…the conference without any interest, failure to comply with anything will result in cancellation. BTW, we have dealt with Hotels like Hyatt and Royal Orchid, and booked as early as 6 months, but never had been troubled this much.

The Internet Saga

Fast forward to March 2014, we check-in on 19th March to finalize few more things and look after arrangements such as backdrops, standees, sponsorship materials and other facilities like internet access. The only thing which was left with …

…quick configuration examples to demonstrate how you can get the tool up and running in 5 minutes. Btw. I think configuration examples can be really useful as documentation is bit unclear about some of it's aspects.

After we are successful with installing latest Innotop, simply type ‘innotop' command in our terminal and this is what most likely you will see: [RO] Dashboard (? for help) localhost, 0.00, 0 QPS, 0/0/0 con/run/cac thds, !localhost Uptime …

BTW - note Rows Sent here not being equal to rows examined while in reality they should be exactly the same for this benchmark. This is the approximate accounting of Performance Schema in action, though.

Now compare it to the sample for the same query in the slow query log in Percona Server SET timestamp=1392071614; SELECT c from sbtest where id=387872; # Time: 140210 17:33:34.837517 # User@Host: root[root] @ localhost [] Id: 95 # Schema: sbtest Last_errno: 0 Killed: 0 # Query_time: …

…default go to response that I've seen since working with Rails (that's DRY btw), this idea exploded. Note that I actually have NO data to back this up; it's just speculation. Regardless of the actual cause, I now see code like the following: before_filter :find_posts, except: [:show] before_filter :find_post, only: [:show] before_filter :find_commenters, only: [:show]

def index() end

def my_posts() @ posts = @posts.created_by(current_user) end

def show() end

Happily, there are many ways to productize your relationships with customers or your expertise as a consultant.

[ Patrick notes : The transcript below has my commentary inserted like this, as usual.]

What you'll learn in this podcast:

Why vegetarians do not give great advice on pricing hotdogs, and Hacker News comments about the inadviability of selling information very rarely come from people with actual budget to buy information

Keith Perhac and I are back with the 5th epsiode of the Kalzumeus podcast.

Keith and I both have experience working as consultants in software development and online marketing. People often ask us how to transition away from the feast-or-famine nature of freelancing, where you do very well when you're delivering engagements and getting them paid quickly, and then do very poorly when work dries up or you have invoice collection issues. One way to improve on this is building recurring …

BTW, using div operator is not necessarily the best way to split data, you may want these to be ranges by using a helper table in MySQL to define those ranges, mixing it with sql_query_range or something else, depending on how your data looks like.

Finishing line

I always loved how Sphinx scales out easily with as many machines you need and have been running it this way for many years now, however I think I don't utilize this feature to make queries even faster on a one-machine …

…knowledge about the new science of entrepreneurship has gone global, startup ecosystems are always local. ( BTW, you can read more about why in Brad Feld's new book, Startup Communities .)

We're grateful to the simulcast hosts, who have been enthusiastic about the chance to have people gather and discuss Lean Startup ideas. Eric Harper in Evanston, Illinois, for instance, told us that the "event helped to build our community and provided some substantive …

…the moment, it's the first two conditions that are the hardest to meet. Assays can often be developed using antibodies and/or aptamers (really cool technology, BTW), and for a proof-of-principle it should be possible to start with diabetes patients who have to sample their blood periodically anyway. The use of saliva or urine samples would be nice, but unfortunately most biomarkers will be in the blood...
