Tryception

by in CodeSOD on

"If at first you don't succeed, try, try again."

We have all encountered situations where we need to attempt an operation, with full knowledge that the operation might very well fail. And if it does, we should retry it. Usually after a delay, usually with a maximum number of retries.


A Profitable Education

by in CodeSOD on

Today’s anonymous submitter is an experienced Python developer. Their team is significantly less experienced. In the interests of training, someone suggested, “Perhaps we should buy books for everyone.” Our submitter was handed a stack of possible books, and asked to pick the best one to help the team mature.

One book spent some time discussing types, and the conversion between them. By way of example, it provided a handy method which would turn a string into a floating point number:


An Equal Crunch

by in Representative Line on

Rina works in an environment which tends to favor crunch. It's a bit of a feast or famine situation, where they'll coast for months on a pretty standard 9-5 schedule, and then bam, suddenly it's 18 hours days.

No one particularly likes those periods, and code quality takes a nosedive. Co-worker Rusty, though, starts making utterly bizarre decisions when stressed, which is how Rina found this line while doing a code review:


To Round a Corner

Last week we saw an attempt to reinvent the ceil function. Tina raised a protest: "6 lines to re-implement a ceil function? We can do better."

//Rounds to 1000d Superior public int round1000dSup(int value_To_Round) { int finalResult = 0; int resultIntermediate = value_To_Round / 1000; resultIntermediate += 1; int valueRounded = resultIntermediate * 1000; if ((valueRounded - value_To_Round) == 1000) { finalResult = value_To_Round; } else { finalResult = valueRounded; } return finalResult; }

A Swift Update

by in CodeSOD on

Banks are uniquely identified via a “SWIFT Code”. It’s an ISO Standard. Having an accurate SWIFT code for a given bank is of vital importance to anyone doing financial transactions. With mergers, moves, new branches, and so on, the SWIFT codes you do business with won’t change often, but they will change.

Thus, Philip wasn’t terribly surprised when he got a request to update a pile of SWIFT codes. He couldn’t make the change via the database, though, as no one had permission to do that. He couldn’t edit it through an application UI, because no one had ever built one.


Hitting Your Skill Ceiling

by in CodeSOD on

Clia was handed a pile of legacy code and told to upgrade it, but with a very important rule attached: the functionality couldn't change. Any change could break someone's workflow, and thus in the upgraded system, even the bugs had to be reproduced.

Unlike most "legacy" code, this wasn't all that old- it was written in C#. Then again, C# is old enough to drive, so maybe it is old. Regardless, C# has utility methods, like, say, a ceil function. At no point in C#'s history has it lacked this basic functionality.
