More on the **final logistics**: those of you who requested a conflict, please check **compass2g/grade center**, *Final_Conflict* column: if you see the name of your conflicting course, your conflict request was granted; if you see *Need Doc, *or nothing*, *please send to your TA or me the screenshots showing your enrollment into the conflicting course and its final date/time.

- Lecture notes.
- There are no homework assignments this week; just don’t forget to submit the part C for week 14 on Monday.

Grade cutoffs: what you get if your final grade is above the header on the left, but strictly below the one on the right:

As I found the FAQ provided by the campus a bit lacking, I collected below a few points worth noting. (The prospectus, a.k.a. “white paper” on Falcon Enterprise can be found here.)

- Falcon Enterprise is a big, distributed solution. The computers of faculty and staff and campus servers with Falcon installed will run “sensors” – essentially, programs doing deep inspection of what is stored in memory, what processes are running and what traffic goes through ports. The
*sensors*would, of course, have full access to filesystem, – and justly so: to catch a virus, one needs to look*inside*a file, not only at file header. This is not very dissimilar to what the traditional anti-virus software, which looks for fingerprints (from a regularly updated database) of malice in the files on the computer or server. - What is
*different*in the Crowdstrike solutions, is that these data are constantly sent back to the Crowdstrike servers, to be run through their proprietary system. The advantage of this is, of course, that the outbreak of mass infection on a network can be detected faster; and the culprits can be (sometimes) explicitly identified, which (again, sometimes) facilitates remedial actions. - The data Crowdstrike collects on endusers’ – ours, – lap- and desktops are stored at Crowdstrike servers for a few weeks. These data nowhere close to comprehensive, of course. But we don’t know exactly what is sent up to the mothership. (Given Crowdstrike’s claim that their software is AI driven, that is learning on the fly of the emerging threats, they don’t explicitly control what is sent and stored either.)
- Nonetheless, humans aren’t fully out of the loop: the white paper promises a dedicated team that will be monitoring our data 24/7 as they flow into their system. Campus IT personnel will also have – tightly regulated and bound by various legal constraints – visibility into our computers.
- Overall campus cost are about ~$300K for setup and ~$500K/year to operate. This, however, assumes that the install base is around 48K computers, which brings into focus the big question:
- Who will be forced to install it on their computers? Right now IT FAQ says that only campus owned machines will need to get Falcon installed. We have about 5,5K faculty (tenure/tenure track, specialized and visiting) and about 8K of staff members, which of course includes facilities management etc. Do we really have about 4 networked computing units per person?

In summary: Crowdstrike’s Falcon Enterprise is a cutting edge IT-security solution, an appropriate answer to modern era unprecedented cyber-threats. Correspondingly, it is unprecedentedly intrusive, to the degree similar to tools run by financial or military organizations.

The exam will cover primarily the notions, theorems and techniques of integration, through week 7, but *without improper integrals* (we will talk about them a bit more). Some limited flashbacks to limits and differentiation are to be expected.

It will be again a multiple choice test: 30 problem test timed to be completed in about one hour (still, you will have 1h30m to solve them).

The **problems** will be similar to those you had in the homework assignments.

**Important**: if you require special accommodation through **DRES**, please contact them right away to schedule your exam; we will provide them with the test; they will conduct the exam at the time and environment convenient to you.

**Update**: the results of midterm 2 are in compass; here are the basic stats.

**This week **we will review the material related to midterm topics on Monday. On Wednesday we will finish discussion of improper integrals, and start discussing some applications of integrals, starting with computing volumes. There will be no class this Friday (to compensate for the midterm trauma).
