  • If it’s part of the Requirements that the frontend should handle “No results found” differently from “Not authorized”, even if that’s just by showing an icon, then ach list of stuff which might or not be authorized should have a flag signalling that.

    (This is simply data analysis - if certain information is supposed to be shown to the user it should come from somewhere and hence the frontend must get it from somewhere, and the frontend code trying to “deduce it” from data it gets is generally prone to the kind of problem you just got because unless explicitly agreed and documented, sooner or later some deduction done by one team is not going to match what the other team is doing. Generally it’s safer just to explicitly pass that info in a field for that purpose to avoid frontend-backend integration issues).

    Authorization logic is almost always a responsibility of the backend (for various reasons, including proper security practices) and for the frontend it’s generally irrelevant why it’s authorized or not, unless you have to somehow display per-list the reason for a it being authorized or not, which would be a strange UI design IMHO - generally there’s but a flag in the main part of the UI and a separate page/screen with detailed authorization information - if the user really wants to dig down into the “why” - which would be using different API call just to fill in that page/screen.

    So if indeed it is required that the frontend knows if an empty result is due to “Not Authorized” rather than “No results found” (a not uncommon design, though generally a good UI design practice is to simply not even give the user access to listing things the user is not authorized to see rather than let the user chose them and then telling them they’re not authorized to do it, as the latter design is more frustrating for users) that info should be an explicit entry in what comes from the backend.

    The JSON is indeed different in both cases, but if handled correctly it shouldn’t matter.

    That said, IMHO, if all those 3 fields in your example should be present, the backend should be putting a list on all 3 fields even if for some the list is empty, rather than a null in some - it doesn’t matter what the JSON is since even at the Java backend level, a List variable with a “null” is not the same as a List variable with a List of length 0 - null vs empty list is quite a common source of mistakes even within the code of just the one tier, though worse if it ends up in API data.

    Who is wrong or right ultimately depends on the API design having marked those fields as mandatory or optional.


  • That sounds like an error in the specification of the client-server API or an erroneous implementation on the server side for the last version: nothing should be signaled via presence or absence of fields when using JSON exactly because, as I described in my last post, the standard with JSON is that stuff that is not present should be ignore (i.e. it has no meaning at all) for backwards compatibility, which breaks if all of the sudden presence or absence are treated as having meaning.

    Frankly that there isn’t a specific field signalling authorized/not-authorized leads me to believe that whomever has designed that API isn’t exactly experienced at that level of software design: authorization information should be explicit, not implicit, otherwise you end up with people checking for not-in-spec side effects like you did exactly for that reason (i.e. “is the no data being returned because of user not authorized or because there was indeed no data to retunr?”), which is prone to break since not being properly part of the spec means any of the teams working on it might interpret things differently and/or change them at any moment.



  • If I remember it correctly, per the JSON definition when a key is present but not expected it should be ignored.

    The reason for that is to maintain compatibility between versions: it should be possible to add more entries to the data and yet old versions of the software that consumes that data should still continue to operate if all the data they’re designed to handle is still there and still in the correct format.

    Sure, that’s not a problem in the blessed world of web-based frontends where the user browser just pulls the client code from the server so frontend and backend are always in synch, but is a problem for all other kinds of frontend out there where the life-cycle of the client application and the server one are different - good luck getting all your users to update their mobile apps or whatever whenever you want to add functionality (and hence data in client-server comms) to that system.

    (Comms API compatibility is actually one of the big problems in client-server systems development)

    So it sounds like an issue with the way your JavaScript library handles JSON or your own implementation not handling per-spec the presence of data which you don’t use.

    Granted, if the server side dev only makes stuff for your frontend, then he or she needs not be an asshole about it and can be more accomodating. If however that data also has to serve other clients, then I’m afraid you’re the one in the wrong since you’re demanding that the backwards compatibility from the JSON spec itself is not used by anybody else - which as I pointed out is a massive problem when you can’t guarantee that all client apps get updated as soon as the server gets updated - because you couldn’t be arsed to do your implementation correctly.


  • Around here, Portugal, were every Summer the temperature exceeds 40 C for at least some days in August, we have outside rollup shades on every window, so one of the tricks is to keep the shades down and and the windows closed during the hottest and sunniest parts of the day, at the very least the afternoon.

    Then at night you open the windows and let the cooler night air in (even better if you do it early morning, around sunrise, which is the coolest time of the day).

    Note that this doesn’t work well with curtains or internal shades, because with those any conversion of light into heat when the light heats the shades/curtains (as they’re not mirrors and don’t reflect all light back) happens inside the house and thus that heat gets trapped indoors.


  • I’m sorry but unwaveringly supporting a nation ruled by ethno-Fascists when they’re committing Genocide because of the ethnicity of the majority and the leaders there is the same old extreme racism as in the old days and passing laws to punish anybody who criticizes that ethno-Fascist nation is the same authoritarianism in defense of Fascists claiming to represent an ethnicity as in the old days.

    If the mindset that was the foundation of Nazism had changed in Germany we would neither be seeing such an extreme version of supporting a regime that claimes to be supporting some people because of their ethnicity (even against the will of many of those very people, who again and again point out that Israel and the dominant ideology there does not represent them), nor would be we be seeing the use of the Law to force everybody else to either go along with it or shut up.

    A Germany where the power elites had learned the Humanitarian take of “never again” (i.e. “never again shall this be done to anybody”) rather kept the racism going and hence using a racist version of it (i.e. “never again shall Germans do this to Jews”), would not be doing this, not even close.

    What’s going on in Germany is not merely “crushing guilt of what happened in WWII”, it’s the racism and authoritarianism coming out of hiding with the excuse that “It’s for the Jews rather than for the Arian Race, so it’s alright”.



  • I still remember well how the New Labour faction, in order to attack Corbyn, deemed him an anti-semite by association because in a conference he sat on a panel with a guy who compared the actions of Israel to those of the Nazis. Turns out said guy was a Jewish Holocaust survivor, so they they were saying that a Jewish Holocaust survivor was an anti-semite in order to slander Corbyn by association.

    Also quite a lot of Israel-linked “Jewish” associations cooperated in that whole campaign of slandering Corbyn and Labour as “anti-semite” (remember how the Labour Party was said to have “many” anti-semites, and they turned out to be in a lower proportion than society in general and way less than the Tories) to bring Corbyn down and replace him with somebody from the New Labour faction, which succeeded.

    The New Labour leadership has quite the debt to the Zionists for that, so don’t expect them to be any less unwaveringly supportive of a genocidal ethno-Fascist Israel than the Tories - at best it’s going to be like Biden in American: claim to want Bibi to stop all the while by action de facto supporting him.





  • Well, since I will also browse Lemmy quite literally “at Work” it makes sense to check the Profile option that blurs the Not Suitable For Work stuff even if having the Show NSFW content also ticked.

    Explicitly going back and forth changing the option depending on where you’re accessing Lemmy from is a recipe for mistakes, at best embarassing but, depending on where one works, which can go all the way up to being fired for cause.

    That’s the rational take and I’m sure plenty of people will vote Biden following that rationale.

    The top poster’s “pestilence is a good thing” (i.e. Biden is a “good guy”) statement on the other hand is insanelly tribalist and pure fantasy.

    Being a Lesser Evil by comparison with an extremelly Evil option is not at all the same as being Good.

    Lots of talk, no action: that’s bullshit Political Propaganda 101 when a politician in power wants to do something which most of his voters are strongly against.

    His Administration’s actions are exactly the opposite, from the weapons shipments to Israel going around Congress that included 2000lb bombs to UN Vetos and saying that the ICJ shouldn’t even be evaluating the case against Israel for Genocide (clearly this Administration fears a veredict of “guilty”, which means they do believe Israel is likely comitting what amounts to Genocide under International Law).

    The non-sociopath path for America would’ve be “Perfect Neutrality” (no action at all), yet Biden choses actual military and diplomatic support, including condemning anti-Genocide demonstrators as “anti-semitic” and condoning the use of police violence against them all the while in this specific subject lying just as shamelessly as Trump.



  • Also a lot of the late Soviet Union military technology came from Ukraine, plus their military were also trained in the same kind of school of thought as Russia and still know it.

    So it makes sense that, when push came to shove, the Ukranians would fast come up with asymetric war solutions against Russia, that Russia wouldn’t be as fast in effectivelly countering them and Ukraine would be quicker at developing new or adjusted solutions once Russia found a counter (or, more generally, that Ukraine would remain ahead of Russian in the cycle were each side develops a counter to the other side’s counters).

    Had Russia’s initial blietzkrieg attack worked, it would’ve been a different story, but at this stage it makes sense that Ukraine has the technological edge, not just in the weaponry it gets from the West but also in their own weapons development, especially now that it has much better AA to protect the installations far away from the frontlines working on weapons tech.

    I’ve noticed that the loudest the politicians in a country rant about how great a Democracy that country has, the less of a Democracy it is.

    In Europe, for example, you get British Politicians going on an one about how the country has the “Oldest Democracy in The World” (this in a country with a King who a few years ago - well, his mother - was found to actually have some power over what legislation gets passed, an unlected second chamber with members who inherit their seat from their parents and First Past The Post for Parliament) all the while in The Netherlands (who, IMHO, have probably the most Democratic system in the World, including Proportional Vote, though with a powerless King) politians pretty much never rant about the quality of their Democracy.

    At least in the West, the most loud and relentless proclaimers of how great their Democracy is by a large margin are American politicians.
