echo -n is not safe, because some versions of echo will just print "-n" as part of their output (and add a newline at the end, as usual). In fact, XSI-compliant implementations are required to do this (and the same for anything else you try to pass as an option to echo). According to the POSIX standard[1], "If the first operand is -n, or if any of the operands contain a <backslash> character, the results are implementation-defined."
Thanks - I wasn't aware that echo was that problematic as I target bash (usually v4 and above) from my scripts.
I just tested it out with:
sh /bin/echo -n "test"
/bin/echo: 3: Syntax error: "(" unexpected
I didn't realise until recently that printf can also replace a lot of uses of the "date" command which is helpful with logging as it avoids calling an external command for every line logged.
"Others still have reported that the internet outage could be circumvented by connecting through a virtual private network (VPN), giving a hint of where the wider problems lie, and suggesting that Virgin Media’s outage, like that at Facebook in 2021, may have been the result of a flaw in the deep-level routing systems that allow internet services to connect to each other."
In no part of the news article mentioned they were actually admitted into the building. They were just standing around outside in the cold waiting for who knows how long. Nothing happened. This is literally about nothing.
I empathize with those remaining with a H1B, they would be worried sick. They would have less choices and would otherwise have less of 60 days to find a new job or to leave the country.
I think we are missing some contexts here. I have been trying to find more information about them. From what I found [1] (hopefully accurate) it looks like they are a new team - Beta in August 2021 and just incorporated in this February.
The founder/CTO is a full stack developer. I speculate they are a very small team (1-2 developers at the most) and a relatively straightforward architecture. In that context I suspect it is quite feasible to go from local to production without going through staging: They are likely to have a self sustained stack that can be packaged; they don't have a huge database or collection of edge cases; they have few customers, low expectation in terms of service level; they don't have stakeholders to review and approve features done (they are their own bosses). I emphasize with where they are, I have been in the same place at some point. It will be interesting to see whether this is sustainable without staging, or for how long, as they grow in team and offering.
