I always hear the "your LTV To CAC" ratio must be > 3.

Why? Is the assumption that the LTV is spread out over a period of time that such a low ratio would cause a low CAGR?

I'd assume if one's payback period were let's say 2 hours instead of 18 months, one'd be fine with with a LTV/CAC of let's say 1.1. Is my logic correct?

When you say "I would recommend learning more code instead" it's aggressive since there are different areas of expertise that contribute to a product. But in general, anything that is not "code" is underrated by software engineers. I would recommend learning more product design instead :o)

I can comment on this from my experience. I studied Computer Science, and my passion for UI development led me to switch to product design after being coding for more than 10 years. I design with code too, and I did many prototypes using different UI frameworks.

But, there are different design activities, and sadly not a single tool is adequate for all.

If you are making decisions about UI layout, visuals, or UI motion working with code may slow you down. Even if you use CSS grids and flex, there is a penalty caused by the lack of direct manipulation and the freedom to try multiple ideas quickly.

To me, the author just wants better refactoring and maintenance tools over the existing visual design tools. It's a little bit disappointing that design tools evolved in many areas, but did a regression in others. For example, more or less in 2008, Microsoft did a tool called Expression Blend. The tool, based on ideas from Bill Buxton, had the goal to maintain a continuity between mocks and the final implementation. You were able to import PSD layers and later convert them to components, or to sketch the UI flow in the tool. I never used it for anything more than simple experiments, but the idea had potential. Even Adobe did a similar project that never saw the light (it was called Adobe Thermo, then Catalyst and it died with Flex).
Why Qualcomm’s Potential Quantum AI Advantage Could Be Huge

A friend of mine worked in the US for 17 years under various visas, but never managed to get her green card. She is facing retirement without the social security she was taxed to fund. She also won't get anything of usable value from the old-age pension program in her country of origin since she worked out of country for so many years. A real immigration trap.
I've heard the argument from a few chip designers that the main thing the user microprogrammable machines got you was a Harvard architecture. You got most of your wins by pushing complex ideas into ucode where each step fetched from the ucode ROM instead of the main memory bus. That's why on pretty much every microcoded machine you see a memcpy instruction. It's the most obvious win for getting the ifetches out of the way of your data throughput.

Once we started adding instruction caches, that big win started to not be as big. Ultimately it's the caches that killed off that machine, and the ucode interpreters you saw on the Smalltalk and Lisp machines.

One idea I would like to make it's way from ucode that hasn't yet though is being able to define interrupt boundaries for the real time tasks you allude to.
Ask HN: Good/bad idea – universal API for cloud app datasets?
My background is as a software engineer at SMBs and startups, which typically lack a data scientist. Because I love numbers, charts, etc. I do a lot of amateur data science. I enjoy the analysis, but I despise the data preprocessing: it's common for an SMB to store data across 10+ cloud apps (Salesforce, Google Ads, Hubspot, Mixpanel, etc) but it's uncommon for them to store this data in a data warehouse. This means I need to learn each app's API and write scripts to fetch data, transpose data, set proper data types, handle schema changes, network errors, etc.

I'd love an API like `sklearn.datasets`, but for cloud apps, so I'm thinking of creating one. For example, if I wanted to fetch Saleforce contacts, I'd simply call `petaldata.Salesforce(API_KEY).contacts().to_frame()` to load contacts into a Pandas Dataframe with proper types.

Good/bad idea? This would be for folks that aren't ready for a full ETL pipeline + data warehouse but want to dig through their data and experiment with ML algorithms quickly.

I actually agree with you. I think that the best way to deal with the problem isn't to censor the marketplace of ideas, but to fix the political system

Why would one believe such a silly thing? If I heard a doctor was accused (or even convicted) of shoplifting that wouldn't ruin the credibility of the lives they have saved. If Galileo was also a racist and a murderer that wouldn't reflect poorly on heliocentrism (although he probably wouldn't have a satellite navigation system named after him).

Even if Assange had violently raped and murdered multiple people (which would absolutely make him a terrible person) how would that affect the credibility of his civil work in any way? Does it make the truths that he helped expose any less true?
I live in the UK. Can't say I agree with you. Especially because I have a mobility impairment. The Uber drivers are always more willing to help, (I'd imagine thanks to the rating system), stop exactly where needed etc.

Yes, I know. In the end, you can't cover things 100%. I have made my preference very well known to my friends and family, though, and they have respected it so far to the best of my knowledge.

I will admit, though, that I do try to avoid having my picture taken by anybody for any reason if I can possibly do so.

Social media has made it too dangerous to engage in blind trust about these things anymore.

Light weight satellite construction will still be a very high priority because making the structure of the satellite lighter extends its operational lifespan.

The reason is attitude control. Reaction wheels can be used to orient the satellite, but eventually reaction wheels get saturated. At that point you need to use thrusters to cancel out the reaction wheel saturation. Those thrusters require propellant, e.g. something to push against. The greater the ratio between propellant mass and structural mass the satellite has, the longer it can remain operational before the propellant runs out and your reaction wheels finally saturate, leaving your satellite tumbling useless without attitude control.
> Make the culture of your company so awesome that people will want to stay, even if you can't pay the most. Make mentoring/growth a central strategy at every level so people will see a path to grow.

I think this only goes so far. There are better companies and worse companies, sure, but even the best companies have their issues and after enough time, most people want to move on. People also change, and what seems awesome to a fresh graduate may not be great for someone older, so it's always hard to keep everyone happy.

Pay, however, seems to be a motivator that keeps a lot of people in place (certainly not everyone, but a lot). I know plenty of talented people who feel trapped at their jobs because their jobs pay very well. It's common enough that there's a term for it, "golden handcuffs".
Hidden messages inside consumer products aren't bad, for example what Microsoft put inside the Zune HD and I believe Nintendo has also done it a few times.

Except.... Some engineer thought it was prudent to put "Big Brother is watching" inside of a preproduction unit. Why? That seems incredibly tone deaf of the problems and criticisms Facebook has experienced. Is it supposed to be satire? Facebook "watching" users was a legitimate concern people brought up during their acquisition of Oculus, and the main reason I went with Vive (and didn't install the viveport software)

We use separate channels for different projects and people join/leave as needed. @here is incredibly useful when you have a general question and not sure who might have insight.

It all boils down to how people use the communications channel. I see @here multiple times a week but do not feel like it is a big distraction. At worst it can create a few minutes of distraction from my current workflow and if I'm truly in the middle of a thought process I ignore the message for a little bit or unless a 2nd notification hits.

$300K to live on the west coast is really not that appealing to someone who is living in a major city, with the stereotypical house in the burbs in a good school system with 2.1 kids where on the higher end you can make $150K to $160K as an architect/team lead/principal. Especially if you are married with two incomes where you can easily put the lower income completely toward increasing net worth or cash flowing your kids college expenses.

Engineers getting paid $300K could easily be the stereotypical r/cscareerquestions “learn LeetCode and work for a FAANG” type graduating from college.

This question will produce absolutely no valuable answers without providing at least a bit of context.

What are you trying to accomplish? What problems are you facing? What do you intend to do with this budget?

You can hire 100 code monkeys and have them accomplish _anything_ just to say you spent the budget, or you can provide rigid leadership in a certain direction. It's up to you to decide whether they succeed or fail.
I disagree. The progress of camera and laser technology, in addition to AI, is improving at an incredible rate. The market for self-driving vehicles is huge -- any company that figures it out will make billions (maybe trillions).

Computers can have a perfect 360 degree view and track and categorize every object around them. Humans will be both physically and intellectually outmatched eventually. And humans just aren't that good at driving on average.

EDPB guidelines on the processing personal data by online services
Agreed, "My DNA is my personal property," is a weak argument.

"My DNA is my personally-identifying data," is a better one.

The question of what rights we have to our personally identifiable information is not yet answered fully, and the debate is an important one (e.g. consider GDPR and the "right to be forgotten").

Data's worth is recognized today by those who are harvesting it from us. The mountains of data which only a few multinational corporations can gather and store in globally-distributed data centers are imperative to machine learning and the artificial intelligences they are making, which will soon direct a great many of our daily conveniences at potentially great profit to them.

So it is important for us to today define what rights we demand to such a valuable resource, which is created solely by, and living within, the only item any of us has true natural possession of: our very bodies.
Under EB5 you can get green cards for the wife and kids too so probably there were 2400 investments of $500k and 800 spouse/kids. There is no motivation to invest more than the minimum as there are quite a lot of strings attached. Something like 98% of the investors are Chinese. I looked at doing it myself - its actually not a bad deal if you want a green card and have the money.

> I think the problem is largely isolated to companies in decline or stagnant -- which unfortunately is most companies.

I don't think that's the case at all. I think it's just that typical corporate culture (in the US at least) is not accustomed to giving large internal raises to employees based on increases in that employee's market value.

Most companies base their annual compensation on giving people a few percentage points for cost of living adjustment, then a few more percentage points based on performance. They standardize those numbers so they can say, 'you did average, you get 4%' 'you did great this year, you get 6.5%'.

Many, many companies don't factor in at all that employee value on the market can increase much, much faster than 2-8% per year. Even companies making money hand over fist. The usual way of approaching annual raises is wildly unsuited for compensating talent that is in high demand.

You act like you’re doing them a favor by hiring them. You’re not. You’re trying to get cheap labor, and expecting them to feel indebted to you and work at below market rate. It’s not going to happen.

Pay them cheap during training. After they’re trained, pay a premium to the ones you want to keep. Let the rest go to a competitor. It’s simple.

If you can’t afford that, that’s a problem with your business, not the employees.
> f there is already an selection, the click causes the start or the end of the selection to move to the site of the click, which is behavior I've not seen in any other GUI

Emacs does that in X11 because that is (or at least was) the standard behavior for text selection in X11. Emacs is simply conforming to the environment it is running within.
200GB? Are you sure about that?
I have pretty decent credit so this is something I have quite recently begun to look into as the rates seem decent enough. Anyone with experience I would love to hear from.
why are you falsely assuming it all needs to be reviewed? it only needs to be reviewed if it's flagged. each additional flag on the same vid should double the likelihood that the material is objectionable. The question is how much video is actually flagged, and what percentage of those reports are false? Even that's an easy problem to solve, because if the same accounts keep flagging clearly-not-objectionable content they can just be muted.
> - Font rendering.

Worth double-checking, but I think that's one area Mituharu's is better than standard Emacs. I definitely recall some font rendering issues with some past version.

As for your other points, they aren't resolved. FWIW, I work around them:

> The server mode compatibility

I just have one long-running Emacs session. I have some colleagues who have experimented with using a launchd LaunchAgent to start emacs server in the background when they login. I haven't kept up with their results and I don't know if there are any side-effects.

> "Windows" (or Frames?) have generally not worked seamlessly for me

Since I have a long-running session, this isn't much of a problem for me. That said, when I do start up Emacs on first login, it indeed takes upwards of 5 seconds to startup, including a window re-themeing and resizing. It's not great, but like I said, it's only once at startup for me. Furthermore, because I came from a tiling window manager on Linux (AwesomeWM), I required similar behavior on macOS. I use SizeUp [1] with shortcuts configured to move my windows to side/corners of the screen. It's far from being as good as a true tiling window manager, but I've had to be satisfied with what I can get.

The general model of what a black hole looks like is well understood. The highest definition rendering is that in Interstellar, except for one side being brighter than the other due to the relativistic beaming. They kept that part out of the movie to just make it look nicer.

All the models are the same, and the real picture is "blobby" only because of the process in how it was taken. I think you are refusing to accept that but there's nothing else to say about it. It wasn't a direct photo, it was a complex assembly of several different radio telescopes around the world stitching data together. If we were actually next to it, it would very much look like the one from interstellar.

The video you linked isn't about the prediction being wrong, more that he just didn't expect to really see a black hole at all. Even though black holes are generally understood for decades, there's a certain shock and awe to seeing it real for the first time.
I appreciate your desire for a better hackernews community, but I disagree with your assessment of my comment. The article is clearly for marketing, not quality content. The original poster is indeed a member of the company. That's not to say company articles are all bad, but the merit of this article is what I based my comment on. But to be fair, what I consider "bile spewing" is based on reddit quality comments, so perhaps I should rethink my commenting style.
I'd say that medium sized sites are more troublesome in that regard. Once a site has grown big enough to become cumbersome for one person to manage, but not large enough for most to justify staff, then you have an issue. There shouldn't be any excuse for a small site to fall behind with updates, etc... It's simple.
Based on my limited testing, a VM running on a NTFS file backed disk runs just as fast natively.
>I agree there were past issues,

Are there current issues as well? [1][2]

A main point is this (and I think its been mentioned elsewhere in this thread as well):

An attack on the status-quo is not a promotion of socialism

Our current implementations are a far cry from a free market. The entrenched powers and corporations don't want free markets-- its socialism for the rich, capitalism for the poor [3] [4]

We'd have to start from scratch to attain a free market. And even then, the oft-quoted invisible hand of competitive markets falls flat in an increasingly opaque, complex world [5]

It seems to me that you have a strong sense of what is fair. I urge you to look out into all the wealth of information we have and take a hard look to see if our current way of being is fair [6][7]

we didn't backdoor the encryption. instead, we specced how clients could securely pass attachment keys to an AV server, if they need to. but in practice none of them (other than the french app) do.

the whole point was to spell out that we haven't backdoored the encryption, and instead been transparent about how content filtering could be done in the most responsible manner, if it's really needed.

Those can be wrong though. I've been locked out of accounts because they said I incorrectly answered questions about myself (as if they know better than me) and it took weeks and multiple hand-written letters and a physical trip to an office to get it fixed.

The assumption that you have, that the system "just works" is awful. Because when it turns out the system actually doesn't work, it's a fucking clusterfuck just to get someone to listen to you because they don't believe you are who you say you are, and government issued ID is apparently insufficient.

And the government seems to think I am the same person as my deceased father and grandfather because we share a name, and holy fuck is it frustrating come tax season (I have never in my life had my taxes accepted the first try and have had to physically visit the IRS before) or any time anybody tries to do any sort of background check on me.

None of which are actually "uniquely yours", because everything we know to date about fingerprints or faces or DNA is that there is a low probability of collision with someone else having those same attributes, but it's not zero probability.

Somewhere, somewhen, there is likely to be another person who has a face, or fingerprints, or snippet of DNA that cannot be distinguished from yours within the accuracy of the tools we have today.
