One common error is poor physical security around the access control components. If the card readers or keypad devices can be easily tampered with, it's a huge risk. Another is not having a backup system in case the main access control system fails. Imagine a power outage and the doors are all unlocked because there's no backup. Also, if the access control software has bugs and they are not fixed in a timely manner, it can create holes in the security. For instance, a bug might allow someone to bypass the authentication process.
One common mistake is not monitoring resource usage. If you don't keep an eye on what resources are being used and how much, you can end up with unexpected bills. For example, leaving EC2 instances running when not needed.
Using the wrong product. For example, if you have dark hair and use a bleach meant for light hair, it can cause serious damage. Also, leaving the color on for too long. This often happens when people are distracted or misread the instructions.
Inaccurate cost assumptions are also a big part of DCF horror stories. Sometimes, the DCF model doesn't account for all the costs associated with a business. A manufacturing company might not factor in the rising cost of raw materials over time. So, the projected profit margins are much higher than they will be in reality, leading to a misvalued company according to the DCF.
A frequent error is overwriting data without realizing it. For example, when someone is in a rush and they start typing in a cell that already has important data. Also, problems with sorting and filtering can lead to 'horror stories'. If not done carefully, it can mess up the order of data and relationships between different parts of the spreadsheet.
One common mistake is lack of market research. Just like in the example I mentioned earlier, not understanding the target market can lead to disasters.
A major error in 'cfd horror stories' can be improper domain sizing. If the computational domain is too small or too large compared to the actual physical problem, it can cause problems. For instance, if the domain is too small for a flow problem, it might not capture all the relevant physical processes, leading to wrong results.
Often, there is a problem with the testing environment not being accurate. If it doesn't closely resemble the real - world scenario, the test results can be misleading. And sometimes, the testers are under too much pressure to complete the tests quickly, leading to sloppy work and missed bugs.
A common error is getting emotional. In some horror stories, the person negotiating takes the employer's low - ball offer personally and either gets angry or sad. This can cloud their judgment and make the negotiation go south. Also, not having a clear bottom line is a mistake. People sometimes go into a negotiation without knowing the least amount they can accept, which can lead to accepting a really bad deal.
One common mistake is using unsterilized tools. Just like in the story of the self - stitched wound, non - sterile needles and thread can introduce all kinds of bacteria into the body. Another mistake is improper diagnosis. People often misjudge their conditions and try treatments that are completely wrong for what's actually wrong with them, like the man with back pain.
In holiday marketing horror stories, a frequent error is not doing proper research on the target audience. If you don't know what your customers want during the holidays, your marketing can go very wrong. Also, partnering with the wrong influencers or celebrities can be a disaster. Just like that case where an influencer had a scandal right before promoting a brand's holiday campaign. Additionally, poor inventory management based on inaccurate marketing forecasts often leads to problems. If you order too much or too little inventory, it can hurt your business during the holidays.
