Carl Mungazi is a frontend developer at Limejump in London. He is a former journalist and switched to programming in 2016. Today the panel is discussing the benefits of reading source code. Carl began reading source code because he came into programming late and from a different field. His first project was with Mithril, and he read the source code and documentation to help him understand it. The panelists discuss how reading the source code has helped them and others to improve their coding. They compare reading and understanding source code to learning a foreign language, and discuss  different methods. 

Carl gives some suggestions for reading source code effectively. He advises people to be patient and step through the code. Accept that you will probably take a wrong path at some point or another, but the more you read, the more you will see patterns in how libraries are structured. He also encourages listeners to approach the authors, as they are often happy to lend a hand. Reading source code is an active approach of stepping through, debugging, putting in break points, checking the stack, and so forth. It’s also important to do outside research. 

Since he has been reading source code, Carl has come to prefer plain JavaScript and libraries with as little code as possible. The panel discusses the benefits of small, simple libraries. Carl gives examples of techniques that he learned from reading a library source code and how he applied it to his own coding style. Reading source code has made him more careful about mixing logic and UI, and now he separates them. He also is more confident in seeing a problem, going to a preexisting library, and just importing the fix for that problem rather than the whole library. Reading source code is really about understanding the code you use in your project. It may slow you down, but you’ll be thankful in the long term because it will help you solve future bugs more efficiently. Carl talks more about his debugging process. He still relies on a debugger, but reading a library helps you to see patterns and guess the output of a function. These patterns persist in other libraries as well. Once you can guess correctly what will happen, you go back to reading the code and find instances where the output is unexpected, and fix it. Carl’s closing thoughts are that through reading source code, he has learned that although code is used differently in each library, they are all written in the same language, and therefore interrelated. This gave him more confidence in reading code because they’re all fundamentally the same. When a bug is discovered, he encourages listeners to look at the source code before googling a solution.

Cyberabad and Rachakonda police have appealed to migrant workers to remain patient and wait for their turn to go home. They even asked them to consider taking up available work in the city. Cyberabad commissioner V C Sajjanar conveyed that the government has made arrangements for safe travel of the migrant workers to different states. “But, as train services are very limited and the receiving state governments have to consent the movement, it will take time,” Sajjanar said.

With no definite treatment protocol in place and a vaccine yet to be introduced, a coronavirus screening survey in the state looks likely. Asha workers are likely to get the responsibility to conduct this survey. “They (Asha workers) are already burdened and any additional work will need additional payment. This needs to be worked out” said an official adding that each worker can be allotted about 1,000 people and a decision may be taken soon.

Telangana industries minister KT Rama Rao has asked European diplomats and representatives of European Business Group (EBG) to consider investment opportunities in pharma and life sciences, IT, defence and aerospace, and textile sectors in the state. Assuring them of all possible assistance from the state, KTR appealed to the diplomats during a video conference on Thursday to support the government in attracting investments. “I will be interacting with the heads of industries from various countries soon,” he said.

Two persons died and four of their friends were injured in a road accident on Wednesday evening at Shankarpalli. The person driving the car, Satish, was allegedly in a drunken state and lost control over the car, following which it landed in an agricultural field.

Taking a serious view of the government’s decision to conduct fewer Covid-19 tests, the Telangana high court on Friday wondered how it would get a true picture of the spread of the virus in the state. The court was also upset with the government for directing doctors not to collect blood samples from dead persons and not conduct Covid-19 tests on them.

Wary about a sharp spike in kidney patients testing positive for the novel coronavirus, the state government has asked the private hospitals to keep the health officials in the loop on those undergoing dialysis.

The wait to return home might finally come to an end for the thousands of migrant workers from West Bengal, stranded across Telangana. On Friday, the Mamata Banerjee-government announced that special trains will be arranged to ferry home migrant labourers, patients, students and stranded tourists.
