Yeah that's the most surprising part. And the pricing uses the wrong symbol order for US pricing, not sure about other locations: 49$ instead of $49
- rob74 4y ago
  Yeah that's the most forgivable part ;). I never understood this particular idiosyncrasy - after all you don't say "it costs dollars three", and you also put other units of measure after the value, e.g. 80 mph, 100 °F, so why on earth does the dollar sign have to go before the amount?
  - davnicwil 4y ago
    Wow, you're right! It's crazy how you can go your whole life never noticing or thinking about something like this that is so clearly irregular, just because it's the way you've always seen it or thought about it. I thought for a few minutes about the reason that units of currency are different and come before the number, determined there must be an obvious logical one. But, if there is, I can't think of it!
    - tbossanova 4y ago
      I think it’s so you can fit the cents symbol at the end e.g. $6.75c - but this isn’t really used anymore so the dollar sign at the front is a bit of a historical anomaly at this point.
      - sverhagen 4y ago
        Honest question, was it ever used in that combination? I've seen ¢ used for amounts less than a dollar, e.g.: 75¢. I (still) sometimes use it like that, because, I guess, it makes me feel adjusted to my environment, as an ESL :-) But I've never seen both $ and ¢ in the same amount/expression.

        6.5' vs 6'5" vs 6'5 ?
        elygre 4y ago
        Isn’t 6.5’ six and a half feet, i.e. 6’6”?
        jbverschoor 4y ago
        Well, exactly
        davnicwil 4y ago
        Ah, so I also don't think I have seen this in practice, but I suppose it's possible that it originated from pre-decimal-system currencies, like the old British money system, where perhaps it was more important to use separate units for clarity. I suppose it's also possible it needs to sometimes be used (although, again, I have never seen this) in certain cases in more 'formal' situations - accounting, contracts and so on. I guess the format, with the symbols wrapping the numbers so as to make them easier to parse, does make sense.
  - rrrazdan 4y ago
    Yeah even if we consider USD a unit, most units are appended after the number. It is weird. Never thought of it this way. Huh!
  - throw101010 4y ago
    It makes it harder to modify amounts on checks and accounting entries. 100.00$ could more easily be turned into 1100.00$ than $100.00. It comes from a time when we did still write a lot of amounts by hand.
    - elevaet 4y ago
      Oh that is a really good explanation, thanks! I've always wondered why we do this.
    - Hamuko 4y ago
      I wonder if the relative lack of popularity when it comes to cheques is the reason why the Euro symbol (€) is added after the number.
      - Tijdreiziger 4y ago
        It's added before the number in (at least) the Netherlands.
    - briHass 4y ago
      Except that for checks, it's not the numerical part written in the little box that matters, it's the full written amount e.g. 'Five Thousand Three Hundred Fourty-Seven and 33/100' for 5,347.33. Similar rationale, though, because it's easier to modify a number (say, change a 7 to a 9) than to change a full word.
    - yourad_io 4y ago
      I thought that in checks we surround the amount with hashes: #$105.90# Is this just local to me?
  - eesmith 4y ago
    The only exception I could think of was R-values, eg, "Vacuum insulated panels have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch." , quoting https://en.wikipedia.org/wiki/R-value_(insulation)#Example_values https://en.wikipedia.org/wiki/R-value_(insulation)#Example_v... . From the same source, "an R-value expressed in I-P (inch-pound) units[13] is about 5.68 times larger than when expressed in SI units"; the latter being measured in K⋅m2/W.

Is the "Most popular" badge on pricing page something actually measured or do people just stick it to whatever option they prefer users to buy?
- berry_sortoro 4y ago
- 130e13a 4y ago
  that's something i keep wondering about as well. i think it depends on the reputation of the company/project. some of them probably do attach it to the option that is actually most popular, but i'd guess that most of them do not. for example, if a thing has three pricing options (free, paid, and enterprise), it is always the second option (paid, but not enterprise) that has the "most popular" badge. which seems suspicious to me in cases where the free version is sufficient for most users and as a result there isn't really much of an incentive to switch to a paid plan.
  - hnbad 4y ago
    It's a self-fulfilling prophecy at best. I don't think anyone[0] actually marks pricing plans by what's actually most popular. The idea behind these callouts is to direct people away from the lowest tiers. According to theory, some buyers will always go for the priciest plan because they want "the best of the best" but most will try to get the best value for their needs. A common trick is to have a slight price increment between the bottom and middle tier and then a large increment between that one and the top tier because this suggests that you're leaving money on the table by going for the cheapest option. As an approachable example consider McDonald's McNuggets sizes where the smallest size has a noticeably higher cost per nugget than the next one up. It's a bit silly in this case as an organization plan has a different target audience from a personal plan but to me this suggests the license works in such a way many organization end up buying only a single personal plan because the organization plan doesn't provide any added value beyond allowing multiple developers to work with it. A common pricing strategy is to either only have two plans (free/paid or personal/organization) with easily distinguishable value propositions or to have multiple pricing tiers (e.g. basic/premium/professional plus a de-emphasized free/minimal "trial" plan and an option to get a custom offer for enterprise) with only the latter strategy normally having these callouts. If a company does use "most popular" based on actual popularity, they'll likely only do so when the most popular option is the one they actually want you to pick anyway. [0]: To be fair, a few years back I once came across a pricing page that had tons of plans and did distinguish between "most popular", "best value" and such. But this is a rare exception and I still don't think they actually measured that one.

The license seems a bit ambiguous. $49 for a "one user license", I hope that really means "one developer"? But one developer can build an app used by many users. So I suppose you are oddly pressured into buying the more expensive license because you probably have more than one "user"? Generally, I feel uncomfortable investing in source-available tools. That said, if I needed a PDF viewer in a React app in a pinch, I'd probably reach for this and pay for the full license. More details on the license found here: https://react-pdf-viewer.dev/license/ https://react-pdf-viewer.dev/license/ This is the part that would freak out most lawyers: "You may combine the Item with other works and make a derivative work from it. The resulting works are subject to the terms of this license."

It clearly says "Use in multiple websites" under both licenses, so it's talking about devs not users (like most such licenses).
