The behaviour is a bit weird - I just opened mine and in Chrome task manager it showed the ram use climbing to 2.8GB, but in the network console it only shows a few 10s of mb download. I wonder what the discrepancy is? The site seemed to notice the console was open and behaved differently also.

I think that’s normal, I would expect RAM use to dwarf network transfer on most modern JS-heavy sites. If a page downloads 1MB JSON, that could easily take 10MB (maybe much more?) RAM when parsed into an object. And JS code itself probably has a similar increase in size just by getting parsed into an AST. And all that is before really executing anything - once the dozens of shitty third party scripts start whirring,…

It's quite impressive though. I'd estimate the content on my screen is about 1MB if you'd just sent it as images and html so that's quite a junk to content ratio.

The juxtaposition between this and "Voyager 1 runs on 69 KB of memory and an 8-track tape recorder" is probably the best one I've seen in a long time

That was probably an incredible amount of memory back then. And it probably cost $1,000 USD for 1KB. Who knows how much radiation-hardened space memory was. 10 times that?

In consumer space, 69 KB of RAM (138 x 4 kbit chips) would cost around $1700 70s dollars for the entire package, ~$10k in modern dollars.

Radioationed hardened for space though — $50k-$100k in 70s dollars, roughly the price of a Silicon Valley house back then - $300k-$600k in today's money.

>How do we get to gigs? Microsoft, who has owned LinkedIn since 2016, has recently been making headlines because recently they fired a lot of their engineers and QA staff and are now essentially vibecoding huge chunks of their enterprise. What's more, Microsoft never paid the really big bucks like the FAANG companies, and so it's more or less an open secret that at the height of the tech hiring frenzy Microsoft had t…

"What's more, Microsoft never paid the really big bucks like the FAANG companies" I never knew this open secret. In my day msft was very glamorous and I guess something like oracle played the role you're ascribing to msft now. I wonder what their strategy was? (I tend to doubt this was a careless/unexamined decision.) Maybe they figured that paying extra for individuals doesn't get you much if you have enough structu…

Good question. For a long time I think the justification was location: Microsoft is in Seattle, and it’s only the Bay Area that is getting inflated salaries.

Voyager 1 is several orders of magnitude simpler as a product so it makes sense that it uses several orders of magnitude less memory.

I think Google closed Google+ because it worked as social media and they couldn't find better ways to exploit users.

Oh they tried to - in a simple "please fill out the form" way. I'll link to my prev comment: https://news.ycombinator.com/item?id=46425198#46429370 IIRC they tried at some point incorporating G+ on youtube but that didn't work either

That's true. I was much younger back then to notice about privacy.

Yeah, it was pretty bad incorporating G+ account to everything. The way the G+ worked (at least in my friend circle), normal people had less business there. It was very hobby focused.

Very few people with LinkedIn profiles read the social feed. Even fewer post things to it. The majority use LinkedIn only for job searching and keeping contacts. I do some times wonder if any hiring managers see a lot of LinkedIn social post activity as a positive thing. The few times we’ve interviewed candidates who had a lot of LinkedIn posting activity it was considered a risk: We could go through their LinkedIn a…

Anecdotally, I've noticed a correlation between spikes in LinkedIn social activity and subsequent job changes, after which the activity (typically) subsides again. The activity doesn't even have to be actively posting, just reacting to posts on their feed. I think the dynamic you're observing is partly people just reacting to stuff (or if posting actively, fluffing up their "professional presence") as they do a job h…

Yeah and updating profile image, profile description and description for work history. Almost no one that isn't looking around for a job does this.

Web developers of HN: how is this possible? What can use 1.2GB RAM for a website? Preloaded all videos?

Keep in mind this is memory used by a browser tab, not "how bug the website is". Probably a memory leak as the feed is scrolled or something, but it is a massive download when you first load the page. I'm seeing 72MB in the network tab (7MB transferred--that's due to compression). An incredible 10MB is HTML (800K transferred), a more incredible 11MB of CSS (500K transferred), 25MB of JS (3MB transferred), 16MB XHR (1…

You got me curious so I checked latest release Brave: new "blank" tab. 47.8MB

Let's be real, LinkedIn is full of LinkedIn Lunatics but pretty much all mainstream social media is pretty shit. They're just different flavors of shit. LinkedIn: bad. Facebook: bad. Twitter: I literally think it contributed to the collapse of discourse and rise of shallow thought / rejection of expertise. I'm not going to list more because the theme is, you guessed it, they're bad. Google+ had promise in that the ma…

> Google+ had promise

No ads was a huge plus. Take away the financial incentive and you get rid of most of the worst behavior.
