It is very hard to not think about what is next, either years from now, or the unknown in general. We have to plan, it is in our natural makeup, but I try and keep my short-term goals in mind. Getting my exercise in and keeping my mind as positive as possible.
Christmas is also a time of giving. Not just in a materialistic way but through so many other ways. Giving of your time. How does that make you feel when you are helping someone else? I get so fulfilled inside when I can help others.
Volunteering at the hospital has been an amazing journey for me, yes, helping others, but I get incredible therapy for myself as well. I talk with patients about my journey and hopefully help them with theirs. ?

My season pass for Universal Studios Hollywood was going to expire soon and I had been to Universal Studios only once since I got the pass. Finally, just two days before the pass about to expire, I and my friends decided to relive the magic of Harry Potter world!
Even thought it was a Saturday, it was surprisingly less crowded for a weekend. That worked out well for us. We did not have to wait in line for any of the rides that we went on. Well, apart from it being less crowded, we tried something else to avoid the long wait lines. We went into the single rider line instead of the general line. That way we were in front of the line and we also happened to sit next to each other on all the rides. It was a win-win!
As far as we know, the last time a woolly mammoth roamed mainland Alaska was almost 12,000 years ago. And even if it sounds like a fairytale, some people think mammoths might once again stomp around in the far north.
And so I tried to rewrite my code in Julia using Optim.jl, with Optim.LBFGS as the method. Unfortunately, my situation is the opposite of Optimize performance comparison - Optim.jl vs Scipy.
Here is my benchmark output:
It is possible that the number of line searches per iteration is different. Apparently scipy defaults to a maximum of 20. I could not find quickly to what Optim defaults. It is not clear to me if either allows you to change that.
I am not sure, the documentation is not very direct. But both which algorithm and how many steps of this algorithm are used at each iteration of LBFGS will affect the final result. Note that these options are very problem-specific (one may question why Optim has one set of defaults and Scipy another, and that probably has not deep reasons or maybe have been defined by some specific test set, and you can get very different final performances depending on the problem you are dealing with).
Optimization algorithms are like that, after choosing one, one has to figure out which is the parameter set of the method that best fits our problem, and by chance the default choice of one or other implementation may be better for our own case.
This makes sense since your function evaluation is faster in Julia. The difference you are seeing almost certainly then related to some of the parameters of the methods. Both methods certainly call the same implementation of LBFGS under the hood, so unless there was a very odd bug in the interface, there is not much more that can differ.
Concerning the derivatives: if you need really that to be fast (and what you have is not enough), you may have to think carefully about that implementation of your function. If it is supposed to be differentiable, than you should pursue re-implementing it such that it becomes so. You may want to start a different thread about that, if you reach some barrier.
ps: maybe you can file an issue in the Optim github with your example, it is possible that some developer takes a closer look at that and finds exactly the reason for the difference and, who knows, decides to change something.
What one has to think is if the model is differentiable or not, in principle. It it is, it can be done (even if by hand). How complicated is that is another story, but depending on the importance of that, it may be worth the effort.
I did it multiple times with different versions. The strange thing is - I downloaded tarball with installation manually and I found that the bundled mongod is for x86 architecture. I tried to replace it with arm64 version I installed separately but again I got the same error.
Second, is it possible to detect arch when running the install script and then install the native version of MongoDB? From reading the MongoDB community edition documentation, it no longer looks possible to do so without homebrew and so all installs are global ( -mongodb-on-os-x/)
Two years into Taliban rule, the question of whether Afghanistan would once again become a safe haven for international terrorism remains alive. Longstanding fears were affirmed a little over a year ago, when the U.S. government located al-Qaeda leader Aimen al-Zawahiri in Kabul, Afghanistan, before killing him in a drone strike. The fact that the Taliban would bring Zawahiri back to Kabul, despite repeated assurances to U.S. negotiators both before and after the Doha agreement that they had distanced themselves from al-Qaeda, significantly elevated concerns.
In the first year of Taliban rule, al-Qaeda began to rear its head in Afghanistan. The group started messaging more actively. Its then-leader Zawahiri issued more statements than he had in a long time, with some inciting violence. Zawahiri's presence in Kabul, Afghanistan, marked the peak of al-Qaeda's post-takeover activity.
However, since then, al-Qaeda has been relatively subdued, even remaining silent about the killing of its leader as reports surfaced that the group appointed Saif al-Adl to succeed Zawahiri. Last week, in the most significant incitement of violence by the group over the last year, al-Qaeda central leadership issued threats against Sweden and Denmark, calling for the targeting of their embassies across the world. In a recently declassified report, the U.S. intelligence community assessed that al-Qaeda lacks the capability to pose a threat to the United States through 2024.
Among Central Asian jihadis, Tajikistan-focused jihadis that are part of the Jamaat Ansarullah attempted cross-border infiltration and attacks, while the Turkistan Islamic Party also remained in the country.
However, ISIS-K still managed to conduct some high-profile attacks, including killing two Taliban provincial governors, as well as attacks in neighboring Pakistan and Iran. It has also demonstrated signs of integration into a strong transnational network, with reports that the group is receiving funding and guidance from ISIS in Iraq, Syria and Somalia and providing direction to operatives in Maldives. The group appears to regularly transmit funds for plotting activities, with indications of active and foiled plots. While there were reports of disruptions in ISIS-K propaganda, recent releases by the group suggest that its propaganda is back on track.
On the face of it, the Taliban insist they are committed to denying the use of their territory by terrorist groups against other countries. However, closer examination reveals that the Taliban's policy toward militants has three main facets: enablement, restrictions and crackdown.
The Taliban enable various militant groups by providing them continued haven and safety within the country. The Taliban also do not restrict the movement of at least some of these militants inside the country. Moreover, the Taliban provide welfare payments and access to weaponry and ammunition to allied groups, among other forms of material support.
Yet this enablement often comes with certain restrictions. For instance, the Taliban seem to have asked al-Qaeda to not undertake attacks against the United States and its allies, as indicated by both U.S. intelligence assessments and al-Qaeda's own messaging. Additionally, the Taliban prevent groups within the country from disclosing their locations in their propaganda. This has led to AQIS releasing written materials without accompanying videos. The TTP also denies being based in Afghanistan.
More recently, the Taliban have attempted to discourage their own fighters from joining foreign jihadist groups. The extent to which the Taliban can exert actual control over this complex militant environment remains unclear, but indications suggest that the Taliban have a formal apparatus as part of the GDI to manage foreign fighters within the country.
Terror groups in Afghanistan appear to remain resolved to long-term campaigns against their respective adversaries. The TTP appears to be moving most aggressively, building up its organization and expanding, whereas others, like al-Qaeda, appear circumspect.
The United States should maintain the international coalition of withholding full normalization of ties with the Taliban and other terrorism-related sanctions until there is demonstrable proof that terrorist groups are being denied safe haven in Afghanistan. To reinforce the over-the-horizon posture, the United States should beef up counterterrorism-specific intelligence analysis capabilities consisting of analysts, linguists and screeners available to the military while also expanding the Rewards for Justice program to generate leads. The terror landscape in Afghanistan remains highly uncertain and dynamic, requiring significant vigilance.
Each year, the U.N. International Day of Living Together in Peace reminds us that true, sustainable peace is achieved not simply by eliminating war, but rather by building tolerance, inclusion, understanding and solidarity among and between communities.
From wars in Ukraine and the Middle East to rising tensions in the South China Sea, there is no shortage of crises to occupy the time and attention of U.S. policymakers. But three years after the U.S. withdrawal from Afghanistan, the threat of terrorism emanating from South Asia remains strong and policymakers need to be more vigilant. Indeed, at the end of March, an Afghanistan-based affiliate of ISIS launched a devastating attack outside of Moscow, killing over 140 people.
