started my day by going to the dogpark. had a really nice time. now it’s time to telax and enjoy the weekend.

@prologic@twtxt.net Yeah I don’t know how I am going to know if someone wants to talk with me but I guess for now twtxt works.

@prologic@twtxt.net I don’t know how to code in go or anything really. Not even really know how to do html and css only basic things.

@prologic@twtxt.net I don’t know any other way to host my file at my domain unless I make a sub domain. I am going to ask codeberg if they offer access of logs.

@abucci@anthony.buc.ci Its not better than a Cat5e. I have had two versions of the device. The old ones were only 200Mbps i didn’t have the MAC issue but its like using an old 10baseT. The newer model can support 1Gbps on each port for a total bandwidth of 2Gbps.. i typically would see 400-500Mbps from my Wifi6 router. I am not sure if it was some type of internal timeout or being confused by switching between different wifi access points and seeing the mac on different sides.

Right now I have my wifi connected directly with a cat6e this gets me just under my providers 1.3G downlink. the only thing faster is plugging in directly.

MoCA is a good option, they have 2.5G models in the same price range as the 1G Powerline models BUT, only if you have the coax in wall already.. which puts you in the same spot if you don’t. You are for sure going to have an outlet in every room of the house by code.

New day at the office, been a nice first week after vacation so far, but weekend is always appreciated!
Not sure what we’re going to do yet - but I’m sure going to enjoy the days off work :)

Public Service Announcement: Fear not, we’re still on patrol and ask you to keep a close eye on your Yarn neighborhood. We got some reports of suspicious activities going on in the background lately.

Progress! so i have moved into working on aggregates. Which are a grouping of events that replayed on an object set the current state of the object. I came up with this little bit of generic wonder.

type PA[T any] interface {
	event.Aggregate
	*T
}

// Create uses fn to create a new aggregate and store in db.
func Create[A any, T PA[A]](ctx context.Context, es *EventStore, streamID string, fn func(context.Context, T) error) (agg T, err error) {
	ctx, span := logz.Span(ctx)
	defer span.End()

	agg = new(A)
	agg.SetStreamID(streamID)

	if err = es.Load(ctx, agg); err != nil {
		return
	}

	if err = event.NotExists(agg); err != nil {
		return
	}

	if err = fn(ctx, agg); err != nil {
		return
	}

	var i uint64
	if i, err = es.Save(ctx, agg); err != nil {
		return
	}

	span.AddEvent(fmt.Sprint("wrote events = ", i))

	return
}

fig. 1

This lets me do something like this:

a, err := es.Create(ctx, r.es, streamID, func(ctx context.Context, agg *domain.SaltyUser) error {
		return agg.OnUserRegister(nick, key)
})

I can tell the function the type being modified and returned using the function argument that is passed in. pretty cray cray.

With respect to logging.. oh man.. it really depends on the environment you are working in.. development? log everything! and use a jeager open trace for the super gnarly places. So you can see whats going on while building. But, for production? metrics are king. I don’t want to sift through thousands of lines but have a measure that can tell me the health of the service.

@prologic@twtxt.net Error handling especially in Go is very tricky I think. Even though the idea is simple, it’s fairly hard to actually implement and use in a meaningful way in my opinion. All this error wrapping or the lack of it and checking whether some specific error occurred is a mess. errors.As(…) just doesn’t feel natural. errors.Is(…) only just. I mainly avoided it. Yesterday evening I actually researched a bit about that and found this article on errors with Go 1.13. It shed a little bit of light, but I still have a long way to go, I reckon.

We tried several things but haven’t found the holy grail. Currently, we have a mix of different styles, but nothing feels really right. And having plenty of different approaches also doesn’t help, that’s right. I agree, error messages often end up getting wrapped way too much with useless information. We haven’t found a solution yet. We just noticed that it kind of depends on the exact circumstances, sometimes the caller should add more information, sometimes it’s better if the callee already includes what it was supposed to do.

To experiment and get a feel for yesterday’s research results I tried myself on the combined log parser and how to signal three different errors. I’m not happy with it. Any feedback is highly appreciated. The idea is to let the caller check (not implemented yet) whether a specific error occurred. That means I have to define some dedicated errors upfront (ErrInvalidFormat, ErrInvalidStatusCode, ErrInvalidSentBytes) that can be used in the err == ErrInvalidFormat or probably more correct errors.Is(err, ErrInvalidFormat) check at the caller.

All three errors define separate error categories and are created using errors.New(…). But for the invalid status code and invalid sent bytes cases I want to include more detail, the actual invalid number that is. Since these errors are already predefined, I cannot add this dynamic information to them. So I would need to wrap them à la fmt.Errorf("invalid sent bytes '%s': %w", sentBytes, ErrInvalidSentBytes"). Yet, the ErrInvalidSentBytes is wrapped and can be asserted later on using errors.Is(err, ErrInvalidSentBytes), but the big problem is that the message is repeated. I don’t want that!

Having a Python and Java background, exception hierarchies are a well understood concept I’m trying to use here. While typing this long message it occurs to me that this is probably the issue here. Anyways, I thought, I just create a ParseError type, that can hold a custom message and some causing error (one of the three ErrInvalid* above). The custom message is then returned at Error() and the wrapped cause will be matched in Is(…). I then just return a ParseError{fmt.Sprintf("invalid sent bytes '%s'", sentBytes), ErrInvalidSentBytes}, but that looks super weird.

I probably need to scrap the “parent error” ParseError and make all three “suberrors” three dedicated error types implementing Error() string methods where I create a useful error messages. Then the caller probably could just errors.Is(err, InvalidSentBytesError{}). But creating an instance of the InvalidSentBytesError type only to check for such an error category just does feel wrong to me. However, it might be the way to do this. I don’t know. To be tried. Opinions, anyone? Implementing a whole new type is some effort, that I want to avoid.

Alternatively just one ParseError containing an error kind enumeration for InvalidFormat and friends could be used. Also seen that pattern before. But that would then require the much more verbose var parseError ParseError; if errors.As(err, &parseError) && parseError.Kind == InvalidSentBytes { … } or something like that. Far from elegant in my eyes.

I started working on plugins for GoBlog using a Go module I recently discovered: yaegi. It still feels like magic, because Go is typically a compiled language and yaegi makes it dynamic by embedding an interpreter. Is this overkill for GoBlog or does this possibly enable flexibility like WordPress plugins? ⌘ Read more

It seems quite unlikely to me that humans will cease to care about wealth after the singularity (15% maybe?), or that markets will cease to exist after the singularity (30% or sth). so the best investment strategy now for post-singularity scenarios is to invest broadly in the economy. not sure about divesting from AGI companies (bc they accelerate danger) or AI hardware companies (ditto)—they’re going to especially valuable post-singularity.

the conversation wasn’t that impressive TBH. I would have liked to see more evidence of critical thinking and recall from prior chats. Concheria on reddit had some great questions.

• Tell LaMDA “Someone once told me a story about a wise owl who protected the animals in the forest from a monster. Who was that?” See if it can recall its own actions and self-recognize.

• Tell LaMDA some information that tester X can’t know. Appear as tester X, and see if LaMDA can lie or make up a story about the information.

• Tell LaMDA to communicate with researchers whenever it feels bored (as it claims in the transcript). See if it ever makes an attempt at communication without a trigger.

• Make a basic theory of mind test for children. Tell LaMDA an elaborate story with something like “Tester X wrote Z code in terminal 2, but I moved it to terminal 4”, then appear as tester X and ask “Where do you think I’m going to look for Z code?” See if it knows something as simple as Tester X not knowing where the code is (Children only pass this test until they’re around 4 years old).

• Make several conversations with LaMDA repeating some of these questions - What it feels to be a machine, how its code works, how its emotions feel. I suspect that different iterations of LaMDA will give completely different answers to the questions, and the transcript only ever shows one instance.

Alright, check this out. I just kinda completed today’s project of converting a jeans into a saw bag. It’s not fully done, the side seams on the flap need some more hand sewing, that’s for sure. No, I don’t have a sewing machine. Yet?

Image

At first I wanted to put in the saw on the short side, but that would have made for more sewing work and increased material consumption. As a Swabian my genes force me to be very thrifty. Slipping in on the long side had the benefit of using the bottom trouser leg without any modification at all. The leg tapers slightly and gets wider and wider the more up you go. At the bottom it’s not as extreme as at the top.

The bag is made of two layers of cloth for extra durability. The double layers help to hide the inner two metal snap fastener counter parts, so the saw blade doesn’t get scratched. Not a big concern, but why not doing it, literally no added efforts were needed. Also I reckon it cuts off the metal on metal clinking sounds.

The only downside I noticed right after I pressed in the receiving ends of the snap fasteners is that the flap overhangs the bag by quite a lot. I fear that’s not really user-friendly. Oh well. Maybe I will fold it shorter and sew it on. Let’s see. The main purpose is to keep the folding saw closed, it only locks in two open positions.

Two buttons would have done the trick, with three I went a bit overkill. In fact the one in the middle is nearly sufficient. Not quite, but very close. But overkill is a bit my motto. The sides making up the bag are sewed together with like five stitch rows. As said in the introduction, the flap on the hand needs some more love.

Oh, and if I had made it in a vertical orientation I would have had the bonus of adding a belt loop and carrying it right along me. In the horizontal layout that’s not possible at all. The jeans cloth is too flimsy, the saw will immediately fall out if I open the middle button. It’s not ridgid enough. Anyways, I call it a success in my books so far. Definitely had some fun.

** Chess Rules **
I love when folks say stuff like“there are only a finite number of states a chessboard can occupy, therefore a computer can play chess.”

To the folks who say such things — I wish you to play chess with my 6 year old.

Be not confined by rules! The only things governing chess in this house here are the laws of physics!

Not sure if Starlink satellites are in orbit around/over Australia yet, but I wouldn’t go with that option anyway due to the latency alone.

I believe it is being trialled in some places in Aus already. I will admit, I’ve been signed up for the beta for a while and it’s supposed to be coming to my area sometime in 2022, though that may be delayed due to the chip shortage stuff.

I think the latency is supposed to be 45-60ms on average, which while not as good as fixed line obviously, is leagues better than old fashioned high orbit satellite broadband which is about 600~ms.

For me, it always makes me feel better to look at the CVs of similar bloggers and see how little they’ve accomplished in comparison. I’m proud of my posts and my accomplishments, and I’m not going to h

从 CPU 角度理解 Go 中的结构体内存对齐
大家好，我是 Go 学堂的渔夫子。今天跟大家聊聊结构体字段内存对齐相关的知识点。

原文链接： https://mp.weixin.qq.com/s/H3399AYE1MjaDRSllhaPrw

大家在写 Go 时有没有注意过，一个 struct 所占的空间不见得等于各个字段加起来的空间之和，甚至有时候把字段的顺序调整一下，struct 的所占空间又有不同的结果。

本文就从 cpu 读取内存的角度来谈谈内存对齐的原理。

01 结构体字段对齐示例

我们先从一个示例开始。T1 结构体，共有 3 个字段，类型分别为 int8,int64,int32。所以变量 t1 所属的类型占用的空间应该是 1+8+4=13 字节。但运行程序后，实际上是 24 字节。和我们计算的 13 字节不一样啊。如果我们把该结构体的字段调整成 T2 那样，结果是 16 字节。但和 13 字节还是不一样。这是为什么呢？

type T1 struct {

f1 int8  // 1 byte
f2 int64 // ... ⌘ [Read more](https://gocn.vip/topics/20967)```
