is that through a pull request?

user41796

<--- Does only TFS for a reason...

Robert Harvey

No, just a pull. (apparently there's a difference).

Or a sync.

I can't push my commit because there are conflicts, I can't get their changes because there are conflicts, and I can't do a revert because I have uncommitted changes.

Usually I get a link to some place that shows me the merge conflicts, but I'm not getting that this time.

user114359

Commit = send changes to your local repo
Push = send changes in your local repo to the remote
Pull = someone grabs your changes from remote into their master repo that you cloned to begin with

Robert Harvey

Oh, OK.

user114359

You will probably need to sync the changes from the remote that someone else owns into your repo first

git can be confusing this way because there are extra repos sitting around that don't exist in most corporate environments

Robert Harvey

I guess I have some new changes after the commit. But I don't know where all those are.

My cohort says he does merges manually, outside of the environment, using a diff tool. I told him that did not appeal to me at all.

user114359

If your changes are simple enough (e.g. adding new files) it might be easier to blow away your repos, re-clone, and start over. If your dev environment can make a patch easily (Eclipse can, for example) it is a little tedious but pretty simple

user41796

@RobertHarvey That should be a last resort option

user114359

I definitely prefer to use an IDE for this most of the time. Sometimes I do use WinMerge because it can handle directory merges fairly efficiently

Robert Harvey

@Snowman I think that's what I'll do.

user114359

5:06 PM

For example, if you have 5,000 files scattered in hundreds of directories

Robert Harvey

The Git/TFS workflow seems terrible. Perhaps I just don't understand it.

The build workflow is equally bad.

user41796

@RobertHarvey It's not the first combination I would have thunk up

Robert Harvey

You said "TFS only." Did you really mean TFS/VSS?

Because my understanding is that TFS doesn't actually have a source code provider native.

You have to specify one.

user41796

@RobertHarvey That's not my understanding of it, but I didn't do our install

user41796

I think we started with TFS 2010 which evolved from VSS, but is a separate product

Robert Harvey

5:15 PM

I think we're going to need a meeting to discuss the workflow. Because my philosophy is "push early, push often." My teammate wants me to wait until a feature is done. Both of us are just pushing the pain to the other person.

user114359

@RobertHarvey that's the beauty of git, though. You can do both, and both are appropriate. Commit often to local, squash into single features for pull requests.

Q: Why squash git commits for pull requests?

Why does every serious Github repo I do pull requests for want me to squash my commits into a single commit? I thought the git log was there so you could inspect all your history and see exactly what changes happened where, but squashing it pulls it out of the history and lumps it all into one c...

user114359

The accepted answer explains the process very well.

Robert Harvey

More command line stuff. You'd think Microsoft would have figured all of this out in the UI. Maybe they have, and I just don't understand it yet, but I get the distinct impression that this whole GIT in TFS thing is very new.

Thanks for that, BTW.

I don't know anything about TFS or MS SCM/build processes in general. I am only speaking to the git workflow

Robert Harvey

@subhash: My theory is that its' a subtle form of age discrimination. Companies ask questions like that in interviews because they know that the ones most likely to answer them correctly are the ones that just got out of uni. — Robert Harvey ♦ 6 secs ago

> However I feel no problem because of this in software development in web and android because we hardly use data structure there.

user114359

The question is flawed to begin with

user114359

Every program uses data structures. At the very least, there are stack frames.

user114359

The process space itself is a data structure

Robert Harvey

5:30 PM

The kinds of interview questions I'm talking about are the ones like "how do you calculate the width of a binary tree?" Something you'd never have to do in a real job.

or "How do you reverse a string in O(1) time?"

Jimmy Hoffa

@RobertHarvey you turn into Kirby and stand on your head?

user114359

I never did like the programming puzzles to weed people out. Better to give a simple problem and ask for a design, maybe some high-level code

Jimmy Hoffa

@Snowman I like both implementation and high level - just give them an hour to write some code for some random thing and see what they come up with - that they can actually code. Then talk high level stuff. But yeah, those trivia Qs are blech.

Though what do I know, I can't pass any of those so..

Thomas Owens

@RobertHarvey Oh, you mean Google interview questions?

user114359

there is also the good old fashioned fizz-buzz. Quite simple, yet very effective at weeding out candidates.

Robert Harvey

5:35 PM

@ThomasOwens Anything lifted from Geeksforgeeks.

or Hackerrank.

And yes, Google interview questions qualify.

(Not the "how many jelly beans can you put in a bus" variety).

@MichaelT I get no people if I search voters/week

Jimmy Hoffa

@Snowman recently we interviewed a senior with 20 years of experience, when asked by prepared statements are important he didn't mention SQL injection, then when pressed on "security reasons" a little more he thought then said "Oh yeah! Cross site scripting attacks!"

facepalm

user114359

@JimmyHoffa 20 years of experience doing what? Probably not programming.

user114359

@enderland you probably need to wait for midnight UTC

user41796

@JimmyHoffa My first thought would have been because of performance / optimization routines

Jimmy Hoffa

5:38 PM

@Snowman Java. His resume read great... everything from junior up through senior, architect, and CTO. Last couple years as senior. He was ex-sun.

Thomas Owens

@JimmyHoffa Bleh.

Jimmy Hoffa

@GlenH7 it was in reference to java where "prepared statement" means what we call in ADO.NET a Command

user114359

docs.oracle.com/javase/8/docs/api/java/sql/…

Jimmy Hoffa

not the same as stored procedure - just the ODBC command

user114359

PreparedStatement may improve performance. It also allows parameter binding, which practically eliminates all SQL injection attacks.

user41796

5:40 PM

java is tripping me up today. Clearly I need more coffee

Jimmy Hoffa

@Snowman yeah - which is the main reason. I mean, performance wise it's not expensive to create one I would figure no? So recreating them may not be a big deal. Either way, not knowing commands are a necessity over string concatenation because SQL injection is just...

Though I don't know Java, preparedstatements may be very expensive

enderland

@JimmyHoffa never happened to me in 20 years, not a big deal

user114359

@JimmyHoffa technically it is an interface, the details are driver-specific. Generally they are no slower than regular statements, and typically faster if reused. However, I have heard that many modern drivers use the same implementation under the covers for Statement, CallableStatement, and PreparedStatement.

Jimmy Hoffa

in any event. Point is, it's surprising how easily lots of people are tripped up even when they apparently have long successful careers..

A: Why is "final" not allowed in Java 8 interface methods?

This question is, to some degree, related to What is the reason why “synchronized” is not allowed in Java 8 interface methods? The key thing to understand about default methods is that the primary design goal is interface evolution, not "turn interfaces into (mediocre) traits". While there's so...

There's a lot of subject matter out there to trip over

user41796

Depends upon what his background was in

flipside, how did he do on the other questions you had?
