dfex··on Intel's Tofino P4 Software Is Now Open Source
Am I mistaken or has Intel pretty much shelved the Tofino switching hardware that supports P4 in the first place?

I seem to recall Oxide having to switch suppliers over this?

dfex··on Company of One: Why Staying Small Is the Next Big Thing for Business
Amen!

I've worked at multiple lean companies that were purchased by bigger public entities. Without fail, the "problem" the company existed for moves from delighting customers to financial engineering.

Since going it solo, it's been amazing how satisfying a job/business can be once you get a sense of what "enough" is each month. I find that going the extra mile for customers, even when you aren't getting directly paid for it is incredibly rewarding and knowing when I've made "enough" each month allows me the time to do this.

Don't get me wrong, I went hard in the first few years to build up some buffer, but it's amazing how powerful and enjoyable building goodwill is, and how it pays for itself down the line.

dfex··on Ask HN: How can I grow as an engineer without good seniors to learn from?
Came here to say this.

The Oil & Gas industry is not sexy and never will be, but it pays well above market and people with niche skills will do very well there (as you have no doubt now seen).

Technological progress in the space tends to move pretty slowly (especially on the Operational Technology side of the business) owing to many factors, but mainly risk avoidance. The flip-side of this is that once one company adopts a technology, the others tend to follow suite, so what you're doing may be very portable should the need arise.

Another benefit of O&G is that due the the specialised nature of a lot of the roles, you'll keep running into the same people at different organisations throughout your career, so keep your keep expanding your network along the way.

Don't let your perception of slow growth worry you too much - on the technology side, progression will come naturally as you take on new and more challenging projects. As a tech in a very different field, but a similarly isolated environment, I too have had these thoughts throughout my career, but remember there is a big wide world outside of silicon valley, and plenty of successful careers to be had.

It sounds like you have a boss you like who you could learn a lot from - this is huge. I'd focus on getting him to teach you to become a domain expert in the Oil & Gas space. This combined with your (relatively) niche technology skills will make you a unicorn in the future and combined with your network, pave the way should you want to become independent in years to come.

Good luck!

I've just arrived at the walk-off scene in Zoolander and have a still frame of Derek Zoolander's crotch to measure my life's progress.

Sounds about right.

dfex··on Have You Wanted to Quit Social Media?
For those struggling with the above, I'd add one more step that I learnt here on HN - go to assistive settings and set your phone's screen to Black & White. On the iPhone, triple clicking the lock button will do this for you.

You would be amazed how much taking colour out of the equation lowers the addictiveness of the content. I guess the people that make poker/slot machines knew about this decades ago, but I think this one step helped me more than anything else.

dfex··on Apple No Longer in Talks to Invest in ChatGPT Maker OpenAI
I was more referring to the statement:

> Also from my experience it's the counterparty that should feel honored to be working with Apple rather than the other way around

The Beats purchase was interesting in that I'm almost certain that Apple didn't need the technology for yet another set of headphones, but what they bought instead was the reputation/cultural allure of Beats, its founders and music catalogue.

I suspect Iovine and Dre are well beyond needing validation from or being "honored" to be working with Apple as both are such prolific creators in their own right(s).

dfex··on Ask HN: What's the "best" book you've ever read?
Interesting read - I thought that the reason the aliens sent the supercomputer probe things ahead of their invasion fleet was because they understood the humans capacity for advancement would far exceed their own capabilities if left unchecked for the duration of the invasion trip, indicating "pathetic" now, but capacity to be far superior.

Devoured all three books - really interesting hard sci-fi, although as noted by others, the first one took a bit of effort to work through.

dfex··on Ask HN: What's the "best" book you've ever read?
So much this. I too read the book when I was very young, and enjoyed it for its awesome mix sci-fi, absurdity, dry humour and absolute classic one-liners.

What I love about it now is how it presents a view of life in the universe as entirely random, but mostly harmless and fun, and that interplanetary exploration is something you would do as a hitchhiker on an adventure, rather than a conqueror chasing resources.

That vision really lifts me when contemplating the future and our place in it when we reach for the stars.

dfex··on AirPods Pro 2 adds 'clinical grade' hearing aid feature
No - I have only been trialling them for about 2 weeks after having substantial hearing loss on one side for 20+ years.

Thanks for your insight though - I was told "a couple of days" to get used to them would be enough.

dfex··on AirPods Pro 2 adds 'clinical grade' hearing aid feature
I sure hope so. Like I said, I'm only trialling them. Do you find they pretty much have no low-end/bass at all?
dfex··on AirPods Pro 2 adds 'clinical grade' hearing aid feature
I am currently trialling a pair of Phonak hearing aides (mid-range audio package, roughly AUD$5K) and I can assure you the sound quality is garbage even at this price point.

Yes, they pick up sounds I don't normally hear, but I would compare the experience to listening to world through a cheap high-school PA system.

Genius! Though for that price and the "license fee", the council should be providing you with a free pensioner and/or lawn chair.

> Residents will need to pay an application fee of £108 and if their application is successful, they will pay a further £1,251 for construction costs and a licence for the first year.

...and after handing all that money over, will be thwarted from charging their vehicles when someone else parks outside their house in that spot.

dfex··on Kien, the most-delayed video game in history, released after 22 years
I think you'll find the market for GBA cartridges is alive and well - those handhelds are indestructible, and small release games like this will sell out and be traded by collectors.

And for those who aren't sure about buying a 2nd-hand gaming device from checks notes 23 years ago, you can get yourself something more modern to play it on: https://www.analogue.co/pocket

dfex··on Electricity prices in France turn negative as renewable energy floods the grid
> But its not like grid operators back in the control rooms are disconnecting solar farms because the grid is oversaturated.

In Australia, this has been happening for some time - plants are literally having their output dialled back (or even being disconnected entirely) during peak times by the market operator.

dfex··on New material looks like frosted glass but lets in more light than a window
Thank you for this - the article had me wondering: if they are putting the PMMM film over glass, what's the point? - any extra transparency from the film will just be negated by the glass, but in the paper it appears they have developed a PMMM panel that they used in testing.
dfex··on Eight years of organizing tech meetups (2023)
Thanks for this timely post!

I have been kicking around the idea of starting a meetup in my city to meet interesting people in my field.

Being a freelancer on large projects in my day job, it sometimes feels like I'm out of the loop for long periods of time.

dfex··on Ask HN: What nonfiction books do you keep rereading?
You're mostly there - your hub definition is spot on - it's basically an electrical repeater and doesn't inspect the packet in any way* and operates at half-duplex.

Switches (specifically Layer 2 switches) will send broadcast frames to all ports*, but traffic that is unicast to a specific MAC address will only be sent to the port where that MAC address was learnt. To keep track of the MAC address to port mappings, a switch will have one or more "forwarding" or "MAC-address" tables.

Routers (and Layer 3 switches) are not necessarily Internet connected, but will mostly be seen in larger networks. Being mostly Ethernet-based these days, they maintain two tables - an ARP table (mapping IP Addresses to MAC Addresses) and a routing table (mapping IP prefixes/routes to destination IP addresses). When an IP packet comes into a port, the router will consult it's routing table and find the most specific route that matches the destination of the packet. From the destination IP of the route, it will then determine the egress interface that it should send the packet towards, then use the ARP table to work out the destination Ethernet MAC address for the Ethernet frame it will construct to transport the IP packet in on it's way to the next-hop router.

* During the early 00s there were "Dual-Speed Hubs", which were basically two hubs (one 10Mbps, one 100Mbps) joined together internally via a two-port Ethernet switch. Fortunately the price of 100Mbps Ethernet switches kept falling and they weren't around too long.

* Provided those ports are all members of the same broadcast domain/VLAN

dfex··on Figma OSS Alternative
Another vote for Inkscape here - amazing tool. I probably use less than 1% of it's functionality, but it is far and away the best PDF editor I've come across (I work with a lot of design drawings that started life as DWG/CAD files, are exported to PDF and sent around for proofing/review and need to have changes marked up on them).
dfex··on Visualizing malicious IP addresses
> Upon closer inspection of Asia, we can notice a significant number of addresses located in South Kora, (and possibly North Korea?), as well as in Taiwan.

> I was surpised to see that the distribution of attacks is extremely uneven with most of it concentrated in parts of Asia, Europe, and the US, and (almost) none from South America, Middle East, and Russia.

Aside from the casual stereotyping of bad actors here, the article completely neglects the fact that just because the attack is sourced from a certain IP/geolocation doesn't mean that the attacker resides in that location.

What you most likely have is a listed of pwned PCs with fast internet connections being used in botnets.

dfex··on Meta Horizon OS
> I've been dwelling in some nostalgia recently and miss some of the earlier days when everything wasn't so homogenous.

You are not alone in this. I see announcements like this one from Meta and others like Oxide - companies out there having a swing in a different direction and it makes me glad that there are people out there thinking outside the monoculture that computing feels like it's become sometimes.

Sure, standardisation has been good in some respects, but I feel like the incentive to really innovate (as opposed to incrementally improve) in the operating system and compute space has really dried up.

Not so much Monument Valley-like, but I also found The Room tetralogy (quadrilogy?) very enjoyable. Certainly a very different aesthetic from Monument Valley's whimsical colour-palette and story line, but excellent puzzles nevertheless.
dfex··on Intel Gaudi 3 AI Accelerator
The ABit BP6 bought me so much "cred" at LAN Parties back in the day - the only dual socket motherboard in the building, and paired with two Creative Voodoo 2 GPUs in SLI mode, that thing was a beast (for the late nineties).

I seem to recall that only Quake 2 or 3 was capable of actually using that second processor during a game, but that wasn't the point ;)
