Man people keep count of this stuff?! Maybe I should too, it does make flexing easier.

brendangregg2 months ago

I like to measure things. In real life and on computers. But I also have a couple of work reasons for it:

As a remote worker, I'm under extra pressure to prove that remoteness works.

As a senior employee, I'm also under pressure to regularly report where my time is spent.

raw_anon_11112 months ago

As a senior employee. This is just the opposite of what I would expect.

(I’m not the author of this)

https://news.ycombinator.com/item?id=46146451

As a senior employee first at a startup from 2018-2020 and then as a staff engineer at a consulting company for the last year (with a 4 year at BigTech detour between), no one really micromanages me.

Even at the consulting company, when I am on a project, I just put 40 hours in Salesforce with the project I’m assigned to - with no details - or put “bench” - again with no details.

Why would my company care? The customer is happy, the project is managed through Jira (where I as the lead create the tasks) and my company gets paid when the project is done.

I am sure I ask for feedback after every project in our peer review system.

spjt2 months ago

In my experience, having to track my hours absolutely destroys my performance. Thinking about how I need to pay attention to how long I spend on everything is a constant distraction in the back of my head while I try to do anything useful, and then I spend the rest of the day procrastinating having to fill out the paperwork. I know I'm not the only one because the entire dev staff was ready to mutiny the last time I was at a company that tried to get devs to start tracking their hours.

In my experience "just put 40 hours in Salesforce with the project I’m assigned to" matches folks expectations.

However.

If you're ever on a project that doesn't turn out so well, it may suddenly become critical to account for all work done during every billed hour in detail.

I would advise all consultants to track their time diligently and completely.

raw_anon_11112 months ago

That’s part of the project management tracking but that’s not strictly hours.

Those traceability artifacts are in order

1. the signed statement of work - this is the contract that is legally binding.

2. The project kick off meeting where we agree on the mechanics of the project and a high level understanding of the expectations

3. Recorded, transcribed and these days using Gong to summarize the meetings, deep dive discovery sessions.

4. A video recorded approvals of the design proposals as I am walking through it.

5. A shared Jira backlog that I create and walk through them with it throughout the project

6. A shared decision log recording what decisions were made and who on the client side made them.

7. A handoff - also video recorded where the client says they are good going forward.

I lead 2-7 or do it all myself depending on the size of the project.

At no point am I going to say or expect anyone on my project to say they spent 4 hours on Tuesday writing Terraform.

But then again, my number one rule about consulting that I refuse to break is that I don’t do staff augmentation. I want to work on a contract with requirements and a “definition of done”. I control the execution of the project and the “how” within limits.

I want to be judged on outcomes not how many jira tickets I closed.

When I was at AWS I worked with a client that directly hired a former laid off ProServe L6 consultant. He was very much forced into staff augmentation where he did have to track everything he did by the hour.

You could tell he thought that was the fifth level of hell going from strategy consulting to staff augmentation. It paid decently. But he was definitely looking and I recommended him as a staff consultant at my current company (full time direct hire)

FWIW: I specialize in cloud + app dev - “application modernization”

Yeah, it's how everywhere is measured. But I like to remember Joel Spolsky's takes on measuring everything, including his famous book and blog:

graemep2 months ago

Contrary to the usual opinion on HN, this provides a good reason to do an MBA!

You should learn enough economics that if you are even a bit insightful you will avoid Econ 101 thinking, you will learn about things like intrinsic and extrinsic motivation, and a lot of other things relevant to management.

dh20222 months ago

My MBA program mentioned in passing intrinsic / extrinsic motivation in the Ethics class - which in my program did not even have a final exam :).

Most of the time was spent on cost cutting, customer vs producer surplus, profit margins, efficient markets theory, lots marketing, lots of "the purpose of a commercial enterprise is to make money for its owner" said in different ways, and maybe some operations analysis.

jama2112 months ago

kmarc2 months ago

Damned is this industry, when even _you_ say you have to show that "remoteness works".

I also measure meetings (counts, lengths, and mostly meeting minutes/outine jotted down by myself) and keep track of other metrics, exactly for this reason. However, I also don't happen to have written best selling books and stuff, so I really must do this, and you really shouldn't have to :-)

pm902 months ago

I have more respect for him because he chose to do this. It’s probably clear that he doesn’t have to, at all. But he’s choosing not to rely on his (somewhat) tech celebrity status and deliver on measurable outcomes.

Not that I've ever been especially religious about it but it's probably a good thing to keep track of activities, especially those that directly affect customers. It's pretty easy/low-effort and is useful to be able to pull out.

It doesn't need to prove that. It needs to produce plausible data that appeases either your direct or +1 manager.

boringg2 months ago

Do you have a particularly easy way to track or are you kind of doing the same thing as consultant and logging your dailies? Always drove me a bit crazy having to do that admin piece every day.

rjzzleep2 months ago

If only I had known that in the past, I even once received the completely wrong advice to "not stand out, since your work will speak for itself and you will get recognition".

pas2 months ago

It depends on the company culture.

(Fancy US tech companies like to be very selective, have a competitive mindset, hire "the best" according to their filters, and then want people to show how amazing they are, uu, so much impact, woah... and in effect people need to constantly manage upwards.

While in many other companies, or "orgs", having a good team cohesion is more important. To blend in a bit, get accepted even if it means foregoing some ambition.)

That said it's always good to have receipts.

raw_anon_11112 months ago

Having good team cohesion is all well and good. But when it’s time to get promoted, what are you going to say “I pulled well defined Jira tickets off the board”?

When you get ready to interview for your n+1 job, and you spent months grinding leetCode and practicing reversing a btree on the white board, get to the behavioral interview and I ask “what accomplishment are you most proud of?”, what are you going to say “I worked with my team and we together closed 20 story points a week”?

I have given the thumbs down to a lot of candidates this year alone who couldn’t discuss something that they took ownership of or where they stood out.

auggierose2 months ago

taurath2 months ago

It’s more that it takes so long to get anything done, the effort and results need to be recorded because it most often won’t be obvious from the impact. It’s hard to make a splash on a production system maintained by 30 other people, but you can usually make things better, but it won’t always be obvious.

I guess they don’t know how or don’t bother to evaluate people on what they actually contribute? Just number of meetings attended, number of tickets closed?

izacus2 months ago

Those meetings were the authors actual contributions. Any really senior person isn't going to be coding.

jackling2 months ago

Meetings by themselves are worthless. Similar to how having an idea for something isn't intrinsically valuable. I argue, meetings can't be actual contributions because the real state, the code/hardware/etc, of your project hasn't change. The result of the meeting, what people actually do afterwards due to what was discussed, is all that matters. In which case, it isn't the meeting that was the contribution, it was the artifacts that were created afterwards (documents, jira project tasks, code, etc) that are the contribution.

When we view meetings as actual contribution, we're really just valuing people doing effectively nothing. For example, anyone who's job is just to take meetings, and nothing else, is worthless IMO. You need to tangibly create something afterwards. This is a problem with big tech (which the company I work for is one of), it rewards people shuffling papers around, especially senior+ engineers, instead of valuing real work they should be doing.

Senior+ engineers have also deluded themselves into thinking that they shouldn't be coding, and rather their real work is creating endless amount of superfluous documents and creating as many cross team meetings as possible, rather than doing the hard work of creating an actual product.

Arainach2 months ago

What does "actually contributed" mean?

Joe implemented feature A. Sandra implemented feature B. Raj implemented C. All launched in July. Since then metric X is up 20%. Who gets credit, and what does that credit really mean?

Now say all 3 did that in 3 different products. One produced a 200% improvement in an internal product, one a 40% improvement in a product with thousands of users, one a 1% improvement in a product with a billion users? Compare *that*.

I know some of them do this, but ours doesn't. There is a once yearly self-review, and as far as I can tell it has literally no impact on your actual performance review and compensation, which are basically entirely up to your manager's observations of you.

So it is important to keep your manager informally up to date on what you're doing, at least during the weeks they're thinking about performance.

Sometimes it's very telling what people think are accomplishments.

raw_anon_11112 months ago

While I have a personal career document and have had one for years where I have all of my major accomplishments in STAR format. This seems a bit much.

When I was at BigTech, there was an internal system where you recorded your major accomplishments and the impact they had.

But I would never write it up on a public blog post like this. I am assuming the author of the post must be someone well known in the industry for it to make it to the front page of Hacker News. If his intent was to promote himself so he could get another job, I’m sure that he has a network where a few messages would lead him to one.

Even in my little niche of the world where in the grand scheme of things I’m a nobody, I was able to lean on my network at 50 after being Amazoned in 2023 and have three offers that were at least a lateral move within two weeks.

I had one fall into my lap last year too that I accepted based on my network.

In my world it's hard to imagine an impact after that short of a time. And in fact, reading the list of accomplishments ("interviewed by the Wall Street Journal") makes it clear it's a good PR piece.

komali22 months ago

Clicking through his links to various posts about e.g. stack pointers or flame graphs, my takeaway is he's an outlier in productivity, and got a lot done in 3.5 years at a monstrously large organization.

Flamegraph is literally just a perl script that visualizes the stack traces collected by perf/dtrace (kernel). It's a good tool though but it doesn't need to be oversold for its capabilities, the hard work is done by the kernel. And honestly, many times it is not that useful at all and can be quite misleading, and not because of the bug in the tool but because how CPUs are inherently designed to work.

tclancy2 months ago

Everything is just a script with some visualization once you come up with the concept.

I was there for 21 years, this guy is symptom of a much larger problem that is self-sustaining.

solatic2 months ago

This was the takeaway I had taking to a colleague about his time at Intel - they're a genuinely global company with engineering teams in practically all time zones who are still expected to collaborate with each other. No matter what time of day the meeting was scheduled for, it was the middle of the night for somebody, and no, just working on written docs async for everything didn't cut it, and they couldn't just fly people out all the time. So that's apparently just part of what it means to take a job at Intel these days.

Those 1-6am meetings are crazy. I’ve been fully remote for over 16 years now and my only 1-6am meetings are incident response, if I’m on call.

torginus2 months ago

I think this is a good opportunity to guerilla-ask a question about cloud performance:

We've been running some compute heavy workloads on AWS, with some running on metal instances, and some running on virtualized instances of equal size.

Both were intel 192 core machines.

Virtualized instances tended to perform 20-25% worse in terms of CPU throughput, which is quite significant, and more than I'd have assumed.

Where does the performance go? Is this an AWS thing, does the performance get lost in the software stack, or is it a CPU-level issue?

I haven't tried with other vendors tbh, but would it be possible to mitigate this by switching to another architecture/vendor like AMD or Graviton?

everfrustrated2 months ago

On modern AWS instance types so much is offloaded to dedicated hardware that the only shared (noisy) components between VMs is memory bandwidth and higher levels of CPU cache (and I think graviton doesn't even share CPU cache now)

I would suspect your performance difference is mostly likely showing that on metal you are sharing the same software wider so not polluting caches as much as a vm neighbour running unrelated software.

torginus2 months ago

The virtual instance is the exact same size as the metal one, which covers an entire physical machine - I guess this is pure overhead rather than noisy neighbors.

arcanus2 months ago

That's a surprisingly large overhead. I've not measured that large an impact on AMD, particularly for compute heavy.

Did you profile at all? And have you observed if it's not compute-bound? If it's memory or IO bound it can be due to other virtualization overheads, such as memory encryption.

torginus2 months ago

I will try to profile, but how do you suggest going about it, what to measure? Maybe running some synthethics stressing CPU or memory?

The workload is pure memory/CPU, with very little IO so it's 100% compute bound, with much more emphasis on CPU.

There's a lot of I/O hidden in CPU-bound loads related to fetching, prefetching, caching, etc.

Where do you think he's going next? OpenAI? Google? Just saving 1% on inference could probably justify his salary 100fold

anonymoushn2 months ago

This is true economically but in reality if you have much larger cost savings than that for sale then these companies mostly say "we would be happy to buy that for $0 while we pay you a million a year to move to the united states"

boguscoder2 months ago

Not being sarcastic here, a million a year is not a target compensation for engineer like him, 5-7 is probably where it starts and goes to the stars

Definitely feels like someplace with GPUs that will let him work remotely.

I'm guessing he'll land at one of the big frontier model companies. I'm surprised he stayed at Intel as long as he did, they are dying fast.

bigiain2 months ago

And it seems there's only one of them that's gonna have any new hardware that needs GPU flamegraphs to optimise...

AMD, Apple, or NVIDIA?

Or Amazon, Google, Cerberus?

Do _any_ of those six companies have any guarantee of silicon wafer supply over the next 18-24 months?

I’m wonder how much longer Intel will be around. It seems to be dying a slow death like Kodak or IBM at this point.

"death" can be pretty slow - IBM has $60B in revenue and 270K employees.

When Shakespeare wrote "cowards die many times before their deaths", he had Intel in mind.

I really have no idea how IBM is still in business, or the other big toxic techs like Oracle and Salesforce. Just goes to show I don’t know as much about the industry as I think.

zipy1242 months ago

Oracle basically runs HR and finance services for like every large company in Europe. They also run a scary amount of healthcare stuff and other government tech type stuff.

It sucks but I see why they do it. If you don't have the technical/managerial talent to handle procurement then it's the safest bet.

They bought Red Hat, which has OpenShift and all their other "DIY Cloud" bits. This stuff is popular in government or old businesses that may have been slow to (or unable to for regulatory reasons) jump to AWS/GCP etc.

To say nothing of the banks and others still using the IBM big iron.

they’ve been partnering with nvidia to build large ML training clusters iirc last time i was in their building at a meetup a few weeks ago

toast02 months ago

IBM still sells mainframes and similar. And has a giant consulting and service business.

Their purchse of RedHat flows into consulting. Their purchase of Softlayer (rebranded into IBM Cloud) is more IBM owned, customer operated computing, a business IBM has been in since forever.

And their financial/stock performance has been pretty good the past couple of years.

The government took an ownership stake in the company. Nvidia invested a few billion in the company. It's not going anywhere.

Intel is going nowhere.

They are a gov chosen winner, so it is a safe bet they will exist for as long as they are a useful political puppet. Why or how would they become more competitive?

Lindy[1] will make sure it stays around for a while.

Although you're correct that it would be too soon to prophesize their death, I want to clarify that Lindy ensures correlation, not causation.

Intel still sells a ton of silicon.

In the photo of him on his last day [0], there's a cassette deck on his desk.

That could be something mundane, but I'd like to believe something crazy happens if you yell at it [1]...

Looks like the C64 is behind it (underneath a..?) and there’s a small corner of 5.25” diskette station further back.

Probably not his daily drivers.. :)

Keyframe2 months ago

Yeah, behind datasette it looks like there's C64 C parked, and above is a laser 300 (which makes sense if guy is australian) and we can also see 1541-ii behind that, on the top.

I mean I understand if someone like Keller writes such posts but some dude claiming to have hosted conference events and some kind of process flame graph which could have been done by anyone…

Maybe you should read something about him before you call him that. I recommend the "Contributions"-section on his Wikipedia-article. And if it is of any relevance to your work: his "Systems Performance: Enterprise and the Cloud" is a comprehensive and excellent guide.

Read this blog post from the same author https://www.brendangregg.com/blog/2025-11-22/intel-is-listen.... I'm surprised that this narcissist Fellow wasn't shown the door by the company for 3.5 years.

Good luck to whichever team he now joins and get ready to be shoved with his accomplishments reports.
