I'm finishing a game I started writing before my first daughter was born. The in-laws have been beta testing and they like it so far!

They genetically engineered a kind of bacteria that divides into non-living 'nanocells' that can't multiply further. These cells contain a special kind of RNA and a cell entry mechanism that lets them enter the cancer cells. The RNA interrupts the cell's ability to prepare for division. The article kind of implied that these nanocells follow the bloodstream pathways that cancer cells open when they metastasize.

The researchers main concern was whether those nanoncells would also enter healthy cells, but the tests seem to show healthy cells were not affected.

You might even luck out with those heuristics. Simulated annealing often results in the shortest/best/lowest-energy-state solution by accident.

Kind of like proving that you can't solve the halting problem, it lets us put to rest the idea that you can reduce the complexity of NP problems to a deterministic polynomial solution. The collective brainpower can be used to solve other problems.

I saw a demo recently where someone used Microsoft Bot Framework for what you described. Can't find the video at the moment, but might be worth looking into. [https://dev.botframework.com/]

New comment by bottombutton in "Ask HN: Slow engineers, did you get faster? How?"

bottombutton — Mon, 22 Jun 2015 07:01:03 +0000

This struck a chord.

[Edit] I had an essay explaining why, but long story short... it's just that I had the same experiences on my old team as you described, so I left out of frustration for what I consider my dream job. Now it feels ruined because I can't really start fresh, and I moved halfway across the country to take this new role. How are we doing on time travel? Any progress?

Ask HN: Slow engineers, did you get faster? How?

bottombutton — Mon, 22 Jun 2015 04:48:36 +0000

After four years, I left my first team in March to join a new team at the same company. Now it's performance review season, so my old manager forwarded some notes to my current manager about my prior work. Basically it said that I had solid results, wrote some really stable code, "championed" testing and testability for the team, and that people liked working with me. I haven't seen it yet, but apparently it was a lengthy essay.

But he also added that the one thing that had been keeping me from moving from SDE I to SDE II was my velocity at turning out deliverables. I'm basically the last one of my peers who hasn't made the jump, and that was the ongoing reason from my old manager. I'm getting passed by newer engineers pretty regularly now, and I've been at my current level for about three years.

In the last couple weeks since my new manager got that letter, she's seemed really concerned about my velocity. It wasn't until this Friday that she had read anything about it. Yet in the same time span, the new-guy-on-a-new-team feeling was pretty much gone, and productivity was up. I got put on a pretty high-visibility, high-impact feature for this month. Before, I think my manager saw me as ready. Now I think she sees me as a liability.

I was starting to get worried that I'd never meet this speed expectation at my old job; but now I'm extra nervous that if I slip on any deadline even a little bit, I'll seal this reputation with my new team and make it my label from here on out. The Slow Guy. Sure he's nice, and he writes maintainable, reliable code... but if we need it done soon, might as well give it to an intern!

Q: Did anyone else shake a reputation for being slow? Is there any hope I can do to put this velocity thing to rest and catch up with my peers? Or am I just a B engineer who peaked right out of college?

PS: I'm getting married next month. Will I have to choose between my marriage and permanent 12 hour days?

SAP too. Even newer, cloud-based companies like Workday are looking like very promising contenders for the same small/midsize businesses as AX, GP, NAV, and SL.

This is neat... I love projects like this. When the number of clusters is unknown or hard to predict ahead of time, I'd lean toward something like affinity propagation or mean-shift. Why k-means?
