Going to start working on React again!

One main thing in landing your first tech job is a good portfolio page. Currently my page looks like shit and nobody actually wants to pull any of your projects from Github to look at your work. You need to make it easy peasy for them.

My coding bootcamp's curriculum on React was absolute garbage but one of my cohort classmates recommended this tutorial on learning react. I'll let y'all know how it goes!

how to study

“It does require some knowledge and confidence to think out a subject in view of one's experience. When we are somewhat familiar with a subject, some ideas in regard to it may come very readily, so that the first few minutes of reflection may be easily spent and fairly rewarded. But the ability really to think is tested after this period. Then we must know how to overhaul our past and must have faith that we will get something from it. We must search our experience through and through, viewing it from one point and then another in the keen lookout for suggestions.

And we must know that many of the best thoughts, probably most of them, do not come, like a flash, fully into being, but find their beginnings in dim feelings, in faint intuitions, that need to be encouraged and coaxed before they can be surely felt and defined.... Thus vague premonitions furnish the clew to much of the best thought. Very often one of the chief differences between a thinker and one who cannot think lies in the attention given to premonitory feelings of pleasure, discomfort, doubt, suspicion, etc.; the latter ignores such, while the former, when he lacks clear ideas, or all ideas, even shakes himself to discover how he feels, and patiently labors to define his feelings and trace them to their source.

But how dependent such study is upon self-confidence! Unless we have faith in the richness of our own experience, and belief that a careful inspection of it will be rewarded, we lack the courage and patience necessary for success.

How can such confidence be cultivated? Mainly by cultivating the habit of turning first to self when reflective thought is required. It is presupposed that we must consult the library and the world about us for raw facts of various kinds, for historical events, scientific data, views of men, descriptions, etc.; but when our own thought is wanted on a topic with which we are somewhat familiar, and on which we are supposed to have some ideas, let us form the habit of turning to ourselves first; to others as helps later. If other authorities are consulted first, there is danger that the first impressions, the first thoughts, of the student will never come to light; the ideas of others will hide these and become their substitutes, thereby engendering distrust in self.

But by giving attention first to self, by giving it the first chance, its contributions can be recognized; that encourages it to grow and attain vigor, so that, when outside helps are later consulted, it can react upon them and maintain itself. Every young person should do enough thinking on a subject, before attempting to find what others think about it, to have something to oppose to these others, as a basis of judgment. That will keep the self upper most and cultivate the confidence desired. If, on the contrary, we wait until we have found what others think, before attempting to find what we think, others will do our thinking for us, and we will ever be suffering from the timidity that Emerson laments in the words: — A man should learn to detect and watch that gleam of light which flashes across his mind from within, more than the luster of the firmament of bards and sages. Yet he dismisses without notice his thought, because it is his. In every work of genius we recognize our own rejected thoughts; they come back to us with a certain alienated majesty. Great works of art have no more affecting lesson for us than this. They teach us to abide by our spontaneous impression with good-humored inflexibility then most when the whole cry of voices is on the other side. Else to-morrow a stranger will say with masterly good sense precisely what we have thought and felt all the time, and we shall be forced to take with shame our own opinion from another." (Emerson, essay on Self-reliance.).” -F.M. McMurry, How to Study and Teaching How to Study (1909), p278-280

New Research Raises Concerns About the Dangers of Marijuana Use

Whatever your personal position on the subject of marijuana legalization, whether for medical or recreational use, a growing body of research reveals concerns over the potential harms caused by cannabis.

The concerns are more than academic. With increasing public support (varying by demographic cohorts) for legalized marijuana, and 10 states legalizing recreational marijuana and 33 states where medical marijuana use is legal, the cannabis movement is just gaining steam.

A new Pew Research Center report shows that 6 in 10 Americans (62 percent) say marijuana should be legal. Millennials support legalized marijuana more than any other group (74 percent), followed b Gen Xers at 63 percent, and Baby Boomers at 54 percent. The Silent Generation shows the least support for legalized marijuana at 39 percent, although they have shown greater support in the last year.

Long-Term Use of Cannabis of Cannabis-Based Drugs Impairs Memory

Researchers from Lancaster and Lisbon Universities studied the effects of a cannabidiol drug in mice and found disturbing results:

Long-term cannabis exposure impairs memory and learning in the animals.

Brain imaging studies showed functional impairment in key brain areas involving learning and memory.

Underlying the drug’s negative effects on memory may be the fact that long-term exposure causes impairment in brain regions involved in learning and memory to communicate with each other.  

Researchers noted that while cannabis-based therapies can be effective in both treating symptoms of chronic diseases such as epilepsy and multiple sclerosis and in improving the quality of life for patients, much more should be learned about the side effects of these drugs so that interventions can be developed to minimize them.

There is also a marked difference in cannabis used for medical reasons versus non-medical use. While prolonged cannabis intake may re-establish equilibrium in those with certain disease conditions (such as epilepsy or multiple sclerosis), but long-term cannabis use creates marked imbalances in healthy individuals.

Vaping Cannabis Produces Greater Negative Effects Than Smoking the Same Dose

In a small study of infrequent cannabis users, researchers at Johns Hopkins University found that vaping cannabis results in increased rates of short-term anxiety, distraction, memory loss and paranoia compared to smoking the same doses. Researchers said that because of increased legalization of cannabis, they wanted their study to be more representative of infrequent or first-time cannabis users who may not understand or be able to predict the drug’s effects. For example, infrequent cannabis vapers should be cautious about how much cannabis they vape, and avoid driving for several hours after use. They should also be mindful of the side effects they may experience, including anxiety, nausea, vomiting, and hallucinations.

Tests also showed vapers of cannabis demonstrated more functional impairment in driving and performing everyday tasks than cannabis smokers. Researchers also noted that these effects were observed in infrequent cannabis users and may not apply to routine cannabis users, who may have developed drug tolerance and may also be better able to regulate their dose. The study, published in JAMA Network Open, was funded by the Substance Abuse and Mental Health Services Administration (SAMHSA).

More Than Half of People Using Marijuana for Chronic Pain Drive While High

Another concerning finding is highlighted in a study conducted by researchers at the University of Michigan’s Addiction Center. According to their study, funded by the National Institute on Drug Abuse (NIDA), and published in the journal Drug & Alcohol Dependence, more than half of medical cannabis users taking the drug for chronic pain say they’ve driven while high within 2 hours of using at least one time in the last 6 months.

Michigan, with nearly 270,000 medical marijuana users (as of May 2018), is second only to the state of California in terms of highest number of medical marijuana patients in a state.

Lead author, Erin E. Bonar, Ph.D., calls the study results “troubling,” and said the safest strategy “is to not drive at all on the day you use marijuana.” Fifty-six percent of study participants said they drove a motor vehicle within 2 hours of using marijuana. Alarmingly, 51 percent said they drove “a little high,” and 21 percent said they drove “very high.”

The dangers of medical marijuana use to driving include:

Reaction time and coordination may be slowed down.

Drivers could have a harder time reacting to the unexpected.

In a risky situation, such drivers could be more likely to be involved in a crash, because their response time wasn’t quick enough.

Bonar indicated that chronic daily users might have even longer-lasting effects of the marijuana lingering in their system. The study was conducted before Michigan became the 10th state in the nation legalizing the recreational use of marijuana (November 2018). In an email, Bonar said they followed these study participants for 2 years and have “just scratched the surface of the wonderful information they provided us,” adding that there will be more papers forthcoming as her group analyzes the data.

Cannabis Use Appears to Increase Risk of Prescription Opioid Use Disorder

A 2017 study published in The American Journal of Psychiatry found that, rather than decreasing risk, cannabis use appears to increase the risk of developing non-medical prescription opioid use and opioid use disorder (OUD) in the U.S. Researchers assessed prospective associations between cannabis use at wave 1 and nonmedical prescription opioid use and opioid use disorder at wave 2. Researchers also did corresponding analyses of adults with moderate or more severe pain, along with nonmedical opiate use at wave 1.

Noting the long-standing controversy over the extent to which cannabis use predisposes subsequent use of opioids and other substances of abuse, researchers said their findings showed “that cannabis use, even among adults with moderate to severe pain, was associated with a substantially increased risk of nonmedical prescription opioid use at 3-year follow-up.” They also said that while the great majority of cannabis users did not go on to initiate/increase nonmedical use of opiates, caution should be used in any ongoing cannabis policy discussions and clinical debate on authorizing medical marijuana to reduce nonmedical use of prescription opiates and combat opioid overdose deaths.
