Description

A Discussion about the Technical Challenges of Maintaining Existing Software Systems vs. Developing New SoftwareWorking with legacy code for software systems presents added difficulties and challenges for programmers because often legacy code was not written to support automated testing and it is likely that the codebase has deteriorated with changes and modifications over time. Thus, not only is maintaining existing systems demanding, challenging and costly, but maintenance efforts can fail to satisfy users and result in further deterioration of codebase.

Working with legacy code for software systems presents added difficulties and challenges for programmers because often legacy code was not written to support automated testing and it is likely that the codebase has deteriorated with changes and modifications over time. Thus, not only is maintaining existing systems demanding, challenging and costly, but maintenance efforts can fail to satisfy users and result in further deterioration of codebase. Software redesign has the capacity for presenting real improvements and a redesign is cheaper when compared to cumulative maintenance efforts undertaken over the years. However, it is also important to understand that new software will start aging soon after completion and this means that ongoing maintenance is required. This essay presents a discussion about the technical challenges involved with maintaining software compared to the challenges involved with the design of new software.

Doesn’t spray!
Size: 5 Fl Oz (Pack of 2), Style: SPF 30
So there is a barely visible lock/ unlock icon on the plastic strip under the spray nozzle. Turn the nozzle to unlock, and it should have sprayed. NOPE! I had to put the can on my bathroom counter and press as hard as I could to get the spray to come out and into my other hand. I then applied the lotion. It’s ridiculous how hard this is to use! So I can’t comment on the sunblock itself because it’s next to impossible to use it as a spray. Cannot recommend this product until manufacturer fixes the faulty nozzle.

Great sunscreen!
Size: 6.7 Fl Oz (Pack of 1)
We have used this sunscreen lotion on multiple beach vacations, and most recently on our cruise. The quality, coverage and protection are great. The lotion glides on smoothly and is not sticky. It has a light fresh scent that did not irritate the members of the family with sensitive skin. This is one of our favorite lotions to use, and we keep repurchasing it. The price point is great as well.
