are failures on both sides, and different people getting burned by the failures on each side. Both groups decide that the status quo is an absolute disaster, but disagree on which direction the disaster is.
There's of course a third danger: all the people that won't use their skills to try to develop new technologies due to the costs of FDA approval and the lack of knowledge about those processes. What you end up with is handing the market to huge corporations that can afford the not-product-related huge upfront costs, and who have the institutional knowledge of navigating the approval process.

Its interesting that SV is often criticized for not taking on these "big important problems", but at the same time these are markets that can be impenetrable given that the entire fate of the company can be in limbo for years during approval, requiring tremendous up front investment that is harder to predict.
Sure, the farther you get from a place, the less people know about those distinctions. Americans will say that a restaurant or hotel has a "European feel" to it, even though Europe is also a diverse continent.
Market segmentation. How do you get people to pay you another 10k? With a widget that is useless but has huge bragging value. People who don't care about 10k will spend it on this, and those who do care will have no different lives.
Not sure if the offer is rhetoric or not. No contact email, no business name. Is it related to #1 as a joke-of-sorts?

x100. There is a lot more variance between two cleaners than say two Uber drivers.
Sorry if this is noted somewhere but when will an English version be released? Are you going to get movies that are actually from Africa? (nollywood)
I assume that means awd for the new roadster; Otherwise I don't see how they could do tires.
Congress (who controls their budget).
> I think what they should address is getting out the affordable Model 3 as fast to the market as they can.

I agree, but I doubt this project took any manpower or resources away from the Model 3. If anything, it'll generate some extra cash to help with their R&D.
If NASA approves additional funding for NH next year, it will be flying by another Kuiper belt object in a few years. It looks like either 2014 MU69 or 2014 PN70.
