First, I'd like to highlight my personal premise on error handling approaches in C++ (as it might be the source of confusion in the first place). C++ Standards, 2004 (Sutter, Aleksandrescu), item 68 states as follows: Use assert or an equivalent liberally to document assumptions internal to a module (i.e., where the caller and callee are maintained by the same person or team) that must always be true and otherwise represent programming errors (e.g., violations of a function's postconditions d...| Recent Questions - Software Engineering Stack Exchange

We want CI/CD to inject the production connection string into a .NET Framework app.config during deployment. In source control, we only want test/staging DB connection strings. Developers should still be able to debug locally with test/staging DBs. At deployment, the CI/CD pipeline should replace the connection string with the production one (stored in GitHub Secrets). Question: What’s the recommended way to update or override app.config connection strings in a GitHub Actions workflow for a...| Recent Questions - Software Engineering Stack Exchange
Most database wire protocols mandate a specific byte order for multi-byte integers: PostgreSQL: big-endian (network byte order) MySQL: little-endian MongoDB: little-endian (BSON format) OracleDB: Oracledb uses big-endian for vector data (link) However, this seems inefficient. For example, when both client and server run on x86 (little-endian), PostgreSQL still requires: Client converts from little to big-endian Sends over network Server converts from big to little-endian Stores in native form...| Recent Questions - Software Engineering Stack Exchange
I am building an Android password management app, where passwords are locally kept for security reasons. The network endpoints are only for creating an account, email verifications etc. I want to handle a scenario where, if a user accidentally deletes the app and re-installs it, the local data is backed up for that account. Of course I don't want to implement a cloud backup here. What is the best way to locally and securely backup the data of passwords, only so that upon reinstalling the app ...| Recent Questions - Software Engineering Stack Exchange
In my working experience, I am into a situation in which the team has stopped using migration scripts for setting up the db. The team is fast paced focusing on business upon a 1-year old startup. Currently, we are using schema diffs provided from doctrine and db dumps (from deployed dev or staging environment) for local development. But there are situations that beyond only running a schema diff is not enough such as this situation. So what is the most common approach in this problem?

Lately, I’ve been studying the fundamentals of Software Architecture for web applications, and I’m a bit unsure about how the data and presentation layers should interact. From what I understand, the presentation layer is responsible for operations like validating requests, handling authentication, and so on. Meanwhile, the business logic and query handling should live within services or, in some cases, dedicated queries and commands. My question is about data serialization and transmissi...| Recent Questions - Software Engineering Stack Exchange
I’m integrating with the Ajax Enterprise API which exposes an AWS SQS feed for device events and notifications. The API documentation is here: Ajax Enterprise API Docs. Each SQS message supplies an event code, which is then used to look up the corresponding log message. This is supplied with placeholders, which you then substitute with other data in the SQS message. Example: "M_01_20": "%3$s: open, %1$s in %2$s" -> "MyHub: open, MyDetector in MyRoom" In an ideal world the feed would just su...| Recent Questions - Software Engineering Stack Exchange
I'm testing writing 10 MB of data to a server. The expected result echoed back is 10485760 bytes. 160 writes of 65336 bytes. Approximately 1 of 5 tests I get back 10420224 bytes in the test. 65536 less than the expected 10485760 bytes.

For me the hardest part has always been designing data access layer.

There is already a prior question dealing with why certain bit-widths were chosen (although I do find it somewhat insufficient, but that's another topic), but what strikes me as unusual is how the bits are distributed rather than anything else. If we are to divide a 32-bit, single-precision floating point number into bytes, we see that the exponent is split across bytes 3 and 4, with one bit in byte 3 and seven in byte 4. There are various "homebrew" floating point libraries around online tar...| Recent Questions - Software Engineering Stack Exchange
I am creating a DB that indexes JSONs on top of a key value storage engine (LMDB or somewhat similar). When a new JSON needs to be indexed, I will create an entry for each field (AKA, JSON key), for example, for the field "firstname=123" I will create a reverse index "123 = jsonid". So this allows me to query all json objects in which firstname equals 123. My question is, how do I structure my indexes, in order to be able to answer a compound query (example firstname = X and lastname = Y) In ...| Recent Questions - Software Engineering Stack Exchange

I'm a huge believer in the value of Intellisense for showing you what syntax is expected and allowed (and also saving typing, though this is a secondary consideration). When you build a web component (or use JSX or tagged templates or the like), you have code like this: class MyElement extends HTMLElement { constructor() { super(); this.innerHTML = `<span>${this.getAttribute('name')}</span>`; } } and this is nice in terms of getting typescript/javascript Intellisense: But it's terrible in ter...| Recent Questions - Software Engineering Stack Exchange
In microservice architecture, let's say I have 4 services that will need file upload/download feature, I have two options for this: I can create a new 5th service to expose a file upload/download API.

Not sure how to handle this. Our current app (.Net MVC) is accessed via companyname.appname.com, authentication is handled via forms (cookie) authentication. Within the app there is a global search box that is quite heavily used, we are looking to split this out into it's own microservice so all calls for search will go to something like search.appname.com instead, therefore lightening the load on the main app. The question we have is about how best to authenticate the calls to that url.

So I've developed a website for a client, however he used to use this url with a re-direct to 'another' site of his. I had the re-direct cancelled, but whoever visited their old website before, still has it in their cache that it redirects to the old site. This can be solved by a browser cache clean-up, but I was wondering if there was another way of solving this. Especially because I do not think my users will understand what "clearing the cache" means (target demographic is age 60+).| Recent Questions - Software Engineering Stack Exchange

I think I generally know what the Garbage Collector in Java does, but It's praised a lot, so I thought maybe I'm missing something about it's functionality. What I know is, that the GC takes care of erasing from the memory objects that have no reference to them, and thus are unreachable by the programmer. For example, if inside a loop I'm constantly creating a new Object(), the previous ones will eventually get deleted by the GC (correct me if I'm wrong). This is very useful for me as a Java ...| Recent Questions - Software Engineering Stack Exchange
After reading lots of pages on various sites, I came to the conclusion that abstract data-type (ADT) helps to separate the use of a data-structure from its implementation. We can easily map the data into a data-structure by using an already available abstraction. And this abstraction is called ADT. Please tell me if I have understood this correctly. Also if you can give a small example, it will be very helpful. If you prefer to give any code in your example, C or Python would be helpful for m...| Recent Questions - Software Engineering Stack Exchange
