I have the highest regard for these terse, but information-dense displays that enable humans to quickly grasp all information they need to do their jobs, and nothing more. This is also something avionics provide - a modern cockpit displays are a work of art in layering needed information for what is happening at the time, both the dense PFD and the much specific that communicate aircraft status.

UI designers who were trained in the currently-popular paradigm would be at a complete loss to design such things. "Swipe left from the home screen, tap the nothingness on the screen to reveal the controls overlay, find the ••• in one corner of the screen, tap "More" in the 3-item menu, and then tap 'Bond Quote' in the modal dialog that takes over the entire screen." Keyboard shortcuts? "Hmm... interesting idea. Never thought of that. We might add those in a V2."

The corollary of which is that no function the driver might sensibly need while underway should be presented or accessed through a touch screen.
So physical levers and buttons. With some tactile feedback, such as raised lips or centre bumps or distinct shapes, so without looking the user knows which one their finger is on (third from left in the Aircon group). Displays can be present multiple items (don't need physical dials) but changing that display when driving comes back to buttons.

Strong disagree. I have been in UX reviews for products like Bloomberg terminals as the intended user. I specifically asked for information density and the designer looked at me like I was from the moon. Their counter offer was a permanent floating chatbot that covered the small amount of information still on the page. No joke. Information density is something those web designers genuinely could not comprehend.

This is the difference between accessible and efficient.
Bloomberg, and aircraft controls are expert interfaces, they have steep learning curves and in the latter require case extensive education to use (Bloomberg also does a ton of work on user training). Which is absolutely fine when efficiency trumps everything else and it's a system people use all day every day.
Most interfaces we use on a day to day basis are the opposite, they're designed to be accessible (in the sense that you can use it if you are unfamiliar, not disability) for someone unfamiliar, untrained, and uninterested in learning, which also aligns a lot of the time with sales growth. Nobody is willing to do a 6 week course to use the new HR UI really, really efficiently. The unfortunate thing is some of these are enterprise UIs some of us do have to use all day every day and that's where the impedance mismatch gets painful.

Accessibility peaked around Windows 95 and Windows 98 when buttons were clearly buttons, scrollbars were clearly scrollbars, and clickable text was in blue and underlined. We're now well past that, and without familiarity with disappearing scrollbars, three-dot menus and other obscure means of navigation, it's very unintuitive to get around. We don't even have manuals anymore if you do want to learn how things are supposed to be used.

What does the terminal really give you that you can't get from various other data sources scattered around the Internet, like your brokerage's own API, third-party data sources, various forums and subreddits, ...? Is it just the real-time firehose nature of the thing?
jll29 18 hours ago [-]
For instance, Bloomberg provide you with:
- real-time data on financial instrument prices;
- real-time news (own and syndicated);
- an email address (firstname.lastname@bloomberg.net) used to email and chat
with other professionals on the Bloomberg network. This is like LinkedIn and
WhatsApp combined for people in finance, and people can keep the address for
two years after e.g. losing a job, so they can use the network to find a new
role.
- analytical software: tools to calculate various KPIs to assess and analyze business opportunities.
- capability to transact: The BB terminal is not just an information system, it also permits you to buy and sell directly.

It's all that and much more. It has an enormous amount of data of all kinds that could be vaguely relevant in finance. BMAP can show you vessels (AIS data), location of LNG terminals, powerplants, bank branches, crop yield forecasts (just a few I picked off the list just now) and so much more on an interactive world map.
And every kind of price you can think of (almost). Crack spreads? River levels? Baseload power? Airline schedules? I am trying to think of more but it's truly VAST.
They have custom screens, configurable screens, custom settings (you want the generic futures contract to be rolled differently from the default? Sure...), option pricers and stuff I have never had to search for or look at.
They also have their own query language BQL for data queries and the BQNT platform is Python-based and optimized for use with the data.
If you just want the latest stock prices for your portfolio your online brokerage app probably does a better job.
The biggest miss right now is their ASKB AI chatbot, which is borderline moronic. It has to be some older model with low thinking/effort, because the first answer it gives is always broken in some way. Hallucinated functions or fields, outright wrong descriptions, etc. I don't even try to use the first answer anymore but ask it again to check its previous answer against verified and authoritative sources/documentation and will come up with many corrections.

That's called vertical integration, not an anti-trust violation.
It could be if they were the only one trying to offer this, but because it's so expensive, there are always multiple competitors trying to pick off their users. And when the next round of corporate cost cutting comes, they always come for the Bloomberg terminals, trying to push something cheaper.
But the cheaper alternatives are always inferior too (never mind the decades of muscle memory on Bloomberg).
Despite the price Bloomberg has maintained its number one position. I think in no small part that's also because their customer support is absolutely excellent. Press F1 twice and you're in a chat with the helpdesk; these days the initial query is triaged by AI of course, but for actual issues you're talking to a real human in less than a minute (sometimes just seconds), and these real actual humans typically have the expertise to help you. If not, the higher levels of support are good too. Don't underestimate this aspect!

Yeah, my reply’s a bit tongue-in-cheek. I don’t really oppose monopolies per se – it’s a free market, a better product could compete and win.
But one of the Bloomberg’s main selling points, at least from the last discussion I’ve read on HN (and some of the comments here too), is the chat, which means there’s network effects at play. So you can’t just build a better terminal, you also have to convince the majority to switch.
(Though apparently Bloomberg Chat also supports email? Maybe the competitor can use that to interface with it, so it’s only “green bubble” bad, not “all your colleagues are there and you’re not” bad.)

For many years ending around, a Bloomberg BusinessWeek paper magazine subscription was an incredible bargain. It was often possible (through tons of discount magazine sites) to get it for like $25 a year or less, and you could link that subscription online to get access to a lot of Bloomberg.com articles. Far from Terminal access of course, but I still really enjoyed the in-depth journalism and analysis. Around 2020 or so they pulled it off that type of distribution, now it's $100 a year and doesn't come with any online access other than the magazine articles themselves. And the full subscription to digital is $400 a year. It's priced just high enough to make it hard to justify for those who aren't real finance professionals. I really miss Bloomberg since the hard paywall went up.

Yeah, I think this is something a lot folks miss when doing UI/UX these days. There’s an immense focus on new users, not on folks who rely on it day in and day out for actual work. I’ve seen loads of old, incredibly “ugly” UIs that absolutely mog newer friendlier attempts at the same. They’re absolutely intimidating to new users, but once folks learn it they’re indispensable and obviously intentional.
I really wish there was a resurgence of information dense UIs and tools, optimizing for people who use them daily and not “use it once.” It really reminds me of the hate folks have for things like Eclipse or IntelliJ which are daunting at first but once you get over the shock and learn them really are amazing tools.
The difference is that Costco pays their employees well enough to keep them around (notice that Costco prints the start year on each employee badge- average retail length of service is 1 year, Costco keeps people around for decades) and so they can learn to use this older software and master it. Most retail operations optimize their inventory management for new people, because they don't expect someone to stick around long enough to master it.
My wife worked at a small regional chain of pharmacies that had an ancient MS-DOS based EHR system. And she mastered that system to the point where people would call her when she was home with me and ask her how to do something, and she would walk them through "okay, hit tab three times then shift-F12 then enter the frabble and then alt-F3 to go to the next screen and enter the drabble." It was difficult to learn it, but if you mastered it you could do everything you needed to do from just muscle memory while you were on the phone arguing with the doctor's office that their prescription was not correct and needed to be changed.
Then the small chain got bought by a national player and their brand new GUI system was brought in. It was a lot easier to learn- discoverability was a lot higher with menus and drop-downs and all of that. But if you stuck around to master it, you could never be as fast as you could with the older system. And that emphasis on quickly integrating new employees- but lower payoff for experience in employees- was clear in every choice that national chain made. They wanted their employees to be completely interchangeable, which meant that they didn't care if you had six months of experience or four years of experience or three decades of experience.
xp84 16 hours ago [-]
> Most retail operations optimize their inventory management for new people, because they don't expect someone to stick around long enough to master it.
Somehow I think I failed to think very deeply about this very important link! The twin happenings of the elimination of any retail career that pays a living wage, and the availability of GUIs and especially touch-screen GUIs happened simultaneously over a couple of decades, and the touch-screen dummy interface naturally won out. Not just because training that used to take two days for the 'green-screen' system I learned in 2001 now takes 15 minutes of instruction (and even that training is rather redundant for anyone over 95 IQ) -- also because the massive differential in productivity of an expert vs. new cashier/teller/pharmacy tech/etc. only even manifests if people are on the job long enough to become expert. And they're really not anymore.
Kinda why I prefer self-checkout. Even though the UI is firmly in "dummy" territory and I have to use a touch screen, I've used the current iteration of the self-checkout software more transactions than most cashiers I meet at Target, since they seem to have been there about 2 weeks on average.

Same story at my bank. Tellers used to speed run through a TUI, hitting tab and other key combos to accomplish things. Now it's a long wait with them mousing around.
xp84 16 hours ago [-]
The best thing about all character-based applications I've ever used is the keyboard buffer. Even if you're using a TUI on a system that has a slow backend, it almost always blocked the thread and didn't consume from the buffer during waits, so if you knew the sequence of keys was "Total, F1, 1, Enter, Enter, Tab, 2125551234, F10, 1, Enter" you could just enter all those keystrokes as fast as you could and the system would eventually catch up with you, meanwhile you were bagging a purchase or counting out the cash, whatever.
The GUI also has lag - especially in the era of web-technologies-bloat, more lag than ever - but whether touchscreen or mouse there can't be a buffer, so each lag requires you to stare waiting for the next UI to be drawn.

Unfortunately web-inspired TUI toolkits start to lose that property. Hit a key too fast, before the next screen runs code to attach its event listener? Sorry your key is lost.

This is a good point: you can build character-oriented interfaces "for dummies" — IBM i née OS/400 which Costco uses is actually good at this, with a standard interaction design centered around menus and form interfaces that map directly to CLI commands — and information-dense GUIs, but you can't very well build point-and-click interface with keyboard-style buffering.

I think that's the 'push/pull' problem though. Information dense UI that takes months or years to learn, or something that may be less information dense, but a monkey can learn it in minutes.
For me, it's typically a balance between speed and efficency of data to help you make decisions quickly, but should be able to be used by anyone with technical experience.

The modern Terminal is based on a private fork of Chromium to give it the look and feel of a VT100 terminal, and integrate their private networking and security technologies. The BBT predates HTTP, and backwards compatibility is hugely important to the company- they have a museum where a second-generation Terminal from ~1985 shows the current news, because they are so dedicated to backwards compatibility that they still can support the 1985 hardware.
apaprocki 21 hours ago [-]
This isn’t really true. The old terminal monitors are essentially dumb CRTs and the the museum pieces are just displaying the output from a regular PC running the modern app converted to an appropriate signal + BNC connectors so you see something and not just a black screen.
The old terminal hardware communicated over dedicated serial lines and worked in conjunction with many other “server-side” pieces of software that no longer exist, so it would be impossible to make one function as it did back in the day.

So much has changed since that time. There's a great recent talk by Jason Williams and Paul Williams that goes into a lot of detail [1]. Most things now use TypeScript developed natively in VS Code using extensions and a CLI for the additional proprietary bits. That all nicely integrates with agentic workflows, skills, etc. ComDb2 is very relational, very battle-as-in-jepsen-tested and has been open-source for a long time now [2]. C++ is still king, but there's plenty of Python, Go, Rust, Haskell, OCaml, etc. running around.
I would love to learn the specs of the original 1983 terminal. By the look of it, it's NTSC timings, so 200-ish lines, but it shows text and graphics, so it must have some bitmap capability. If I were to replicate the look, I'd use something that can display ReGIS or NAPLPS.

With the assortment of special-function keys that enabled the user to execute common tasks with only two or three keystrokes, I suspect that even actively-used Bloomberg terminals may see an order of magnitude less keystrokes.
(On the third hand... I seem to remember reading that the Bloomberg system included chatroom functionality, which may increase keystroke count)

At $32,000 a year per person the Bloomberg Terminal is a deeply unfair advantage for the rich to get richer.

youre assumming that the average person can use bloomberg profitably. thats absolutely not true. the average person gambles on crypto or polymarket

Yeah, but I think they just sell convenience and there are projects on GitHub like openbb that piece together something very similar for much less.

In finance, people who consider the cost of a Bloomberg terminal "expensive" are often considered "not serious" (small fish)... it has often been seen as a status symbol as well as a professional work tool.
jll29 18 hours ago [-]
Not really. If you ran a restaurant instead, you may also have to buy a few thousand dollars worth of ingredients and pay thousands of dollars in salaries per year and renting a venue to make the revenue that you are making. Even a pizza delivery service may need a few thousand dollars a year for a car and its driver plus petrol, taxes, insurance. Relevant is not the cost of doing business, but the annual revenue and margins.
E.g. $32k cost of business to make $2bn revenue statistically approximates zero.

I googled the ovens used by my local pizza joint and they were 25K each and there were two of them.

Not to sound like a YC fanboy here, but I love how pretty much every great business can be traced back to a start which somehow follows what YC talks about today.
I guess the first principles of what makes great Founders and great businesses from back in the gilded age to today have stayed the same.

I don't think the driver is supposed to use the touch screen while the vehicle is in motion
So physical levers and buttons. With some tactile feedback, such as raised lips or centre bumps or distinct shapes, so without looking the user knows which one their finger is on (third from left in the Aircon group). Displays can be present multiple items (don't need physical dials) but changing that display when driving comes back to buttons.

NB My car has loads of features that I would expect to use while driving that can only be accessed through the touch screen.
(increasingly everyone including the safety wonks are realizing why this is a bad idea)

Don’t get me wrong, I get the complaint. But it’s not like the designers are unaware of more information dense alternatives.
Strong disagree. I have been in UX reviews for products like Bloomberg terminals as the intended user. I specifically asked for information density and the designer looked at me like I was from the moon. Their counter offer was a permanent floating chatbot that covered the small amount of information still on the page. No joke. Information density is something those web designers genuinely could not comprehend.
Most interfaces we use on a day to day basis are the opposite, they're designed to be accessible (in the sense that you can use it if you are unfamiliar, not disability) for someone unfamiliar, untrained, and uninterested in learning, which also aligns a lot of the time with sales growth. Nobody is willing to do a 6 week course to use the new HR UI really, really efficiently. The unfortunate thing is some of these are enterprise UIs some of us do have to use all day every day and that's where the impedance mismatch gets painful.
I read this and then I think of glass doors with handles on both sides that I don't open till I read the instruction on the affixed plate: PUSH/PULL. The door forces this decision on every single conscientious user. These things are everywhere, including software interfaces.
It's so pure.
Of course. That's where all the hedge fund managers live.
There was one for visitor use at the Bank of America branch on Sand Hill Road in Silicon Valley at one time. But BofA closed that branch.
- real-time data on financial instrument prices;
- real-time news (own and syndicated);
- an email address (firstname.lastname@bloomberg.net) used to email and chat with other professionals on the Bloomberg network. This is like LinkedIn and WhatsApp combined for people in finance, and people can keep the address for two years after e.g. losing a job, so they can use the network to find a new role.
- analytical software: tools to calculate various KPIs to assess and analyze business opportunities.
- capability to transact: The BB terminal is not just an information system, it also permits you to buy and sell directly.
(My university has one BB terminal that MBA students can access and get training on.)
And every kind of price you can think of (almost). Crack spreads? River levels? Baseload power? Airline schedules? I am trying to think of more but it's truly VAST.
They have custom screens, configurable screens, custom settings (you want the generic futures contract to be rolled differently from the default? Sure...), option pricers and stuff I have never had to search for or look at.
They also have their own query language BQL for data queries and the BQNT platform is Python-based and optimized for use with the data.
If you just want the latest stock prices for your portfolio your online brokerage app probably does a better job.
The biggest miss right now is their ASKB AI chatbot, which is borderline moronic. It has to be some older model with low thinking/effort, because the first answer it gives is always broken in some way. Hallucinated functions or fields, outright wrong descriptions, etc. I don't even try to use the first answer anymore but ask it again to check its previous answer against verified and authoritative sources/documentation and will come up with many corrections. And then I do it again, and maybe a fourth time.
Maybe all they need to show massive improvement is a for loop of four iterations with the loop body being "are you sure, check the docs?" and return the result at the end.
Reducing the friction or feedback loop of information retrieval/analysis can change how people work just like repls and hotreloading did vs slow and long compiles
Oh, cool! An antitrust violation epitome!
It could be if they were the only one trying to offer this, but because it's so expensive, there are always multiple competitors trying to pick off their users. And when the next round of corporate cost cutting comes, they always come for the Bloomberg terminals, trying to push something cheaper.
But the cheaper alternatives are always inferior too (never mind the decades of muscle memory on Bloomberg).
Despite the price Bloomberg has maintained its number one position. I think in no small part that's also because their customer support is absolutely excellent. Press F1 twice and you're in a chat with the helpdesk; these days the initial query is triaged by AI of course, but for actual issues you're talking to a real human in less than a minute (sometimes just seconds), and these real actual humans typically have the expertise to help you. If not, the higher levels of support are good too. Don't underestimate this aspect!
But one of the Bloomberg’s main selling points, at least from the last discussion I’ve read on HN (and some of the comments here too), is the chat, which means there’s network effects at play. So you can’t just build a better terminal, you also have to convince the majority to switch.
(Though apparently Bloomberg Chat also supports email? Maybe the competitor can use that to interface with it, so it’s only “green bubble” bad, not “all your colleagues are there and you’re not” bad.)
The network effect is real and I don't think you can interface external email with it. You do get a Bloomberg email address as a user but I've never seen anyone in a chat with an external email only.
Next week it will be in Bloomberg Business Week, long after it had trading value. Bloomberg has its own news collection and analysis operation, bigger than almost all US newspapers.
Great value anyway. One of the only news sources focused on facts and meaningful stuff. Its been my go to news source for at least 15 years. I don't work in finance.
I really wish there was a resurgence of information dense UIs and tools, optimizing for people who use them daily and not “use it once.” It really reminds me of the hate folks have for things like Eclipse or IntelliJ which are daunting at first but once you get over the shock and learn them really are amazing tools.
The difference is that Costco pays their employees well enough to keep them around (notice that Costco prints the start year on each employee badge- average retail length of service is 1 year, Costco keeps people around for decades) and so they can learn to use this older software and master it. Most retail operations optimize their inventory management for new people, because they don't expect someone to stick around long enough to master it.
My wife worked at a small regional chain of pharmacies that had an ancient MS-DOS based EHR system. And she mastered that system to the point where people would call her when she was home with me and ask her how to do something, and she would walk them through "okay, hit tab three times then shift-F12 then enter the frabble and then alt-F3 to go to the next screen and enter the drabble." It was difficult to learn it, but if you mastered it you could do everything you needed to do from just muscle memory while you were on the phone arguing with the doctor's office that their prescription was not correct and needed to be changed.
Then the small chain got bought by a national player and their brand new GUI system was brought in. It was a lot easier to learn- discoverability was a lot higher with menus and drop-downs and all of that. But if you stuck around to master it, you could never be as fast as you could with the older system. And that emphasis on quickly integrating new employees- but lower payoff for experience in employees- was clear in every choice that national chain made. They wanted their employees to be completely interchangeable, which meant that they didn't care if you had six months of experience or four years of experience or three decades of experience.
Somehow I think I failed to think very deeply about this very important link! The twin happenings of the elimination of any retail career that pays a living wage, and the availability of GUIs and especially touch-screen GUIs happened simultaneously over a couple of decades, and the touch-screen dummy interface naturally won out. Not just because training that used to take two days for the 'green-screen' system I learned in 2001 now takes 15 minutes of instruction (and even that training is rather redundant for anyone over 95 IQ) -- also because the massive differential in productivity of an expert vs. new cashier/teller/pharmacy tech/etc. only even manifests if people are on the job long enough to become expert. And they're really not anymore.
Kinda why I prefer self-checkout. Even though the UI is firmly in "dummy" territory and I have to use a touch screen, I've used the current iteration of the self-checkout software more transactions than most cashiers I meet at Target, since they seem to have been there about 2 weeks on average.
The GUI also has lag - especially in the era of web-technologies-bloat, more lag than ever - but whether touchscreen or mouse there can't be a buffer, so each lag requires you to stare waiting for the next UI to be drawn.
In this video I made the mistake of using a debit card (still very slow to clear in 2005) which adds the delay https://youtu.be/pQCktMWR94Q?t=7
They replaced them with Windows-based touchscreen vending machines where each screen selection took as long as the whole former selection process took just to load.
For me, it's typically a balance between speed and efficency of data to help you make decisions quickly, but should be able to be used by anyone with technical experience.
So less of both. Less 'pretty UI' and less "omfg here is every piece of information shoved together and you need to be a wizard to understand it"
Nobody gets a promo from something that is working well for humans.
Most modern apps are very lazy on being actually useful for people that use it frequently
The old terminal hardware communicated over dedicated serial lines and worked in conjunction with many other “server-side” pieces of software that no longer exist, so it would be impossible to make one function as it did back in the day.

No, not really. Most likely something between a VT-220 and a VT-525.

The harder Bloomberg tries to control and restrict its users, the more users will just find alternatives or even build their own proprietary systems. It thinks it can be Apple in the financial data world, but I highly doubt it.
And has all the right buttons.

However, I suspect you're coming at this from the perspective of a coder or a gamer or some other category who types thousands of keystrokes per day (tens of thousands?). With the assortment of special-function keys that enabled the user to execute common tasks with only two or three keystrokes, I suspect that even actively-used Bloomberg terminals may see an order of magnitude less keystrokes.
(On the third hand... I seem to remember reading that the Bloomberg system included chatroom functionality, which may increase keystroke count)
Wow, what a great history artifact. It is hard to look at this and not wonder where did we go wrong. Everybody _should_ know better, and yet here we are. And now immortalized in the National Museum of American History for all posterity.
I'd love to know how they make frontends as responsive as possible. To the engineering blog!
