Five years after quitting a job, developer’s former boss asked for rapid tech support

Re: You need to plan for this

You do not give individuals access to resources. You give groups access to resources, and connect the userid to the group.

Bearing in mind this could be a suspension (prior to sacking) so need to reinstate them.

You remove the userid from the (few) groups and disable the userid ( you do not just change the password, because there are automatic "reset my password" tools).

If the person is reinstated you just connect them to the group. If you give individuals access you may have to remove/add the userid from perhaps thousands of resources.

I do password-less logon to remote systems using SSH - so you need to make sure that this is disabled as well.

Changing a password stops them from logging on... it they were already logged on before they got the call to HR, then they still have access afterwards, so you need to confiscate their laptop while they are in with HR.

As I said you have to plan for this.

IT department put sticky notes on the laptops to help employees log in

Our algorithm is so strong - we need to write down the password

I remember working with one of the test team, and as I was talking to him - he gave me "the Paddington stare". He said he was working out the password

You take the 3 letters of the month, move them forward by 3 letters, so Jan -> KBO, take the year and add 1 so 2026 becomes 2027 and put a ! or a ? depending on the parity of the month.

Wow I said - no wonder you were giving me the stare as you worked it out. No he said, I was looking past your right ear at the white board, where is is written down - it is the middle 8 characters of the 10 character string at the top, and I didnt have the right glasses on.

Manager showed off his DOS prowess – with a command that wiped data

Issue any command - whoops - any command but that one.

50 years ago I joined IBM and one of my first tasks was to stress test CICS (like an operating system for doing business transactions).

The stress test had every one in the test groups running tests. They were told to logon and issue any command on the "command reference". If CICS stayed up for 3 hours the test was successful.

About 2 hours in, I tried the CSMT,P,SHUT,IMMED command and suddenly there was panic. CICS had shutdown!

The person running the test asked "did anyone issue the CSMT,P,SHUT,IMMED" command. I put my hand up.

They restarted the test and pretended the shutdown didn't happen.

Next year they had automation which could simulate end users, and they didn't suffer from a dumb end user again.

Chinese e-tailer claimed 14-inch box stretched the size of a 9-inch tablet

Whoops wrong size

On one of my many customer visits, there was one group of people who had to carry two laptops around. They had asked for new laptops with big disks so they could dual boot, Windows, Multiple Linuxes etc.

The laptops duly arrived - with "the standard disk". The disks didn't have the capacity, so they were told to keep their old laptops with Windows, and use the new laptops for the Linux etc and their testing. When someone suggested it would be easier to get an external hard drive - this was rejected because they had already overspent the budget.

The person who ordered the laptops said that every one else didn't need such big disks, so assumed the request for large disks was not really needed.

'Invisible mouse' made a mess of PC rebuild

Customer says "This fix does not solve our urgent problem". We went back to review the original problem, and were convinced the fix should work.

Two days later we went back to the customer.

Us:"How big is the executable you are using"

Customer: 222222 bytes

Us: Well the fix is 333333 bytes

Customer: ah. (pause) AHHHH we didn't copy the fix across. Sorry!

IT manager approved downtime over lunch, but made a meal of it

Work expands

Many a time I've started on a short project to find the project expands.

I'll just turn off this server we found in a locked room - which hasn't had any fixes on for a couple of years

- Oh - there's a program running on it

- Contact the program owner - not available

- Contact their manager. No you can't just turn it off

- When was it last used - can you find out

- A day later I find the answer - last "end of year processing"

- OK thanks, can you move it to a virtualised image?

- Sigh - yes - .... Let's start on the paper work.

BOFH: If the meatbags can't agree on aircon, AI will decide for them

Don't turn the thermostat up!

I am responsible for a large hall. Some people come in, turn the heating on, and set the thermostat to 25 degrees. They think setting it to a high value makes it warm up quicker.

I can see from my phone the state of the heating, and turn it down if they turn it up.

Some people sneakily turn it up and then deny doing so. I fixed this by saying we'll need to get an engineer in to fix the heating, because the thermostat keeps resetting to 25 degrees. This will cost us £200 to fix.

I also suggested when it is cold, do not come in a tea shirt - but bring a fleece of pullover.

Tech support chap's boss got him out of jail so he could finish a job

I need a work permit for a weekend visit?

I worked for a large US company. There were cases when people were working in the US - on a visitors visa.

Because of this we had to use a tool which told us what Visa/Work permit we needed when we needed. It was based on a tool for US folk.

My first use of the tool told me I needed a work permit to spend a week in France, and I could get the work permit from an office in New York. I was in the UK, and UK passports did not need any visa etc.

Later on I was going to China to provide onsite support for the weekend, and spend an hour or two doing education on the new features.

I was flying in Friday night, and flying out Monday morning.

The tool said I needed a work permit for the education.

To get a work permit, I needed a permanent address - which I was told would take a month. I had to report to the Immigration office - closed at the weekend.

I raised this problem with the people who supported the tool, and ended up talking to an executive!

The executive said I had upset the staff on the help line. I replied the tool was stupid!

In the end the executive said just fill in what you need to get the tool to approve your travel.

'People's Panel' to check if UK wants controversial Digital ID will cost £630K

I would expect only 10% of the IT industry to be able to formulate a solid plan!

Let's ignore the trivial well rehearsed topic and start with an easy one

1) When my information is hacked - how do I get it reset? Do I have to go to the post office- what documents do I provide. My passport will not be valid because it's been hacked.

2) Bearing in mind the post office and the back office being able to change records with no audit records written, will there be an audit trail ( that I can see any changes made to my record)

How do you protect it from other people looking at it my record

How do I get notified if it gets changed?

3) If there is a power cut in London - will I still be able to use my digital ID - say in Scotland?

4) Will there be pattern recognition software watching the traffic, for abnormal traffic, or at unusual times?

5) When does the data get deleted? - Is it physically/logically deleted from the database - or just moved to an archive?

6) Someone has a nasty accident, and smashes their face up.... how will facial recognition work?

Bug that wiped customer data saved the day – and a contract

Accidental on purpose?

I was visiting a customer and was peripherally involved in a problem they had.

They had a home grown configuration file which had had change upon changed made to it - to the extent that no one knew how it worked. They had had meetings to discuss rewriting it, and thought the risk was too high of it not working.

I was at the customer for the weekend while they did a major upgrade, and they wanted all support people in. One person I was working with thought he could improve their configuration program.

At midnight, he found his changes made it worse; and then he found he was updating the master copy, and when he backed out his changes it didn't work. The previous backups were corrupted, so could not be used.

He bit the bullet and rewrote it from scratch.

I went to the hotel at 0600, and came back at 1500 for the next day's support. He was still there. In the middle of the night I found him asleep at his desk (for an hour or two).

Sunday night about 8pm the major upgrade was successful, and the rewrite worked.

The guy was hyperactive from coffee an doughnuts. He said that most of the work was understanding what was still needed, and what was junk left over from earlier systems.

His boss when told, was happy and annoyed (more happy than annoyed).

As I was checking some documentation on his laptop, I noticed some files saying backup of....

When I mentioned it, he said "you didn't see them I sort of caused the backups to be unreadable. I just wanted to fix this application"

Enforcing piracy policy earned helpdesk worker death threats

guns!

One colleague went to a conference in Dallas. He checked in, went to his room. He started to unpack, and opened the window to the outside world. A few minutes later a mirror in his room shattered. A "Drive by" had taken a pot shot at the hotel and into his room. He asked to be moved to a room on the top floor of the hotel.

A friend who worked in a "secure" company had an American colleague come to the UK on business - it was the American's first trip, so there were discussions like - yes, you need a passport.

One of the questions from the American, was "will there be somewhere to store my piece when in meetings?" After a few clarifying questions, my friend had to explain that you cannot bring your gun to the UK.

The American was persuaded not to fly to the UK, hire a car and drive 6 hours to the town where the meetings where. He might have been a lethal weapon. The American later admitted that NOT driving in the UK was a very good idea.

Techie banned from client site for outage he didn’t cause

Don't blame me - they virtually banned me

One of the service help desk came round to my desk, and said an important customers was blaming me on a major problem they had.

They had told their management, "we did xyz as expert abc said, and it caused this problem".

I looked into it.

The advice I had given was

If blah blah blah blah then do xyz. They ignored the if statement and did it anyway.

I had words with the salesperson who worked the account, who did some digging.

I offered a good will(free) call with the customer to discuss the problem and solutions.

The technical team had screwed up, and wanted to blame someone else, so they were definitely not keen on a call.

Help desk read irrelevant script, so techies found and fixed their own problem

ahh - that was embarassing

We had a big mainframe customer come to visit our lab, and discuss some problems they had with software that runs on many platforms.

One of the senior technical people, who develops on Windows, and had not used the mainframe said

Techie: "Change the config file, shut down your system down and restart it". That's what we tell our customers.

Customer: I dont think that will work, it will take about an hour to restart it

Techie: (very glibly) Well you should buy a faster box.

Customer: very, very, long pause

Customer: We have the fastest box. Our system come up in about 30 seconds. It takes an hour to check the connections to the 10,000 other system, and the 5000 database tables are all operational before we open it for business.

Techie : Ahhh. This was one of the situations where he wished he could just disappear.

Another long pause, before a senor managed stepped in to facilitate the discussion.

The techie was not involved with any future customer discussions

The Y2K bug delayed my honeymoon … by 17 years!

What goes up ... must come down

I had to fly to the US on Jan 2nd to support a very large customer in case they had any problems.

I heard people had been taken to hospital, because to celebrate the new century people fired their guns into the air.

What goes up... comes down, and there were a few cases of people being hit by the descending bullets

Whitehall rejects £1.8B digital ID price tag – but won't say what it will cost

Re: I can do it for half that

70 million records is small. I did some work for a Chinese bank - they had over 200 million personal bank accounts. You just need to use the right systems ( and do not expect to use a spread sheet or similar technology).

The problem is the non functional requirements. If you write an record audit every time someone's record is accesses - that will need a database 100 times the size of the number of accounts, and you keep this information for 10 years. And you'll need a fail over and DR system....

And don't forget field encryption etc.

Spec?

Spec ... they have a spec ? Wow - can we all see it - or is it just chartware?

Linux admin hated downtime so much he schlepped a live UPS during office move

High availability

I worked on IBM's mainframe systems, and a customer came to present about their systems.

He said "we have provided an uninterpreted service to our customers, front end and back end, for over 3 years"

We gave a smattering of applause.

He said "Wait ... I haven't given you the good story. We've done this, upgrading all of the software twice, and moved machine room twice"

That got a good round if applause.

He explained they moved some machines from one machine room to another, brought them up. The front end routers then directed work to these systems. The database could be morphed over in a similar way.

We were well impressed

Developer battled to write his own documentation, but lost the boss fight

Sometimes getting it right is important

After being plagued by having people who could not spell, one guy tried the following. At the end of the day instead to paying someone £30 pound, he gave them £3 pound. When they complained he said "well it says £3.00" here". He argued with them - and then gave them their £30.00 From then on, people were much more careful.

The usability seesaw

I worked on a large, very popular project. The installations documentation was 30 pages of instructions, then try to start it. It would often barf "ERROR IN $$BOPEN" and not tell you the file name.

For people who had never user it before this was very bad, as they had to start all over again. There were customer reported problems, which the pubs people tried to fix.

Experienced people would not have these problem because they just copied what they did last time, and changed a few names.

I rewrote this in baby steps. Do the following things, check it works. Do the next thing, check it works Do the next thing check it works - it doesn't? - well check the last thing you did.

A developer took this and improved it and we gave it to the pubs department, who made some changes and shipped it.

The response from customers was positive and the number of problems reported on installation went down significantly.

I changed projects. 5 years later I was asked to help a customer and found that the documentation had been "improved" by the new function owner who took out all of the baby steps and so the documentation was now 60 pages of instructions followed by "now try starting it".

I spoke to the new owner who said he thought that all the baby steps were unnecessary. He tested it every release - with the definitions he used the previous time. He had never started from scratch and type every thing in. And yes - there were lots of problems reported by customers.

It felt like a seesaw. Either make instructions clearer, but longer, or make then shorter and less clear.

The person who writes documentation needs to be empathatic - being able to put themselves in the position of someone who knows nothing.

Networking students need an explanation of the internet that can fit in their heads

Give the requirements

As well as the first statement, I would cover what people expect today.

Bits of the network will need to be replaced, for example your home router is connected to your service supplier. If they change their hardware, it should be transparent to you The "network" should carry on working.

You should not be impacted by other people. If the people next door are hammering the network, it should not affect you. If there is a lack of capacity they should be slowed down - not you.

When I stream my latest show - I expect it will display without hangs.

If you pay for a premium service, it should continue to work even if someone cuts an undersea cable.

Techie ran up $40,000 bill trying to download a driver

Dont hone home

I remember the days before WIFI when you had to connect your laptop to the phone cable. We had an AT&T dialer so we could phone a local number to get back to base.

It was someone's first trip abroad, to present a conference in a big hotel in the US.

Half an hour before his session he phoned home, got the demo working ... did his presentation working and did his demo. Round of applause - hurrah

His phone bill was bigger than than his travel. He had not used the dialer - so was charged at International rates for 90 minutes, with a hotel marlup of + 50 %

Delete is a two stage process

I learned early on that if you need to delete something. Rename it or move it. Then a week or so later delete it.

I learned this the hard way deleting a file. We easily recreated the file but is was missing some special attributes we hadn't noticed, and so it didnt work.

Great manager

I had spent a week at a banking customer abroad, and had a free day at the end before I flew home.

My phone rang at 0700 on Saturday, and my "boss" asked if I could help with a problem to which I said yes, and he gave me the contact number of the technical team. He said if I get unwanted calls phone him. If I need >anything< phone him.

I worked with the customer's teams agreed the problem and the plan to fix it. I told our boss what the plan was, and updated him as we completed each step.

I phoned him "we need access to ..." 2 minutes later we had access. "We needs someone to..." done.

All systems were back by 10am. I found that the bank had been down since 0400. The outage had the attention of senior managers (and the board). They had a plan for when this happened. One person would act as the focal point getting all the phone calls from people who cannot help. Only this person can phone the technical team.

It worked a treat - and let the technical folks handle the problem without the distracting chaff.

A great manager to work for. It was good we did not know the scale of the problem... we just got on and fixed the problem(s).

As we executed the plan my boss could tell interested parties the progress we were making, so everyone felt it was under control.

UK rethinks offshoring ban for £8M online procurement system

What does keeping this data in the UK mean

Does this mean

- all servers, are in the UK

- all backup systems are in the UK

- all data backups are in the UK

- all people who look at data - so any support people - are in the UK... so the data cannot be seen from India or Europe of America?

I worked in an international company, and we had 24* 7 support from people around the world.... I guess this will not be allowed.

The networking experts were in the US... they are not allowed to see the data.

UK's digital hospital plan meets analog reality check

"We want to be assured that no one will be left behind in this new online hospital," he said.

Don't hamstring them from day 1. Getting 10% using it - and finding the problems would be a major start.

It is not that the current system works. My aunt had to take two buses to get to and from a specialist hospital and it took all day.

After a week of this, my brother took time off work to take her ... and that was 3 hours round trip.

He would have been happier to take a laptop to my aunt, set it up for her, and leave her too it.

Word to the wise: Don't tell your IT manager they're not in Excel

Some managers are OK,

I was a new hire 40 years ago, and had been asked to copy some documents and do it duplex, so there was writing on both sides.

I printed the first page (10 times), then took the paper and put the paper back into the photocopier, and printed the next 10 pages. It was easy once you worked out which way the paper had to inserted.

My manager came to do some copying, and having watched me struggle - asked "Why don't you use the duplex button" ... which does this automatically. I remember this 40+ years later.

A long time later, when I had a not very good manager, he wanted some stuff copied urgently. I passed him at the copier, and he was saying "damn machine has a blockage... I'll go and find another copier".

I suggested it might be easier to unblock it, but he didn't know how. I opened the doors and written inside was "if this light is on - then pull lever 1, clear the blockage and then push level 1 back".

We followed the easy instructions and cleared the blockage. My manager was not keen on seeing the sheet which caused the blockage - but I could tell it was not work related.

As a so called "technical manager" he was not very technical - he thought we was very technical, and hated me showing him up.

Techie ended vendor/client blame game by treating managers like toddlers

Ping pointed the finger

I was involved in a set of long standing problems with a customer. We were a networking product, and the customer complained that periodically the throughput dropped almost to zero - and by the time they came to look at the problem it got better.

I think the customer found our support teams friendlier than their own support team.

I got them to have a simple program which every minute did a ping to the the remote end, and capture the response time.

They sent me the output, and I could see normally good response times with the occasional spike.

Our emails crossed mine said "did you have a problem at 0713" theirs said "we had another occurrence at 0713".

The customer asked me to present to their network support team, and it took about half an hour.

After we had finished we got push back from them "we do not see any errors/problems in our logs"

me: "What response times were you capturing for this time period"

tap tap tap.. "ahh we are just going on mute"

Eventually they said "we don't have any monitoring enabled on that part of the network" - which is why no errors were reported!

The networking people found the problem and the throughput problem was resolved.

The people I was working with still kept the ping every minute.

I was a part-time DBA. After this failover foul-up, they hired a full-time DBA

You should do this

I remember getting into trouble when the documentation said "you should do .... " when it meant "you must do...". The word 'should' implies recommendation but not mandatory.

Fortunately it was only a test system we could easily recreate. My supervisor got the documentation changed.

CIO made a dangerous mistake and ordered his security team to implement it

You are very brave

I had to visit a very large US customer about a problem on the mainframe. The team were depressed because the new big boss had told them to move off the mainframe on to commodity hardware. Commodity hardware means if you need more capacity you go down to your local Walmart and buy it. The big boss said it would save big bucks once the transition was done.

As part of my problem resolution I had to report to the upper management chain. I also spoke about my views on their change to commodity hardware.

I made comments like "you are very brave" (as in Yes Minister), and "I do not think you understand the capacity you need".

Someone kindly took me aside and explained how their estimates were right. They looked at the amount of traffic into the mainframe on the busiest day, and used that as their base line.

My comments like "on the mainframe 90% of the traffic between applications and the data base are cross memory and is not measured" fell on deaf ears. (Mouth engaged, brain in neutral, ears turned off)

They got a taste of things to come when they ran tests with live data and found the network could not cope, fixing the network then showed they didn't have enough commodity hardware.

Overall the project cost more than the mainframe - but they could not go back a) the mainframe people had all left, b) it would have embarrassed the people who wanted the new scheme. c) they would have all this kit they didn't need.

I used to meet up with someone at a conference, and hear all the news.

Basic projector repair job turns into armed encounter at secret bunker

How did you get in here?

This was a trip to a banks HQ - we were meant to be escorted at all times.

Our last day (after a couple of week visit) we could see the exterior badge locked door (for staff) was green - so we went in. We only had paper badges saying visitor.

We went to the secure inner sanctum, and the door was open because the cleaner needed the plug outside the room - to be able to clean inside the room.

We sat down and waited. Our contact came in and asked - "how did you get in here?" so we told him.

It turned out there had been a power blip somewhere - and the doors failed safe to unlocked.

They installed a "plug for cleaners" inside the inner sanctum.

A colleague in the US went to a secure underground nuclear bunker site for a briefing. He was accompanied everywhere at all times by an armed marine. When I say everywhere, the toilet cubicles did not have doors on them!

He said the whole experience was very scary.

I was once briefed by a man on security, who did not exist..... he said he worked for our company, but was not in the internal phone directory.

Why the UK public sector still creaks along on COBOL

Understand the problem - a little knowledge is a dangerous thing

I went to visit a US government establishment, to discuss some scenarios about the mainframe. They were not happy because the new boss person had been tasked with reducing the IT costs by 50% or more, and knew it could be done because he had set up a web server on his home Windows machine. He saw the solution was "to spin up utility hardware" (that is PCs you get from a PC store) when there was a demand for more capacity.

The IT guys I worked with did their own sums and said the amount of kit they would need would cost more than the existing mainframe - so no savings.

With the mainframe they had a down time of about 5 seconds of unavailability a year, processed 1000s of transactions a second and the response time was sub-second. They a backup site, and would regularly switch to it.

6 months later I got involved with a performance problem with the new environment. There were intermittent 10 seconds hangs many times a day and I could see it was a disk speed problem (in effect I had a trace of every I/O and about 10% had hundreds of milliseconds response time). The people who managed the virtualisation and disk farm said their stats were good.

I heard they solved their problems by doubling the size of disk farm, tripling the network capacity (to handle all the machine to machine communications), and disabling logging. At a huge $ cost.

I also know of another customer who moved from COBOL on CICS to Java on CICS (on the mainframe) for some parts of their business. They did a lot of planning and prep work - and the work came in on time - and budget. They started with a small, not critical piece, of code - and got that working - and learned many lessons from it. They then did a bigger project, applying the lessons learned etc, by the time they came to the critical code, they had a well established process.

It can be done.

Joke: How do you eat an elephant? A mouthful at a time. .... that applies to IT projects.

Can someone remind me ...

Can someone remind me ... Is it replace old systems with known bugs - with new systems with unknown bugs. Move fast and break things?

People often forget that the test suite is often larger than the "product" it tests. It has to do all the edge cases, performance, scalability, security, security validations (no you cannot have access) reporting, encryption of fields etc. The functions that "no one uses". A bank turned off a server which was "never used". It was used once a year at audit time for about 4 days.

If you go from screen scraping enter customer number in the first field of the old system, to its now the third field in the new system, this soon becomes a problem.

Dividing a system so you can isolate components, and have clean interfaces between components can make some of these transformations easier. Start by converting green screens to http and web pages ,so you can have named fields. This makes automation much easier.

Someone said that some of these projects are like trying to replace the engine of a jet - whilst in flight.

Whoops goes the EPO

Someone told me about a major outage caused by moving some disks. This was 30 years ago when disks were boxes 6 ft high and 3 ft square.

There was not quite enough space in the machine room for some new kit - it was a matter of inches too small.

No problem. Two of them put their backs against the problem disk, and having been on the lifting course, pushed with their legs.

It worked!

The problem was that one of the guys got his belt caught in the Emergency Power Off button (which you have to pull to activate).

As they stood up there was a sudden silence around them.

It took a good few hours to recover.

They had been proud of their system availability, and had charts on the wall. Their carelessness was on display for a year, until it rolled off.

You are a director ? Oh yes - there is a problem

We had a nice office with a great view, but the only problem was this was over an outside corridor. When it was cold outside we got cold feet, so we brought in insulation, and put a carpet on top. ( We did wonder why lowly minions were given such a nice office - every one else knew about the office). We complained to site services who said - there was not a problem - and we were wusses.

A director took over our office (and the ones next to it). The first cold day she complained the floor was cold - and whoosh site services were round "oh yes there is a problem". They found that water from the rain pipe from the roof was leaking into the space under the floor. When it was cold - it froze - and the cold flowed up to the floor.

It took them a few days to fix the leak - and a few months to replace all the insulation along the corridor - having to work from the outside.

Why are books organised by height or colour?

If you look at the fashion magazines showing how to furnish the room. The book shelves are always ordered, by height, or colour. (or an absence of books) These people clearly do not read their books.

Most people arrange them by author. I've got a row of books for an author by one publisher, plus another book in the series by a different publisher, which is a different size and colour scheme.

Whoops we forgot to state all the requirements up front - again

I remember "lessons learned" from several major projects which failed spectacularly. On of the common lessons was "understand and document the requirements before talking to vendors"

The requirements should be like "we want to ..." rather than "use this tool to..."

It sounds like the write back requirement was not documented.

Don't send data if no one is listening.

My company found that the external site that sent most data to our site was the local football team which was sending MB/second!

When you are looking at a site, it can send you data, such as a 5 seconds clip showing a goal being scored, or a ticker tape.

Normally the remote site only sends data when the web page is active.

Their web page did not have this, so if the web page was hidden by other pages, it still kept sending the 5 second clip of the goal being stored.

Many (hundreds) of people would check the web page first thing, while drinking their first coffee of the day, and leave the web page there.

This was pointed out to the foot ball team, and they fixed it - and were very grateful , because their traffic dropped by a factor of more than 1000, and they saved lots of money

'Trained monkey' from tech support saved know-it-all manager's mistake with a single keypress

"I'm not stupid you know"

One of my bosses was in tech sales before he became a manager. I worked on the mainframe down in the bowels with the really technical stuff.

With my managers I used to say "there is a problem with customer ABC it is really technical... so I wont explain it" - and most managers were happy.

This manager said "I was in tech sales - so I'm not stupid, please explain the problem".

So I did - there is a timing problem between this widget, and that widget resulting in.... I knew within seconds that he was totally lost, but he kept nodding.

After I finished he said immediately "I'd also like to talk to you about..."

I heard he asked one of my junior colleagues about the problem, and got the answer "you don't want to know ... it is deep shit that no one round here understands".

He continued to think I was deliberately making it complex to make him look stupid.

UK charity bank CAF branded a 'disaster' after platform migration goes wrong

"after years of planning, preparing, and testing"

It could be that they didn't actually know how the customers used the product.

With one product I was involved in, you could set a time out value tenths of a second. One customer used our product because the standard software only had a time out value in seconds!

They didn't use 80% of our product.

I remember going to customers and thinking "you are doing what! with it" - and going back to tell the test teams.

Junior sysadmin’s first lines of code set off alarms. His next lot crashed the company

and that's why they moved me to where I could do less harm

When I first worked nearly 50 years ago disk space was expensive, and I worked on DOS on the mainframe.

I was in the build group compiling a product. We had the build system and the live system.

I followed the instructions, deleted the old product, and started compiling the new code.

10 minutes later someone wandered round saying there was a problem.

I was working on the live system and not the build system.

My supervisor sorted out the problem and every one was happy.

They changed the instructions to say change this line.... to point to the build system.

Next week, I duly followed the new instructions and 10 minutes later someone came round...

I was building into the live system again.

My supervisor sorted it out - and changed the instructions to say "change >both< occurrences of..."

and that's one reason why I was moved to another platform with read only disks.

They also rewrote the instructions to include "what everyone knows".

Techie went home rather than fix mistake that caused a massive meltdown

metric/imperial

My father went to buy some timber.

Him:"I'd like a plank 6 ft long"

Them:"We are metric"

Him:" Ok I'll have a 2 meter plank"

Them:"We dont sell that size. We can let you have 1.8 meter plank" ( = 6ft)

The moon may not have been visible at that time.

We also have collaboration between US and Europe. I think there was one space shuttle mission looking for a mountain 4200 m high. So instead of looking for Hawaii (4200 meters high) - it turned towards the sun .. the closes thing to 4200 mile high.

Re: Honestly I'm bilingual

Ladies and gentlemen - this is your captain speaking. We will be flying at 40,000 ft at 1000 km per hour.

It's hot today - it is in the 20s...do you remember it being in the 80s when you were young.

I don't want plans I want results

I was involved (on the perifery) of a project to save money on a project. It was announced to everyone so we were all "part of it". Teams to produce plans.

The manager I was working with, called a meeting, and said "I don't want plans... I want actuals". We met up again a week later and had results like

1) because I always had to approve xyz - Ive set up a script to logon once a day and do it

2) we have all these old copies of software on disk - which we think no one wants. We've archived them to tape and freed up xGB of disk space

3) We don't think anyone uses these servers. We've powered them off. We can easily power them on again if anyone complains. We can virtualise them if needed.

All small stuff - but the first steps are the hardest.

A month after the big announcement the senior manager calling for the project to save money, asked for a review on progress so far.

Departments put up nicely written presentations about what they could do. etc

My manager put up one chart with the above points and said ( verbatim ish - it took less than 2 minutes)

- these are actuals. We are not doing any planning

- in any status meeting - people are allowed at most 1 chart

- the meetings now run to time

- we all go for coffee at 1000 - and raise any issues then - saving half an hour a day * 10 people

The senior manager took the hint and realised how much time (and cost) had been wasted doing blue sky thinking, and preparing charts etc.

He gave some ground rules

- No more overtime. Schedule your work better - or ask for help.

- I want to hear about meetings which are a waste of time

- Simple charts

- Get to know people in other areas who may be able to help you ( no more silos)

- I will be walking around the building - if you see me - tell me something (good or bad)

As a result meetings shrank (they had meetings but with 3 people not 13) and they found lots of overlap and so could save duplication.

Simple stuff but it worked.

Techie traveled 4 hours to fix software that worked perfectly until a new hire used it

Insanity

"the definition of insanity is doing the same thing again and again and expecting a different outcome"

Sometimes I do something every day, and it works. Every now and again - it does something different.

And the opposite. Something is broken, so I start to debug it - and now it works.

Timing problems are a curse.
