Its hard to make a commercial decision for something that’s coming someday. But I hope it does arrive - I like Swift as a language (OMG - it was such a pleasure after the ugliness that is Objective C).

ROFL.

True on desktop OSs. I did quite a bit of commercial dev on GTK many years ago, but I always found the look and feel on Mac (esp) and windows quite klunky. I hear that quite a bit of work has been done on native theming, so perhaps my impressions are out of date. Having said that - GTK wasn’t bad to work with. I also did a project in WxWidgets, but again desktop only. It was not too bad for simple apps.

For the current app - first release target was iOS, then Mac, Android, Windows then Linux. So GTK was out since its not mobile friendly (I have heard you can do something on Android, but iOS is out).

Well… this is pretty crappy.

I built a Xamarin app (mac/iOS) because I wanted portability to windows. Then I was forced to upgrade to .net 6/7 because of a library I needed, and that meant upgrading to .Net for Mac/.Net for iOS (which is part of MAUI, but not using MAUI UI controls). MAUI is definitely undercooked at the moment.

What an awful and painful process, but I’m finally there… and they drop the main IDE for development. Damn.

VSCode doesn’t have a visual UI designer (well… neither does VSMac, but it does prepare a copy of your project and opens XCode for editing the storyboard/images, and copies changes back). So does this mean they will add that to VSCode? Or will we all have to switch to raw edits of XML to create UIs like you have to do with MAUI? Ick.

Developing GUIs for windows using MS tools is a lesson in frustration, especially when you want to have cross platform capabilities… WPF -> WinForms -> Xamarin -> Xamarin.Forms -> MAUI/.Net for {Mac,iOS}… Not to mention UWP… Each transition is a rewrite. Damn.

Be wary of RAID 5 or 6.

They both have a « write hole » problem (or though much less so in RAID 6). Any power failure which causes an incomplete write can cause a complete RAID corruption - meaning all data is lost. Hardware RAID controllers usually have an onboard backup battery so they can store some information to complete operations should there be a sudden power failure. Software RAID does not have this, and you need to provide a UPS with automatic clean shutdown as the battery runs low using nut or some equivalent.

Some people go as far as to say that RAID 5 should never be used.

You also have very long recovery times when you replace a failed drive (days). Any other failure during this time means total data loss (of course RAID 6 gives you a second redundancy). Weekly Resyncs are very slow too (hours to days), and (unless you constrain your max throughput) will bring your system to its knees.

zfs does not suffer from these problems, BTW.

I run software RAID 5 via mdadm and have a UPS. I’ve replaced drives twice with no issues other than a slightly nervous long wait during recovery. I’m too cheap to buy the extra HDD for RAID 6, and may end up regretting it one day.

My $0.02c worth - I have run all sorts of servers at home over the years, and one of the main challenges around the hardware is managing heat.

I’ve used mini-ITX mobos and tiny cases for builds. They look gorgeous, but at some point, when you stick enough drives in there (assuming you can) or make the CPU/GPU busy, you are going to have a heat problem, or a noise problem, or both.

On my mythtv build I used M-itx and a gorgeous Lian Li small case. It was a beautiful add to my home theatre stack, but in the end I drilled a ton of small holes in the top and added a slow 140mm fan to control the heat without noise.

The same goes for my file server - it was a slightly larger case with no GPU, but once I added my 6th HDD and had a ton of services running, heat became an issue and I was having to add extra fans, which could only be 80mm so they ran fast and noisy.

My new build I’m going to go all the way with a Phanteks Enthoo Full Tower and a few 120mm fans. I’ve decided that looks don’t matter

The other problem for me with these tiny builds is cable management. I’m complete shit at it, and small builds requires some skills. A big case gives you space to spread those cables out.

Lastly, you can get ATX or EATX mobos with 6, 8 or more SATA connectors - room for growth! And there are very low power options available.

I’ll soon have the appleTV + TV upstairs, laptop in the office, and the monster server downstairs with cat-6 + Gb fibre throughout.

That caps lock light is so cool, but I guess it makes sense since keyboard drivers need to change it.

A great form factor with a superior OS (IMHO).

It could well be survivorship bias, but I did represent the examples as personal. Having said that - I did a quick google for « laptops with longest lifespan » and most of the reviews had apple at #1 or 2.

In common with you, most of my previous laptops (5 or 6) were thinkpads like yours, usually the tablet style for OneNote (which is awesome BTW). They never survived the rigours of the road. Perhaps that’s why I had a different result to yours - I used to travel 3-6 months a year.

They sure do, and its a complete bastard. Soldered ram and disk.

My latest laptop has 96GB RAM (I run a lot of VMs) and 4TB SSD. I think I should get the full 5 years out of it.

That was an awesome laptop with upgradable components. Nice!

IIRC weren’t some of the peripheral drivers a bit dodgy.

Sad, but true. If a CEO is not maximising profit, then the shareholders can sue, and the board (who represent the shareholders) can replace the CEO.

I wish this structure had a longer term view so that a CEO can also do what’s right - such as make decisions that might lose money now, but have a greater long term value (where value is not only defined by share price, but also things like goodwill, reputation etc).

Repairability has just never been a high priority for them (which is bad). But it is becoming so, thanks to various governments forcing the issue.

I’m an old Linux-head (actually started out developing tools for 10’s of variants of unix - compilation flags providing custom versions). I would love to have my mac mini running linux though, that would be awesome. I don’t think you can yet.

I think their engineering is pretty good, personally. I travelled a lot with a laptop from 2000 to about 2020, and my windows laptops would always die after 2 years - hinges, cracks in the body, screen cracks and so on. Moving to apple’s laptops in about 2011 meant I got 5 years out of each (air then a pro). I’m now on a second pro, but the old pro is still trucking along.

I’m not going to defend all their decisions, there’s a lot of questionable stuff in there (keyboards, sticking to lightening, mice…). But their hardware, both laptop, mini and pro) has been solid.

You are right about repairability. I think that has never been a key feature for them hence the glue, security screws and other crap. Fortunately there are governments around the world that are pushing for repairability, consistency with usb-c, replaceable batteries and more. So I think all manufacturers will be upping their game now, which is awesome.

All manufacturers reduce cost - supply chain management and manufacturability are the processes to drive that. Apple are really good at the supply chain side, that was Tim Cook’s focus as COO. What I don’t like is that they are able to keep their incredibly high margins (far higher than any other manufacturer) thanks to their software, interoperability and walled garden.

I have a lot of apple kit - I appreciate their over-engineered approach to a lot of hardware, and I like their approach to privacy.

But they do make mistakes in design - the puck, the aerials, butterfly keyboards, unrepairability of design…

And one thing I really hate is their response to those errors. Its almost always to blame the user. I just wish they would be honest.

My 5 year old brother color laser is awesome. Cheap to run and toner doesn’t dry out, and it doesn’t wake up in the middle of the night and clean (i.e. use up) the ink.

However having seem comments like this, I think I will hold off on any firmware updates.

While technically that is true, if you have any other users they will be annoyed. And anyone running iOS will almost immediately get regular popups about the mail server being down (because iOS checks for new mail frequently - and yes I know this can be adjusted) and so they will be telling you straight away.

Also - I’m not convinced that all email servers obey the SMTP standard.

I forgot to mention - spam isn’t too bad with a well trained SpamAssassin.

Plus you will need to learn your virtualisation tool really well because of all the networking routes required and operating it on the command line. VBoxManage is your friend, but its just not friendly.

From a security perspective - I did everything in Linux, and only opened the required ports (plus ssh, which I moved to a random high port number). I have auto-update on for security patches, but NOT for regular patches (because Zimbra tends break things, so you need to snapshot first).

I’ve been running my own mail server for about 15 years now… Let me offer some insights.

• Its used by me and the family, so I do have other users who expect things to work.
• I used commodity hardware, with a Linux host (and guest).
• the mail server runs in a VM, so it is trivial to: stop, copying the VM to USB, restart.
• Maintaining uptime isn’t too bad, but when the mail server goes down, you need to get onto it quickly. I’ve had power supplies fail, HDD’s fail, memory fail.
• If you should happen to be out of town when a failure occurs (I’ve had this twice), then the server stays dead until you are back. That does not make your users happy. If its more than 4 days, then the SMTP standard says email is lost.
• There have also been a few software issues with Zimbra (my current tool) - the stats daemon filled the disk, the upgrader broke permissions all over the place multiple times. Each of these requires time to investigate, research online etc. Snapshotting is awesome! Right now I have a problem where the VM disk file is growing, but the space used inside the VM is not. I have zero’d out free space and compacted the VM but don’t know why it is happening yet. More research needed.
• You will learn to hate blocklists. There are many, and there are meta blocklists. You have to watch them because at any time, you will be added and your email will silently get dropped. Sometimes the blocklist trashes whole subnets because of a single actor, sometimes even more, and so you will get included due to other bad actors. Getting off a blocklist is hard… you send emails, you fill in web forms, you look for a contact details, you wait… Then some number of days/weeks later, you are off again.
• You have to learn DKIM, SPF, DMARK, managing DNS etc.
• I used to use self-signed certs and live with the warnings. Now I used Lets Encrypt, which is awesome!.
• You can try to get reverse DNS working, but that’s up to your ISP (who usually don’t care, so good luck). No rDNS can be viewed as bad by email recipients so your spam score starts at >0.
• If you run it at home, you will be part of a block of IPs that are known to be home users, so your spam score starts at >0.
• I’m lucky in that I run it on a spare public IP address on my server housed at work. But that will need to change soon.

I started using native Linux mailboxes, later added roundcube (web UI), investigated Mailinabox, but now use zimbra. That gives me calendar/contact sharing, email/calendar/contacts to iOS devices (which is the main way my family get email), and lots more. Moving data from one to the other took a couple of days of effort. (Yeah… I know its supposed to be trivial, but its not when you include tool research, testing, execution one at a time etc).

Bottom line - you will learn lots, you will lose many weekends and sometimes a weekday here or there as you try to handle emergencies, it will never be set-and-forget.

My original rational was learning, privacy and my own domain and nicer looking email addresses than john1234@gmail.com. I’m looking for an online alternative as its time to lighten the load, but I have a lot of services that we use in Zimbra.

Good luck with it!

The thing to remember with these examples is that those companies would have royally fucked up their purchases. Big companies always impose a culture and a mindset.

AT&T would definately have crushed the internet with a monopoly - we would have had to use AT&T approved internet devices, and they would have brought long distance type charges to it. Oh so your email is going overseas? That’s an extra 10c.

Same with Google and Netflix. They were all able to continue with the founders vision and create something special.

I gotta take my hat off to the GOP here. While both parties have gerrymandered, the GOP have taken it to the extreme. They will lock in their ruling majority (despite losing at the polls) in every state where they control the Supreme Court and legislature. They will become unassailable in those states.

They know they have to do this - they are (or will be) in the minority.

The Supreme Court did the USA a disservice because they could have tempered the worst excesses of the various states. But they have declared themselves hands off - let the states decide.

Sigh.
