ern··on What's Happening to Students?
I remember watching hours of TV as a child in the 80s. I remember my cousins, born in the 90s staring like zombies at Cartoon Network when they were toddlers. We're all reasonably functional adults (most high achievers academically, and holding down well-paid jobs, with families). We also had huge amounts of screen time playing games, mostly on PCs.

If screens per-se are the problem, we'd have seen the same issues manifesting decades ago.

I think phones are the issue, rather than screens, specifically social media and notifications in particular. Someone suggested turning notifications off for social media, and it was a big change in my life, and something I've urged my own children to do as well.

ern··on The Alexa feature "do not send voice recordings" you enabled no longer available
Weird that this got downvoted, considering that Amazon is currently rolling out Alexa+.
ern··on Are electric cars that much cheaper to operate?
Depends on the country. Outside of North America, 240v is L1.
ern··on Are electric cars that much cheaper to operate?
I have a 240v wall outlet that charges at 1.5kW and it's more than adequate 95%+ of the time.
ern··on Chat is a bad UI pattern for development tools
I had the same feeling reading this, but a large number of developers struggle to communicate verbally and would hate a chat based interface. Some years ago, I worked with a very intelligent person who had come into development with math-related degree.

We tried a pair-programming exercise, and he got visibly angry, flustered and frustrated when he tried to verbalize what he was doing.

One of the reasons Business Analysts and the like exist is that not everyone can bridge the gap between the messy, verbal real world, and the precision demanded by programming languages.

ern··on OpenAI O3-Mini
I haven’t bothered with o3 mini, because who wants an “inferior” product? I was using 4o as a “smarter Google” until DeepSeek appeared (although its web search is being hammered now and I’m just using Google ).

o1 seems to have been neutered in the last week lots of disclaimers and butt-covering in its responses.

I also had an annoying discussion with o1 about the DC plane crash..it doesn’t have web access and its cutoff is 2024, so I don’t expect it know about the crash. However, after saying such an event is extremely unlikely and being almost patronisingly reassuring, it treated pasted news articles and links (which to be sure, it can’t access) as “fictionalized”, instead of acknowledging its own cut-off date, and that it could have been wrong. In contrast DeepSeek (with web search turned off) was less dismissive of the risks in DC airspace, and more aware of its own knowledge cut-off.

Coupled with the limited number of o1 responses for ChatGPT Plus, I’ve cancelled my subscription for now.

ern··on Why OpenAI's $157B valuation misreads AI's future (Oct 2024)
ChatGPT Plus gives me a limited number of o1 calls and o1 doesn't have web access, so I mostly have been using 4o in the last month and supplementing it with DeepSeek in the last week, for when I need advanced reasoning (with web search in DeepSeek as a bonus).

The killer app had better start giving better value, or I'd gladly pay the same amount of DeepSeek for unlimited access if they decided to charge.

ern··on I trusted an LLM, now I'm on day 4 of an afternoon project
I had a couple of the most capable senior developers reach out to me to tell me how Github Copilot accelerated their productivity, which surprised me initially. So I think there's something to it.
ern··on Time for a code-yellow?: A blunt instrument that works
I think the problem is a bit harder than that. I've seen a lot of managers who were once technical, but whose last hands-on experience was years, or decades ago. They have a vague idea of what they need to know/do but lack the skills to find things out themselves. and they turn into a major drag on productivity.
ern··on Does Your Code Pass the Turkey Test? (2008)
OT: I like how he refers to a Hanselman post about great interview questions, and how around 40% of the questions in that post are obsolete. It shows how quickly our field evolves, for better or worse.
ern··on Facebook's Little Red Book
There was plenty of cynicism in tech back then too, plenty of posters who always complained about 'micro$oft'.

I think the anti-Microsoft sentiment (outside of some internet forums, and justified IE6 hate) had been dialled back by the early 2010s.

.NET was a thing, they were post-Gates, post-antitrust, making significant efforts at developer outreach. Windows 7 was a hit.

Despite working in the Microsoft ecosystem, I didn't feel trapped, and the walled garden was coming down, with awareness of non-Microsoft technologies being widespread.

ern··on Australian Parliament bans social media for under-16s
He lost a lot of seats in the 1998 election and suffered a big swing against him.
ern··on Australian Parliament bans social media for under-16s
It’s not polarised, but it is quite sclerotic.
ern··on Australian Parliament bans social media for under-16s
Compulsory voting means that a large part of the electorate that doesn’t pay attention to politics is easily frightened by scare campaigns.

An example of this is that Australia is sorely in need of tax reform, but any party that pushes for it at state or federal level is damaged at the polls, often fatally.

ern··on LLMs have reached a point of diminishing returns
Something interesting I observed after introducing LLMs to my team is that the most experienced team members reached out to me spontaneously to say it boosted their productivity (although when I asked other team members, every single one was using LLMS).

My current feeling is that LLMs great with dealing with known unknowns. You know what you want, but don’t know how to do it, or it’s too tedious to do yourself.

ern··on Gettiers in software engineering (2019)
Would a merge instead of a rebase have made it easier to find the bug? (Serious question)
ern··on A subtle change to the iPhone’s contact-sharing permissions
LinkedIn provides no mechanism to hide your profile from other members by default apart from an explicit block.

I was stalked on it by an unhinged bank employee, and even though he's blocked I still see people from his company have viewed my profile on a regular basis.

ern··on AI agents invade observability: snake oil or the future of SRE?
Even then, most of these coding tools aren't even close to automating meaningful coding tasks in practice, and while that doesn't mean they can't in the future, it's a long ways off!

Not related to your main point, but I've introduced Github Copilot to my teams, and, surprisingly, two of our strongest developers reached out to me independently, and told me it's been a huge boost to their productivity, one in refactoring legacy code, and another in writing some non-trivial components. I thought the primary use would be as a crutch for less capable developers, so I was surprised by this.

As a middle-manager whose day job previously robbed me of the opportunity to write code, I've used ChatGPT 4o to write complex log queries on legacy systems that would have been nearly impossible for me to do otherwise (and would have taken a lot of effort from my teams) and to turn out small (but meaningful) tasks, including learning Android dev from scratch to unblock another group and other worthwhile things that keep my team from being distracted and able to deliver.

I guess there's a "no true Scotsman" fallacy hiding there, about what constitutes "meaningful coding tasks in practice", but to me, investing in these tools has been money well spent.

ern··on How to Lead Your Team When the House Is on Fire
I really don't understand the hate for Agile. Adaptation, empiricism, iteration self-managed teams etc...what's not to like?

I'm currently involved with two programs run by project managers who probably haven't written code for 30 years (if ever), and it's a nightmare.

ern··on Why Scrum is stressing you out
I’m not sure why the above comment is being downvoted:

I was reading The Practice of Cloud System Administration: Designing and Operating Large Distributed Systems, and I came across this quote:

Royce’s 1970 paper, which is credited with “inventing” the model, actually identifies it so Royce can criticize it and suggest improvements. He wrote it is “risky and invites failure” because “design iterations are never confined to the successive step.” What Royce suggests as an alternative is similar to what we now call Agile. Sadly, multiple generations of software developers have had to suffer through waterfall projects thanks to people who, we can only assume, didn’t read the entire paper (Pfeiffer 2012) [p. 175].

ern··on iPhone 16 Pro and iPhone 16 Pro Max
I pay very little attention to features on phones, especially things like improved cameras, but I finally upgraded my iPhone X to an iPhone 15 (one of my kids needed a phone). I've noticed that I've been able to take some stunning pictures out of planes when flying, as well as low-light photos.

I agree that even when they aren't explicitly highlighted, they do make a substantial difference, especially when comparing models over a span of a few years.

ern··on Kids who use ChatGPT as a study assistant do worse on tests
I use ChatGPT 4o to check my child's homework, but I forbid them from using it directly. That way, I can make sure the work is correct (or at least wrong in the same way as ChatGPT) without straining my tired brain.
ern··on Australian employees now have the right to ignore work emails, calls after hours
Startups, and anyone else can still roster support.
ern··on CEOs are running companies from afar even as workers return to office
I think the introduction of WFH during the pandemic hurt a lot of IT workers in the long-run.

In the interests of “fairness” they are being ordered back to the office post-Covid even when their work processes mean they can be done perfectly well remotely, and even if they have widely geographically-distributed teams.

Anecdotal, but we had a team that was split with 50% working remotely before Covid, and we saw an improvement when everyone was forced to work remotely: conversations that were being held in person were shared openly.

ern··on Alexa is in millions of households and Amazon is losing billions
I would consider using Alexa to buy things if it understood what I wanted. It rarely does. Asking it to list subscriptions, for example doesn’t work. Trying to get it to set up anything beyond a simple timer is a hit-and-miss affair.

The fact that they could be finally fixing this, and then are putting it behind a paywall is ironic, because if it finally works properly, people could actually start using it for buying stuff.

ern··on Microsoft points finger at the EU for not being able to lock down Windows
Would a bad driver update potentially have had similar consequences? (real question)

If so, this feels like a red herring.

ern··on Sparrows may be 'canary in the coal mine' for lead poisoning in children: study
As I understand it, much mining is done in Australia through FIFO (fly-in-fly-out) nowadays. It greatly reduces the need for infrastructure, boom-bust towns and issues like these.
ern··on My daughter (7 years old) used HTML to make a website
I decided to throw in the towel on frontend dev when I was forced to translate wireframes from a UX designer into pixel-perfect CSS (on a safety and time-critical project where the site was going to be used by back-office staff only, you've got to love how consultancies find ways to make $$$).

We had used Bootstrap and similar frameworks for years prior, but all the battling with different CSS layout techniques to render the UI on this project made me realize I was wasting my time, and the fact that the designer couldn't give developers working CSS made me wonder if the entire promise of separating design from functionality was a mirage.

ern··on AI's $600B Question
Corporate values. Drew the short straw, but had to present something.
