Hitchhiker's guide to database types
- Imagine you can't use a dedicated database system for your need to "organize a collection of data which can is stored and retrieved from a computer system." What would you do?
- In my opinion, adequately designed filesystem layouts (that is: directory structures and file naming conventions) are an often overlooked method to solve the database problem.
- To summarize, with a relational database engine you get a centralized state machine, state transitions into a new one with every transaction while ensuring that the structural and enforcing referential integrity of your data at every single point of time.
- As a relational database is designed to hold to the ACID properties, scaling such data is hard especially when several servers are required.
- While some people try to solve different problems with the same tool (=database), but I think it is essential to understand the use case and get the best-suited tool to do the job.
New Zealand mourns mosque attack victims in national day of reflection
- At almost the same time as when the attack was first reported to police, Christchurch ground to a halt for two minutes.
- Hundreds stood, their heads bowed at the memorial wall at the Botanic Gardens where flowers have been laid all week.
- In Hagley Park, a short walk from the Al Noor mosque where most people were killed in the first attack, thousands of people attended a memorial service before Friday prayers.
- Across town, 26 victims of the mosque attacks with be buried at Memorial Park Cemetery on Friday, according to a statement released by Christchurch City Council.

US slaps sanctions on 2 Chinese firms doing business with North Korea
- A senior administration official told CNN that this action should not be seen as a sign the US is ramping up economic pressure on North Korea but as part of the continuous push to ensure that entities and countries are not taking their foot off the gas pedal.
- With these new sanctions, the Trump administration is reiterating that it will not cede to North Korea's demands.
- The Trump administration has sanctioned 182 persons or entities for North Korean violations since March 2017 but only 26 since February of 2018, according to research from the Foundation for Defense of Democracies.
- For now, the administration believes the sanctions are working, and that more effective enforcement will have to come from influential countries, like China.
- Despite the Trump administration being in the midst of trade negotiations with China, Bolton also pointed a finger directly at Beijing when he discussed the new sanctions on Thursday.
Facebook wants to share more local news, but it’s having trouble finding it
- Called Today In, the idea was that Facebook — which is flooded with all kinds of photos, videos, ads, and events from a wide range of people, publishers, and brands — wanted to create a special section where local news and events would stand out among the crowd.
- The darkest green areas are counties in which Facebook saw at least five local news stories posted on Facebook — either by users or by news publishers — every day in the last 28 days (Facebook collected the data on a city level but aggregated it for county-level maps).
- Roughly 35 percent of Midwestern, Northeastern, and Southern Facebook users couldn’t have seen more than five local news stories on Facebook about their town on any single day over the past four weeks, according to Facebook.
As Brexit gets underway, Yale's Stephen Roach says the 'imperfect' EU may not survive
- As U.K. Prime Minister Theresa May presses on to take Britain out of the European Union, one leading economist raised questions about the viability of the single political and economic bloc.
- Even before Brexit came about, the EU faced multiple challenges over the last decade, said Roach, who's a former chairman of Morgan Stanley Asia.
- — one of the largest European economies — planning to leave the bloc, it remains to be seen whether the EU has the ability to withstand more pressure coming from member states while still reeling from the shocks of the global financial crisis, said Roach.
- If May fails to convince parliament, Britain would face a disorderly exit from the EU on April 12.
- Even though the circumstances surrounding Brexit are still uncertain and pose a major risk within Europe, Roach said the event itself wouldn't be enough to derail the global economy.
Request for Documents in Latest Trump Probe Comes Up Short
- The probe is headed by House Judiciary Committee Chairman Jerrold Nadler, who sent document requests to 81 separate agencies as a means of investigating “alleged obstruction of justice, public corruption and other abuses of power by President Trump.” The deadline for submitting related documents was last Monday, yet only eight of the contacted agencies provided responses.
- Ultimately, people must respond to us unless the President personally votes an executive privilege, which is a rare thing… They have no immunity.
- However, an anonymous republican committee aide has reported that very few people have responded to Nadler’s request.
- The report suggested that electronic voting machines had been vulnerable to cyberattacks between the years 2000 and 2006.
- One respondent, former Trump adviser Michael Caputo, says he was the first to answer Nadler’s request, but that he ultimately didn’t possess any of the documentation the Chairman was looking for.
Nintendo's Labo turns the Switch into a perfect VR gateway
- Nintendo proved that its cardboard Labo kits could actually be decent gaming accessories -- especially for kids.
- After trying out a few Labo VR Toy-Cons at a media event, I came away impressed with what Nintendo managed to accomplish with the Switch's limited hardware.
- The Switch slides into the front, and you can then plug in the goggles to other Toy-Cons, like the Blaster.
- These are just a handful of the experiences the Labo VR kit offers, but they're enough to make me think that Nintendo actually understands what it's doing.
- Like Nintendo's previous Labo kits, there are also Garage modes that'll let kids create their own experiences in either 2D or VR.
- You can snag the entire Nintendo Labo VR Kit for $80, or get the starter pack for $40, which includes the Goggles and Blaster.
How to Think of Your Career as a Series of Stepping Stones
- If you want a fast-moving career, think of each job as a stepping stone.
- I was looking to keep my career moving and jump to the next stepping stone.
- It was no coincidence that the employer that was looking to hire someone to do Node.js was also willing to hire someone based on eagerness to learn instead of years of experience.
- You can stay with PHP or enterprise stacks like Java or .NET for a solid, stable career: but generally speaking (and ignoring the expections) don't expect to find fast-moving, risk-taking employers in those stacks.
Dear Mr. President, stop railing against John McCain
- Editor's Note: CNN national security analyst John Kirby, a retired rear admiral in the US Navy, was a spokesman for both the State and Defense departments in the Obama administration.
- Let's put aside that he is, without question, a war hero.
- Let's even put aside the fact that his family -- and this nation you are supposed to be leading -- still mourns his passing.
- John McCain served his country.
- I suppose there have always been people of low character in elected office -- charlatans who prey on our fears and feed on their own sense of personal grievance or glory -- but in that malevolent effort they cast aspersions on the vast majority of elected officials who truly just want to do right by their country.
- It hurt because it came from the likes of John McCain.
- A man like McCain comes along only once in a generation or so.
She was once the smallest baby born in Texas. Now, she works in the NICU of the hospital that saved her life
- But Lewis beat the odds and now, 34 years later, she works in the same NICU that saved her life.
- Lewis spent the first 3½ months of her life in the NICU at Scott and White Hospital, now named McLane Children's Medical Center Baylor Scott & White.
- Years later, she works alongside some of the same doctors and nurses who treated her as an infant.
- The hospital features her on its "Hall of Hope," where it highlights babies with difficult journeys who have survived.
- Lewis said workers in the NICU become like a part of the patients' families, because they work so closely monitoring the infant, all with the goal of getting the babies healthy enough to go home.
- A highlight of her work, Lewis said, is seeing those babies come back to visit.
