bdwalter··on Evernote, the bug-ridden elephant
No, I work for iovation. We do large scale realtime fraud prevention for many of the largest banks and internet businesses through a shared network of device reputation.

There's a lot more to Portland than just Puppet, though we do use a ton of their product. We love those guys.

bdwalter··on Evernote, the bug-ridden elephant
I have been a loyal Evernote premium payer since 2009, and using it even longer. For a long time I recommended it to friends but since have stopped. I have developed some concerns with it over the years.

1. Fear of data loss... it's probably the largest part of my mistrust of all these dang cloud services that want to control/own me or otherwise lock me into their service. I run a 99.999% uptime, extreme scale, SaaS business across multiple active/active data centers, I know exactly what it takes. It’s incredibly hard to do, and I don't trust anyone at a rapid growth company to do it right. In the ever constant scheduling battle between features and doing it right, features frequently end up winning, especially in consumer focused SaaS business with meaningless SLA’s. My Evernote library is clearly much much more important to me than it will ever be to Evernote. No amount of marketing spin will ever lead me to believe otherwise. This really is my own hangup though. At some point I may just get over this. To their credit, I have only ever lost a few notes in the 4-5 years I have been using the service.

2. Tight lock-in (the cynic in me always says it’s clearly engineered this way) to the platform, frustrating process to export my notes to another tool. This is a problem across the industry. Everyone playing the lock-in/stickiness game. Portability is key. A simple text export of my notes would go a long way to make me happy. I really don’t want html exports of my text notes.

3. Security of their cloud service...frankly, I don't trust anyone and wish I could store my evernote data on my own; self managed; self encrypted; shared storage platform. 2 factor was a nice step in the right direction. Self managed encryption keys is when I will stop whining about it… I understand this makes a lot of things hard, and am willing to forgo some features to get this feature.

4. Lack of reasonable support for Linux. Evernote is now the single sole tool keeping me from dumping my Mac and moving to linux... Yup, note-taking is that important to me. I have tried nevernote, everpad and the like, but they are still pretty weak. I understand this isn’t Evernote’s problem and Linux is a very small market, but its a big deal to me.

5. A frankly lousy text editor. Seriously, I keep expecting this to get better, and it just never quite gets there. And don't get me started on tabs and indenting. I often edit notes in mac textedit and then copy them into evernote. Not because TextEdit is great, but because its predictable and just works. I'm not looking for advanced features here.

6. Strange as this may sound (I may be using the tool wrong), I really hate marking things off my list like at the grocery store. It takes so dang long to mark off a list while pushing a shopping cart and fumbling with a phone. I now print my list out and cross things off with a pen because its so way less frustrating... This may be an edge side use case, but still... the phone apps (both droid and iPhone) are not wonderful.

I fully subscribe to the belief that I am a weirdo, and these are really just my perceptions and random thoughts. I have remained an active, albeit reluctant user, and at this point plan to stay that way for at least a little bit longer. I always used to joke that if evernote, things, and dropbox ever merged, I would happily pay double. These days though, I am looking to support my own stand alone instances of these types of tools without being tied to 3rd party cloudy services so tightly.

bdwalter··on 5 Things Every DBA Needs To Say To A Developer
Clearly this goes both ways. If I had a buck for every time I encountered a developer that was a douche to my dba's, I would be a very rich man. It's a two way street my friends. I think this speaks of an environment primed for devopsification.
bdwalter··on I Wish Nest Did More Than Thermostats
I find these guys very interesting http://irrigationcaddy.com
bdwalter··on Ask HN: Questions you would ask a candidate for senior operations engineer
This question has sparked some very interesting conversations w/ candidates for me lately.

"Explain to me your understanding of the devops movement and the value and relevance to our industry and specifically what has this meant for you over the last couple years."

bdwalter··on PagerDuty (YC S10) Raises $10.7M From Andreessen Horowitz For IT Alert Service
We have about 20 users in PD. They live and die by this system. Love these guys and have never seen a product like it.
bdwalter··on Show HN: I invented, built, and released a 360º Video Camera.
Interesting, these guys have been building 360 cameras for years, but in a clearly different space.

bdwalter··on Preventing online payment fraud
Take a look at realtime device identification and shared reputation services. This allows you to uniquely identify the end user devices accessing your site and assess their reputation and fraud history across a shared network of intelligence. Services like http://www.iovation.com are massively effective at fighting fraud.
bdwalter··on Vizio Ultrabooks
Anyone have any indication as to how well they support Linux? Specifically Ubuntu or Mint?
bdwalter··on OSX apps that keep you hooked to your Mac?
Pathfinder
bdwalter··on Ask HN: Just ordered my first Mac- what apps should I know about?
I'm a big fan of fluid http://fluidapp.com/ which lets you containerize web applications into a single app like thing. Also for mail, I'm a big sparrow fan.

If you need flowcharting/diagraming similar to Visio, Omnigraffle is great.

bdwalter··on Which program should I learn RoR or PHP?
I tend to agree with this. There is a lot of work out there on the PHP side.
bdwalter··on Amazing 300,000 image timelapse of Portland
As a portlander, I find this very cool.
bdwalter··on Ask HN: Using Cheat Sheets
I don't use printed ones, but I do maintain a personal wiki where I keep all of my documentation over the years. It's extremely useful to be able to search my cheat sheets across my history.
bdwalter··on Show HN: My afternoon project - Pink Noise mp3.
I have a pink noise generator in an old audio spectrum analyzer. Guess its time to dig it out now.
bdwalter··on Ask HN: How do you read Hacker News on an iPhone?
I use this. http://newsyc.me/
bdwalter··on Republic Wireless routes through AWS East
I think this is a great idea, I can't wait to try it.

Hopefully one of the big carriers doesn't kill ^h^h^h^h acquire them.

bdwalter··on How I Did It: Hartley Peavey of Peavey Electronics
Having bought 10's of thousands of dollars of sound equipment over the years, much of which was from Peavey...this is pretty cool.
bdwalter··on What should I ask for when negotiating a CTO position in a funded start up?
Forward vesting... you want it. When/if they sell the company you do not want a bunch of unvested stock options disappearing. Has happened to several folks I know, and myself in the past. Forward vesting causes all of your options to vest in the event of a change of control, or sale of the company.
bdwalter··on Castle: Reinventing Storage for Big Data (OSCON Talk)
I was there for this presentation today. Interesting stuff. Looks like it could address some of the issues we are seeing w/ Cassandra today.
bdwalter··on How to make wifi work at tech conferences
At the risk of sounding like a plug... Xirrus can do this. They kept up at interop just fine this year.
bdwalter··on Ask HN: How to mitigate DNS provider issues?
Hire dyndns and don't worry about it again.
bdwalter··on Poll: Is HN your main online news source?
I find it very interesting that I always find articles on slashdot 3 days after I read them on HN. HN always seems to be super fresh.
bdwalter··on If you could give a book to your younger self, what would it be?
Anything from Dave Ramsey.
bdwalter··on Ask HN: What SSL Cert Provider Do You Use?
We use digicert and have been super happy with them.
bdwalter··on Poll: Are you using SSDs?
We are writing quite a lot more than 10GB per SSD per day on ours, and we have run into lifecycle issues. Of course, we are running a lot of these SSD's and striping across them with OS level raid, so we are doing a lot of write IO.
bdwalter··on Poll: Are you using SSDs?
We are using MLC SSD's in production for our Cassandra clusters. It is very important to consider your workload when implementing SSD's in a production application.

There are MLC SSD's and SLC SSD's. The former being reasonably priced (think <1000$), and the latter costing in the neighborhood of 5-10k per drive.

MLC SSD's have a fixed write lifetime and will die or degrade after a certain number of writes. SLC SSD's have no such limits.

Cassandra for example has a very predictable write workload given our application, but other datastores (like an active write heavy mysql OLTP DB) would kill an MLC SSD very quickly.

We are using Cassandra to drive an API that must service thousands of requests a second but also with sub 100ms response times. Not a typical web use of Cassandra. Response times from hard disk just were not fast enough for our needs.

A new type of MLC is hitting the shelves now too. Enterprise MLC... supposed to be more resilient to the issues MLC ssd's have faced.

We are using OCZ Vertex.

bdwalter··on It's time to put the brakes on red-light cameras
In Portland Oregon they are now reducing the yellow times in order to increase red light camera revenue. Somebody needs to put a stop to this madness before too many people die.
bdwalter··on Lucene wins
What has lucene won?
bdwalter··on Ask HN: How do you find time to code/build your business in the evening?
I have been trying to move to this model for about a year now. When I can pull it off, this is the best thing in the world. Problems arise when your day job runs into the night, and you cannot get up early to do job #2.
