Pingdom with email2sms gateway for external/global checks and zabbix for internal checks
carl_··on Ask HN: How do you stay (somewhat) healthy?
honestly?:

- eat crap one day, eat healthy other.

- don't own a car/walk and take the stairs rather than lift.

- avoid public transport (where possible).

- work hard.

- get a good full 4 to 9 hours sleep per night.

- do some light weights every other day (or when bothered).

- drink lots of juices and waters and avoid fizzy drinks.

- alternate drinking beer and shorts without mixers.

carl_··on Ask HN: Monitoring historical server resource usage on linux?
I use zabbix over ~<1000 physical and virtual hosts for historical resource usage and alerting.

Cacti for network traffic monitoring (and alerting using thold plugin).

Smokeping for network latency and availability monitoring and alerting.

carl_··on First rule of ant traffic: no overtaking
In "Critical Mass" by Philip Ball chapter 7 covers "The inexorable dynamics of traffic" which is highly worth a read if this subject matter interests you. There's also some very interesting sections on crowd dynamics and route finding.

carl_··on Ask HN: any suggestion for DNS providers? (need to outsource my bind setup)
Last time I checked they charged per 1,000 DNS requests?
carl_··on Ask HN: any suggestion for DNS providers? (need to outsource my bind setup)
Enom have had several large scale outages in recent memory.

We've got nearly 3000 domains under our enom reseller account, I wouldn't touch any our domains on their nameservers.

carl_··on Did Steve Jobs just sacrifice Phil Schiller?
You've had it too good for too long. Consider Apples innovation in the last three years compared to any (or all) of their competitors... even the glorious Apple can't deliver at the rate they're expected.

The batteries better perform as well as Apple is claiming or this could be a major fail.

carl_··on Ask HN: Buying servers?
Also, Dell price-match RAM to crucial for me which might be useful for the servers you need.
carl_··on Ask HN: Buying servers?
Lots of great comments so not much add/kinda like others have said:

When dealing direct with vendors (Dell, Sun and IBM from experience):

1) Price you're given is not only based on current purchase, but future purchase. Telling your sales rep 'I need X servers now, but I expect to need a further X per quarter growing to X after X time' then they'll fight harder for your business. Basically, present your business as a growth opportunity to the vendor.

2) When speaking to your first sales rep, ask at what price/order level they generally deal in. The reps who handle bigger clients have access to bigger discounts.

3) Don't under or over-specify your machines without calculating your later options. Buying an extra processor for one machine now will be a hell of a lot cheaper/easier than buying the matching processor in 3/6/12 months. In the same respect, not buying that extra processor now might be more prudent because a new chassis with the latest and greatest processor in 6/12/24 months might be a better option. (should be part of your scalability predictions anyway).

4) Know your stuff.

4.1) We all know reps bs, by knowing what you're talking about you can reduce this tedium.

4.2) If you ask which processor is better, then it'll always be the more expensive one (or more importantly, the one with the better margin for them which is not always the most expensive).

4.3) mmmurf said it, but to re-iterate. Time = Money. If a rep is holding your hand too much, then you won't get as good deals.

5) Know your vendor and their enemies. 5.1) When is there end of quarter? 5.2) How have they done compared to comparable vendors over the last quarter, year, etc? 5.3) Which vendors are pushing X line/type of servers at the moment? 5.4) Have comparison quotes.

6) Specify a date when you will be looking to purchase. 5.1 has a MASSIVE impact on this.

carl_··on Ask HN: Cost of servers & bandwidth
If you're talking about providing a high capacity and quality experience then there's no alternative to colo.

I think the /Mbps prices quoted are a bit on the high side (you can get cheap transit at 5GBP/Mbps if you deal in reasonable commits). Apart from dropping your own line in there's no cheaper way I know of to achieve the quality.

Use of a CDN would allow less capital outlay on the standard http hosting (could use dedis, vm, cloud) and somewhat instant scalability. Once you know your traffic patterns your implementation options sometimes get made for you.

carl_··on Ask HN: Cost of servers & bandwidth
all valid points. The poster might also want to consider using a CDN if it's single request streaming files, otherwise colo as you said.

whatever you choose make sure it can scale fast, but at the same time (depending on your presentation of the media), there's always the option of piggybacking on someone else (like youtube) who's made the infrastructure investment.

carl_··on Advice for job seekers (colorful language)
Brilliant! She seems to 'punctuate' like an English man and describes exactly what I do when culling resumes from the pile on the first pass.
carl_··on Edinburgh Hacker Meetup wednesday
Sounds interesting, is it anything to-do with http://geekup.org/events/ ? I was thinking of checking out the Sheffield one.
carl_··on Ask HN: What would you put on the wall behind your desk?
"It would say something about myself"

If I walked into your office and you gave me a "conversation starter" along that line, I'd think you had a chip on your shoulder. It's one thing to be proud of your achievements, a different one to use them as a crutch for your inferiority complex.

Been there, done that.

carl_··on Ask HN: Fair share deal between me and my cofounder
You're talking 65:35 of... zero right now. I'd say he gets that share if he sticks with it (meaning you stay in business) for three years.

Additionally if you make this such a large pain point, then are they the correct co-founder to begin with?

carl_··on Ask HN: One page site/app + advertising revenue?
Start without ads, gain your traffic, ebay your adspace and then advertise these listings in the adspace your selling. Depending on your volume, niche and longevity it might work.

Just an idea.

EDIT: Sorry, just saw noodles point.

carl_··on Does anyone have a medical marijuana card in SF?
i think promoting something on the 'drugs & chemicals of concern' by the DOJ alongside med-pot might be a bit of a hard sell to almost everyone
