Hint: how prevalent are handguns in Germany?
It would depend on the lander or even the landkreis... it's roughly 30 guns per 100 persons averaged over Germany, in my landkreis it's just below 90 handguns per 100 persons (5 years old statistic). That's just privately owned handguns... if you throw in the hunting weapons and service weapons, there's probably more weapons than people.
8. Oracle managed services failed to grasp what a replication timestamp was. For a week, their daily report was indicating that the replication had worked flawlessly even tho the timestamp on the target hadn't changed.
9. Oracle managed services sent me the daily report of another company, with financial information, on more than one occasion. They have also obviously sent my customer's data to other companies.
10. Back when Sun was still a separate entity, they won a 4 years staffing/project contract where the first action point was implementing unified authentication with LDAP (the site was mostly Solaris 8, with some HP-UX and a pair of AIX boxen). They only successfully delivered this feature 7 years later, after three contract extensions, when the whole site had been migrated to Solaris 10. They were surprised when they didn't win the new staffing/project contract and even more surprised when the customer massively migrated to RHEL.
- Automate, everything
- Do not hide behind forms, user-filled requirements waste even more time than collecting the requirements yourself
- Get involved in project as far upstream as you can
I never said it was an honest measure, but it is the measure used by the hard drive industry. It is also very similar to quality measures in many other industries. You take a reasonable sample, run a test for a certain amount of time and infer/extrapolate reliability figures based on the test. On the back-end, you redesign your process to eliminate as many variations as possible on the manufacturing side.
The alternative would be to really test the disks for 3-5 years in a lab before releasing them on the market, or really testing a large amount of drive trains for 10 years and so many miles before releasing to market. The first company to really do that will go bankrupt before shipping the next generation of devices.
The same way it is calculated for rotating platters, I would guess.
The lab sets up a test with 1000 drives for 1000 hours. If one drive failed during the 1000 hours, the MTBF will be advertised as 1,000,000 hours ([1000x1000]/1). [short time period] * [number of pieces tested] / [number of pieces tested which failed within that time period] = MTBF.
He may not have lied...
I usually ask a variation of that question... What's something you see about yourself as a potential weakness for this role?
The question is open enough that you don't need to pick your worst weakness. I actually don't really care about the potential weakness, I expect the candidate to be mature enough to be honest/candid and to come up with an improvement plan or a way to work around the weakness. Answering "I don't have any weakness" is usually a sure way to be put in the circular filing device.
