djkz··on Ask HN: How to learn sales?
Bob Moesta's new book has some good pointers on it, it's currently on sale on Amazon: https://www.amazon.com/Demand-Side-Sales-101-Customers-Progr...
djkz··on Humans not users
Just saw another day on Twitter after a brand referring to their followers as beeflings. https://twitter.com/mulegirl/status/1088946637454471169?s=19
djkz··on Alphazero crushes Stockfish in 1,000 game match
That's exactly how it's trained, it competes against itself in a millions of games and updates it's neural network with the heuristics of the winning instance.
djkz··on React Hook recipes every day
I can't wait to start using hooks. I think the main power of them will be code reusability, like pulling a bunch of hooks into your html and having out of the box drag and drop, animations, etc, all while keeping the code clean and readable.
djkz··on Elon Musk's latest company: Pravda
To elaborate, Pravda means "truth" in Russian, and that was the name of the state propoganda newspaper in the soviet union.
djkz··on Scammers Using Fake News to Screw with Bitcoin Investors
There is an interesting Twitter thread pointing it to Chrysler as the root cause https://twitter.com/KashannKilson/status/953740344369102848
djkz··on How to detect lies with a storytelling technique
This reminds me of Jobs To Be Done (http://jobstobedone.org/) interviews style that dig into emotions of why customer switched to a different product.

The interview jumps around the story looking for any events that moved customer to or from new solution, and digs into the emotions associated with each event to get customers to recall all details.

djkz··on Show HN: WorkHub App – Make money on the go with simple tasks
I would put a paragraph describing the value proposition somewhere either on front page or linked from it for both people posting tasks and consuming them.

Edit: linking to the main site from the landing page would solve that problem.

djkz··on ActiveJob – gem for defining background jobs in Rails
To give an example let's say you have a mailing list with 1000 people and you want to send out notification. You push "notify " button, but you don't want to wait for your app to go through 1000 people and send them email until it responds again. You also don't want to wait until midnight for crontab to start processing all requests.

Background jobs takes that 1000 deliveries job and puts it into the background queue, then a worker starts sending those emails right away. Meanwhile your app returns from your request instantly so you can continue doing what you were doing while the job is executed in the background.

djkz··on After Technology Destroys Capitalism
I think the idea is that you can't hoard reputation and you can't trade it.

With money the more you get the easier it becomes to manipulate the system so you can acquire even more, with reputation you go from no reputation to maximum reputation in one particular subject.

djkz··on SimCity Offline Is Coming
I believe that they used online mode as an excuse to limit reviewers to only be able to play for 8 hours, so many of the limits were not apparent.

The game really only starts showing it's shallowness once you filled up one city space and started on your next one, only to come out with a homogeneous clone of the first city.

djkz··on Oculus VR raises $75M
I've used the low res dev kit and the immersion it provides it great.

I believe this will have a ton of applications from VR conferencing to going to virtual concerts to even spectating sports with an isometric view of the field instead of the 2d projection.

djkz··on A Penny Saved: Psychological Pricing
When I played on World of Warcraft Auction House the main advantage of this tactic was the fact that it placed your items before all evenly priced items. I've exploited that for a while to move large amounts of inventory.
djkz··on 8pen + Leap Motion
I believe the best application for this will be virtual reality headsets - such as Oculus Rift, where you can have virtual screens but having a keyboard would not be practical.
djkz··on Compromised Keylogger-aaS exposes network of Nigerian 419 scammers
So instead of just putting it in spam folder, we should have AI try to impersonate a human that is getting stringed along for a scam. It's both an opportunity for passing tuning test and making scammers not be able to ever find a real target.
djkz··on A Startup Reading List
Personally I've also found that I like to mix a little psychology books into my business readings, here are a couple that I personally liked: Influence - http://www.amazon.com/gp/product/B002BD2UUC/ref=kinw_myk_ro_... and What every BODY is saying - http://www.amazon.com/gp/product/B0010SKSTO/ref=docs-os-doi_...
djkz··on The idea maze
If you are interested in The Customer Factory here is a video preview for the book https://www.youtube.com/watch?v=5iq3xDul0JY
djkz··on Want to Block Common Passwords? Sorry, That is Patented
I'd stay away from looking up things you might infringe. You will be liable for treble damages and most of the trivial things are probably patented by somebody (http://en.wikipedia.org/wiki/Treble_damages).
djkz··on What The Rails Security Issue Means For Your Startup
How feasible would it to have a gem that sits in middleware that would check for possible attacks before the string gets any further and block/share IPs of people fishing for exploits?

I could see it as a service company that shares blacklist info between sites and can even find new exploits from the "bad" requests.

djkz··on Show HN: I love Essential Mixes. So I made this.
Any chance of adding some Solid Steel mixes to the collections?
